Single and two seat Mig 15's I've just painted for Andy. These are 600mm (24") span profiles with mid mounted motors.

Note the cheeky heat bluing around the back of the single seater

Cut files are below for anyone wishing to make their own. I've also included a few build pics from Andy, as there seems to be quite a bit of interest in the Miggy's....Continue Reading

As well as the Mega-Plasma, Andy Whitehead and I planned to come up with something a little different for this years Electric Indoor Masters and so decided on a scaled up version of Flying-Dog's Gym-Star, with Andy doing the design/cnc cutting and myself the building and airbrushing. Because we were on a bit of a tight dead line we made the decision to, rather than a built up wing, go instead with a milled flat plate from 6mm depron, which did work very well. The wing has a single piece of 1x6mm carbon strip along the leading edge, the rest is braced with a 3.5mm tube A frame, which when rigged results in a surprisingly rigid structure.

Andy as always did an amazing job with the design, especially considering there was no dry run the whole thing fitted together pretty much perfectly.

Here are a few specs:

Wingspan: 1500mm (60 inches)
Length: 1300mm
Weight: 530grms

Motor: Turnigy 2217 20turn 860kv 22A Outrunner
ESC: Hobbywing 25amp
Battery: Turnigy nano-tech 950mah 3S 25~50C Lipo (chosen because it only weighs a scant 69grms!)
Aileron Servos: HXT 9grm
Flap Servos: HXT 5grm
Elevator/Rudder Servos: Turnigy 9grm MG
Prop: APC 12x3.8 SF
