Good spot Pat

I have a CC 45 and it looks the same - you can just about see the "CASTLE CREMATIONS" wording on the battery leads when you look for it now that I know it's there ...

Blue Bird BMS 127WV servos


I just done a quick servo speed test on these servo, using the Tarot ZYX programmer. My Batts has been on storage mode for a very long time also they are really old. Probably not the best candidates to use. Also my HW 60A V4 ESC is only rated to go at a max 8V instead of 8.4V which the manufacturer recommends.

Anyways you can see on the pics, they seem to be fast. Also no slop. I can't wait to try them on my TRex 250(cyclics) and 450PRO(cyclics), X360 (cyclics+tail), and Trex 470L(cyclics+tail)

Thank you to Atomic Skull for recommending me these servos

Looks promising


That seems to tally quite well with the claimed spec of 0.05s. I used to use a similar CX program box as a servo tester, until it quit working one day.. Always had to run the speed tests a few times, and use an average since results were quite variable.

It looks like a promising servo for small helis, 450's even, though the mounting lugs on the nylon case looks a bit fragile. Should be fine on a heli tail, though, and it's a lot lighter than the KST115/215 servos.

That was my thought when he posted using on a 470L and the X360 ??

Perhaps a follow up post after trying them out for a bit ??

Just looking at the pic, it would seem to be the ultra micro size, maybe a bit small?

It should be fine, this servo reminds me of the old Turnigy DS480. The only problem with that servo was that it was easy to fry with a slight over voltage. As you can see my ESC is set to 8V, but it is going higher than 8V. So in a way I'm glad my ESC doesn't do 8.4V as it may fry the servo. But on the other hand I would like to see if this BMS servo would be able to handle slightly higher than 8.4V and will it fry or not?

Curiosity got the best of me. I wanted to see if the BMS 127WV servo can handle 8.4V. Seems to work fine

Hobbyking 20A Watt Meter


I thought I'd test out my old HK 20A Watt meter since I already have a servo to test. It seems like it's not that precise on reading low current.

Uh, if that's the way his local hobby shop runs wiring, he'd better find another hobby shop!

Though I personally think everyone should wire their heli to their liking.

But if you're paying top dollar to a hobby shop to build your heli, I can see Pa Flyer's point of view.
