Frank Baker 66" Vickers Wellington
Hi Folks,
I am going to build a Frank Baker designed (Hobby Helpers Plan) 66" wingspan Vickers Wellington. It originally flew on 2 - .10 2 cycle engines. Of course, I am going to electrify it. I am just a little leery of the force arrangement as drawn. Particularly the wing & H. stabilizer incidence. Does anyone out there have experience with this design?

RE: Frank Baker 66" Vickers Wellington
Hi the proper incidence depends somewhat on the airfoil of the wing. If a typical semi-symetrical airfoil you can't go wrong with 1 or 2 possitive on wing and zero on stab. Using electric the chance of losing a motor is not very probable so I would go with the 2 down 2 right on motors unless you are using counter rotating props then I would use only 2 down. Remember that two motors/engines are more effecient than a single motor multiplied by 2, more like 2.5. Norm
