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....................
