ok guys i have been doing some extensive research on the DL50 that i already bought,the engine arived two days ago,i bought it with the intention of using it in a new great planes 1/3 scale pitts special biplane,the plane is alreay done and all im waiting on is just a few ods and ends,well as soon as the engine arived i was so exited,this is my first giant scale plane and my first gas engine,well i dont want to get too much into detail but i am in need of some help,the manula sais to mount not a gas engine but a nitro engine mesuring 6 1/2 inches from the firewall to the prop washer otherwise the cowl will not fit properly,well seems the DL 50 is about 6 3/4 or slightly longer,so what now?the only thing i can think of is to modify the engine box to make it alittlebit shorter since i cant just cut the engine standoffs due to the carb clearance,and to be honest i wouldnt like to do it,has anyone mounted a DL 50 in this particular plane sucsesfully?any tips or ideas would be helpfull and much appreciated
