HK Piper Cub L-4 version

Originally posted by Dutko Can somebuddy help me for the size of the pilot? I saw the pilot of HK with a length of 11,5 cm. It is the same pilot of the l-4 of KMP(is the same as CMP). Will this fit or is this one too small? Thanks for your help! Theo

He is perfect. I have that exact pilot in my Grasshopper.

Thanks Snappy and Crashtruk. I think i buy two of them to put the second one
with his back to the pilot. I will build a radio in front of him.

Originally posted by Crashtruk Anybody know what covering to use to patch a hole in the wing (top) Punched it when I was drilling the holes for the stuts,

Why don't you guys put an adjusting collar over your drill, before you start this work ? This will prevent you from punching the wing.
You can also put a nice decal over the hole in the covering...

Finally maidened mine today. A little to windy but I went ahead anyway and managed to land in a gusty cross wind without damage.

The RCGF 20 cc was set way to rich on the low end from the factory and we struggled for a couple of afternoons to get it to start and run right. Once it was set right the engine came to life and flys the plane well. Using those MG orange servo's which seem to center good and work just fine on this plane. Using a Zippy 2500 2s LiFe pack for the Rx and ignition. Have an ignition kill switch and a diode voltage reducer going to the ignition.

Hope to show it off at the clubs funfly on Sunday

I have almost the same configuration. Only difference is that I use a 2S1P LiFePO4 battery for my Optima 9 RX and for HK 15288A servos. My voltage is also reduced via a Schottky diode (MBR 1645). I always operate with a separate ignition battery which is in my case a 4 cell NiMh battery with 1800mAh. My Grasshopper has full telemetry installed. (GPS, engine temp, RX temp, seperate alitmeter HowHigh with +- 1 ft resolution and RPM)
I was a little concerned about the engine temperature because of the little openings in the cowl of the Grasshopper L4, but as measurements showed, everything is ok. (Engine temperature is always below 120°C or 250 F) The only thing which was replaced was the muffler of the RCGF-20 which was replaced by a Pitt's style muffler. (so no openings in the cowl!) Btw. I had the RCGF-20 on my test bench for the first half gallon and did the proper adjustments there.
So I can reccommend this configuration!

After some time the wires at the horizontal stabilizer bacame loose. I just put some rod stainers in between.
