Hi. First of all, check this link for instructions on setting up your tank. Also, this site is a great place to learn a lot of other stuff about model airplanes.

You can order props from Tower Hobbies. Their website will recommend the correct size (diameter and pitch) for a forty-sized trainer with a .46 engine (probably an 11x4 will work good to start). I'd go with a Master Airscrew black nylon to start. An APC is probably a bit better, but you're likely to break a few, or at least, chew up the ends, and the MA will work fine.

I've never mixed my own fuel, but recommend buying a premade brand. There has to be someone in Canada that'll ship it to you, no?

I haven't recommended flight schools, but what about a club? For $25 bucks a year (and up, depending on the club) and AMA membership, you get a place to fly, make some new friends, find some vets willing to help with your questions and probably a flight intructor or two.

Good luck,

Phil
