Flight Line PlansTM : Micro Models
Flight Line Plans are a well-respected producer of electric R/C and free flight aeroplane plans. Designs are available in several categories: Micro Models, SmartDarts, Flying Wings, Sports Aerobatic, Vintage and Trainers. Flight Line Plans also provide kit packs for some of the micron designs - these comprise materials, additional drawings and a cutting template. Some designs are available as complete kits.
These micro models are intended for indoor flying or outside flight in sensible conditions. Construction is mostly from thin depron with colouring applied using thinned acrylic paint or poster pens.
The AT10 is a 10" (250mm) span micro RC trainer. AT10 is short for 'Actuator Trainer 10" span' and if you have never tried using actuators before or micro flying then this design is an ideal introduction to micro flight.
AT10 is simple to construct and set-up. It is powered by a 7mm motor supplied from a single LiPo cell. You can choose either the Micro Invent or Plantraco radio gear driving rudder and elevator actuators - although the plan is drawn with the excellent Micro Invent Minor receiver and MCA1 actuators, using the Plantraco 0.9g receiver and micro actuators is just as easy. Flight times are in the 13 - 17 minute range and the all up weight is only 14g.
It is remarkable how well this model flies on just a couple of watts of power and will loop and stall turn easily. The picture on the left illustrates the diminutive size against a standard Futaba transmitter.
The AT10 plan is annotated with building instructions and control setup. An optional pack of all building materials is available - see the 'Options' tab.
Specifications:
Materials Needed to Complete: The following materials are required to build AT10 from the plan and are included in the kit pack option.
Required Radio Equipment:
A number of options and two airborne packages for AT10 may be purchased at discounted prices. Selecting an option will add its price to the total. Please take care when making option selections as not all of the Micro Invent options will work with Plantraco - and vice versa. Take a look at the 'Package' menu if you need to purchase a complete set of radio gear - call or email if you are unsure.
The kit pack option includes all depron, balsa wood, carbon fibre, wire and sundry materials along with additional drawing(s) and a cutting template. All you need to add is glue (e.g. Deluxe Materials Roket Odourless and UHU-Por).
Styro spray paint or Zig Posterman pens are ideal for decorating this depron model.
Two alternative packages of airborne components have been selected for you:
The Micro Invent Minor receiver is on 35MHz and requires a micro crystal to match your transmitter. The Plantraco receiver is on 868MHz and requires either the matching transmitter or the Monolith which is a buddy box connected module for Futaba and Hitec transmitters.
The PT11, a 11" (280mm) span micro RC trainer, joins the increasing number of micro models in the Flight Line Plans range. PT11 is short for 'Parasol Trainer 11" span' and is fitted with lightweight undercarriage to allow circuits and bumps.
The model is powered by a 6 mm diameter geared pager motor driving a 100x80 mm prop supplied from a single 90mAh or 130mAh Lipo cell. Radio is the brilliant Micro Invent Minor receiver operating rudder and elevator actuators and with built in speed control. Flight times are in the 10 minutes plus range and the all up weight is only 16 or so grams. Construction is from depron and balsa with colouring applied using thinned acrylic craft paint or poster pens.
As with other Flight Line PlansTM micro RC models, it's remarkable how well this model goes on just 1 watt of power and despite its proportions it flies in a very sedate fashion.
The PT11 plan is annotated with building instructions and control setup. An optional pack of all building materials is available - see the 'Options' tab.
A number of options and two airborne packages for PT11 may be purchased at discounted prices. Selecting an option will add its price to the total.

PT17 is 17" (430mm) span up-scaled version of the original, smaller PT11 parasol wing design that offers a convenient and simple to build 3-function rudder-elevator-motor trainer for modern micro RC gear that is also easy to fly.
PT17 is powered by a '5g' brushless outrunner motor driving a 5"x3" prop supplied from a 2S1P 180 - 200 mAh LiPo battery. Radio can be either a micro 2.4 GHz system such as the Spektrum AR6300 or a 35MHz equivalent such as the Blue Arrow R3P4. Rudder and elevator are controller by conventional 2.5g servos, Falcon 1.6g servos or Toki RC-1 1g servos. A 6A ESC completes the requirement. Flight times are in the 9 minutes plus range and the all up weight with BA R3P4 and 2 x 2.5g servos is around 52 grams. Alternativelly, a Spektrum AR6400 receiver module can be used - this combines a 2.4GHz DSM2 receiver with two on-board servos.
