AE B4.2 motor recommendation, tight track indoor clay damp to semi-dusty.
Track is tight and small. Trying to figure out best motor/ gear setup for it. Track owner recommends a 17 turn sensored motor. Any imput on these conditions.

Not so interested in brand but more about the amount of turns. Is a 17.5 quick enough for this track, I was thinking more like a 13.5 or less. But Mabee it's more about gearing which I'm still learning. Someone with more experience possibly can educate me a bit.

Reedy 17.5 Mach 2. Fantastic acceleration and it is probably the fastest 17.5 motor out there.

If it is small and tight, a 13.5 or anything lower may be over kill. My track is an medium traction medium sized indoor and I run 69/33 with almost max timing on my 17.5 and it comes off at 145-150. It has a pretty descent speed down the straight. If there are jumps that you cant make in your "small track" go down to a lower turn.

I got a question on the Reedy Sonic 2 motors timing marks. It came with 20* timing from the factory. Which line would be the 24* timing?

Definitley go with a 13.5 imo. But check what everyone else runs locally. Most tracks only have 13.5 or mod buggy races. Unless youre one of the best drivers anything more will be overkill and you will be surprised at how fast a 13.5 will be. Only downfall is if its also a backyard/parking lot basher too its not as fun doing less than 60mph Go watch some races at your local track or on youtube and get an idea for speed/size comparison. Check out island raceway 13.5 buggy A main on youtube.

We used to run 24 degree on 27 turn brushed stock motors but on the brushless you can run any can timing you want. On my 17.5 I have it cranked to the max for blinky.

From the sounds of your post it sounds like your newer to racing. I would go with a 17.5 turn for sure. You can always boost it more if its not a blinky class as you get better with it. I have mine geared 34/69 for a larger track, and when I go to our small indoor I drop to a 33/69. Both in blinky mode. Plenty of speed for me and I have been racing for years.

17.5 as recommended by the track.. IF they have a stock class AND you want to race. Otherwise a 13.5 would be a great choice. Not too much power to control yet enough to be fast. 10.5 or lower.... it will be fast and fun but you will crash more and probably slower lap times as well.

are you including the timing gain from sticking an allen wrench in the motor and twisting the shaft ? shhh. and whatever you do , don't get a massive set of pliers to bend the can in closer to the magnet. Dieter?.. what are you doing over there ?

I run on a small indoor track also. I use a 17.5 and my lap times are about 19-20 seconds. With a 7.5 times are like 18-19. Not much of a difference. The 17.5 is definitely easier to control also. You can really get on the throttle a lot without it wanting to spin out with a 17.5.

Yes. New to racing. Been running a stock sc10 in novice and want to step up to 2wd buggy. I actually try to take it easy on the throttle and keep it on the track instead of hammering it into the wall but I like that quick burst of power and just want to do it right the first time. Seems like the 17.5 is plenty for my skill level but 17.5 and the 13.5 are the same price. Unless it changes the class I race in I think 13.5 and just have some throttle control.

Really good advice on here so far, much appreciated !

13.5 will alter what class you can run in if your track offers stock and mod/open. 17.5 is stock and anything above that is typically open/mod. Tracks will not let you run a 13.5 or faster in a stock class.

The nice thing about 17.5 is you can run that in any class (stock or mod). Like said above, stock times are very close to mod times at most indoor tracks.
