I got a Carl Goldberg Tiger 2 40 ARF with a Magnum XLS 46 2 stroke and it flies good, but a guy at my club switched over to electric and was kind enough to give me a brand new Magnum 91 4 stroke. What do you guys think of it for the Tiger? It fits perfectly, just wondering if it's too much for this airframe or if I should reinforce the firewall.

Thanks
