I think they are .40 - .50 size versions of their larger CMPro counterparts. I love these planes, they look great and they seem to have a favorable reputation. I haven't heard of any issues with the Spitfire, Zero, Hellcat in particular. I am curious as to how much engine weight would balance on of these... I am guessing 18 - 20 oz...
These are being offered on EBAY by "fzhu2719" $159...
