Update:
Finally now that I have urge to fly this model, weather can't make up it's mind!, was out with it yesterday testing everything, taxing it around but it was crazy windy at 24C temp. So couldn't do high speed test runs or even a small hop flight. Thought it would be same or better today, yet its 11C and same crazy windy....oh well let's see when it will be good to it. But im happy to say, all systems are working well except for air in landing gears system. Im still not sure if I should leave it empty in current locked down position or fill it up buy im not going to operate landing gears on first 3 or 4 flights...
