Hirobo Sukhoi
 

I'm putting together Hirobo Sukhoi and have a question for any of you who have put one together. I'm ready to mount my engine and noticed a slight problem. If I use the engine scribe lines on the firewall that Hirobo used, the engine will be about 3/8" low from the center of the firewall. To me this doesn't sound correct, but I would like to hear what you guys have done.

Thanks!!!
