Hi Dave,

Flown the plane today screwed the pump out 1/8 turn anti clockwise and made up 30%nitro 20% coolpower half LV and Half standard.
After using the new fuel the trim was not low enough to shut of the engine sat there idling at 1200 rpm for a minute or so and still picked back up to full throttle.
eventualy it did stop.
Topend i set full throttle peaked the engine at 8800 then richen it up to 8500 with a 18x8 APC.
vertical was unlimited with a 6.1kg plane behind it i think thats about 13.5 ponds it just kept going up until you could not see it.
the engine now runs flawlessley all flights easy to start.


Thanks for your help


Lawrie
