I had one on my testbench a while back, and that is an absolutely decent engine for its money. They are a bit weird in that if you compare the Force .46 and the Force .52, it is as if they are made by different factories. Completely different design and execution, but both are pretty decent runners and easy to get along with. Get a fuel with 5% Nitro and a medium plug (like an OS #8 or an Enya #3 or so) and you should be OK. Propsize around 11 x 6.
Have fun!
PS: I assume you bought it from JustEngines? Good supplier, excellent service, I was a very frequent customer there until Brexit happened.
