Chopped my tail off!
I've been working on piro flips on the sim for a while. I've done some single flips on my trex450, but chickened out and stopped after one or two flips. Yesterday I went for it and kept it going for about 30 seconds. I did this a couple of times and my nerves were getting better so my timing was getting better too. I swapped the battery, got back to a safe altitude, and went at it again. After about five or six flips, I heard the boom strike and saw the tail fly off. It's all busted pretty good because I was up high. The question is why my blades hit the tail. Could my blades have not been tight enough? Is it dampening in the head? Or is there something else that could have caused this?

Your blades are not the problem. Try Trueblood dampeners or add shims, some even use fuel tubing.Please stand by for faster service!

I run stiff dampeners as well, but what is the fuel tubing trick?

i actually saw this happen on a vibe 50 2 weeks ago during a piroflip was sad but his case we all thought it was the upper mixer on the blade grip itself coming off were any of your links off when it was on the ground?Velocity 50 "99.9999999999999% of an atom is empty space." also 01001000 01001001

No trick. You just replace your dampers with a bit of fuel tubing.

Fuel tubing is very soft, so would'nt that translate into a blade strike faster then having a stiff set of Dampeners?"I just don't Listen" "

Not all fuel tube is super soft Brian. Get a nitro, and you would know this. By the way Brian i went to school all over the world. You know nothing.

i am typing at work and don't have time to punctuate everything! k-3rd grade i went to school in in Germany at GERMAN schools not American and then i went to school all over the united states i assure you i know how to punctuate and type i find it pointless on an internet forum especially for such a short reply

EDIT:nice deleting your post Brian what i posted was not a paragraph anyways..

I figured I would man up, and leave it alone.

I'm looking at all my Fuel Tubing here, and I have none, that is nearly as hard as my dampeners. Is there a different grade of (FT) for helicopters, then let's say Nitro truck's.

I have the light blue and red tubing.

well i have 2 kinds on mine the external line is pretty hard as in if you bend a lot it maintains its form even at like 180 degrees of bend and then the fuel tube inside the tank is super soft to flex around during flight to keep the clunk in the fuelVelocity 50 "99.9999999999999% of an atom is empty space." also 01001000 01001001

Could having my main blades too loose in the grips have contributed to this?

depends on HOW loose but i would say no you should be able to flick your blades and they should move a few inches at the tip then stop if like this then there right when the heli comes to speed they become rigid due to centrifugal forceVelocity 50 "99.9999999999999% of an atom is empty space." also 01001000 01001001
