Default Brushless combos from UnitedHobbies (Ad up on top)

This one:



What size\weight planes would they be good for? I guess the larger one, as it's only 5$ more?

Default RE: Brushless combos from UnitedHobbies (Ad up on top)

I was looking at those too. I was reading where people rated them and one guy said his plane is 2.2 pounds and it flies well. Supposedly this settup puts out 200watts. For basic aerobatic you need at least 100 watts per pound. More if you want to hover. I am ordering a combo too. My latest plane weighs 25 oz. It should work fine. Hopefully. I am getting the BM2409-12t. If you look they allso have a complete spec sheet on all there motors.

Hope this helps. Can't beat the price

I just asked this on the UH site itself. I would just like to know what recommended weights they would go up to, for the different combo's. I am looking at the airfoilz planes, as they are a bit larger than my current Hobby Lobby Foamy's, but I don'[t think my 400xt outrunners will power them well.

EDIT:

I just looked up the Airfoilz weights, and they all seem to be 16-20 oz.

The recommended motor is a hacker A20-20L:
1022Kv (RPM/V)
57g (2.01oz)
15A continuous, 19A burst
Recommended prop APC 10x4.7 or GWS 1050

Post your question on the electic motor thread. Someone over there will certainly run it through Moto Calc and give you all the specs you are looking for. The 12T is a faster motor so I do not think it would be all that good an a 3-D foamy. It will generate over 20 oz. of thrust with a 3-cell lipo and give speeds in the 50 mph range.

You say this like it's a bad thing



I may dig around for something larger now, as I am looking at an Airfoilz Yak 54 as my next plane.....

Not a bad thing at all but I think there are probably better motors out there for 3-D planes. More torque for hanging on the prop etc.

I have the 2409-12/25A esc combo on my airfoilz mobius and it works great. I'm using the 9x6 prop that came with it and it's got enough power to pull vertically out of a hover no problem. My understanding is that it runs at a lower RPM than the 2408-21's I've been using and has more torque allowing it to turn a bigger prop. It has a deeper bell to house the larger magnets and doesn't get nearly as hot as my other motors turning a 9x5 prop.

Yup, that exact combo. I'm really happy with it and the price is fantastic! Even the prop is good quality (APC type but with a small hole to fit the shaft). Works great on my Mobius with a 3 cell 1800mah li-po.

Obviously I did not know what the heck I was talking about. Souds like the 12T is a very good all around motor. Glad someone with real world experiance jumped in here.
