Well i finally did them, we went to a big open and flat field today and there was some wind down low and alot up high making it perfect for autos. i did my first one and thought "This is fun!" so i did about 10 more.. and on my 11th one i was just flaring it and then going to land it when the wind just changed directions on me causing heli to Drop fast and hit the ground..

As soon as it hit the ground i heard this big Slap sound and I knew exactly what it was, i went over to it and there was a dent in the tailboom.. The blades were completely fine, i couldnt even tell which one hit the boom. The boom's dent is small enough its not even coming close to the belt and its not hurting the flying, so i flew probably 3 more flights on it and continued to do autos (if i woulda stopped after the boom strike i woulda lost all confidence), but now i can do them fine with no problem!

Gonna open the tail boom and look at the dent, if its not too bad ill just pop it out, if its bad ill just replace boom.

Dent
I had one that looked like that for a short time, and later it turned into a two piece boom. I have tried to remove the dents by forcing a rod through the boom, but now I just run it till there is no doubt that it need to be replaced.
Autos are fun, but I usually get carried away and think that I can do a perfect auto no matter what.

If everything is running fine I wouldn't worry about getting rid of the pumb (that's bump spelled backwards), indentation. I've flown with them before and as long as the boom is straight and there is just a bit of a bump then not a problem. Then again, Tailbooms are cheap.

2 sets of "Super hoops"
2 flybars
1 50 size Tail Belt

Umm, none, as the belt is a mile away from the dent. Osi, I have that same dent in three or four of my machines. With a Raptor, it's almost a given. I often thought of pre-denting the new booms, to give the blade clearance!

oh..really...put some dykem on the dent with a small paint brush.
(use lipstick if you dont know what dykem is)
that belt slaps all around in the tube...
you will see dykem transferred from the dent to the belt.
do your tires hit the speed bump?
or did you miss the driveway?

I saw one tail boom homemade from steel conduit
with a seam inside.
the belt was about half ground away
whats all this brown powder in the tailcase?

lol

I must be doing something wrong then. On a Raptor, the belt is no where near the dent we are talking about.

Maybe Venom will come out with a unit that monitors dent temperature ( DTM ), with a downlink, so you can be constantly updated during the flight.

Auto's! (tail boom dent)
on a raptor 30,the m/s pulls the belt from the bottom of the tail shaft to the left of the m/s.
that is called the drive side.
the return side is from the right of the m/s.. to the top of the tail shaft.the belt is the loosest right where the blades hit the boom

15mm? thats over 1/2 an inch lol
its only a 22mm boom
on the outside
so yours has 15mm clearence on the top and bottom?
lol
you've never seen how any belt or chain slaps up and down?

think what you want...
