RE: BuckShot Quickie 25 Build
Dave, the BuckShot uses 2 pieces of 1/8 plywood sandwiched together and tabbed into the fuselage. I feel with the addition of the fiberglass on the nose gives it extra strength. My first 2 BuckShots actually were silked and doped before painting with no fiberglass and even though both crashed so hard the Hayes motor mount broke the firewall stayed intake with no issues.
Now on the "HoleShot" 424 and my 428 prototype I use 3 pieces of hard plywood notched into the fuselage side and top and bottom plywood. I like to use the slow cure epoxy on these areas because of a better bond and the epoxy has some flex which will absorb the high frequency vibrations seen with the larger engines.This with a double shot of fiberglass has even survived some grass cutting with the Nelson on a few occasions![:@] Here is a picture of the rough sanded fuselage before glassing. You can see the top notch of the rear piece of plywood.
