Re: Turnigy/Astro magnet article from Wikipedia

BINGO! Miles/Rhitee05, Your link led me right to what I wanted to know, do the Astros or Turnigys tolerate higher running temps. Read for yourself, info is in 1st table near the top :P http://www.mceproducts.com/knowledge-base/article/article-dtl.asp?id=32 But really, I've noted some power fade at 2...

Turnigy/Astro magnet article from Wikipedia

I've read that Turnigy RC motors use 'Neodymium' magnets while Astro 32XX motors use 'Samarium cobalt' magnets.

I don't understand much of this article. Please comment:

Re: Overvolting Turnigy motors

Mr Boots, Just made an ES seach for "Turnigy 63-74" and found very little. This thread would be so much richer if you included lots of data.

Re: Bafang bpm

The motors are sold both sensored and sensorless. My Code 13 ran 21.5mph(34kph) w/ 48V and 26" wheel. Great motor, strong and quiet. Don't know, but suspect code9 is highest Kv. I've only seen codes 13 and 14. Just be wary of buying a controller with the BFM. I've found common controllers are compat...

Re: Cuda-E - 4000 watt Shumaker drive upgrade

Yep, to set the slipper clutch watch your amps on the CA and check temp. If it slips too much the amps will fall off from not having much load, plus the clutch will run 150f or hotter. A little slipping and 100f is close. Once you're there the adjustments need to be pretty miniscule.

The Evo2 belts appear to be GT5mm with a 25mm width. I ran the Wilow Springs race with the smaller GT3mm by 15mm width with an Astro3210. Aside from the belt/pulley used, the gear ratio resulting in how much the belt wraps the drive pulley, is a prime consideration. This appears to be somewhere betw...
