I'm getting ready to mock up/mount my engine(thunder tiger.91 4 stroke) to its mounts and to the firewall. I noticed the building plans do incorporate in a degree and a half of "down thrust",but I dont see ANY "right thrust" designed in there anywhere. Do I not need it,or should I account for alittle right thrust when mounting my engine on the mount rails? I'm using an anti-vibration Dubro rubber mounted mount. Its an expensive mount and I want to make sure I've got everything right before I do drilling the holes in the rail. So whats the deal with it not having any right thrust?


Oh,and while I'm at it,I'll ask this too....I may have to reposition the firewall about 1/2-3/4" back further in the fuselage to be able to get the motor back far enough because of that bulky motor mount. Is there gonna be enough room in the fuel tank compartment to still fit the tank in to pull this off? I know alot of you guys have built this kit,and might be able to help me here. I'm using a 14oz Du-bro tank many of you have also installed. I just dont want the motor to stick out the front too far.

Please don't read into the instructions...if it's an ARF you might not see the off set...if its a kit and the instructions didn't call for it don't put it in..in any case it might not be needed...if it is you can add it later by putting washers or a shim under the engine mount...never try and put the engine in the engine mount crooked to get an offset..
