Hey Guys,
I’m having some problems with my Hifei ESC functionality and data logging. First, I have two brand new 240 pro + units going into a twin. On the first test run I noticed that that data logged never reported more than 75% throttle on either unit. Both calibrated successfully, per the procedure.
Also, the RPM’s don’t match up with what I’d expect after some extensive trouble shooting and bench testing. I’m starting out with a 4 pole 1730KV on 6s. On the bench, this should spool up to ~ 38kRPM, right?. My data logging is reporting 20k RPM. On the bench, I’mtesting the ECS/Motor combos separately and getting repeatable results…No 100% throttle, and low RPM (and yup, I’m inputting 4 poles prior to uploading the data)
I’m using a Spectrum DX3C and MR 200 TX/RX, which I’ve neverhad issues with. I’ve re-set all the settings on the TX (no expo, everything trimmed to 0, etc), re-bound five timesor so, I have plenty of supply voltage to my RX, my lipo’s check out ok, I’ve recalibrated both ECS’s multiple times…which has never given me an issue, I’ve tried different receivers (had a brand new SR300 available) and different transmitters…all yielding the same results. ; (
I am able to crank up the throttle travel to 125%, as some have suggested after calibration and this will let me log that I’ve actually hit 100% throttle input; unfortunately, the RPM’s are still low per my calculations.
I've never had issues with these components before and am wondering if I’m just missing something super basic…or if in fact the ESC’s may have issues.
Any help would be greatly appreciated.
Thanks!
