Want to say a few things about my build.

I started building mine last night, mounted the wing up OK, added the ply reinforcement, Mounted the belly pan(didn't fit the out line of the wing real well, but it's OK). Hinged the Aileron's,They needed the slots cleaned out, but lined up pretty nice. Mounted the Horizontal stab, While trimming the covering off some of the stiping just lifted off, so I had to get out the Iron and went over everything. Fits tight but it's pepindicular to the wing. Rudder fin needed some work to get it vertical and I had to get the dremel out and hog out the bottom of the fuse for the tail wheel assembly. Got the rudder hinged. On to the motor mount..........\\

This is what gets my gull, Being my second Model Tech kit I should have known better,
So I clamp the beam mounts to the OS .25, sqaure it up and then take my measurements, the firewall has a vertical and a horizontal thrust lines already scribed in. So next step is to just mark the location of the mounts verticaly, then the instrcutions tell you to mark the top horizontal line 3/8" above thrust line and then down 23/64ths below thrust line. Guess what? That produces a total dimension of .375 + .359 =.734 or 3/4"aprx(19mm). The distance between mounting holes on the back of the beam is 28mm or 1.1".
Glad I didn't get the drill OUT!.

Why do manufactures let this happen? For pete's sake, take a kit give it to one of the non modeling workers and tell them to build it!
That will tell you right off where you scewed up.
Oh well I'm blowing off some steam over a fairly minor issue, but it just ticks me off.


So to all of you out there, any guess as to how much thrust offset should be included in the mounting of the engine?
