Turns out I'm now convinced that the one way bearing is at fault. It melted another one this morning, so I think the bearing is getting too hot, it probably had no grease left in it, and would slip a bit, causing it to heat up and melt the plastic of the gear.

I popped a new bearing in another gear and will give it a shot at lunch time.

Post some pics if you can when you make your night blades... that would be cool to see.

Have you seen this? http://www.hobbycity.com/hobbycity/...?idProduct=8467

What an awesome price, $35

I'm thinking of ordering a few of them... kinda like disposable heli's

Let us know what happens with that bearing!! Are you sure it's not locking up with something else?? or that the main shaft is getting stuck somewhere??

Yeah I will but there's going to be lots of testing first, just to make sure I don't cut my neck off

That's a great price for a heli!! I wonder what's wrong with it or how it flies??? It looks exactly like the t-rex though except for the head button, I guess they needed to change something to keep align from sueing them

OH-6 are you at school?

LOL! I hope you are learning while doing!

Hey Odam, I am curious to know about that bearing problem as well.
Let us know your findings.

That heli is an awesome price. It does look like some cheaper plastic parts, but easily replaceable! I might grab one just to see what its like. surely cheaper than buying just a replacement frame for a 450!

hehe hey sonny yeah I was at school, just got home... It sucks though since not enough people took one of the classes that I needed they had to change one of our classes for tommorow Darn it I had planned to study on tuesdays and thursdays but now it's going to be so weird going mon, tues, weds, and friday

Hey odam make sure that you don't position the pinion too far from the main gear!! That might just be your problem, there has to be a little slack but not too much or you'll stip the gears really fast(specially with an upgraded motor!)

Well, it isn't actually the one way causing the problem either. I tried a brand new one and same thing happened. So off I went to the local hobby shop to see what they thought, and I think he got it... It could be the shaft the one way goes onto, the hollow one in the other plastic gear. If it gets worn, or out of round, it will cause the one way to slip, generating lots of heat, melting the plastic on the gear...

I'm lucky to have two fantastic hobby shops close by, both owned and staffed by seasoned heli flyers...

So, I grabbed some more parts, just so I can start over with new pieces, and got er all fixed up here at my desk at work. I brought my tools with me as well as a bunch of parts. Now if I can manage to get out of here a little early, I might actually get some flying in today before it gets dark...

OH-6 its not stripping the gear, its actually melting the plastic around the metal sleeve that you press the one way bearing into. That causes the sleeve to spin in the plastic gear... the teeth are fine...

but good point...

I too have meted the one-way into the gear it happens when I start real hard tic tocs I spun 3 then I started putting some green loctite on barring haven't spun one sense! I know green is for metal to metal but it seem to add just enough grip to hold it and if it cant spin it wont heat up and melt the plastic

If you order one of those $35 helis I would like to see what you get
I tried some cheepos early last year and whats left of them is still sitting in a box and they were $99 knock offs $35 seem way too cheep

Where exactly did you put the green loctite? Did you put it on the aluminum sleeve and then press it back into the plastic gear?

I tried Gorilla Glue, but it didn't hold at all I was thinking of trying CA, but I don't have my hopes up....

It seems a shame to throw away a gear that has no stripped teeth!

WooHoo! Problem solved. The guy at the shop was right, I replaced the shaft on the bottom gear that the one way slips over, and its working fine now. I did lower my throttle curve to 95%, the headspeed was too high for the stock plastic head and wooden blades. I stopped on the way home from work (managed to get out a bit early) and set the camera on the ground, and did some full stick climbs, its not all that impressive on the video, but here it is anyhow...

Watch at YouTube

Should be available in hi def shortly...

You can tell that the motor doesnt bog at all.

Much more impressive in person...

Hey Odam,

Yeah, I had my grandson over the weekend so it was busy around here, today i repaired the servo wire on the hdx and It still did the same thing, so i guess that wasn't it. I took all servo's out of the receiver and bound it again. Then i found that the servo's were not set up properly, the swash was not moving up and down very far at all. So I am going from scratch on the servo hubs and going to set it up again, so i get the swash movement i should have. Then I'll go through the DX7 setup as best as I know how and see if I can get it right. I'm hoping I find the problem with the cutting out stuff. I gotta read through the tread and see what happened with your gear.
Only sim flying lately.

dang odam I would have never guessed that! But I'm glad your flying again!

I got my stuff to start experimenting with the blades today, I'll set it up in a piece of plastic and later I'll start figuring out the circuit to minimize the parts that will go on the blades I decided to avoid using red LED's as those take resistors and I don't want to add any more weight to it!

Hey sonny if you need help let us know!!

Wish I were closer Sonny, I'd give ya a hand... I was bored tonight, nothing to fix, so I took the Voyager apart, fixed a few things with it, like replaced some screws with bolts holding the servos on, and even fixed the receiver tray on the front that was broken and just dangling...

Then I cut off the balance leads from 2 of my 4 apogee lipos (they are weird, wont fit in my charger) and then cut the balance leads off my little CP Pro Lipos (3S 800mah) and put them on the apogee's. Now at least I can balance them... I dont really care about the little ones...

I scraped all the old paint off my Raptor Canopy and my Voyager Canopy, gonna repaint them now that I have the airbrushes. I have them primed now, will sand and reprime... paint later this week, not sure what colors or design yet.

'sposed to be cold and windy for the next couple days I think maybe I'll tear the Raptor down completely just to see how it goes together...

hay oh-6 well i got the fuse out of storage and took some pics of it turns out there was a scale drawing on the box and it was made by none other than LARRY JOLLY MODLE PRODUCTS dont know if you are fimilar with him or not. the mechanics that are in the drawing are gmp cobra mechanics. the cobra was a 40/50 machine that everybody put 60 size engines in set my 600n next to it and i think it would fit just fine with some mild fabricationas the boon on the t-rex may be larger than the cobra had but i think you could make it work. it is a 500 fuse with the windshield there is not in the greatest condition and has 2 cracks at the bottom not sure if it in the area that is used or cut off also the fiberglass is slightly deformed and will need to be put in a jig and heated with a heat fun to bring it back into shape or just put some structur in and glass over it but i think this will work for what you want. pics in my gallory

I took the servo's off the hdx 450 to get the servo arms off, the ball links were on the wrong hole! They are hitec servo's Ive never used them before, I guess it doesn't matter too much except the tail servo. The servo arms are sure not standing out as much to write home about, thats for sure. Kind of flimsy! I will hook the esc up to the reciever and see if it cuts the power when energized. Then I'll check the servo's before i put them back in! This frame is one where the servo's are mounted vertically so they are harder to work on, you wanna make sure the arms and servo's are centered! Boy am i learning stuff! Who said you can't teach an old dog new tricks!!

Hey Odam, Yeah I wish we were closer as well. So far i don't have too much for flying buddies around here, there are a few, but just having gotten into it at the end of the flying season around here, i didn't meet too many people that fly often. Just to go to the gym now and then on weekends.

LOL sonny I'm glad you're learning new things!! Let us know if the RX cut's off when you move the servos!!

Hehe I went to my HS yesterday so the guys could see the airwolf with lights on it. Everyone liked it a lot and than I hovered a little, it was a little scary though because there was no room for mistakes

Hey COBRA that looks great, it sure looks like it's going to take some work to finish it but I like it!! Are the landing gears broken where the pipes go in?? Let me know how much you want for it, oh yeah I sure don't know who that guy is But let me know what you want for it and were you able to find the tail parts??
