Nice models 8178!
25 size can be a lot of fun, and there are some great 25-29 size engines available for little money as the size is not en vogue these days. I must have built a dozen different ones just for fun in the 80's

MK kitted 25 size versions of many of their popular 60 size planes, and a few are still available.


Built one with an OS 32 & small retracts


Built one with a piped OS 28- very fast

OK models 25 size version of Hanno Prettners Supra Fly was another favorite.
