Cees, Top Flite made no changes to Ed's 1962 Nats airplane, cause Ed did the kit plans. If you check the October 1962 RCM&E plans with the Top Flite and MAN plan they are all very close dimensionally. And I do not think that the kit plan was available before the African adventure, or Ed would have sent that to Dennis instead of the brown paper, so it was not ready before the African visit. The models in the box must have been very close to each other, or the wing of one would not have fitted the other. The radio fit must have been the same too, as Ed only had one Tx in Africa, so far as we can tell. Therefore the fuselages would have to the same, dimensionally, to fit the gear.
