Yes, you're probably right, but as I said the plane has already been flown with the forward CG position and the guy who flew it had to use full up elevator trim, and was still struggling!

I have just learnt to fly with a cheap resilient scratch built trainer, and have not worried too much about crashing, so I have been a little cavalier with my flying attitude to say the least, - now I realise this one is much more serious stuff and requires a little thought.

Someone has kindly lent me a little Honda GX 25 four stroke and I think that it will suit the plane better until I have the flying sorted out, being much less powerful than the Stihl. However I've got to be careful not to total the engine!
