Looks great!

Only thing that raises my eye brows is the placement of the ignition modual for the engine. I always throught that it should be kept as far away as possible to prevent RF noise with the reciever. I actually had this problem on my Super Flying King and seen other deal with it as well. Placing the ignition modual up near the firewall resloved the problem. So does the ignition modual share the same space as your radio receiver?

just a thought....

Cheers,
I didn't like it either. I moved it foreward. I have a standoff betwen the engine and the firewall. I figured a way to pack it inside the standoff. I like it better that way too.
CH claims that if you use a modern radio, 2.4 gig in my case, and and a resistor plug with a shielded metal cap, you should have no problems. I did those things. Further, do not put any radio wiring next to the ignition wiring. In a book on large scale aircraft I bought they put the throttel servo right next to the engine, I thought that was a no-no. I used about 12" of ny rod. CH mentions some guys are running the ignition modules off of the receiver power with a spare servo plug, I would not do that, they claim it works, CH does not recomend it.
