Guys

I'm covering the first of the lightened wood Curares now. We'll see what kind of difference the weight makes. I do know that at 8 lbs, the one I'm flying is an absolute rock in the wind. It just stays where I put it (whether it's right or not, unfortunately).

The bigger prop on the 4s helps the downlines a lot.

The firewall needs to go back a little over an inch to mount a 4s in a fiberglass fuse. The engine will fit nicely mounted inverted. A remote glow driver helps a bunch if you're doing tricycle gear.

To build wood fuses, I've had to widen the firewall and the two formers. When using 1/4" sides, I had to widen 1/2". By using 1/8" sides, I saved a quarter. If I hung the engine on sideways, it would fit the original width, but would leave a huge lump hanging off the side. I like the looks of the inverted mount for the 4s.
