Whose gonna get one?

This is somewhat inherent in the sensorless strategy - I can assure you that the Tekin controller suffers significantly less cogging than most - particularly with a neu motor, which many other controllers will hardly run or run poorly IMO.
I have the R1Pro in the new emaxx here - only a little testing so far, but it handles the 7xl motor geared for low-mid 40mph pretty easily so far. It is too cold outside to make any real life temperature assessments, and I haven't been through all the programming settings/results yet, but so far it is a nice controller with a small footprint that works as smooth as any other sensorless controller on the market - smoother than most in fact. The current limit feature alone puts it in a class all its own as well, by allowing you to tame the low end power a bit (without current limit, the emaxx almost did a complete back flip from a rolling start - accident on my part! - with full current limit, it will wheelie over from a standstill and keeps the front end down once it is moving - still accerates like mad, though - just tames it enough to keep the front end mostly on the ground. I am excited to get more testing done on these, and the 1/8 version of this controller should be superb. Tekin is putting sensor capability on their brushless controllers at the moment - this will be beneficial for high rollout applications (4 cell on road, for example, where any sensorless system would have a similar struggle on startup), and will be the best way to run a Novak motor. I wouldn't hesitate to suggest the R1Pro for anyone looking to get one - the small footprint and high current carrying capacity (36 high quality FETS vs. 18 or 24 in many others) make this controller ideal for many applications. :)

Are you planning to stock them Mike?

Sounds real nice Mike. I was just saying what some guys who I believe were using them in races. Now, does it handle only 3S lipos? I'm asking this because when they first had the specs on them it said 6S lipos. Have you tested it with a Neu?
