You need to get a standard glow trainer until you learn what makes a good plane design and proper power to weight ratio.

but

for 5-6 foot trainer you need an engine weight of of about .6-.7KG with an output of 1.2-1.5HP.
for your engine you need a 7-8 foot trainer and find a way to increase the output to 2.2HP or get the weight to under 1.1 KG and even then your going to be marginally powered and over weight

If your going to use that engine you more than likely going to need to prop it for 7000-8000 RPM, which mean your going to have to have really long landing gear to clear the prop which will be in the 15-17 inch range, part of doing in alone and by yourself with no experience mean allot of guessing so your going to have to buy allot of props to get it right. No one is going to be able to give you any specifics on the engine since every engine conversion is a custom rig, though prop hubs are available.
