Your Lazy bee, Gentle Lady would be much easier to learn on. If it was me knowing what I know now this is what I'd do.
I'd cut the nose off the GL, put your motor on it, rebalance it, set the control surfaces with no more than 3/8" movement. I'd put 30 seconds of fuel in it, if someone there knows how to fly let him trim it for you, if they have a buddy box setup use it.
That's my free advice.
