View Full Version : 2 Flights and a 50T double stripped, what in the heck??
Bobby,
Have polished the pinion, although I do not really know why, since if it is the right modulus to begin with it should not matter. Maybe the pinion spec is part of the problem, but I doubt it. If the pinion needs adjusting/polishing, then this should have been done by MA.
My Neu motor never got hotter than 150 deg F so I do not think that heat had much impact on my gear wear.
I still think that the gear problem might be due, in part, to a long can, unsupported motor. I intend to try something soon. I'm away for a week but will try this when I get back.
Cheers,
TomC
Hi Tom!
Keep us updated about your findings.
Anybody who know anything about the material these gears are made of? looks like the teeth number is melted into these secondary gears, telling me that these gears is made of a type of plastic there can melt.
Thanks!

Tom - single stage 52T on the Neu sounds interesting... I also have a 48 double that I was going to try - expect to see a bit more hs/pop.
I really want to get my Acto in the air after reading Willy's posts - I know he loves ION's - and said his Acto setup was still his FAV - figured I had to give it a try :D
Hi Guys,
Went to the field today and had problems again with the Ion and gears:
After what happened to my double 50t , I decided to try a 48t , I inspected everything carefully and found evidence that the pinion was rubbing and that it made contact with the main shaft collar after it got hot ,so I thought that it was the heat that melted the secondary and that that was the problem.
I mounted the 48t , enlarged the opening for the pinion on the plate so no contact , there's like 2mm of space between the pinion and the plate , checked the motor , pinion ,set screws , set the gear mesh properly and everyrthing was perfect.
I started the heli in Idle up with the stick in the middle as suggestted by Bobby and also flat curves, and check the results after 40 seconds.
Curious thing about this is that after I switched from the thin to the thick plate I've stripped 3 gears!! ( 2 singles and a double )and with the thin just one after a lot of flights, I'm thinking that maybe the problem is on the bottom plate , When I changed motor plates I didn't use the bottom plate and rubber cuz I was told that it was not necessary.??
I'm about to give up with the dual $$hit if somebody is interested in a Neu 1521 and thick plate let me know.

Bad/Sad news epc2,
I'm still waiting for a thicker motor mount that I ordered 4 weeks ago so I have not tried the Neu again yet. Based on your experience, maybe this is not going to help anyway?
While I feel that some support from the bottom plate should help, I suspect that the main problem is that these nice snow-white gears are just too soft. The older 56T gear that I'm currently using with a hacker motor seems to be made of much harder material. The color of this gear looks different, it's not as snow-white. I have over 50 flights on this gear and there is absolutely no wear what so ever!
Stripping gears seems to be a real issue with Neu's right now. I wish MA would try to address this problem ASAP.
I'd like to change-over my Hacker with my Neu so that I can free up the Hacker to use in a MA Razor, that I'm hopping to get for Xmas. Right now I'm pretty reluctant to do so because of this gear wear problem.
Cheers,
Tom C
I aggree! I donīt find any connection between single gears and stripped gears...double gears are stripped equal easy as single, actually the gear there last the longest with 12S wild power, was a single 60T gear.
I too think one of the problems with the gears is the material they are made of, and the fact that we donīt use the standard powertrain avaliable when the Ion-X was designed....we upgrade the powertrain, except the gearbox, that cause problems.

Sorry to hear that Ed :(. Well, this is why I put back and am still flying the Hacker motor. It is working well as it was originally designed using thin plate, bottom end ring (with grommet) and single 55t gears on 10S. It may be less powerful, but at least it works reliably... you know. With the new Extreme packs, even this motor rocks good. I'm trying to get a set soon.
My Neumotor is sitting on the side right now. I'm thinking of trying it again when I pick up a second Ion (for test rig heli). May end up going with the 32-3 motor in the end. You should try the Actros next, a lot of happy people flying those in the Ion.
Chachin..
After this , I'm 100% convinced that there's a problem with the material of the secondaries, and the worst part is that MA is doing nothing about it.

