Remember those $.60 mini motors like the stock HB tail motor?

There was a thread where we were wondering if you could use those micro motors from the electronics suppliers. These mini's. well I just burned the 7.2 so I final tried on of the 8 I bought. ITS BETTER THAN THE 7.2 AND IM USING AN 8 TOOTH PINION! but it gets hot fast. good thing heli-world has those pretty heat sinks for the main and tail motors now. I also fid that the HB mixer has power distribution issues with the 7.2. it seemed to slow at higher thro. this one spins the heli clockwise nicely

Have you tried them? I hovered this one till the battery went dead. I will have to track its life and let you know. I tried a $8 esd50 and it seized after 3 uses. A stock HB motor cost $12and it burned pretty fast to. thats about 16 of these.

Airchopper,

If those are the wrong ones, can you post a link to the right ones? I [we] would much appreciate it.

Thanks -

The problem with those is that they are rated 1.5 to3V which is a bit low. If you were to change the pinion to a really tiny one, then perhaps they would last a bit, but they really are not expected to last very long. There is a higher voltage version which works, but is more expensive - the wattage B2C motors are the proper voltage rated ones.

Some have used two of the lower voltage motors in series and they seem to last, but you gain the extra weight.

somone post a report after a couple of flights, i'm interested in using these on my piccolo... as far as the rating, I've seen quite a few RC motors that are rated from the OEM in the 1.5 to 3v range, RC applications just push the motor much harder. (and doesn't expect much lifetime either...) This size motor was probably originally used in buzzers on cell phones and pagers.

I think the stock HB/Piccolo motor is 7.2v. I wouldn't bother risking my already prone to crash micro

I will but I want to get or make a heat sink for it. I dont remember how many flight I got out of the original motor. I just remember complaining that it went bad so fast.

So if I can get a couple of flights out of these with better performance and no wieght or power issues and get 15 for the price of 1 will use these. thats 30 or 40 flight for the same price. I know I didnt get 30 flights out of any of the other motors.

I believe the stock motor is rated at around 6V. Like is mentioned, e-flight is typically about using these motors above their ratings. However the tail just needs to counter torque a bit. I woudl think the LB would work if geared properly.

FWIW - I have not logged the number of flights but I estimate well in excess of 100 on my B2C motor, but I think it may be going as it is acting up a bit. Funny though, as soon as I installed the hornet blades, my tail motors seemed to run cooler. It may just be my imagination though.

100! WOW! I think since the Hornet blades have less pitch and faster rotation the tail would not have to work as hard to counter. I have to get this B2 motor. Who has it?

Its CP. and also has less pitch so the tail also does not have to work has hard. It have to almost set my Hornets tail trim max right when it was FP. With CP I didnt have to adjust it half as much.

Do this, decrease the thro curves and increase the pitch curves and then set the tail up, and let us know how many more flights you get

50feet -

I've seen the B2C motors on http://www.balsapr.com site, but I think Nippon Dave's are cheaper - should be the same motor from what I can tell anyway. The 3 different b2c motors on the balsapr site must have different pinions attached, hence the $11.00 price (vs $6.xx no caps, no pinions, no leads from aircraft-world).

Here's a link to aircraft-world - just know that I haven't tried one of these myself yet..

but it will be the next one I get when my current tail dies.
