It all started when Trex 700 exploded due to a Main blade failure..repairs £500..
My confidence has taken a severe hit..still not 100% TBH.
A severe lack of belief has caused me to just freeze on the sticks everytime when I got into more awkward positions.. 7 crashes later with my poor 600 and things are begining to get better! (previously I had the one in six months)
Moneys tight and could do without all the crashes..but thats part and parcel of R/C heli's. Finally fixed the 700 for Parkhall/3DC....a few flights in and it sheds a taill blade grip mid piro flip (bolt sheared off) 10' of the deck and in she goes..Grrr..One flight on the blades I was testing..Fixed that
Repaired and flown at Parkhall and now trying to get some decent practice for 3DC about 4 gallons in.. and the motor ( YS ST) decides to destroy itself for no apparent reason..was on the money with a cool backplate and didn't suddenly go lean..just a very abrupt change in engine note, power was gone instantly..Hit Hold and down.
Well opened it up..no corrosion or oddities with the brg but the rest is toast..Piston, Liner, Conrod, ring , brg, head, crankcase all marked up and scored..bits of alloy everywhere. Cant even get the damned thing apart as its part jammed up with the debris
Not sure whats the cause was till I get her apart but cant get the blooming liner out (jammed part way out) Piston looks to be whole and was not seized although the liner is scored from bits... i'm guessing the ring is still intact as its alloy bits I'm seeing. Big end of Conrod looks very iffy..that or Piston around the Gudgeon pin area where I cant yet see...
HEEELLPPPP...GRRRRRR
