The Thinder Tiger 4 stroke (55) will not work with the engine mount given in the kit. The flange on the engine covers the holes in the mount. Can I redrill holes in the mount to match the engine and not destroy the strenght of the engine mount? I think that would be the easiest way to mount the engine. Or should I find another engine mount and redrill the holes in the firewall. Will the additional holes in the firewall hurt? Never have had to do any modifications before so I'm a little nerves. I don't want to destroy the ARF before I finish it
Thanks for your help!!

Hard to believe that no one has modify an engine mount. You guys are normally pretty quick to have a solution. Do you think I can add additional holes in the mount and still be ok or will I be taking a chance of the mount coming apart when the engine is running?

Yes, you can drill new holes in the mount. It will not hurt anything. just make sure you get the new holes so that the engine is straight and where you need it.

My Feedback: (1)
I checked an old mount from a Kaos and you'll be moving the engine forward so the carb clears the back. This may make the plane nose heavy. What I do on ARFs is to install everything except the rudder and elevator servos. Then I check the CG. If it is nose heavy, I move one or both servos to the rear. Usually, I do the rudder first. I rubber band or tape it in place and check the CG.
Using this method, you hopefully won't have to add weight.
I generally put my rudder servo in front of the fin on top of the fuselage. Then I hook it up pull-pull. Some people don't like it outside, but I do so I can see the hook-up. The elevator servo goes in the side.
I am attaching a photo of my ULtra Stick 40 with the servo in front of the tail and a pull-pull.
