Certainly not a new model, Ron’s Scottish Aviation Bulldog is a 60(ish)” span scale model that was powered for a long time by a 4-stroke i.c.engine.
I think Ron would be the first to tell you that the model was a bit of a pig under this power-train so he decided to undertake an experiment to convert it to electric.
Seen in these pictures with the cowl off the bulldog is not only lighter but also a lot more docile in the sky. Ron has been enjoying flying it regularly at the field this year. What used to be a sometimes “when-I’m-feeling-brave” model has now become a firm favourite.
