[youtube][/youtube]Hi Ali great to see a thead like this,i have built three FEJ Hawks and like you say all is not perfect but not a major disaster either,it has taken me and others a while 3/4 years infact to get fej to make some changes ie, to heavy/aerials like bricks etc and at last it seems things are coming together.
When you get to the exhaust pipe i have found it to short on all three of my Hawks.To get the C/G right with out adding weight to the nose the engine needs to be as far forward as possable,which makes the exhaust to short!! i have found that the pipe needs to be 900mm long.
I will watch with great interest how you find it,although i expect you will be fitting a 180/200 engine where i was using a 160.
After watching the video of your flight at B I T W i was quite amazed at the take off as the Hawk came off the runway like it was in a lift,not at all with the nose high,guess there was more flap than i have used,Hope to see you at CJ on the 28th regards Keith
