How to wreck your tail motor by adding a pinion (PLS HELP!!!!!!!)

Ok....well, I got the dual tail setup right, and the gears are noisy (coz they suck)

So, I ordered some stock tail pinions to replace them, which is supposed to be much better.

However....on these tail motors (like90 - allelectonics?) the shaft does'nt go thru to the other side of the motor, so when you push the pinion on theres nothing to push against, thus wrecking the motor...yay...

Well,

1) How the shiznits do you put on the pinion without wreckin the motor?!
2) Gimme a link to these tail motors from allerc pls I dunno which... Thanx!

I usually push on both ends of the shaft so no pressure is put on the motor...but you can't do that if theres just plastic on the other side....

Hmmm, when I put the pinions on they only needed very little pressure, just slid on really easily. I put a bit of glue on and no problems.

I have rewritten this a dozen times attempting to make it not sound so funny, but I've given up. I can't help how it sounds. Have you tried lubricating the shaft before putting the pinion on?

Either that or I have larger pinions.

Damn the 1970's British comedy I was force fed during my tender years.

Getting back to the subject, honestly they just went on with finger pressure. I didnt use any tool at all.

smste2, I run Like90's dual tail motors on my HB FP Elite and they work fine. I did have to very slightly elongate my mounting holes, but Colin and others did'nt so I'll write that off as slight mfg tolerances on my stock tail mount. Note, this was only about 1/32". The gears mesh perfectly. In my case, I'm running seperates with the Like90 blades, a GY240, and the dual motors made a major difference in authority compared to stock.

well..i can also confirm that the like90 dual tail pinions to not match the dragonfly spur gear.

I removed the pinions and put on the stock dragonfly ones. one went on easy, and one did not fit for a strange reason (too loose)...then when i tried to put back the like90 one, I ruined the motor somehow.

I think i can get it working by using just the stock dragonfly motor and resoldering the connections.

I still have faith it will work, and work well, but for a dragonfly, it's not a drop in upgrade.

OzzieFlyer, I have no experience with the Dragonfly but there is a difference between the HB vii and the HB Elite series. Hopefully Colin will jump in with some insight. I know he metioned the Duals were designed for the HB and the Elite. I wonder if the DF used a different motor and/or pinion and/or the tail gear is different?

Some of the Like90 pinions were manufactured to the wrong specification. All the ones they are selling now have the correct tooth form to match the plastic gears on the micro helicopters. The shaft hole is a very light press or slip fit on the motors so you wont damage the motor when fitting the gear, but the gear will have to be fixed to the shaft with Loctite (609,640,680) or CA. If you are having a problem, contact them and I think they will take care of it.

This is the reason we use glue on pinions with the tail motors we supply. A dab of loctite 680, and the pinion will be on and super secure, with no possibility of camaging the motor.
Our pinion manufacturer caught a small deviation in the size of our pinions, and has corrected the situation. Contact us through the like90 website online form if you have received pinions that dont mesh well.
The tail motor bracket for the Elite is different than the standard tail bracket in a couple of ways. It is angled to allow the use of the stock tail rotor blade protector stick thingy. (sorry for using such technical industry jargon) As well, the diameter of the mounting location (the part that glues on to the stock plastic tail motor mount) is ever so slightly larger than the standard mount. So definitely use the Elite bracket for the Elite series heli, and the standard bracket for all others.
One more thing. With the large number of different micro heli's on the market, it is next to impossible to have a single product that is a perfect match for each heli.
Some of the tail gears stand farther off the bearings than others do (The Aerohawk for example) In this case, about all we can do is to suggest that you slightly sand down the standoff on the tail gear until you get proper alignment.
