do or don,t

Titanium gets bross when heated to fast or at one spot.
it will crystalize , and behaves like glass.
you will suffer from small cracks , eventually leading to pipe implosions.(seen it and heard it happen)
leading to a crash.
i have seen 2 identical models , both of them suffered from a failed pipe at almost the same number of flights.
one could land , with just minor damage to his rudder servo (cable fried due to the heat comming out of the crack)
other model was a total loss.
however we fly 2 C-arf flash with both titanium pipes , for over 140 flights in less then 6 months.
still no problem , only difference i see is the length of the pipe that could be a problem.
maybe to much vibrations.
lots of people use them , but i would not sell them anymore just there are to many variables then can lead to early distruction (hot starts , wrong allignments etc)

the weight difference was almost 300 grams..[:-]
