After the BP21 (2408-21) a year or so later the 2409-12T came out and was very popular among Stryker owners. It provided really good speed and unlimited vertical with plenty of torque. I ran an 8x6 APC E prop on this motor. This is over propping it and drew about 30 amps. I would not suggest running anything bigger than an 8x6 because that’s already red lining the motor. I think anything bigger will push it over the edge.
NOTE: The 2409-12D is a better design (not a bell style) and, even though the specs are the same, it can handle more amps due to it’s build. I would suggest anybody considering this motor to go ahead and opt for the D version since it’s only a few dollars more. I’ve also read of people running I think 8x7 props or bigger on the D without overheating it. The more solid construction helps bleed off any heat better.

This motor is excellant value for the price. 200 watts for less than $10! I fly this motor on my F-27 Stryker and it has been radar gunned at 82mph. I use a BM2409 motor, 7x6 APC prop, 35Amp speed control and United hobbies 3S1P 2200mah 20C Lipoly battery. 190 watts in a 20oz plane. That is about 140 watts per pound! The short, thick shaft takes a beating and has not bent yet! Mine has 100+ of flights on it . I now own 4 of them and my flying buddies have a bunch too! Put this motor in any 16-30oz plane for great power to weight performance. I know a group of flyers who are racing GWS Formosa's with these and are rippng up the sky. Great motor. Great price. No problems.
I use this motor in my F27C Stryker and with a 3-cell LiPo battery, it flies fantastic! Unlimited vertical.
I used the stock motor mount with a 2-liter soda bottle cap to mount the motor. What a great motor.
The motor does get warm after flights, but only really hot on warm days.
I use a 7x5 prop with this motor. Just great
put this on my stryker b model took the base off and epoxied it to the stryker mount then put motor back in the base and it lined up nicely.ran a 7x4 apc prop the plane launched nicely and went vertical easily.straight speed guess is maybe 50-60
Got this one as combo, very good deal and this CD-ROM motor performs better than many others. I put it on static thrust test. Look for yourself on these data.

This motor is great. 3s 9x5 gets hot. 2s gave me the better results on 8x5. Pleanty of thrust and 7 min of flight time for 1100Mh 2s. Reduced throtle to 60% and I get 11 minutes.
Hi,
I take this motor for the UH (HC now) P40 results with power analyser :
with UH 8*6 APC Style :
22A 280W 11.1V 1700 10/15C
28.5A 325W 11.1V 2200 20/30C
With UH 9*6 APC style:
29.2A 300W 11.1V 1700 10/15C
Don't make with the 2200 20/30C for don't burn the motor !
I give on the 1700 10/15C 11.1V with the 8*6.
Very good motor with very hight thrust !!!!
Installed on a 100% 25oz AUW Super Bandit. Gives 30oz thrust with 7x5 APC drawing 20A/220W on a 3S2100 15C. Cut a groove or ride a fast rail with this one.
Great little motor for the price. It handles loads upto about 30A (full throttle at 3S using a 8x6 prop) without overheating. There 9x6 is too much so don't try!
I use 2 of these on my twinstar and they give near vertical performance. Topspeed is around 130km/h in this configuration
