Yeah I did that with the drill. R/B/W like futaba, total length of aileron extension is only 32" so I should be ok as long as have good solder joints. My project tomorrow is to head down to the hangar and build some isolation mounts for the engine if the weather is too bad to work. I decided to go with the converted ST2500. If I mount on an angle, I should be able to send exhaust out the augmentor tubes. Should look a little better, and being gas I won't have to dork around with glow plugs
