ive been flying my marutaka dc 3 with 2xsaito 30 and the power is enough for me..its the same size
as TF -dc3 but i dont know if it weighs less,however,it sounds and flies great with this setup and it is easy to
land with these engines running,you can have a little bit higher idle and still get the speed down..
tried it at first with os 40 and i didnt like it at all then,too fast for my taste/bokis
