RE: nitromodels 63" extra 330
Thanks for the advice. And thanks to everyone on the thread for the great advice on the airplane.
I already changed the stock landing gear to Dubro landing gear. I going to use a little fiberglass and a small screw and I-nut to reinforce the wheel cowls. I did not like using the standard screw that provided.
We did a weight test and determined the 120 will work on the airplane. We are going with an APC 15x8 prop turning the 120 at about 9500 rpm. We are also going to try a 15X6 and 16X4 wide prop. In any case, the 120 will basically pull the plane into the sky. Since I will be adding styrofoam sheets to the fuse and during the strengthening of the fuse, rudder and elevator, I figure I will be adding plenty of weight to the plane, so again, the 120 will work, at least I hope so.
I cut the 120 into the wood engine mount and will be mounting it inverted with the muffler facing down. I will have to do some cutting on the cowl to make sure I have enough airflow into and over the engine. The engine will be mounted on rubber washers that I found digging through the bins at Lowes. The engine has very little vibration to begin with and the rubber washers should absorb any vibration. The engine mount and front end will be reinforced with fiberglass and epoxy mixture to add strength.
The landing gear will be mounted also on rubber washers to absorbed the shock of my pathetic landings. Rubber inserts that I found at Lowes will be placed around the fuse where the landing gear go through and that area will be reinforced with fiberglass and epoxy.
Most of my day was spent hunting down parts and starting the reinforcing.
The Canopy was tinted today and small hex round top screws were used with a touch of CA to hold the canopy on. The glue on the canopy was not holding very well so I decided to secure it on for good. It actually came out looking really nice. I can post a picture of it if folks are interested.
Well Penn State won, that want really matters. More good time tomorrow.
