Interesting point... not having counter rotating can't be any worse and having extremely uneven thrust from each motor... only have to deal with the problem at takeoff rather then the whole time.

I'm on my second plane, first was swapped by my LHS as the starboard motor was rotating 50% slower than port, after about 5 or 6 flights only. They swapped it for a new one without any fuss (great shop, Hobby Hobby, Streetsville).

My new one has about 8 flights on it and it's doing exactly the same thing now, starboard side, etc...... stops immediately the power is cut the port stays spinning, etc... it is not a random problem, it is a design fault with something. This second plane hasn't had a single crash or hard landing and is mint condition... very weird. Loving the plane though... it's really completes my collection... Champ for total relaxation, Mossie for scale with moderate speed and manouverability and Trojan for zipping around fast. Love the all... just hope there is a final solution to the starboard motor problem.

Has anyone here disassembled the starboard motor yet? I'm wondering if the starboard motor was designed from the start to run in a CC direction. If not, then I would suspect that this is the problem.

I say this because many of the smaller brushed motors will not last long and/or, in some cases, operate properly when they're run "backwards" due to the design of the brush/arm/wiper assembly.

I apologize if this issue has already been discussed.

toppers, interesting I got mine from toys for big boys, i wonder if this is product wide or confined to a particular batch of planes

as for my idea to reverse the motor, um, you would have to also get a left side prop heh - that part slipped my mind - would of been funny watching the plane do donuts though.

Well I will call horizon today and see whats up with replacing mine

Thanks, that answers my question. Kinda stupid of me not to realize that Horizon wouldn't run these starboard motors "backwards".

Agreed
Which makes no sense......and if that is the case then it is a quality control issue with a particular production lot....and someone in China should be paying more attention!
We have been making clockwise and counter clockwise turning motors since the invention of electric motors. A counter clockwise turning motor does not defy some rule of the Universe.

I am back to the theory that the 3rd shift spilled their Tsing Tao beer on the goods! Does anyone's right motor smell like beer?

well i gotta say horizon took care of me again in record time, called and left my number for call back, 15 mins later i was on the horn with someone and they are shipping a new pair of motors out to me today! I will try to be optimistic but I am guessing these replacements are gonna last about the same time as the originals

+1 for horizon service
- 1 for beer soaked motors

It's interesting you mention that, regarding the right motor stopping when power's cut while the left motor continues to spin. Mine's still flying fine, etc., but I noticed this last night after replacing the left prop shaft--the right stops immediately when I cut power but the left keeps spinning. That's the only difference I've seen between the two motors, so far . . .

that's what mine did before it just seized up for the most part - now the motors will cut after 1-2 second throttle.

trust,


Big +1 on HH cus service!
The call back feature is great.



Hopefully you have seen this thread:

The Nine Eagles motors are proving to be much higher quality.
Reverse rotation is still a problem.

These brushed UM planes have been on the market since July 09.
Seems like Horizon should have found a higher quality motor source by nw.

Hindsight is perfect, but they should have used the same motor running the same way but facing the rear and driving a gear placed on the rear of the shaft.

Gearbox and prop shaft would have been a bit longer, but I think the weight diff would have been small enough to ignore or compensate for.

Is the effect from 2 props turning the same way so great it really needs a reversed prop?
Someone's got to be at the point they are going to swap in an normal motor and prop/propshaft for the right one.

Thanks for the info RCB.

I happen to have a Nine Eagles "Sky Eagle" that has held up well so far (@ ~ 12 full battery cycles).

BTW, my HH Blade CP helicopter has well over 250 full battery flights on it and the only things I've had to replace so far has been 1 main motor, 3 tail motors, the battery (@~220 cycles) and one set of main blades.

yeah i have seen that thread, havent had to order any NE motors as of yet though...well until now i guess.

Wouldn't the motors from the NE coax work for this application? or are you saying those suffer the same problem with the reverse rotation?

baaaah - i just want to fly... hey isn't that on the box? "just fly?"
