i am thinking of buying a Mini Laser and a hacker B20 15L with gearbox for it. the only problem is that it cost $200 for the motor and controler and my buget does not suport that. are there any decent brushless motors that are around $100-$120 with speed control?
Thanks for any imput.

Here are a few proven suggestions.
The MiniAC 1215/16 geared 3.75:1 with an APC 9x6 SF prop on 8-cells of 720mAh, AAA, NIMH or 800mAh, 5/4AAA NiMH. The MiniAC motor is $75 at Hobby Lobby. It fits in a $17 MP JET Speed 280 BB gearbox. The Jeti JES 18-3P controller is $84 at Hobby Lobby for a total around $182 when not on sale.
Astro geared 010 on a 3-cell Lithium pack and an APC 10x7 SF prop. The geared 010 is $150 at Tower Hobbies and it is often on sale.
Good luck!

The 010s are now available in 8 and 10 turn versions. See Bill at www.parkflyermotors.com for a 10 turn 010 and custom gearbox. On 3 lipoly cells and a 10-12" prop, it will give 20+ oz. thrust, or more, depending on your battery choice. $150 will just about cover the motor/esc/gearbox I think.

Have a look at the options from Mega in the 16/15/x range. While not quite as high spec as the Hackers they are almost half the price.

Has anyone tryed the MP Jet Brushless motors? There are 2 of them (MJ20123 MPJet AC 25/25-26 and the MJ20103 MPJet AC 25/35-20 ) from Hobby-Lobby. One of these is a 280 size and the other is a 300-400. The cost is $50 including a BB gear box. Are they junk or has Hacker been overcharging?

I have been very impressed with the quality and performance (bench tests only so far) of the MPJet 25/25-26 and 25/35-20. The mesh of pinion and spur gear is incredibly smooth (and I certainly can't say that for my MiniAC 1215 and its very expensive VMGM 6:1 planetary - it's like an egg-beater by comparison).
My 25/25-26 (standard gearing 5:1) on 8 cells 1700NiMH with a 10x7 Aeronaut gives 510g (18oz) thrust @15A (136W) and 5810rpm.
My 25/35-20 (standard gearing 4:1) on 8 cells 1700 NiMH with a 10x& Aeronaut gives 550g (19.4oz) thrust @ 13.6A (120W) and 6210rpm.
With an 11x5.5 APC E you get 626g (22.0oz) thrust @13.4A(117W) and 6150rpm.
At $50 + $70 for a controller, you are getting plenty of bang for your buck! There is apparently a Mk2 version of the 25/35 at least, with a slightly smaller gear ratio (3.8:1?). Don't know how it compares.

I can second the nomination for the MPJet 25/35/20. I have one installed on my Slow Stick and it really zips along.

Thanks! You just saved me $100. And frankly, with that money I can buy a lighter Rx to save the extra weight over the Hacker B20 15L + 4:1 that I was thinking about. Still someday I will get the Hacker (wife permitting!).
