the green model plane has a thimble drome engine on it. the other 2 don't have markings on them I believe the green engine and the one attached to the right of it are .049 in size.. the bigger plane has a larger motor but no idea what the brand is. I am trying to restore them as they were my uncles. I got the green engine to start, and a slight start on the one next to it, but no luck with the larger engine. I used 1.5v to start the small engines... is the large engine the same?
also using 1/2A castor and 25% nitro fuel mix. Not sure it it is right either
