I was looking at the CH horns... they don't look like enough for 3D throws... they are nice though. I used the Rocket city horns and mine are nearly 1.5 tall to get the right displacement (45%).. I don't see the hyde horns getting anywhere close to that. The pics above show about 30% max..


As far as locating the equipment.. mine is all jammed into the nose on the firewall. The ignition, Li-Ion battery and regulator are all touching, the RX battery pack is 4" away from the Ign "bundle" and the throttle servo is mounted on the firewall 1" from the carb. The RX (PCMR770 JR) is less than 6" from all the rest of the stuff.

I went to a smaller (18oz) tank, elevated the tank and moved the Pull-Pull setup under it, so now that pull pull is as far forward as it can get and the tank is still nearly on CG.

I have perfect range and no issues in flight. My CG is 5.00 inches and my weight is 16 pounds 5 oz WET.
