New low KV motor setup


I am trying to equip my SS for longer flight times.

I have bought the following items to accomplish this:

1. Hobbywing Pentium 40A ESC
2. Motor: XYH35-30 1100kv 15A Brushless Outrunner (http://www.giantshark.co.uk/xyh3530-...-p-402740.html). I also have the 1400kv version to use if the 1100 should fail.
3. 8x4 Prop / 8x6 Prop / 7x6 Prop
4. Gens Ace 3300 25C 3S Lipo Battery (I also have a couple of 2200 mah to use if too heavy)

What do you guys think of this setup?

What Prop do you suggest?

I am going to have to solder extension cords for the motor leads using 3,5mm bullet connectors, any comments on that (except for keeping them as short as possible I guess).

I use the CNC motor mount. Is this the correct mounting of the motor?

Apart from checking the COG after everything has been installed, is there anything else I should do?

That setup will just barely deliver enough thrust to get it flying. Unless you have good deal of flying experience, I would suggest that you do not try that setup. It will be woefully underpowered even if it does fly. sorry for the bad news.
Why did you not use the stock setup? Did you order an ARF?

I think that set up would do just fine with the 7x6 prop and 3 cell.. Quieter too.

Those of you who are flying the Bix V2 can you tell me how it flys? Compared to the V1.

Exactly the same is my experience.

servo reversing


Here is an excellent video on reversing a servo (analog) without using any external wires. I don't know if this procedure is OK with the specktrum tx's or not. Since it is just a direction change, I suspect the spektrum would not even know the servo was changed.

Thanks AJ, I'm going to do just that. It will give me something to do while the Hurricane tries to blow me off this wildcats ass.

It not only works that servo no longer chatters. That was my first experience soldering on a board.

Thanks again AJ.

Having viewed the video, 2 comments -

I'd suggest a dab with a felt tip pen on one of the 2 wires just to make sure you don't resolder back the way it was if you look away with all wires of the same colour.

He mentions and I'd agree, a HK servo tester ~$5, is so handy. You can centre the servo for putting on the arm, cycle the arms continuously and move the arms for checking, all without needing to fire up the Tx.

Thanx, that was generally what I wanted to hear... :-) Can I get a third opinion regarding the comment from previous poster that this setup would be way too underpowered?

I would run it on 4S with an 8x6 3 blade prop :-)

Which screws do I need?


I'm putting together a new Sky Surfer with a new fuselage, wings and tail. The old one crashed, but I still have the motor, ESC, etc. I bought these control horns at HK:

I didn't order any screws with them -- what size do I need for these? I'll get them from a local shop. Also, I got the pinned hinges as well:

http://www.hobbyking.com/hobbyking/s...idProduct=8282

Same screws for this, or different?

Thanks!

I run a 8x6 on a 1200kv motor on 3s 2200mah and goes quite well. So a 1100kv motor should be close in performance.
