ciao bubba! six great flights today ! the problem was on the header tank ( hely's small raptor). you buy it allready settled, but when i get to see inside the fuel lines where smaller than normal! now with another header ( normal dubro 2 o.) and normal lines with uniflow setup, great power and easy to set needle.( only one turn max. needle open ! plenty of fuel ! ).
thank you , without your suggestion i never will go to see inside lines!-
plase what kind of prop did you ( waturi ) use on your 1.60 fx ?
ciao, francesco
