ok ive got my maxi put together pretty much and am noticing when the swashplate moves up, the main rotor pitch decreases....is this right? im used to it being the other way around but since this is only my 2cnd heli, im wondering if some are different, plus these jokers are using that crazy floating flybar design....

thanks

Yup, you have it right. That's the way they work.

Wait until you get it in the air and see how smooth it flies!!!!

Dear Danno,

I'm actually kind of glad you thought it seemed wrong. The joker was only my second heli amd I thought I was going mad at the time.

If greg is there, Hi greg, do you have any solutions for the pitch curves or do you have to think in reverse. I've used both plus and minus values for the swash mix but when I've sorted the servo's to go the right way I still nedd a negative pitch curve. am I just being a bit thick?????

Remember to have the blade grip controlled by the trailing edge of the grip. Setup this way, when you give full collective, the swash goes down and gives positive pitch. When you give full low, the swash goes up and gives negative pitch. If for some reason you have the grip controlled on the leading edge, that is your problem.

Hi hobbywood!

What radio do you have? On my futaba radio there is a swash pitch throw setting. On my logo (swash goes up for positive pitch) the setting is something like -43% but on my Joker (swash goes down for positive pitch) it is a positive number (+50%).

Nothing else is reversed for the swash. To roll right the swash must still roll right. To pitch forward the swash must still pitch forward, just like you are used to on your other heli.

Regards,
Nick

Hey, Hobbywood!

Sounds like The Nick got you covered on the swash question, on the pitch curves, they are set up like any other heli.

I'm not a JR guy, (I love it when people fill out their profiles!) but if has a graph like the Futaba does, you should see it going from lower left to upper right.

Ignore what the numbers are, just get it working properly, they will sort themselves out.

Cheers Nick and Greg,

As usual the info is great. The JR hasn't a graph but I get what you mean for the numbers. The settings run from 0-100% on each of the 5 points. Normally as on My Eco's and Logo 0% is full negative pitch and 100% full positive. The Joker with the going down for positive swash means The positive pitch is 0-50% and the negative is 50-100%. I have to program in reverse and my brain doesn't work that well. I wondered if there was a way to allow me to think in similar values to my swash up for positive pitch choppers.

Thanks again guys for the help. Happy choppering

Chris:

You may have your swash settings reversed in your radio, it should still read 0% for full negative pitch.

On Futaba there is a "Swash AFR" setting where you can change it anywhere from 100% positive to 100% negative so everything else reads normally and doesn't effect the cyclic, do you have something like that you can set?

I guess you can work it reversed, but I agree it would be a stretch mentally!

Cheers,
Greg

Swash control
Cheers Greg,

I'm sure there is. I did set the Swash to 120ccpm and the mix to minus 60%, but as I say once the servos all went the right way for cyclic I was back to backwards pitch. More delving into the instruction book!!!!!!!!!!!!!!!!!. My wife says I shopuld do that first but where's the fun in that.

Go into the swash menu, and reverse the percentage you have for pitch. If it is +, hit the decrease key to make it - percentage, and the function is reversed for you.
