Hobbystar vs. Castle Creations Motor Bench Test

[ManhattanRC]

So I've had the Sky RC motor analyzer for some time, but never used it. Yesterday I had some free time, and ran through some motors (Castle, Hobbywing, Hobbystar etc.).

Based on the results ( bench only and not under actual load) the Hobbystar (2250kv) put out the most RPM per Volt (adjusted for motor KV) than all the others. Even it's timing / phasing was well within the QA specs of the Castle 2200 and Hobbywing. The Hobbystar was noisier, but given its 1/2 the cost of the Castle I think that's reasonable.

For those out there who run Hobbystar, how does the performance under load compare to the premium brand stuff out there? Just curious as I have not run these motors in the same cars under the same conditions to do the comparison myself.

Im thinking doing a swap for my arrma kraton v2, the motor and esc are ok and the car is very fast rigth now, I was looking for a EZrun max 8 and 4274 2200kv motor, will be a notiable increase of performance?

You could pick up 10 motors from the same manufacturer and you would end up with 10 different results for KV output (rpm per volt)
Take the manufacturers kv value as a ballpark.

It’s been a little while since I’ve used a castle motor but they are definitely a step above brands like leopard and hobbystar. Only issue is you’re paying $100 for a 4074 standard sized motor, and all the $40-$70 ones on eBay are fakes that have no advantages over brands like hobbystar.

I’ll also add that it’s been years since they’ve even produced a sensorless 8th scale motor, the only one left that they still make sensorless is the 1515B (smooth can) and you can only get it by buying a sidewinder 8th. That said, because basically all their stuff is sensored, it’s even more expensive than the old genuine NEU motors used to be.

I have the same motor tester but haven't used it yet because I did not know- and did not buy a battery to run it on.
