Here's one for all you engine gurus.
My mate Rick has cooked his TT 50:-(
It's about three months old, (about 20 tanks) has been running on Prosynth
5% nitro and up until last weekend was fine. Sunday it sounded a bit harsh
and due to operator error, spat out a glow plug at some altitude, not a lot
of height, just enough to make Rick glad he'd been practicing autos on the
sim! (Reflex XLR, awesome graphics!).
A new plug was screwed in, this time tightly, and all seemed to be well.
Yesterday he went out on his own and after a short while phoned me to say
he'd had an impact with the hard bit at the bottom of the sky, bad enough,
all the usual damage, but when he tried to turn the engine over by hand, it
wouldn't. The backplate came off and there was the con-rod in two bits. NO
sign of overheating, nice and clean inside. At the time the engine was
running at more than three turns on the main needle and producing smoke.
The other factor was that he'd changed to Prosynth 10% and had mixed half a
gallon of 10% with the remains of the 5%, thus making approximately 7.5%
Nitro mix.
The motor came from Cyber and they have suggested by mail it was probably
due to a lean run........;-)
Any thoughts......he's going to borrow my Webra 52 in the short term.
