I am currently trying to build a twin engine me-262 with wemotec 480 fan units. I believe I have settled on two hacker b40 13s motors, running parallel castle creations 35amp speed controls and running off one tanic 6660 4s3p lipo. Motocalc says this will work (both engines together drawing 67.6 amps), but to be honest I have no idea. I have not bought anything yet, and am VERY open to suggestions. The aircraft will have its own battery, no BEC problem, weigh approx 4 lbs empty, 600 sq in wing area, with retracts and flaps. It is a custom built model, not a kit. Any help would be, well, helpful.

Thanks
Jeff
