My son bought a b4.1 ft recently & we finally got it to the track today. I was extremely impressed! W/ an mmp w/ no timing & sp 17.5t it was fantastic. We just had a base set up for a clay track & stock springs. Once he gets some springs to adjust the set up, I see this thing being a great buggy. It had a little push coming out of tight corners on power, but I can see it has tons of potential. The motor was a little down on power to make the big jump on the track, but only by about 6". A little timing advance & tuning to get the front to stick a little better & I see his b4.1 doing great things! My biggest problem with the buggy is I want one now!

Try it. Take two springs attach them on top of each other and put a controlled amount of weight on them and measure how far the weight falls. Now take each spring individually and do the same thing. guarantied you will see a higher spring rate with the individual springs. if you don't want to do that go to college and get a mechanical engineering degree, as many on this board have done.

Lot of it depends on if you are running a non timming class or not. Our track went to a stock no time class. I have run a 72 spur or a 69 spur. With the 72 spur i run a 32 pinion, and the car handles well. With the 69 I used a 34 spur. Both gear combos worked about the same. I run Tekin esc and motor. The motor timming is set all the way up. I have heard the novak motor has more timming. Most guys run the 72 spur at the track here 31 or 32 pinion. I think you will be happy with a 72/31 combo. Throw a temp gun on it and see where you are at after your run.

I would highly recommend this motor! I know a lot of guys in you area are either running orion or Tekin but definitly give the Sonic motor a go, you won't be dissapointed!

I love the Reedy Sonic. I own the RevTech, Viper, Speed Passion, and LRP X12, all in 17.5's. I prefer either the Reedy or RevTech motors. The reedy has a little more torque then the RevTech in my opinion. I try to run them as cool as possible just for the simple fact I don't want to replace them. The motor would come off after a 6 minute heat at 110-120 geared at 33/75... My timing on the can is set two marks past 0 and I am running Blinky on the ESC...

Just a thought. Has anyone thought of using tubes instead of foams? I know you couldn't find any that size but maybe a company has tried them and they haven't work out? They would never wear out like foams and you can adjust the firmness of the tire without having to take the tire off and putting different foams in.
