Nothing like having the components on hand to see I have made a bunch of rookie mistakes. wall1wall1wall1
wall1First, the ESC, Blue Arrow BA-BS 6D. Had I read the reviews I would have seen there are "quality control" issues with this model. Polarity of the battery leads is reversed. Burns out if hooked up as indicated. It may be fixed in later production runs, maybe not. How is one to know? Hobby King is getting a lot of consumer flames on this one! Rightly so IMHO. Not the right design for my application anyway, too heavy for what it does. Didn't even mean to order it in the first place!
wall1 Second, the flysky receiver requires 6V (nominally). I've only got 1S. THe Turnigy 5A 1S Brushless ESC might solve this problem without adding more battery weight. The reviews indicate the boost is just to the receiver supply. It's in stock. But is 5V enough for the RX? Reviewing our old posts, I'm not sure. I'm going to try getting in touch with Hobby Partz support on this one.
wall1The Hobby King 1.7 g micro servos are strictly 1S (4.2V max)capable according to the discussion groups. So, it Turnigy boosted ESC just juices the receiver, I think that solves the problem. If the flysky receiver can really perform on just 5V!
I'm kind of stuck here - between micro and mini if you will. Like the transmitter/receiver package, but it doesn't really like 1S power. I require very small servos due to space and weight constraints. Don't want the bird to get much heavier. The horizontal action of the HK 1.7 servos is very helpful in a tight space.
Then their is the problem of electrical connections. The receiver wants mini connectors. The rest of the components want micro. I'm willing to connect wire to wire if need be. If I crack the RX case can I just take out the pin connectors and solder directly to something? Are there going to be heat sink issues? I have not soldered anything small in a very long time! I have a feeling there is an adapter to mate the pins on the receiver with the micro plug on the servos, but can't seem to find it.
The Hobby King lipo charger defaults to 2A charge for the 1S. Wow, that seems high, but lipos play by there own rules. I suppose I should not go lower than 2A. I checked out the charger using a handy compatible 12V DC supply, but unfortunately it is only rated to .75 amp. So, I guess it's off to radio shack again. My local hobby store has a $20 option which charges a singe Turnigy 1S using a bunch of rechargeable Nicads. Simple and compact, but you only get about 4 charges from a bank of 8 Nicads. Seems pretty inelegant to me.
Well, the good news is I can move on to making journeyman mistakes soon, and expert mistakes in the more distant future.
