Default Twin SIG Wonder

Has anyone Kit Bashed a SIG Wonder making it a twin?

Mine with two OS.15FP has not been a total success.

Tail stretched 2.75" and dual rudders added, each nacell had fuel tank and micro servo. weight was46.5 oz 4.5 over my projected weight

The 2 oz round tanks would not deliver full load of fuel resulting in one engine out. then P-38 Lightning syndrome---roll over on its back and enter into a spin.

TWIN WONDER II

it will have 42-44" wing, profile style nacells 3 degrees out thrust, one fuel tank in fuse, on throttle servo with wire in tube linkage, micro not standard servo for rudders. and two conquest .15 power.

Any other Ideas??????

look here.....

http://www.rcuniverse.com/showthread...ig+wonder+twin

I bought this plane to leroifort, it's mine now and fly like a blast.

if you read the thread about leroifort's building you will see that he enlarged the wing for reasonable wingload, he also enlarged the stab elevator assembly because of the short tail moment.
you will also find the firewall settings. this plane fly great !!!!

for most .15 this mean manufacture a custom made crankshaft. Maybe a little bit overpriced for this kind of small bird.

it fly great like that with both engines 3 degrees downthrust left engine a zero side thrust and right engine at 3 right thrust
