O.S. 120 FS pumped
Hi everyone
I'm the owner of a OS120FS that I have mounted on board of a Leo F3A (China Models).
Prop is an APC 15X8.
Fuel is 15% nitro, 15% sint oil, 1% castor oil and alcohol to 100%.
Glow plug #8.
I need more power for F3A program:
I have something wrong and I can fix it or, more simply, install on board a 160 FX? ;-)
Thanks.

RE: O.S. 120 FS pumped
If the engine runs well when mounted upright, but has a lousy idle and acceleration when inverted, then your best bet is to add an on-board glow plug battery that will light the glow plug when the throttle is below 1/3 or so. The problem is that the glow plug becomes the lowest point in the fuel system when the engine's inverted, and it will tend to get some liquid fuel in it at low RPM. That will inhibit its operation. Adding a battery at low throttle eliminates the problem.
