Thanks for the info. guys
Now Got some more questions.
I have been using hitec 5645mg (5 of them) with only one battery a Hobbico HydriMax 6.0V 2000mAh Flat 4/5A U Panasonic and haven noticed any loss of power in the servos and the charge last a very long time.
Now if I go with this same servos and 1 jr8611 for rudder or if I sell this servos I may go with 5 8611 and 2 standard, what will I need for battery power??? same for ignition and also like to see some pics of some setup.
I will go with one of this 2 28% not sure yet wichone, and will buy the Da-50 for it and If I sold the plane I'm selling now I'll go with the 8611 (5).
I'm really ignorant about anything that has to do with Gas engines/and ignition etc so since I want to get it right the first time.
Thank you all again!!!
