Hootowl, When you have a little more experience in the aircraft industry you will realise that carbon will not form a stress crack, so as time passes nothing on the heli will change due to frame flex. 17 years as an airframe tech.
Been in manufacturing all my life. 10 years of it at Boeing with a major part of that time involved with 767, 777 fixed leading edge manufacture (much of which is composites) and the V-22 Osprey of which is mainly carbon fiber.

Composites can delaminate when subjected to continuous vibration induced flexing. I shouldn't have said "crack". Yes, the composites can take an awful lot of shaking and not be effected.

What type of airframes do you work on?


r/chelisrme,

There is a difference in power available with this mod. I'm not just saying this, I am experiencing it. All axial loads now run on properly raced thrust bearings instead of bearings designed for radial loads. They are 10mm. I got them here or you can find them at Ricks.

No it's not possible that my thrust bearing mod is causing more flexing. The original bearings are still there.

Those new Align metal bearing blocks look great. Looks like they have a retainer for the bearings instead of using a locktited press fit. See the four screws?

These would be a nice addition to my thrust bearing mod. The thrust bearing would be sitting on a nice flat metal surface instead of a split between two plastic halves.

I’m more than confident I'll re-kit it before it has chance to delaminate. Although I will not be carrying out any NDT (non destructive testing) to find out if it has, as any de-lam (cracks) will not be visible anyway. Harrier GR7 (AV8B) started on airframes when I was 17.

How is it that the "pros" can fly the crap out of these helis and the rest of us 99% fliers find all of the flexing and flaws in the designs? Worried about how this might fail or how this next new metal upgrade will fix this or that. Performance increases with metal upgrades or that .02 sec faster servos, come on.

Just freaking fly the heli It flies just fine and I am sure your main blades flex more than the frame in the air.

You can keep finding all of the things to tinker and try to "fix" but just watch the videos of the heli, it can handle the shake rattle and roll

tauscnc,

I agree. The question was good though and it brings out ideas.

Keep in mind it's the pros that find the issues and often are the first ones to get their hands on the upgrades, or develop them themselves.

I can't see where the metal main bearing blocks will fix any frame flex,the frames flex in front of the blocks. If you want to bling the heli out,just bling it you dont need any excuse to do it. I can see some 8 pound 600's on the way.

Flew alot today. Love this thing
Metal blocks won't do anything for the flexing. They have the same footprint against the frames.

I don't think this heli has a problem.

Hey Hoot,I had a fly bar break at the start of the threads today on a Basic Standard Sport 600N 3d Pro today. Found the paddle and the threaded part of the flybar was still in the paddle.

Hey I meant to ask you..are you using two of those thrust bearings? I was wondering what the thickness of the bearing,because a bearing could be put between the auto bearing and the bottom bearing.you wouldnt need the collar on top under the swash. What ya think?

Yea I'm using one under the top bearing block and one above the middle bearing block.

Good idea except the thrust is pretty thick... like 5mm (3 parts)

That would move the gear a lot. Have to look

Just looked.

The only way something like that would work is if you mod the middle bearing block so it sits higher. If you didn't, the gear set would move down, interfere with the tail output gear and you would lose some pitch.
