I realize that many factors are in play - but could I assume with that same setup that a high 10s, low 11s track would need a rollout of 80? At least as a starting point.
If I am understanding correctly a more open track can tolerate a little higher rollout and a tighter track needs a little lower. With those given lap times.
and remember I are REAL new to Brushless (never had one - but getting one)
and just looking for a reasonable method for a starting point.
If I understand correctly if I run a too high (or low??) a rollout, I can cook my motor and ESC. Just want to get in the ballpark without cooking anything.
Thanks
The carpet track I run at is 80 couple feet by 40 foot and right now I'm geared at 3.20 (inches) with an RS speedo and and trinity 17.5 brushless motor. If I did my math right, I believe thats a 77 mm rollout. It looks like I have two small spurs meshed together. As far as cooking a motor or speedo, I know that alot of speedo's on the market have thermal protection, which is like a temp switch. I believe once it cools down it will switch back on. With the the rollout I gave you and the track dimensions my motor comes off at 120 degree's and I haven't had any speedo or motor issues. Help this helps some.
