'SkyDart' is the latest iteration of the popular SmartDart models. It is a trainer designed to teach the basics of model construction and would be ideal as a first R/C model. The impetus for SkyDart was the need for a model suitable for use in a school project on flight.

The SkyDart airframe is a balsa open frame construction with Depron skinning. This combines lightness with excellent strength - exactly the qualities you need in a beginners model.

The video tab contains an animation of the SkyDart build sequence. It was created from the CAD files used to generate the SkyDart plan.

'SmartDart', the very first SmartDart of the series. At 27", 7oz and 100W of power, this model will out perform many others. Its large wing area and dihedral make this model incredibly docile. However, crank up the movements and you'll be looping, rolling, prop-hanging and even tail sliding!

'SmartDart xs-f', as much fun as the original 22. 'xs' but now more robust for those indoor sessions. The SmartDart xs-f is constructed from 3mm depron foam with carbon strengthening. The SmartDart xs is now even quicker to build and more likely to bounce on those indoor mishaps.

This version is exactly what you need to learn to fly indoors; incredibly stable and slow flying yet able to loop roll and prop hang all with just rudder, elevator and throttle. The SmartDart family will provide hours of fun for pilots of all skill levels.

Specifications:

• Wingspan: 22" (560mm)
• Flying Weight: 4.4oz (125g)

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.

• 7mm 3.3ohm motor and propeller
• 150mAh single cell LiPo (MI LiPo150P)

A number of options for SmartDart xxs may be purchased at discounted prices. Selecting an option will add its price to the total for the plan.

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.

Kit Pack:	no yes : +£7.45
Motor:	Please select... 7mm 3.3ohm : +£3.35
Prop:	Please select... Tri-Turbofan : +£1.55 GWS 2.5x0.8 : +£0.50
Receiver:	Please select... Micro Invent 35MHz Minor : +£59.25 Plantraco 0.9g 868MHz : +£38.75 Crystals for the Minor rx are available here
Actuators:	Please select... 2 x Micro Invent MCA1 : +£32.90 2 x Plantraco Micro Actuator : +£23.75
LiPo:	Please select... Micro Invent LIPO85 : +£6.55 Micro Invent LIPO150 : +£8.55 Plantraco 90mAh Bahoma cell : +£8.50 Plantraco 130mAh Bahoma cell : +£8.90
LiPo Charge Lead:	Please select... Micro Invent MRC (only required for Micro Invent LiPo : +£1.30

Two alternative packages of airborne components have been selected for you:

1. Micro Invent Minor receiver, MCA1 actuators, 85mAh LiPo, 7mm 3.3ohm motor & triturbo prop (as specified on the plan) plus MRC charge lead
2. Plantraco 0.9g receiver, micro actuators 90mAh Bahoma LiPo, 7mm 3.3ohm motor & triturbo prop

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.

Package:

Please select... Micro Invent R/C & plan : +£104.95 Micro Invent R/C & kit pack : +£112.40 Plantraco R/C & plan : +£75.95 Plantraco R/C & kit pack : +£83.40

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.
