Think twice about the V-Max engines. I bought one of these for my trainer 4 years ago and I broke it in properly, but the Piston pin broke (the pin that holds the connecting rod in the piston). My mentor and flight instructor has been around the hobby for 50+ years and said he had never seen that pin break. Even after he has crashed. I will say that the distributor fixed the engine but I immediately sold it because I had lost confidence in the product. And I got spoiled with the OS engines
I'm not saying you won't have good success with it, I am just letting you know my experience.
