Does yours look like mine? Yes

Did you replace the capacitor on the tail motor as a test? No, as Heli-max said this is only a filter for noise, not impacting the amperage.

Did you try a different motor? No, two EFLH1322 are on order to try.

If you did, did you also solder the different motor? This is my 3rd motor that I have soldered - it works, but blows the 3amp fuse.

Are you just touching the connections with your soldering iron just long enough to melt the solder and make the connection? Yes

What type of soldering iron are you using? Resin core type from Radio Shack for hobbiest.

Perhaps you have some damaged wire insulation that is grounding out during the startup / vibration of the heli? While I did not remove the entire, it looked fine when I removed the motor for its replacement. I will replace the wiring that has zero ohm resistance using DMM, if nothing else is found.

I am waiting for a call back from Heli-max helihotline on moving up to a 5amp fuse.
