Bearhawk Original model vs. B model question

[Greg L]

Here's a question I've been curious about for the builders/flyers of the original Bearhawk. Can you or have any of you made changes to an original Bearhawk to upgrade it to the "B" model. Principally, has anyone changed their wing from the original 4412 wing to the Riblett Airfoil wing? If so, does the wing location (Fore/Aft) on the fuselage change? Does the incidence angle change? Does the Horz. Stab. down force angle change as well? If anyone has changed wings, have you indeed noticed the different flight characteristics between the two wing/airfoil designs?

I think Mark Goldberg converted his demo bird from an A wing to a B wing. He might be able to speak to what is involved and also the flight characteristics. jaredyates has flown both wings and many engine combos.
