no no... MA are basically just a copy of the hirobo gears... and the MA metal gears are basically just a copy ofthe Hiribo metal gears. beggest difference being the Hirobo ones are helical.

To the individual(s) who saw fit to imply that I wouldn't be concerned if the new gears didn't run smoothly out on the back end of my tailboom, ignorance must be bliss, and you clearly don't have a clue how anal retentive I really am. Go do a search and find out how picky I am about dialing a cooling fan down to 1/4 thou. I can put you into contact with a few current and former world team members who can perhaps vouch for me. Maybe Gordie will too. And if you think that I'll hold back an opinion when a design on a part isn't right, there's another situation where you just don't have any idea what you're talking about. I do generally do it in another manner rather than flame a product I don't yet own. Gordie does as well. Something about class and tact....

What is truly mnd boggling here is that this new gearbox is being made out as a POS with its molded gears, yet the vast majority of people do not yet own one, hadn't a single thing to do with its development, or even have held one in their hands. By all means query Eric Larson or Henry Caldwell, who helped do the R&D on the box and see if he thinks his tail box is vibrating POS. Here's another idea. Perhaps, just perhaps, wait until you've actually flown the box stock unit (or at least seen it flown) before you immediately assume it won't work or go installing Hirobo gears based on no other data other than that the Japanese gears are cut and the MA ones are molded.

Oh yeah..........I'm a seriously conservative republican; I had fun Tues night.

Molded Tail Gears
Dear Dr. Ben

Didn't mean to imply you wouldn't admit to something if u knew it was wrong...That being said, Molded gears have much more porosity then machine gears thus molded gears are weaker. You can prove this yourself by simply cutting an old Robbe Gear or MA gear in half and looking at the pores compared to a machined gear. This is true of any extrusion as well as compared to a solid piece of Nylon. You are assuming that molded gears are a perfect subsitute where history proves this not to be the case. Your right I have not tried the new gears as of yet and probably should wait until they are out there and have been tested....I am merely stating facts about molded anything as compared to machined.

I wonder if the guys testing them have actually compared the gears on two SEPARATE helicopters BACK TO BACK... machine verses the molded gears..or just evaluated the molded gears???I know the molded gears on the Raptors don't hold up They are weak and transmitt some vibration as mentioned by Todd Bennett at one of the FunFlys I attended....Bottom line me thinks this is all about profit not quality....

I watched one of the test pilots crash this weekend when on take off (a piro flip take off) the tail gears came apart, you actually heard the tail gears break (very loud bang) he lost the tail hit hold and in he went. One gear was completely gone and the other was almost completely gone. I dont know if these were the production gears or not ( I dont believe so).

Well I would guess 90% of us would never put a set of gears through that kind of punishment. I would like to say that MA definately has some of the most capable 3D flyers testing the new equipment, and if something is going to fail they will definately find it

I along with Eric Larson have been flying the open gearbox for some time now. I know I've had atleast 50 or more flights on it.

I've noticed that the tail holds better, tail authority is 100% better, and the motor seems to make more power. I've flown the open tailbox back to back with the stock gearbox , and I must say thier is a very noticable difference. .

Eric and myself have tested a couple of different gears , and the ones that broke with me this weekend "ARE NOT " production ones. I believe the final production one will be 100% ok.

It takes alot of R-n-D to develop a bullet proof product . And as we all know it is a trial and error type situation. But I can assure you that the final production one will be bullet proof. I will be glad to let some of you fly my machine this weekend in Mulberry to see for yourself.

I am sure HC is true to what he is saying. And if I were there I would gladly take him up on his flight offer. Just don't ask to see his brain. I am sure he will show it to you.

He knows what I mean.

Build it, fly it, crash it. Repeat as often as needed.

And if you do Fly his Rig, beware if he is standing behind you with his hand in a pocket If you were at the last couple of fly ins you'll know what I'm talking about

porosity
Well you need to consider the mix of the material, the heat of the press and the cycle time all of which you dont know. Thats the only way the issue of porosity could be a factor. High density vs low density material dictates that. I just went through that whole lesson with a product that I am making.
