C5 Rody head shimming for 30%
 
Does anybody know if the C5 Rody is already shimmed for 30% nitro? I heard from one person that it is but the rbproducts FAQ says their 21's are shimmed for up to 25% nitro.

Thanks,
Kel

Anyone remember the RB C3? How was its power and performance? I was offered it at my LHS for my Top engine and I'm wondering if it will increase or weaken performance. The only way to know though is to run the top on 30% as is and compare in the future I guess. :nod:
The C3 is a weapon, I still have a C3 Rody Worlds engine. It is still a good engine, it now does service in a 1/8 buggy.

Rody has always stated that the RB's are shimed for 25% from the factory. Some run them this way with 30% and have no ill effects. Most add the shim!

C5 Rody Modified Engine problems
 
I have a relatively new C5 Rody Modified Engine and while running in a 40 minute race this past weekend the engine decided to suht down and run REAL bad. Engine temps were kept in the 200 - 210 degree range.

Upon inspection - the piston has broken apart near the skirt.

Can I just order the piston since the engine still has tons of pinch? Where to I send the engine to get repaired ?

Is this a common problem?

Thanks in advance!

Contact the Hobby Shop you purchased it from - they should be able to do the repair. If they aren't helpful - contact Kevin @ Ace (650-632-4057), he'll fix you right up. I would get a piston and sleeve set - kinda risky just getting a piston. This isn't a common problem - sucks that it happened.
