Well, Oldtyme, I am not offended. I used the OS .61 because it is the only engine I had on hand and did not want to purchase another. You were right about having to remove a lot of material from the side of the cowling. I finally
figured out a way to build it so I can get in it, later if necessary.

If I had it to do over again, I would probably elect to purchase a .46. I modified the cowling somewhat as you can see in the pics above. I really didn't like the shape of the original. That is just personal preference and no slam intended.
With the .61 in there I could not round off around the spinner like the plans.

I appreciate all of the comments from Contender owners. I think we must be a unique bunch. I am getting so old, 62, I probably won't be able to fly the durn thing, anyway. I am still on the trainer and will be for at least the next few
months. I don't get to go fly often.

Thanks, again.
