Im debating building a dual EDF Mig-29 or F-22 Raptor, from a set of plans that i found on parkjets.com. The question i have is related to the setup of the twin EDFs. Does each fan unit require its own speed control and battery? Or is there a way to connect the motors for each unit to one speed control and battery, or one battery for both speed controls? Im worried that having two batteries may be too much weight for my jet, plus it would cause a larger dent in my pocketbook! [&:] Any advice related to how i can set up my jet would be greatly appreciated.
