Default How to change the Pitch on a Walkera 4#3b?

I understand that you can change the responsiveness/stability by changing the postitive pitch angle of the paddles. The more positive pitch, the slower the responsiveness, but the more hover stability. The less positive pitch, the faster the responsiveness, but the less hover stability. Right?

So how do you set the pitch? Do you use a guage? What guage will work on such small paddles?

I've experimented with different pitch on the paddles once before, I think it does make a little difference as you say, though it's very hard to tell, I wasn't 100% sure at the time if I was noticing any difference or not. I've never tried a pitch gauge on the paddles, just did it by eye. After trying the paddles pitched both positively and negatively, I settled for just having them flat, since that's how they came in the box.

Though I can remember when I got my original 4#3 back in March, the flybar paddles were set at a positive pitch when I took it out of the box, though the old model is only good for hovering IMO, not nearly as good at forward flight as the A and B.

You had me a bit nervous there Dusty... your first paragraph indicated that your paddles came stock with zero pitch, but then your second paragraph stated that your did actually come with a positive pitch out of the box... mine did too (that is, came out of the box with a positive pitch)... perhaps I should just leave alone.

It was the A and B that came with the paddles set level, though I can remember the paddles on the A were uneven out of the box, probably bounced around in the post, so who knows for sure.

The old 4#3 definitely did come with positive pitch on the paddles, I gave that heli a lot of attention a the time, trying to get it to fly, although it was my inexperience that was the main problem!

I suppose you guys are trying to get more lift from chaning the pitch. There is actually a much surer way to get more power and agility. The trick is to use the new 5-in-1 technology from the 4#3q on your 4#3b. Just follow the link below:

For a heli this size the 4.7g savings will surely translates to a substantial improvement. I ordered the upgrade kit and it's referred to as the 4#3b to 4#3c conversion kit.

Thanks, I've seen the 4#3c, looks impressive. The 2g weight saving the 4#3A has over the 4#3B makes a good difference, so the more weight lost the better IMO. Let us know how it goes when you get it.

Cheers
Dusty

I too have been looking at the 4#3C package... does indeed look awesome!

My original question was on setting the paddle pitch to provide easier, more "docile" behaviors (that is, slowing things down a bit so I could learn how to fly it!).

I made a cardboard measuring tool that I can use to set both paddles to 5 degrees positive pitch. I'm going to make it out of acrylic sheet tomorrow and I'll post a picture.
