Is 40k RPM too much for Neu?

[Thomas]

Thanks for the replies.

Edumakated, what kind of running (track size, surface etc.) did your 1509 see and how much did your buggy weigh? Were you using a Tekno Neu or an original Neu?
My 6s compared to 4s should be an advantage, though.

Now if I wanted to get a 1512 size motor, with Tekno Neu 1512 out of stock, what would you recommend? What work is required to have an original Neu work well in a buggy?

*edit*
There is quite some information about 1509 from nmt on page 548 of THE conversion thread: http://www.rctech.net/forum/electric...ml#post4605075

I'm not sure how that compares to my situation. Our tracks might be small compared to yours, very different driving profile and low traction (except some temporary grass tracks). Plus, milder weather.

Why is 100°C (210°F) a problem? If it doesn't get over 120°C, it should be fine, I thought?
