Default G-Force Trex 700 Clutch Block setup

OK G-force sent me their new replacement clutch block setup for the Trex700. This allows adjustment of the pinion to main gear backlash thus helping reduce the possibility of stripping your main gear.

Not much else to say other then this thing is really designed well and a thing of beauty!

On with the vids:

Video Link ->Overview of the clutch block and motor mount system (35 Megs)

Video Link ->AAARGH! Got a stripped screw? Here is how get get one out! (19 Megs)

Video Link ->Assembly and Installation of the clutch block (60 Megs)

Video Link ->Installing and adjusting the motor mount (49 Megs)

Thats it! Hope this was helpful....

Bob

This is very nice the way you can adjust the clutch and motor.

One thing about the bottom plate, can't they have the same ideal in adjusting it also, instead of having to file the bottom plate? and the nuts on the clutch can't it be captured like the nuts on the motor mounts?

Thanks

Robert

I suppose they could.... suggest it to Garf at G-Force... Maybe it's a space issue though as there may not be enough room in the motor mount bottom for a slotted hole and a nut?

Bob,

You are correct. There is not enough room in the bottom area of the engine mounts to capture a locknut.

Regards,
Garf

Bob,

I noticed that your main gear showed noticeable backlash before the clutch block was installed. Was it like that when you built the 700N?

No it was not and that developed over time since the build.

looks good but I personally think that all of these fixes fall short of the real issue. Align should have designed the heli with 3 main shaft bearing blocks. The 600 has one at the bottom of the shaft to prevent movement, the 700 should have the same thing. The metal clutch block is a necessary part on most heli's, plastic is just too weak for this application. Unfortunatly the design of the frames does not allow for adding of a lower main shaft block. I would be interested in seing just how much movement there is at the bottom of the shaft durning flight.

finless, how the heck do you dremel a slot that is not rounded out so the screwdriver doesn't just jump out. I am down here working on my 700 with a soldering iron a dremel and a flathead screwdriver and I can not dremel a slot, just a rounded out useless slot.
