Default RE: .46 Pbox problem with Phoenix Extra Arf


ORIGINAL: tramsay

So i got a Phoenix Extra off Tower for $109 WOW!...would do again in a heart beat. The quality is very nice, with out without the cheap price tag. I already had an 0.S. .46 AX, which is the recommended motor in the user reviews section of RCU.

So I have it all built, but have a problem... The motor is mounted on its side, so the pbox muffler runs down the bottom. With the motor mounted at the recommended distance from the firewall, the pbox runs into the fuselage. Right where the muffler hits the fuselage there is a lightening hole with covering over it. What should I do? How do accomidate the pbox, but keep the fuse closed so slag and fuel won't get inside. All of this will be under the cowl once installed.

What about cutting the covering and building a balsa box inside the nose and then coat it with epoxy or some other fuel proof compound (polyurethane)? Balsa isn't that expensive and it wouldn't take much thickness - say 3/32" to do the job.