Construction is from depron and balsa with colouring applied using thinned acrylic craft paint. The PT17 plan is annotated with building instructions and control setup.
A number of options for PT17 may be purchased at discounted prices. Selecting an option will add its price to the total.
SmartDart xxs is the latest version of Paul Cook's SmartDart presented as a 10" (250mm) span micro model. This is the fourth Dart in the series with xxs referring the extra, extra small size.
The model is powered by a 7mm diameter pager motor driving a 2.25" prop supplied from a single 150mAh LiPo cell. Radio is the brilliant Micro Invent Minor receiver driving rudder and elevator actuators with built in 2A speed control. Flight times are in the 13 - 17 minutes range and the all up weight is only 17 grams.
The SmartDart xxs plan is annotated with building instructions and control setup. An optional pack of all building materials is available - see the 'Options' tab.

The Micro Invent Minor receiver is on 35MHz and requires a micro crystal to match your transmitter. The Plantraco receiver is on 868MHz and requires either the matching transmitter or the Monolith which is a buddy box connected module for Futaba and Hitec transmitters. The Plantraco transmitter has a built-in charger for the Bahoma (magnetic connector) LiPo cells. If you are not using the Plantraco transmitter you will require a charger suitable for low capacity single LiPo cells, e.g the BiCha charger.
The SmartDart xxs plan shows the detail for installation of Micro Invent R/C components. However, substitution of Plantraco R/C is simple and well within the capability of someone with experience of building one or two models. As the battery is mounted directly onto the Plantraco receiver, its position will require adjustment (moving forward slightly) to maintain the C of G at the point marked on the plan.
WattOne is a brilliant micro flying machine just like a scaled down normal-sized aerobatic model. The picture illustrates the size against some grapes and, despite its diminutive proportions, it flies just like a larger pattern plane, managing rolls and loops.
This 10" wingspan model is powered by a 7mm pager motor driving a 2.25" prop supplied from a single 150mAh LiPo cell. Flight times are in the 13-17 minute range and the all up weight is approximately 15 grams.
The WattOne plan is annotated with building instructions and control setup. WattOne can be built in aileron/elevator form or, for more fun, as a 'full house' rudder/elevator/aileron model. An optional pack of all building materials is available - see the 'Options' tab.
Materials Needed to Complete: The following materials are required to build WattOne from the plan and are included in the kit pack option.
A number of options and two airborne packages for WattOne may be purchased at discounted prices. Selecting an option will add its price to the total.

Three alternative packages of airborne components have been selected for you:
WattNext is a miniature aerobatic plane for the Spekrum AR6400 or Parkzone PKZ3351 receiver modules. WattNext has spectacular performance in either 3 or 4-function mode to control ailerons, elevator, (optionally) rudder and throttle via an external ESC, all from a single Lipo cell. The model would suit capable flyers either for outside use or indoors in a sports hall.
With a span of 16.5" (420mm) it is powered by an AP03 7500Kv brushless outrunner motor driving a U-80 or GWS 3x2 prop supplied from a 250mAh Lipo. Radio is either the Spektrum AR6400 or Parkzone PKZ3351 integrated receiver and 2 x servo module. An external servo and external brushless ESC complete the R/C equipment.
Flight times can be in the ~7+ minutes range and the all up weight is only around 32 grams. Construction is mainly Depron with a balsa fuselage and local balsa strengthening. The finished model benefits from colouring with acrylic paint or marker pen.
As with other Flight Line PlansTM designs, it's remarkable how well this model flies on around only 6 or 7 watts of power and despite its size it flies in an exceptionally stable yet aerobatic fashion. WattNext is capable of all rolling and looping manoeuvres and inverted flight and can be flown both fast and slow due to its light wing loading and high power to weight ratio. Take off distance is about a metre.
The WattNext plan is annotated with building instructions and control setup. WattNext can be built in aileron/elevator form or, for more fun, as a 'full house' rudder/elevator/aileron model.
A number of options and two airborne packages for WattNext may be purchased at discounted prices. Selecting an option will add its price to the total. Please take care when making selections as not all of the options are compatible. Please read the AR6400 and PKZ3351 descriptions to understand the difference between these two modules. Take a look at the 'Package' menu if you need to purchase a complete set of radio gear - call or email if you are unsure.
WattTwo is, naturally, a twin-engined version of WattOne. This 10.8" (275mm) span aerobatic model has been extensively test flown outdoors in light wind conditions and indoors. The picture illustrates the size against a pair of English strawberries and both are a true delight!
