Ok, Thanks guys, I will check that post a bit later. I am at work right now and last night and this morning I didnt have the time (and the strength) to take my airplane down to reset the throttle geometry. Right now my DLE20 is running as it came out of the box.

I havent even touched the needles. My ears are not good enough to note the difference in the sound in doing this, so I had one of the more experienced club fliers set the engine up and he and a few others were ok with the needle positions. So I am not sure how to set the ignition timing etc. It doesnt hesitate, cut etc so I should be close to ok. May be you guys can enlighten me / point me to the thread / post where the procedure is given.

The way I set up the throttle is I held the carb arm physically at approx middle of its motion range and then adjusted the stud servoside at neutral to get the position. I had seen Jedijody's geometry post but I am still not sure how you can measure the angles accurately. Should I get out a small protractor from a shool geometry box and check it?

Regarding the 9C, I bought it second hand couple of years ago. (Now I think I know why that guy wanted to sell it). It was fairly cheap (about $150) for the TX. It came with a 72MHZ module and I put in a 2.4ghz module. Otherwise its a full featured TX and I wouldnt want to give it up because I am familiar with it and because I have spent a bit on it. May be I should fly glow with it and port my gas models to the 8FG. In this case, should I replicate my trims one by one to the 8FG as they are from the 9C? Also, are there any user guides to using the 8FG in video or so? I wish someone would 'teach' me to use it atleast to the point that I understand what to press at which time and I am sure I am not doing anything wrong
