Hello Steve, I have been on that BTEmodels site before but didn't see that guy from Washington State and the cowl pix. Great photos and THANKS Steve. I had almost decided to just go "stock" but a cowl just sets a plane apart soooooo much. Maybe I am missing something....... How in the world did he get the engine in there. I looked for a seam, where maybe, (after assembly), he cut the cheeks at the firewall. I can only assume that he can "thread" the engine in through the side cylinder hole. I will be running a Saito 1.50 in a 4* 120 so I don't think I want to attach the engine to the mount with just screws. (I'll use bolts and nyloc nuts, and you could not get in with a wrench to hold the nut). I thought maybe I could cut off the cowl..... cut out a "U" shaped hole for the engine, and just slide the cowl on straight back. Then......with the limited access, how in the devil can you attach the cowl??? I have been sent photos of "tab" and dowel pin attachments, but I just can't grasp a solution here. I have not built a lot of planes.... but I feel I can fabricate fairly well..?? .. I like to be able to get to things fairly easy. I just don't know??? I do like the simplicity of using the cheeks for the "frame" of the cowl. It's a little "square shaped", but should have more room inside. Maybe some of you out there can see what I am missing here..... Thanks to all...lownslo
