iam from egypt and i need micro motor make 7 doller and i wont buy this is money i gave to take this motor and i wont much things but i wont price i gave to buy and money to charg
All but the smallest 1S LiPos should be fine. Like something in the 150mah and higher capacity. Of course if you like to over-prop your motors then a higher C-rating is recommended. I am using this gearbox/motor with a GWS6050 SF prop cut down to 5-3/8 inches, a 320mah LiPo, in a Multiplex Fox glider. Flys at 45-50pcnt throttle. I did change the prop shaft bushings to ball bearings so remove slop from a warn bushing.
petedee,if you use it with micro planes such as p51 or micro j3 cub a 130mah or 160mah nanotech would give a best result i use this for my micro j3..

Of three units I have, one has a rough spot or two as the a gearbox turns (just the moulding of the gear). The other two gearboxes are loose and smooth with a slight rattle from the retaining ring and/or bearings. I’m guessing the stiff gearbox will loosen up with a bit of running. Weighed in at 6.9g.
The gear ratio is 17:3 (5.6:1). The motor measures in at 8.54mm x 20mm, so a slightly larger diameter to the solopro motor (8.44mm). It is a very (very) tight fit in the gearbox – don’t expect to remove it without pliers. As best as could be measured, the motor shaft is 0.95mm diameter. The plastic prop shaft is 3mm as stated in the description (at the reduced section) and is thus loose fit on a GWS 5x3 or similar prop (unlike the 7mm gearbox), though the GWS propos could be drilled out to fit the 5mm diameter at teh rear of the prop shaft. The metal shaft beneath it all is 1.45mm which allows a tight push fit on the parkzone props.
There are two mounting holes for a 2.9mm diameter rod/tube (north and south of the prop shaft) and four small screw mounting holes (east and west), so plenty of options for attaching to your airframe.
Some crude test data (I dont have a set up for measuring thrust) compares this motor favourably to others on the market.
Motor gets warm after a 30 second run at 3.6v, but not hot.

Got two of these. Both works fine. The weak point is wires - very thin and pretty fragile if you didn't fix motor a the place. A wire of one of my motors was broken right at the base (of motor). This fact gave me some unpleasant soldering experience.
So i change wires with a half of Mini Plug Extention for Micro Battery 10cm on both motors and secure connections with some glue.
Also lubricate the bushings with moly grease. Seems works fine.
Here's some inaccurate and probably incorrect thrust data:
Voltage 4.0-4.2
GWS 40x25 — 23-26 grams
GWS 50x30 — 40-45 grams
GWS 60x30 — 45-50 grams
GWS 2*50x30 — 45-50 grams
2*50x30 is two coaxial 50x30. I have plans to make one four-blade prop of two of those. It seems pretty easy just needs some hub filing and gluing together on a straight axis, but the data is just for two props one by one on a motor.

Used this drive to build a micro IFO (approx. 300mm span) with a DSM2 micro board (spare part of a parkzone Vapor) on 1 single 110mAh Lipo.
Drive works fine, and is far less noisy than a Minium Cessna , although not quite reaching the qualities of the original Vapor gear set

When testing this drive shaft welded itself on brass bushings. I then cleaned and regreased it and it runs perfect now. 1s 160mah with 5x3 prop gives very little thrust. I tried putting two props and was better, but too heavy. I then trimmed heli prop so it fits. Hard to say which prop is good for this setup, but 5x3 definately isnt`t good enugh.
I am using this motor on a hk-190 5in1 board and the board is reseting a lot of times when applying throttle. Probably ohm rating on this motor isn`t the same. I also get a lot of servo jitter because of electric "noise". It works, but is a little annoying.

I had this motor for a whole season now and I am finally ready to write my review. this gearbox is almost the perfect replacement for those Parkzone UMX planes. the only difference is the gear is larger but you get more power. With a 5x3 prop, I was able to get over 50g of thrust. These work perfectly with any DSM2 brick. Only 2 downsides, one of the c ring on the back of the shaft came loose (and i lost it). I replaced the shaft with the same shaft from the UMX gearbox (almost a perfect fit). the other was one of the gears was slightly mishapen from the moulding process, easly fix with a few carving strokes with my hobby knife. I love these!
