Just the opposite, I've found them to be quite durable compared to most.

Default 21.5 TC, VTA - v21

Anyone running 21.5 TC with v21 - how is the motor compared to v16? worth buying new motor?
Same for VTA - significant difference?

Timing for the motors?

The guys at the track that have tried it so far aren't liking it. It draws too much current and the rotor goes soft too easily. Maybe they haven't dialled in the right settings yet.

Just bought the $100 V21 17.5t motor for blinky touring class. Just want to know what is the recommended gearing to start with for medium size (25-30ft straight) asphalt track. Just for shits and giggles ... Ran it in a motor analyzer and factory settings is at 41 deg. pulling 2.8-3A 20-21K RPM

Been running a Tekin Spec-R 17.5 ....feel fast with 96/43....running a BD8.

I run on a Reedy size asphalt track 17.5T R1 V21. I've found around 410 gear ratio with 50 degrees on the can is really fast. If I were going to try running on your track, I'd start around 430 gear ratio and check temps. (I'd still keep my 50 degrees)

think our last local running a R1 finally gave it up .. after 20 guys running a 25.5 they have all bit the dust to sensor board issues (btw good and bad drivers ) .
when will motors be sold with 3 replacement sensor boards included ....better yet change the design .

Bought a brand new R1 17.5 motor... Sensors had an 8 degree swing from high to low. Tried adjusting it myself but managed to destroy the sensor board... Ok totally my fault, bought a new sensor board hoping the issue would be solved and the new one had a 9 degree swing.

20 guys with R1 25.5 going dead? Wow

We haven't seen it that severe but I've got fade issues on my 25.5 (earlier gen motor). And the fact that R1 sensor boards are complete crap QC wise.

If you're experiencing issues with a sensor board you should visit the R1 Warranty page. R1 is very good about backing their products. I have been running R1 motors for 2.5 years now and have never experienced a sensor board failure.

Same with our track lol... if a Racer here runs R1 they have 2-3 spare motors and 3-5 sensors boards. Seems wild to me this is still going on

Wierd. Lot's of people running R1 motors at my track and haven't heard anyone having an issue with the sensor board.
