Newbie needs advise on very small gymn flyer.

[zoomzoom]

I'm mainly a glow flyer, but have acquired a 17.5 inch-WS Guillows Stuka which I have decided I would love to actually fly as an RC bird. I have seen a few others do this with this size Stuka, but they all seem overweight, and not to mention overpowered, and this leads to my quest. I want to give this machine a very light electric system, power is not the goal, but moreso scale flight, and endurance. A 15 minute flight time per charge is a rough target goal. Any suggestions from those more experienced here will be much appreciated. Of course, the more cost effective will be preferred over the more expensive.

TIA!

My advise, if this truly belongs in the beginners area, is to avoid a Gullows as an indoor RC conversion, due to many factors.

If you prefer to build and re-design, then your Gullows will allow you to be all the flight engineer you can be.

If you want to fly, then go with some indoor flat foamy and be a pilot instead of a builder.

What do you really want to do?

Well, since the machine is already finished, that parts done, so now the fun is in the figuring of the components to make her airworthy.

So what's the weight right now? It will be a big determining factor.

The Parkzone UM power system and integrated RX/Servo brick is very popular. There are few Guillows conversions out there using these.

If it was not built to be flown RC, then you have a substantial amount of work ahead adding ailerons, elevator and rudder. Adding power will be easy compared to the airframe work.

Is it already fitted with moveable control surfaces?

If so, as mentioned weight is a large factor. You need to determine all up weight, so having the servos/rx/controller weights will help but we need to know airframe weight as it is.

Pilipa's suggestion of the UM set is pretty good, lots of success if the weight isnt too much.

The aircraft is already being set up with the correct control surfaces etc etc...and you guys are right, I need to get you the AUW before you can give me ideas. I still need to tissue cover it, so once I do that, I think it will at least be in the ball park. I will get you the weight data shortly.

Thanks!

PS. Am thinking rudder elevator controls.....saves weight from an extra servo for the ailerons, and if the system is chosen correctly, to fly on the wing that is and not be a ridiculous rocket, it should work nicely and be stable with that gull wing dihedral.

R/E only is all you need as long as you have adequate dihedral in the wings.

How is your project coming?
