Well, went out this morning (6:00am) with the Magnum PI Hughes 500D and after working so hard to get this one smooth, I just about crashed it this morning. When I installed the battery I didn't even think the balance wires would touch the motor and I didn't pay attention to where they were laying. I powered her up and everything looked great, took off in a scale like pattern and got about 10 ft up and 25 yrds out and motor cut out, no way to auto that low and slow so I did what most of us do and froze..... She sank a few feet and then I heard the motor start up and on it went like nothing happen, so with knees shaking I got it back and landed perfectly on my landing pad (don't know how I did that) Now what, took it home and pulled off the front cabin to find the battery balance wire caught between the motor and motor mount, the motor had sucked the wire into it would be my guess because it was on the right side of the motor which is the same rotation, the black wire was torn out and the rest as you can see on the connector were rubbing the motor, so I'm thinking failsafe kicked in or what???? I put a new balance connector on the battery (6S 5000) and expected the worse but all the cells balanced perfectly and I hovered it to run it down and all seems fine. Did I get away with one or what????

Here is the picture of the connector after I cut each wire one at a time and soldered on a new one, also the marks it left on the Scorpion, couple of the marks are actually deep scratches from the metal clips on the end of each wire......

Lesson is, keep all loose wires tied up out of the way. !!!!

Auto?
It might have made it, but by time you actually respond to it and think, is this really happening, did the motor just quit, I wasn't thinking auto, I was thinking its a CRASH landing and yes these things are heavy. Hirobo Evo mechanics are heavy anyway and then you add a heavy Hughes 500 fuselage, and a heavy 6S 5000 battery plus onboard battery for electronics and you have a flying brick. I don't practice autos unless its on my sim. No use breaking a perfectly flying heli if the auto goes bad

So Barry, your going to be at Scale Masters? Don't think I'm going to make it this year but if I do I might bring some extra cash for that R22......

Yeah, I'll be there. I wouldn't miss it I plan to bring the Century R22 and the Koala for sale, possibly the smaller vario huey too. I'll be flying my big R22, 300 and 700 size AS350. Bring wheelbarrows full of cash or gold coins, cuz you're gonna want to buy all 3...
