Can this be used?

[kookie_guy]

Can I use this motor? Or does it have to be a 4 pole one? The part #'s with the 'B' are 4 poles, not sure on this one.

Your question is too vague. Use it? Sure you can.... You can use whatever you want.

I have the 4074 Turnigy and run 5s in my MG

[kookie_guy]

Sorry. Should have given more details.....

I'm building a dual BJ26. I will be running on 4s, and planning on using a couple of T120's, possibly T180's. Planning on using 36mm cans because I have some spare 36mm cooling jackets.

Just not sure what role the 4 poles plays, vs a motor like listed above, which I'm assuming is a 2 pole motor. There's about a $10 difference between the 2 pole and the 4 pole motors, so trying to save some money if I can. If you need any other specific details, please let me know what you need to know.

4 poles is more efficient but 2 poles work too. They should be fine for what you're doing

[kookie_guy]

thanks for the quick reply. Here's the 4 pole motor I was considering using.

Where would it be more beneficial for me to use the 4 pole ones vs the 2 pole ones? In what scenario? Sorry for the questions, just trying to get a firm understanding on the role they play. I know you said efficiancy, but there's gotta be more to it than just that.

Scroll down to the turnigy 2300kv 4 pole

I see you posted the same one. 4 poles is better. Kintec has these, and you get them in couple of days vs. weeks

[kookie_guy]

Awesome, thanks for your help. With 2 of these suckers it should fly, lol.

No prob. Yeah you might want to put wings on that thing, cause it will be ridiculous haha

I would love to put two into a mean machine hull

[kookie_guy]

I'm guessing I'm better off going with 2 of the T180's. The extra weight probably won't play much of a role, if anything it'll help keep the hull down, lol.

I just bought one of these motors turnigy 3665 2300kv for my ul1. I'm gonna use t120. Should be fine. Motor shipped today so will have soon. I run leopard 3674 1700kv on 5s2p in Titan 29 with t120 all day. No prob.

[kookie_guy]

hmmm, t120's it is then. Save me so money on the purchase and weight on the shipping. On a different topic, I've just spent the last hour reading through posts, and can't find the proper cg starting point for a cat. I swear I've seen it in the past on posts, but can't locate it now. Any idea what a good starting point is for the balance?

Just make sure to start with small props like x440's or similar.
