Hi Smelly
Glad things are going well and you are well and truely on the way..
Trim the motor in ie down to start and as you get faster and up on the plane trim it out / back.
You will probably feel the steering get easier ie not pull as hard as you you trim the motor out and if you go too far you will pass the "sweet spot"
Just practise and you will be fine.
I've left you last repairs to others as you now have a good following and I've been sort of tied up dealing with multiple poilce and insurance people re this "BARS" thing we are trying to get up.
Good luck with it, just keep asking.
Cheers
Chimo
