Default Building Roy Clough Sheet Metal Susie....engine?

Now that I have acquired the full-size plans for the 1955 Roy Clough "Sheet Metal Susie", I am trying to determine what replacement engine would be the closest match for what this plane was designed to accomodate. According to the write up text that accompanies the original plans, Roy states that a "Cub .14" would be the smallest engine, and the "O&R .23" being at the top of the largest. Since I was born in the same year that Roy designed this plane, I'm not familiar at all with either of these two powerplants.

I have searched high and low for either of these engines, but they appear to be long gone.... Can someone tell me what would be the closest match to these vintage engines?

For those not familiar with the "Susie", this aircraft is indeed a control-line model, crafted nearly entirely out of .019 aluminum sheet. The plans state that with fuel aboard, a flying weight is going to be in the vicinity of 24 ounces, so it's definitely not a lightweight!. Wingspan is approximately 27".....and Ihaven't yet been able to determine what prop was used on the original....

My sincerest thanks to anyone who can offer any background or info.....

Jim

Try an OS.15 or an early Fox.15. I'll post this link so others can see the model.

The model sure looks very different fromthe balsaplaneswe're moreused to seeing.
I'll admit to being a fan of Roy's designs, I built and flew his .049 powerd C/L autogyro in early 1960's. It flew very well and amazed us all.We'd all like to see some photos of your build............John.

Sure, John.....I'll post up some pics when I have it ready to go.....Roy states that you can expect a full up flying weight of about 24 oz, but I'm doing everything possible to try and come in under that amount...we'll see!

I'm also working on building another of Roy's designs, and this one is for the grandkids.....very simple to build, and flies just as he states!