Two 7 mm diameter pager motors driving 2.25. props supplied from a single 150 mAh Lipo cell power the model. Radio is the brilliant Micro Invent Minor receiver, operating aileron and elevator actuators and with built in speed control powering both motors in parallel. Flight times are around 9 minutes and the all up weight is only 19 or so grams. Construction is mostly from thin depron with colouring applied using thinned acrylic craft paint or poster pens.
It's remarkable what the doubling of thrust offers and with about 2 to 3 watts of power loops, rolls, wingovers and inverted flight are all readily possible.
The WattTwo plan is annotated with building instructions and control setup. An optional pack of all building materials is available - see the 'Options' tab.
Items Needed to Complete:
A number of options for WattTwo may be purchased at discounted prices. Selecting an option will add its price to the total for the plan.
Twinky is a 14" 1.1oz (355mm 32g) depron flying wing. Great fun to fly indoors or out where loops, rolls, bunts and tight turns are all part of the action. Its low wing loading and ability to cope with a stiff breeze makes Twinky a true back yard flyer.
Twinky uses the Falcon Models Breeze unit for control with a cheap GWS motor for power. Twinky is a very resilient model and has provided hours of fun, giving up to 17 minute flights with 250mAh li-polys. Every flight is a Twinky adventure!
Materials Needed to Complete: The following materials are required to build Twinky from the plan.
A number of options for Twinky may be purchased at discounted prices. Selecting an option will add its price to the total for the plan. A hardware pack comprising pre-cut depron, wood and control linkages will be available shortly. Zig Posterman pens are ideal for decorating the depron model.
PE 100 is a real fun hack whether you want to fly it just as a sports model or as a trainer. It offers a docile performance with 3-function R/C using the Spektrum AR6400 or Parkzone PKZ3351 to control rudder, elevator and throttle via an external ESC, all from a single Lipo cell. The model would suit novice flyers either for outside use or indoors in a sports hall.
With a span of 18.5" (470mm) it's powered by a 2g brushless outrunner motor driving a GWS 2.5" prop supplied from a 200-240mAh Lipo although 130 and 70 mAh sizes have also been used. The integrated R/C module incorporates the RX and 2 servos and allows connection of a single cell 3A ESC. Flight times can be in the ~15+ minutes range and the all up weight is only around 28 grams. Construction is mainly depron with a balsa/depron fuselage and local balsa strengthening.
Two wing variants are detailed on the plan; a simple flat plate section and the curious Kline-Fogleman section KFm2 which is no more difficult to make, yet noticeably stiffer. If you haven't come across this before it's worth the experience. The wing is retained by a couple of small elastic bands to offer a little more crash resilience and allows for easy exchange between the wing types.
It's intriguing how well this model flies on only 5 watts of power and it truly deserves the accolade of being 'Whisper Quiet'. No one could ever complain that it's a noisy model. Don't expect PE 100 to be capable of aerobatics, although it does loop and can just be made to roll but it's not elegant! It's best just stooging around or intermittently powering to height and gliding back down, or doing touch and goes off a fine surface. If you have space to fly from your garden, try it.
The PE100 plan is annotated with building instructions and control setup. ESC connection instructions are provided for both AR6400 and PKZ3351 (Vapor module) receiver modules.
A number of options and two airborne packages for PE100 may be purchased at discounted prices. Selecting an option will add its price to the total. Please take care when making selections as not all of the options are compatible. Please read the AR6400 and PKZ3351 descriptions to understand the difference between these two modules.

Wunwuno is a 9.7" span 'Cartoon scale yesteryear jet' reminiscent of the evocative early '50s DE HAVILLAND DH-110.
The model is powered by a 7 mm diameter pager motor driving a 2.25. prop, pusher style, supplied from a single 150 mAh Lipo cell. Radio is the brilliant Micro Invent Minor receiver operating aileron and elevator actuators and with built in speed control. Flight times are in the 13 - 17 minutes range and the all up weight is only 15 or so grams. Construction is mostly from depron with colouring applied using thinned acrylic craft paint or poster pens with modest insignia additions to complete.
As with the other Flight Line PlansTM micro RC models it's remarkable how well this pusher goes on just 1 to 2 watts of power and despite its proportions it flies in a very spirited fashion managing rolls and loops, inverted flight and swooping passes.
Materials Needed to Complete: The following materials are required to build Wunwuno from the plan and are included in the kit pack option.
A number of options for Wunwuno may be purchased at discounted prices. Selecting an option will add its price to the total for the plan.