That is probably the case. They are probably made to handle the 2500 watts peak of the Hacker, but not the 3000 (or more) watts of the Neu. If MA comes out with a stronger secondary gear that can handle the loads, then I would be more than happy to put my Neu back in for hotter performance :D. But as of right now it seems to be not worth the hassle. The Actro motor without the secondary stage is the best alternative right now.

well till Chris gets the belt drive out of its testing phase and into the public , single stage is the proven setup with that much power

I agree but what makes me mad is if MA knows that there's a problem with the High power setups(Neu and high C packs) and secondaries why they keep selling them and saying that it works :badair: .
In the last month I've spent $100 worth of secondaries and thick plate and where's that $$? ,I only have the thick plate and no gears not to mention that My Ion has been grounded because of this situation.
IMO MA has to do something about this , cuz there're a lot of folks in the same boat.

I can only talk for my self, and to be fair to Chriss he told me that there from the beginning was reported problems with 12S/NEU/60T single gears.....so I knew that all this 12S testing was on own risk, and I am actually happy that I was given the chance to test the 12S/60T gears out my self.
If you have a light setup, and if you throttle down the esc. and use the power with great care, then 12S can work, but with the new batteries on the market and the present quality of the secondary gear, I simply just guess it is a better choice to go 10S right now for a two stage setup.
I think we have to remember that when the Ion-X was originally designed, we had 8000ma TP 10S batteries as the HOT choice, a LOT has happened with the batteries since then.
We are at the frontier with these big e-heliīs, we all still have something to learn, the safe choice is to take the setup the Ion-X was originally designed for, Hacker and a soft battery.

When I got My Ion last year the Neu was the recommended motor by MA. :shock:
I'm using 10s and all the gear problems have happened with 10s.

Man that is crazy Ed how did it start? i had alot of flights on both of my Neu Ions wiht n/p you know i bet the gear matereial has been changed
Did you have the softest start on?

Yeah Bobby and I followed your advice and started it in Idle up and it started very soft .

Well I had the same gear 50t doubled though, the thick plate and my double gear as mentioned in the beggining of this thread only lasted a few flights. Now I have about 13 flights on a single with little to no wear, go figure. Obviously there is a problem in the consitency of the mold or the material,,,,, "something", I changed nothing in regards to mesh or anything since putting in my single. I know that makes no sense to some of you but honestly it is all I did after my first one committed suicide like Eds did. I kinda got the must been setup or mesh talk as well. But I do want higher headspeed and want a 48 tooth "50t almost makes me sleepy", nervous to spend more dough and find out I get another double chewed up in a hurry....ugh,,,what to do... :dontknow Frustrating as I do consider myself to be master of mesh and setup on electrics as I been running high power electrics from the very beggining before this Ion.

Actually running the Neu wiht a belt drive doesnt work either as the pulleys are way to small and it stripps the teeth off the belt i did this a year ago.
@ the first of the year i did alot of 12s testing wiht belts and gears. I can tell you guys this much ithink we have found something that works on 12s

hi guys sorry to steal your thread,
but has anyone tried the new evo 20 5000mah 5S i think 5p or 4 p it is?? its the very long pack...
has anyone them yet as i am still undecided on which evo 20's to get

just what i have been tossing up over these packs look great 5000mah 5s 2p long and thin and only 100g more than the 3700s they look the goos any info boys and also im in needing of a single stage gear kit with actro 32-3 motor who sells these puppys online

I have a set of the 5s2p EVO 5000's and I get about 1 minute more than the 4350's if that. I prefer the 1p setup as the temps on everything are a good bit higher withthe 2p's.

09-21-2006, 04:43 PM
hey will,
what is the overall weight of your ion with those 5000 2p's?
i might just get a set of 3700's and a set of 5000's to use for F3c or smooth smack
I flew My Ion x today with the 32-3 and Single Stage , 100t Main gear and 10t pinion for a 10:1 Gear ratio and the only thing I can say is that I regret I didn't do that from the beggining.
Clean and simple setup and with the 100t main gear it has lots of torque.

What is the Headspeed with that setup Ed and what kind of flight times are you getting? Also do you find the HS to be consitent enough throughout the flight. I thought I remember Bobby or someone saying it didn't feel or seem as consitent power throughout the entire flight...... :roll:

Shawn ,
2050-2100 , Flight times are about the same , I remember Bobby saying that about the H/S ( Remember that the Actro is not as efficient as the Neu ), you can hear some surge in the last minute but nothing to worry about at least for my flying style it suits my needs perfect.
