RE: Genesis ARF build, its here.
Looking good Mike, I'll bet you’re anxious to get that baby in the air!
One more thing I thought I'd mention. Did you fuel proof the inside of the pipe tunnel and the engine compartment, or does it come already fuel proofed?
The reason I ask is that sometimes the fuel can soak through the fiberglass and start eating the paint from the backside, depending on the type of paint. If they used a fuel proof paint this isn't a concern, however, I've heard people mention the paint becoming damaged around the pipe tunnel cutouts which suggests that the paint may not be fuel proof, but the clear coat over the paint is fuel proof.
If the pipe tunnel and engine compartment are not fuel proofed this can be done very weight economically by using 30-minute epoxy and cutting it 50/50 with acetone or denatured alcohol. This thins the epoxy significantly and makes it very runny. You can then brush the mixture on and the alcohol or acetone will evaporate off and you're left with a very very thin layer of epoxy that will fuel proof your fiberglass.
To get down the pipe tunnel I use a dowel with an epoxy brush taped to the end.
