Hi Howard,
Thanks for posting… Your posts are great and informative. On a picture of these kits I noticed that a lot of them had “Home Made” propellers. Did the Guillow’s 5 inch propeller (Red) come with the kits? Even my humble “Home Made” propeller did better than a Peck Polymer 4.25 inch prop trimmed to 3.75 inch.
Thank you for the complement. It's been said that the worst balsa prop you make will be better than the best plastic prop you can buy. Well...maybe. Methinks that was said by someone who has never used an Ikara prop. I've done exceptional balsa props and some that were utter failures. Some people do very well with plastic props, if you want to build really light or if you are ever going to build something like a twin pusher or any other model that has to use left and right handed props on the same airplane you had better learn how to make your own.
This is a twin pusher, if you've never seen one.

Looking at your photo I have to ask, how are you trimming your tissue at the edges of the frames? I use a sanding block with 220 grit paper. It cuts the excess tissue right off. Also, the tissue looks a bit coarse, like silkspan. If it is silkspan (as supplied in the larger Guillow's kits) you can get much lighter with tissue. See if you can get Esaki tissue at a local hobby shop. Even a good, tight, domestic tissue, (Easybuilt sells some excellent ones.) will work better than silkspan for anything 24" span or less.
Still trying to be helpful.
