Hi Guys.
I live in Dubai and have recently brought a new G booster 80+ turbine and installed it in my Boomerang Sprint.
I have had 5 flights with it and it has gone like a dream. OAT has been in the mid to high 30c.
Today I started it as usual and it was a bit rough and spluttery and then at the idle point it went woof and shut down with a big cloud of white smoke.
I let it cool down and checked everything, all was ok, and no errors on the Hand held terminal.
On restart it ran up and settled into a good idle, and I ran it to full power and back, all was ok.
taxied out and at run up prior to take off at half throttle it did the same thing, woof and big cloud of white smoke.
We adjusted the acc ramp from default 23 sec to 33 sec and it started again, but after going full throttle and back to idle, and up to half throttle acceleration it still did it, and again at acc ramp 35 secs.

some stats for you.

OAT 32c, high humidity.

ECU is all default except acc ramp at 33 secs.
limits
ídle- 4900
100% - 16400
EGT av 510c
EGT peak 753c.
RPM min /max 34800/164200.
last off, run R
r/c fails, 0.
Total runs 11 ( 4 today)
start aborts, 2
Run aborts, 2
Hr meter, 51.33 min
Engine s/n, 09041  4.53
ECU Firmware, Jetronics vxg3.22.

ECU battery is the supplied 2500 Li Ion battery, fully charged.Fuel supply is ok as it will go to full throttle and sit there ok.

I am aware of issues with the larger G boosters not running in high humidity, but was assured that the smaller turbines were ok.

Any advise please?

Thanks
