Help! Cox .020 Tee Dee Questions

Post  duke.johnson Tue Aug 11, 2015 4:30 pm

Now that I have a couple .020 TD's, I have a few questions.

1.) How much nitro are you running in your .020 TD?
2.) What prop are you running?
3.) What kind of RPM's are you getting?

Nitro at 25% or more, 4.5x2.5 prop.

I have never tached one, they turn up pretty good though. The 3 blade Pee Wee prop can be used according to the instructions.

20-23K according the the manual.

Sweet, thanks. I used 15% yesterday, I'll bump it up to 25% or 35%. Do you add head gaskets like a .049?

Yep, if needed, I have never run more than one though.
