RE: FUNJET
The Cg should be somewhere around the org. ....but as we add cells and increase batt. size you can throw that out the window.
Just try to keep it as close as you can. The more you go foward the more up elevon you need and that = speed lost.
2500 watts man it's a wonder the wings don't melt down.
The mega 16/25/3 is a great choice and to get it to go you really go you have to start with 4cells.
You man also want to play around with cutting down props.
On the crashed/next FJ I'll run the following
E-flite 2700 kv
45 amp esc
APC 6x5.5 cut to 5.5 to 5.25 depends on motor calc and static test.
I also like het motors as they will really turn and are a little cheaper. I had one on a Stryker. The HET-4 2200 kv. With the streamline package (check my gallery) it was a sweet ride until I lost it and someone beat me to the plane.
I'll post pics today on the new ideas and see what you think.
