thanx for all the advice guys!went and buy myself 15% heli fuel today and a 11*6 APC.while tuning the engine again I could feel it has more power,especially if I held it vertical!it always just rest lightly in my hands, but now it wants to go up!just have three more questions;
1.I did tune the high speed needle valve,must i tune the low speed as well?(from idle to full throttle was just as good as always,no hesitation or blubbering, it just ran!)
2. is 15% heli fuel fine?(the shop doesn't have any 15% airplane fuel, but the ingredients and stuff are precisely the same.)
3.after i was done and the engine cooled off, i'm always in the habit of swinging the prop with my hand to feel the compression, it made less than the usual nice "thud" sound almost as if the compression is a bit less.is that possible or just my imagination?must I worry about it?
