Turbine Trainer w/ WREN 54 Turbine RTF! TURNKEY

Information Specific to Airframe:
This plane is based on a modified and reinforced Right Flyer (Global Models). Control surfaces are rudder, elevator, ailerons, and flaperons (requires basic mixing capable transmitter). The stabilizer and wing have been both modified and reinforced (see pictures). The wing assembly attaches to the fuselage via the conventional method of rubber band. However, I utilize the #84 heavy-duty rubber band (each capable of carrying a load of 15 pounds I'll include a package). In addition, the wood dowels that attach the wing to the airframe have been replaced with stainless steel rods, supported with epoxy-impregnated Kevlar. While many of the components and structures have been reinforced, the goal was to create a trainer aircraft, not an F16-like-super-aerobatic rocket. Plane weighs approximately 11.5 pounds dry.

Will it fly or crash and burn ?
Will it come down in one piece, or shred itself in the air?

I have seen poorly assembled ARF trainers fall apart, fold a wing, have the firewall come loose.....all with cheap 2-strokes on them.


and can I say E-barf here?
I know I am not supposed to mention the competitors name

Sure, it will fly. Just until the rubber bands pop off. Then it will crash. What was the guy thinking? If you get it, change that to serious bolts. Yikes! Rubber bands?

Actually, the wing may fold before the rubber bands let go. He says "reinforced", but I don't see anything, except what looks like a stock wing with a stock lite-ply spar and cheap chinese wood ARF construction underneath. The rudders look like they might flutter off, but you could probably survive that. You may NEED rudder control, though, to guide the wreckage down after the wings pop off, being that the ailerons are attached to the wing and will leave when the wing does.

Well I too beleive it will fly. Well for about three seconds. Look at the wing joint no glass, look at his new vertical stab mount, ny-rod for rudders, Nice.

Actually I am curious as to how he mounted the turbine mount. Man those planes have soft wood, I wonder if it will even get down the runway before the 12lbs of thrust brake the mount.


Turbulence.

[:'(] recipe for disaster it seems.

That rudder setup will start to flutter at 40 mph or something... that looks just horrible! Probably 1" of slop on those things.

I'm sure it will fly, and it may even live for quite a while with proper throttle management... providing the rudders are fixed first.

Rubber bands are fine, providing you use good ones and keep track of them. Also 10 light bands are a lot better than 2 heavy ones (redundancy).
Nothing you would use on a fast plane of course, but good enough on something lightly loaded and slow.

Absolutely disagree on the rubber bands. That thing is going to be, what, 13-14 pounds, fuelled? You think a rubber band is going to hold the wing on? Ever see rubber bands on ANY 13 pound airplane? Much less a jet?ld use on a fast plane of course, but good enough on something lightly loaded and slow.

Yes, it will fly. The question is (and no one here could answer) for how much time?
