About this Plan

Aeroflyte Gemini. Radio control sport and multi trainer, for .29 to .40 power.

Quote: "Gemini is a medium sized aerobatic model that is designed for modern 4 channel radio equipment and .30 - .40 size engines. The original model was designed by Ron de Chastel of Brisbane, Australia and has been extensively flown in both two wheel and three wheel versions by both experienced fliers and beginners and its attarctive appearance, ease of construction and exceptional performance, in both low speed handling and high speed maneouvres, made this an ideal model for Aero-Flyte to produce in kit form. The exceptional low speed handling makes Gemini an ideal low wing trainer when fitted with a .30 engine, while a good .40 and a good pilot produce competition winning performances..."

Quote: "Hi, here are the kit plans and instruction sheet for the Aeroflyte Gemini. This is the original version as designed by Ron de Chastel, a well known aero modeller here in Australia, no longer with us. I built this version for a club mate back in the early 80s. It was the aileron trainer to go to back in the 70s and early 80s, after learning on the high wing 3 channel trainer the Aeroflyte Hustler, oz5795, plans also on Outerzone. I have recently seen this version flying at one of our local RC clubs finished as a tail dragger. I plan on building this version sometime in the next 12 months along with a couple of other Aeroflyte designs. Turtle deck formers 14, 15 and 17 do not appear on the plans, but any competent builder will have no problem working out the shapes. Cheers, DaveW."

Steve was not going to the field Sunday, so he invited me over today. Steve still has the original kit box, so I included it in the pics [more pics 003-007]. Steve's Gemini has been fitted with an alloy undercarriage as he found the original wire gear was too short and with no new canopies available he has used a coca-cola PET bottle carved to shape to an acceptable effect. Power is a OS 40H RC from the late 70s as well.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
