Wildhare 50CC Edge V2
Looks just like mine did. Rudder should be pull/pull not push pull. 50cc is plenty for this airplane, I have a strong preference for DA engines based on their product support. Mine was reliable for 10 years, then developed a carb problem. DA rebuilt the carb for total cost of $9.00, kit cost only, no shipping! They also repaired my ignition when the plug boot was pulled out from a c****, a word that is not in my lexicon!
I would only use digital servos on all flight surfaces. They hold better. Don't know the specifics of the servos you cite. Use a "monster" on the rudder as it is a single servo unlike some of the two or three servo installations.
This plane will do anything you ask of it - precision aerobatics, 3D, etc. The only downside is that WH is out of business and there are few if any spare parts on the market. So if you have a c**** and can't repair something, it's time for a new airplane.
I wish Tom Fawcett all the best in his continued retirement, but I sure miss his products and support!
