Guys,
If you're building a 4* you may want to check out my web site on 4* Mods. I built one earlier this year and did quite a few mods to it that you may be interested in (cockpit/canopy, nose cowl, turtledeck, etc.)
I've had tons of response to the site so it seems to be helping other 4* builders out a lot. Good luck on your planes, the 4* is a sweet bird that will fly very stable but have respectable capabilities. I chose to use the 40LA on mine (first low-wing tail-dragger... not a 3D plane) but grew out of that engine quickly. The 46FX would be a better motor on that plane. Still, it's a ball to fly even with the 40.
Good luck, you're gonna love this plane and it's a well produced kit to boot.
