I am converting to BL soon but was not expecting to need to buy pinions so large to get to those ratios.
Also what mod motor were you running when you did the 5 cell race meeting? What ratio did you end up running for that BL? What was the size of that track?
Thanks,
Steve
Hi Steve,
Thanks mate, I'm glad someone is reading them
. With regards to your questions:
1. The track I ran the 10.5t motor was Brendale - Queensland (2006 Nitro Worlds and 2007 1/5th Worlds). The track is very large and open, the back straight would be approx 35meters (short version) and about 50meters (long version). Check it out
here.
2. The 5 cell test track was at Landsborough - similiar in size to Brendale (not quite the same, but we use very similiar ratios).
I used a Nosram/LRP 3.5t motor with 7.93FDR (started with 8.21FDR) (115/28 and 29)
But I have also been testing with both Peak and LRP/Nosram 3.5, 4.5 and soon to test 4.0t motors.
I will keep you posted.
