hello
i'm pretty new to this area, i have a MINIMAG that i started with, i damaged the motor and i'm looking for a new part so ill be able to get back to the field...

i think that the best motor that will fit me will be something with
Diameter C (mm) 28~2000kv
Max Current (A) ~25-30


after my research that motor is the phisical size that i need

also i will need ESC, prop, batteries and charger (right now i have MiMa batteries that hardly hold any air time)

i will appreciate any used parts that can fit me just to save some $$

also will appreciate any tips :)

a 2830 motor with 30 oz of thrust will work very well for you. with a 9x5 EP prop. or 8x5 or 8x6 and a 25 AMP ESC with a 1300 to1500 mah 30C Lipo, Tell Jeff at Heads up Rc that Chellie sent you :) Jeff ships out fast, shipping is only $2.00 and everyone here on Wattflyers love buying from Jeff :) I choose some of the lowest prices on items that Jeff @ Heads Up Rc Had to Offer, Take care and have fun, Chellie

Propeller test data for the 2830-11 with a 3-cell Lipo battery:
It's a good idea to balance all propellers with a Propeller Balancer (http://www.headsuprc.com/servlet/the-PROPELLERS-cln-Prop-Balancer/Categories) before using them on this motor. TP propellers are available in our store, and are nearly identical in performance to APC props. Rotating propellers are dangerous. Please stay clear of prop and wear eye protection.
GWS EP9050:30 ounces of thrust at 16 amps. Excellent prop for this motor.
GWS EP9050x3 3-blade:32 ounces of thrust at 17 amps. Avoid constant wide open throttle.
GWS EP8040:23 ounces of thrust at 10.5 amps.
GWS EP8040x3 3-blade:24 ounces of thrust at 12 amps. Good choice for scale looks.
TP 8 x 4E: 24 oz thrust at 14 amps.
GWS HD8060:24 ounces of thrust at 15 amps.
TP 8 x 6: 24 oz thrust at 18 amps. Exceeds recommended maximum amps.
TP 7 x 6: 19 oz thrust at 11.5 amps.

The MM recommended powerpack is:


Himax 2815-2000 Brushless Motor
5.5 x 4.5 APC Prop, Hub and Driver
MULTIcont BL-17 ESC

This is $$$ and a poor choice chosen simply because Himax is a Multiplex brand and it's easy to put in. It's a high KV inrunner suitable for something like a Stryker. Oh, it'll work, and is better than the puny brushed motor but the plane flies better with a lower KV outrunner and larger prop. You DO have to think about how to put it in and maybe do some modifications but you end up with a more appropriate plane.

Huge thread but lots of advice-including those who go for the recommended power pack and think it's great:

I cracked mine and traced it out of aluminum stock. A bit of cutting, drilling and filing and I had a better one than the original.
