g26 engine mounting question
I am new to gas engines and I want to mount my G26 correctly.... the 5ply, 1/4 inch plywood firewall is glued between two balsa sides; these will be strengthened with 1/4 inch balsa siding (also 1/4 inch triangle balsa along the corners). There is no plywood in the side structure. I was told to pin the sides with 1/8 inch dowel inserts (about 4 per side)..... also, since the aft firewall will be hard to get too once finished, do I use blindnuts or would regular nuts with flat washers do the trick? I feel this engine will pull itself free from the mount sides..... probably be fine but I would love some experienced input.

RE: g26 engine mounting question
I have a G-38 in the nose of a plane that only has balsa sides. I just used triagle stock in the corners and glassed the outside corners.... Been fine for 20 years....

RE: g26 engine mounting question
Sounds good; I will add a piece of 1/8 ply to the back, use blind nuts and a lock nut also. I was also told to reinforce the side area with 1/8 ply just to cover 1/2 inch in front of and behind the firewall; then pin the firewall with 1/8 inch dowel pieces from both sides; should be about 3 per side.
Do you think this is overkill? I am alittle worried about weight but the common consensus is to build a proper mount for the G26; the engine will more than make up for additional weight added onto a 9.5 lb airplane.
thanks again.
