Default TeeDee .090

Hello Guys,
I am also playing with a .090 at the moment. I was disassembling it and I destroyed the phenolic washer behind the prop hub. I couldn't find a replacement on the cox engines site. Where can I get a replacement washer from?
Much TIA
Rick

Might be able to make the above phenolic thrust washers to work if not there are steel ones bellow.

Thanks,
I ordered the metal one, it looks sintered. I'll give it a try and see how it works! I also ordered a rod resetting tool, I'm going to tune this one up and put it up against my .049. Thanks!

Sure here are the power charts the .09 is a bit more than twice the watts.
Good for a 2lb airplane. Better for a 14 to 24oz plane real rocket.


On a side note my TD .049 / SPI with exhuast throttle, exceeds the power chart:
High compression head 1 shim.
4.1 x 4.1N / 30% nitro
Static 24,790 rpm / 7.4oz thrust / .127hp / 94.74w / 96.2 mph
Modern prop modified for performance helps to change
old school info as I was only using 5% more nitro. + 15.74w

Real good odds of getting over 20w increase with a .09 and modern
performance props.
