View Full Version : Still looking for foamy motor recommendations!

Thanks to pinecone, I have one possible solution for a foamy profiler motor.

However, it would be nice to get some feedback on the likes of the small Hackers, Axi's (eg2208/32), Torque etc. The problem is that the adverts only say what great motors their products are, what i need is to be assured that I have an efficient lightweight motor that gives sufficient thrust (on an 8x4 or 9x4) to do the vertical stuff on a 7 oz foamy running say 600mAHr 2S packs.

So, anyone had any experience with their own 3D profiler and can recommend a good power set up?

http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXLWT1&P=7 , I used this motor with http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LX1682&P=7 on my Eflite 260 weighing right at 7 ounces using a 7.4v Thunder Power and it flew very nice. The motor is nice and quiet and runs very well. The APC props are a little fragile, but nice.

Generally the higher end motors are more efficient. So a bit more flying time for the same output.

But for a 7 ounce foamy there are scores of motors that will work.

HACKER A-20-26-M ALL THE WAY.

**I use this motor with the 20 amp hacker esc for the charger r/c foamies I fly. CR1 and Axilon 3d. They are outdoor foamies with a 34" wing span appx. Awesome flying 6mm depron. Lots of IMAC guys practice their routines with them.

I have AXI 2208/32 on my foamy's and i use it with 2s or 3s no problem great motor. The Ikarus shockflyer with this motor can easily fly outdoor but the config is a little on heavy side. The best for small foamy is the AXI 2204 or 2203.

Also Scorpion motor make a 2208 series at a lowest price and they are efficient also.

Wow! Thanks guys. Well as a main motor I have chosen something a little different.
The 'MicroDan 2505' at 32g is not too heavy but can manage 20 Oz thrust at 10A with the right prop.
However, I'm thinking of a secondary motor for either a second scratch built lightweight Depron foamy - or as the main motor for my Shocky if I really decide the MiocroDan is too heavy (32g should be ok - shouldn't it??)
So for the second motor I'm looking at the Hacker of the smaller (2204/54) Axi.
I'd rather get two, than be caught out with a less then optimum choice.
The fact is (and the reason for all my questioning) is that there are so many great looking and sounding motor adverts, but few give hard n' fast thrust/runtime/output data to enable a good comparison to be made. Plus of course even two similar spec motors will behave differently and only actual users can say what really works the best.

BTW - Mad3Deez - what do you think of this Hacker - looks light and turns a huge prop!

Something to keep in mind:

A 600mah battery will probably only produce 12 amps safely. So, 12A @ 7.2v gives you, what, 80 watts? You want about 6 watts per ounce for a 3d foamie. Don't go over 14 oz if you want good performance.

Also, ensure that your ESC and motor don't draw more than 80 watts. If so, you'll kill your batteries.

This motor:

With an 11x4.7 would fit your bill. All for about 10. Isn't the exchange rate nice?

Thanks. Well I'm aiming for about 6-7 Oz AUW, so in practice I'll be using about 40w then. With 3s packs that'l be 3-4A.
I guess I won't be using full power much - if at all.
In fact that tells me I've probably got too big a motor then - since I want the smallest and lightest that can still prop hang and pull away.
Oh well - I guess its 'suck it and see' time....................

If you are intrested in ducted fan, then www.donsrc.com (http://www.donsrc.com) has the best bang for the buck motors. The Wicked Extreme 4800kv is my personal favorite when paired with the Kong Power 2200 from Readyheli. You can even run it on 4s no problem

i second this. the hacker line is by far the best motors on the market, effecient, light, powerful, good cutomer service, and just allaround a reliable motor.

1300kv cheapy from hobbycity has been good to me. $8 and I've had them on G.P. flatouts(zero, cub and my beloved hellcat) and an eflite 260 and I'm putting one on my Enticement, with no failures and 15-20 minute flight times(at least) with 800-900 7.4 and11.1 lipo's and I use various esc's- hacker x-5, mystery 10amp, viveriene 12 amp. and use props from 8x3.8 to 9x5. the little motors are a great value to me but there is no name on them. They are just cheapies as I said.

i got e-flite 370 1300 and 1000kv?? both flyes great on 2s, or 3s.

i'm getting justgofly 2204 and 2212 to play around with..

personally i fly 2s packs swinging large prop.. 11x4 or something. 3s you need smaller prop but loose thrust, but gain speed. . go for cheap motor, unless you gonna go compete in 3d flying.. which most of us wont ;-). batteries so cheap on foamy, who cares about flight time/efficiency.. i get about 15 min on 800 mah pack. $8. go buy 4. thats 1 hr flying ;-) i normally crashed by that time.. hehe.

Hey guys, dont forget about our friends over at Innov8tive. Scorpion motors rock. I have a few for my planks. And they are reasonably priced compared to the compeditor brands. The also have a prop chart that show motor performance, thrust, current draw etc.

Except you have to keep oiling the bearings. Not sure why they can't make a motor with bearings that last like everyone else.

I agree. I love my hacker. I have a A20-20L in my one foamie. Tons of power.

Been flying shock flyers for years love them so much I have a box of 4 F3As ready to go as the airframes don't actually last to long when hit by other aircraft ;-)

My recommendation for a power system starts with an AXI2204/54 light weight at only 25g you will notice the extra weight of any other motor, especially when you shut off power.
CC10 for speedie but this doesn't really matter.
I have always run small 3S batteries of the 400mah -450mah capacity for 5 minutes of hovering. Just buy more small batteries to keep the weight down.
This power system works best with GWS 8x43 props.

Excellent hovering and punch out. Do not recommend them for out doors though, best kept in the gym.

Cheers J
