Sure that's not shipping damage. Need much better (BIGGER) pictures.

micro heli should have to recall all the crappy gears they sold...

mine lasted 30 sec before it stripped.

Looks like a lazy photoshop job when they put that ad together.

I know it's just a lousy photoshop job, but thought it was funny considering the circumstances.

What if the main gear was machined out of aliminum? I mean on that fits tight?

Wouldn't work because 1.) You would need to have the gears constantly greased, but with the current design the grease would fly out and 2.) there would be too much heat created.

Bottom line is Align screwed the pooch on the design. It's a 90, they should have designed it so you can adjust the mesh.

I do disagree. If all tolerances are the same (which they should be) there would no need to adjust the mesh if machind and designed properly. I think the real problem here is 1 of 2 things.

1 Poor quality material used for main gear
2 design allows engine to flex enough and strips the gear when power is applied.

That's not it, people with the mesh adjusted properly are still stripping gears. The heli needs MOD 1 gears, plain and simple.

Since when has Align shown the ability to keep tolerances consistent

With all due respect - I disagree with your disagree!

Even if a company can keep the tolerances within spec, you still can have a case called tolerance stack. Normally, with a good manufacturer, you get a bell curve around the middle of the spec. Some parts are correct, and some parts are to the left of the spec, and some to the right.

So in a worst case scenerio, if part "a" was to the left of the spec, and part "b" was to the right, you would have a very large tolerance stack. In this case, the mesh would be off quite a bit.

But all this is mute - we're talking about Align here!!!

Some manufacturers miss the spec, or the bell curve is not centered on the spec. In that case your tolerance stack is even worse by definition!!

And I once again have to disagree with your disagreement. The design itself is good. Its the quality of materials and QC..

Yeah but I'll bet your pre-stripped gears will come in a bag of 20, a real cost saver.

Wow - I have to completely agree with you on that point!

When I was first building my 700N I noticed it uses very little in the way of frame braces. Due to the wide frame design, they should do the opposite.

They could probably get away with less bracing if they made the frame material thicker. But they didn't do that either. I'd say the entire frame should be the same thickness as the bottom plate.

Heck, they don't even use a 3rd bearing block for the main shaft.

Bottom Line: They pretty much designed-in and guaranteed a flexible frame!

I am really loving my 700. I stripped a maingear, replaced it, and have had no problems since. yeah, align probably should have just gone with a mod 1 gear to begin with. but most of the 700's out there are working fine. if you go to a funfly and ask people most of them have not had issues, and you almost never see it actually happen. its just on the forums that most people are having issues. its because the people that don't have issues don't post about not having issues.

700N 91HZ/SB-20 690V2 V's
90SG 91HZ/SB-20 710V2 V's
