A reply for Flyman..
Both my friend and i purchased this kit and yes it does look real nice once built... we could not find any mention of where the C of G should be but after a bit of working out we found it needed a lot of weight.
I had a 52 engine and my friend put a similar sized 4 stroke .. cant remember the name ... He needed 18oz in his and mine worked out to 2lb yes!! 2lb ...
After trying to decide whether to make the cowl out of lead or just strip out the bits and drive over it in the car it had a reprieve .. another member offered to take it off my hands.
I was glad to get rid of it .. although my buddy persevered with his 18oz of lead and it does look great in the air.. A video can be seen on my website ... www.rcfun.co.uk ... Go to planes and i believe it is on page 4 of the gallery
