Thanks.
If you want best throttle performance -- ditch the 12.25x3.75 prop -- it's *way* too heavy.
Try a 12x4 Xoar or JXF wood prop -- a stunning improvement in throttle response and overall performance.
Secondly, use an OS-F glowplug. It stops the engine loading up nearly as much.
However, I'd have to say that the ASP52 is not my first-choice (or second, or third) for 3D flying.
What glow plug is better for this engine, the OS F or #7 ?? I'm using 15% nitro fuel, should I switch to lower nitro ?
Thanks.
