RE: "Little toot" Centre of gravity
I fitted a saito 125 4 stroke, and set the C of G to about 125mm, as discussed above. Flew the model over the weekend, and the results were great - it looked and sounded pretty damn good, if I do say it myself!
If anything is still feels a little nose heavy, also the wooden pushrod for the elevator is less than precise, I'll maybe convert to closed loop or more likely fit a couple of direct acting servos at the rear. I might need to move the battery forward a little to compensate for the latter.
So I just wanted to say thanks to both of you for being so helpful.
Regards
Rob
