About this Plan

Supra Fly 25. Radio control aerobatic pattern model.

Quote: "Flying: Though relatively small the Supra-Fly 25 does fly smoothly. I had to fly her a couple of times to adjust the control throws. The reason for this was that no control measurements are shown on the plan or in the instructions so harmonised control does take a little time to obtain. I suggest the following movements as a starting point with the model balanced on the CG with half full (3oz) tank. Elevator up and down 3/8 in at root, ailerons up and down 1/4 in at root, rudder maximum 1-1/2 in each way.

Once balanced the Supra-Fly 25 does groove. Being a small pattern ship the elements can buffet her around more than a larger heavier model, but all in all she does live up to expectations. She will not flick when set up as mentioned unless you input ailerons. A more rearward CG may help.

Summary: Construction and building time can be given a five star rating - it is truly excellent. Two things I found needed a lot of care in the kit were the canopy and the cowling. The canopy required great care in trimming - being PVC it is very, very brittle and will shatter if not cut deeply with a knife. The cowling is moulded out of nylon (squeezy bottle) and is very tricky to paint! The only paint which will really stick I found was enamel, and for me a further colour match was necessary!

Flying the Supra-Fly 25 when trimmed is fun and it does perform very well. Coupled with its small size, transportation is easy, making it a model you will fly a lot even if the car is full of grannies and kids! So it builds easily, flies nicely and does live up to the expectations as placarded. A nice one Hanno!"

Notes

* 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.

Scaling

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.
