to run on gas

 

click on picture for bigger image

 

 

 

 

My installation of  ignition system. I have fit the ignition box in this

posision as long way from reciver to reduce risk for interference.

I fly my radio in QPCM mode (Hitec Eclipse 7) and have no problem with interference

 

 

Sparkplug purchase from http://www.morrisonandmartin.com/sparkplugs.htm 

in USA. Fit directly in engine and works well. (Enya 3 glowplug beside)

 

 

 

 

Timing point sensor fit on engine. Sensor bracket is adjutsteble

sensormagnet put into fan (with the black line)

 

 

I take apart my engine after 6 hour flying (picture) and it look good

Now i fly more than 50 hour and have take my TT70 out of my Raptor to

 look inside the engine but i have not open the engine yet.
