Default RE: FEJ Large Hawk


ORIGINAL: jetmodeller

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

Hi Keith. I was expecting more flak from you to be honest.. especially after all the ribbing I have given you and your FEJ's over the years... Especially those aerials LOL [&:]
If truth be known.. I am actually writing this after test flying the model this weekend. I wasn't expecting it to work out this way, but the build was so quick and hassle free that it just happened that way
Thanks for the heads up on the tailpipe. Looks like another bit of your advice has sunk in as mine fitted perfectly. No nose weight was added, and if anything. I am thinking of using lighter batteries in the nose after my test flights.
I have gone with a King tech 180 ( More on that later ) and found the power to be perfect. I am using my normal ( by sight ) flap settings and found take off and landings to be spot on. Flight number three in fact took off so quickly that it caught me and the camera man off guard.
All being well, I will have it at ABingdon on the 28th.
Regards Al
