if it broken.....glue the bast#$d...keep flying..i tell the wife my crashes cost £20! works for me

I had a rough landing in an auto and I knocked 4 teeth in a row off of the front bevel gear on the TT. I replaced the gears as a set and installed a 700 tail fin. A few rough autos later and no stripped teeth. With the longer fin (I have not measured it yet) there is more clearance than with the 600 tail fin. I'm keeping the TT for now, if I break more gears (something like $14 a set) I may change over in the future.Mark

I fly belt but try this:

Add two small 1/8" spacers between the back landing strut and the frames. This will lift the tail up enough to clear the dirt in a rough auto.
It's easy to find an excuse to do wrong. Hard is not to find an excuse to do right.

They do, the problem is you stripped it out :}

Don't take this the wrong way but learn to land more smoothly. The gears hold up great until you hit the dirt with them. That's no fault of the gears.________________

Yup! I was thinking the same! And if the gears wont strip something else will break!

I think TT drives are a great learning tool to keep you from "ignoring" the tail. I stripped the gears on my third flight and since then have not stripped any from a normal landing.Jack

We have used TT on our 600e when the conversion came out. We broke few gears on the ground (no big deal) and crashed two when low tic-toc touched the tail blade (still no big deal). However, when we lost the tail in the air twice due to hard piro-reversal, we swapped back to the belt drive.

At 2350-2400 head speed, piro reversal is extra hard on the bevel gears without gyro softening. Since changing back, we have not lost a single heli due to tail. But we lost one to a dumb thumb.

I imagine 600N will stand up much better than 600e due to much lower input power and head speed.

I fly with the belt drive. But I redrilled the stock tail fin to mount lower down on the boom. With this mod the the tail blades stay about 3/8" further from the ground and it was free. I also took a spare 600 fin and mounted it on my 500 for the same reason.Jeff

Run 92mm tail blades and the longer 700 fin, then the only one that can be blamed for stripped gears are your thumbs. I have been running the TT for over 2 yrs and have NEVER stripped a tail gear. You can also run the tail blades a little looser so they will just fold back when in contact with mother earth.**Unattended children will be givin a shot of espresso and a puppy**

I don't know what all the fuss is about. I've trashed a couple of sets of tail blades but never stripped a gear (12+ gallons on a 600N). Maybe I'm due...

I don't know what all the fuss is about, either.

I'd "UN" torque the tail blades. You may have them too tight? Just a thought.

I've replace a few stripped gears, but... as of late. I haven't had any problems with the tail "knock on wood". Even dug a trench on an auto, nothing?

If you running 2400 head speed, something has got to give. That spead will definatly eat the belt guides on a belt system.
