Great kit, one of the nicest around for finish and price!

My current one runs an HET6904 fan and Typhoon 3W motor. Very efficent power setup, 35 amps on 4s2000 30c packs, handles superbly after spending time setting up mixing and control throws. Video is here: http://www.rcgroups.com/forums/showthread.php?t=783084

I agree with the others, buy the kit and use the factory power system, its a great package for the money. Cheater holes are needed if you are running the stock inlet as it chokes otherwise. Problem with the cheaters however is the pressure differential they create under the wing, causes the plane to be pulled down under power. If you trim it for WOT then soon as you cut the power it will climb like crazy.

Easiest way to fix this is mixing throttle to elevator. I found I needed around 9% up elevator with the first half of the throttle travel and 2% up with the second half of the throttle travel (mixing gives you the ability to adjust + or -% for both sides of your stick throw, the throttle is treated the same as any other stick movement with centre being neutral).

Now when I cut the throttle back the nose drops a little, still needs some fine tuning on the static trim and mixing trim, but its soooo much better than the stock ballooning!

You must reinforce the rear end, I started using 0.4 and 0.8mm ply sheet to box in the rear pylons, remove the brass sleeve and plastic sheet, then sheet the side and bottom with lite ply, refit the brass insert, all with epoxy, and the rear end will be super strong.
