Thought I would share my new Road Runner .21 Extreme. Gonna try and run it this afternoon.

 
Matt,

I heard you needed more propeller for that RR-21?

I will put some options in the mail from my box.

Looks Nice,

Mark
 
Finally got some video of the boat running. Not quite where I want it but its getting there.



Let me know what ya think.

Great run boat had a lot more it's running a little wet put a shim on the turn fin side front sponson it would help a lot.

Looks awesome

Julian,

I already have it shimmed quite a bit in the front. I was trying out an OPS 3280 I need to switch back to the Cooper-Wood S Pipe. I havent found that special prop yet. Always a work in progress.

Anthony,

Not a stock 5 port by no means but not much different than how the 5 ports do run.

what changes are you making? I read about the carb,.. I do just the head volume and carb on mine.. runs very well actually.. What else is working for you?
