Can someone please post an in depth video on how to get the gear mesh correctly set-up on a Rave 450 flybar heli. The location is at the TT gear and Main Gear. The two beveled gears keep stripping.

I am having problems with stripping the gears constantly.

Thx it is greatly appreciated

First off : Are you using the black tail gears?

Yeah i have four packs of the black gears. I went though four of them using the 3 certain gear types in the package already trying figure out why i am striiping them so quickly and often.

What I have noticed is that the black gears are slightly longer than the white gears. When you you assemble the torque tube into the tail boom step 5-1+ page 24. Press on one end of the gears and watch for the other end to pop out a little. If this happens I do one of two things. I either trim the end of the gear that engages the torque tube and or lengthen the slot that engages the TT.
If this push test is overlooked then the mesh is too tight and creates heat which melts the gears.

Once you get the gears from popping out then follow the rest of the manual for setting gear mesh.
This should resolve what you are experiencing.

Here is the post that SkyDancer posted awhile back about setting the gear mesh:

Per Skydancer:

This is the way I like to set the Tail Rotor gear lash:

First, remove the tail boom from the model (leave the boom clamps tight on the tail boom).

Next, remove the front tail transition support on the front of the tail boom clamp.

Now, check to see if there is any end play on the tail rotor output shaft in the TR gearbox. If so, use shims to eliminate the end play.

Now, check to see how much clearance is in the bevel gears in the tail rotor gear box. If it seems like too much, first remove the 2X10mm allen screw that pins the TR gear box to the bottom of the tail boom (step 5-2) and then loosen the 2X6mm allen screw that clamps the tail rotor gear box to the tail boom. Now, just move the tail rotor gear box in a little on the tail boom to tighten up the gear lash then retighten the 2X6mm screw on the clamp.

Then, I like to spin the tail rotor using my finger on the front bevel gear on the torque tube. It should be very smooth without any binding and have a little gear lash (plastic gears don't wear in). When it's smooth reinstall the 2X10mm allen screw that pins the TR gearbox to the tail boom.

Now, reinstall the front tail transition assembly. Check the clearance between these bevel gears. If they seem too loose, loosen the front tail boom clamp screw (on the bottom) and slide the front tail boom clamp rearward. This is how you adjust the gear mesh on the front bevel gears.

Now, spin the TR assembly again using the 24T flat gear and all should be smooth (no irregular drag) and you will have a little gear lash.

Once the front bevel gears have been adjusted the clamping screw on the bottom of the front tail boom clamp should NOT be loosened again.

Now, reinstall the tail boom and tighten up all screws. Check to see if there is very much clearance between the 24T flat gear and the 100T tail drive gear. To set the mesh on the 100T/24T flat gears, loosen the 4 screws holding the "front" tail boom clamp to the side frames, and the single clamping screw on the bottom of the "rear" tail boom clamp. Now loosen the 2 horizontal fin screws (which holds the clamp for the tail boom supports to the tail boom and then pull the tail boom rearward to loosen the mesh between the 100T/24T flat gears. If for some reason this does not give you enough clearance (it does in my case) you might try enlarging the side frame holes for the "front" tail boom clamp (only) to allow the front tail boom clamp to slide rearward between the side frames in order to loosen the mesh between the flat gears.
The tail drive system should run smooth and the tip of my TR blades move back and forth about 8mm (accumulated play).

Just take it one step at a time, it will be easy....

Thx Mystar 60 and MarshallB

@Mystar 60 they are melting to a nub. No gear teeth at all on either bevel gears.

@Marshall thanks for the instructions i will print them out for the manual.

Thx

I think the thing that I've seen is primarily 2 things. Make sure the black gear is recessed all the way into the bearings in the Boom, and, do ot have the mesh too tight. Too tight and they will melt.

Also check and make sure your CF torque tube is not cracked. If it is, it leads to gear stripping.

Got the gears in and check the TT no twists or splints in it.

Reinstalled the gears, then it started raining this morning

so I will probably give a shot tomorrow afternoon.

Thx again for the help.

Good news had a little break from the rain. so I did a quick little hover for a minute, and no stripped gears. I was so relieve that nothing happen, so now the little bird can fly.
