Default radical 621P

hi,
i raced last week with my friend's radical 621P, and really liked it, but the fuel consumption was bad.
how much run time do you guys get with this engine?

I was getting 9+ mins to a tank on my 621T, not sure about the P though. I really loved my T but it broke a rod between 3 and 4 gallons.

Default 621P

I was getting 7.5-8.5 in my Losi 8. It had a 13T C.B and a Jammin JP1 pipe. I'm putting it in my backup buggy this weekend as I sold the 8. I love this mill.

6:30 to 7:30 on the older P engines. Supposedly they made some changes at the end of last year to increase the fuel economy. I think the Radical pipe helps too.

when my buddy ran a power in his 8 he was averging 9 min. a tank it kinda fizzeld a little on top end but i think that was mainly the 8 gearing. good moters but ya cant find them anywhere and distribution seems very slow
