What is max RPM? Im tol;d stock prop is a 16x6, however the MAS 16x6 was turning at over 10000 so i opted for the APC 16x6 which turns at 9600 for break in.
Is this correct?
I also have some issues with cowl on cowl off differences...?
I am told this is normal? Is this correct?
I am bering told to direct the carb opening to the fuse via a mod , is this necessary? I turned the carb plate around so the hole points backwards away from the prop wash but doesnt seem to have made a difference.
The engine has been in a crash but not bad at all. Was working just fine afterwards after a clean.
Should I consider cowl off flying for now?
Ignition is the standard DLE20 ignition, however I am led to believe it is the upgraded high power ignition able to handle +7v which it does say.
What has the outcome of the mod to the carb hatch been from those that have done it?
Thanks
Robert
You did not say what your cowl on cowl off issue is. If you tune the engine with the cowl off then put the cowl on and the tune changes thats normal just drill holes so you can adjust the needles with the cowl on. If with the cowl on you tune the carb and its fine on the ground then goes rich right after take off then put a tube on the carb plate and poke it through the firewall. If everything is fine on the ground but after take off and flying around the engine sags then look to over heating.
