I am hoping someone might help me or at least point me in the right direction. I have a FW 190 kit drawn by Don Lien. It's 1/5 scale 80" wingspan. Any way my problem,

I am planning to put a ZDZ 40 cc engine in it instead of the Webra Bully it calls for. To do this I will need to cut out the firewall and sink it back about 1" back from the front of the plane. I'm trying to find out if this kit has any engine thrust built into the molds when laying up the Fuse. I talked to one guy that has built it and he said he didn't think the original firewall had any built in thrust, however I thought all planes had usually some degree of down thrust and right thrust built into the firewall.

Anyway, any help or info you could provide me will be greatly appreciated.

Thanks again
