Hi Everyone.

I have a DLE20 using a CRM-6 plug which has had about 15 flights so still new. Ive had no problems with the engine whatsoever, being new to gas this is my first and I am/was liking it a lot.
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
