I have been paying very close attention to this thread since I am considering my next build after the BUSA Eindecker 90. And I really like the looks of the BUSA Sopwith Pup in either 1/6th or 1/4 scale and the price is right, but what I'm worried about is how they fly as being I am somewhat new to flying compared to others here and I would like to hear from those who fly the BUSA Pups.

How would they compare to say, Sig four stars?

Is there a major difference that should dictate I go to something else before flying a BUSA Pup?

Thanks.
