Flybar paddles
Guys,

Bit of advice needed now I've got my SE running good. I've been used to flying 50 sized nitro helis, so the SE is my first small sized electric heli.

I currently have the flybar weights about half way out on the flybar with 25% expo on cyclic controls (running 11T pinion, 430L motor and 325 PRO blades) idle-up is 100,97,95,97,100 and -10/+10 picth, 6deg of cyclic pitch.

Despite being able to hover my 50 on a six pence, the little SE seems extremely reluctant to sit still and 'lock' into a hover, particularly side on. Is this a paddle design issue, or flybar weight/expo issue?

I've also noticed that despite having setup 6 deg of cyclic pitch in all directions, the elevator and aileron react at slightly different speeds? - is this a paddle design issue?

No! Paddles have no effect on servo speed.
Some servos are faster than others & to compensate for this, It's called Program mixing. I think?? Don't know how to do it, but, someday I'll learn how!
Any Takers?????
and one more thing "DON'T BE AFRAID!"

Thanks, but my issues are to do with servo speed - the heli has been setup with no interaction in cyclic or pitch controls.

I guess I'm after advice on setting the SE up to try and get that 'locked' in hover feel (assuming it's possible with small electric birds). Nitro heli's generally don't use flybar weights, but instead solid hovering and flight performance are obtained with a mixture of paddle choice/weight and expo/dual rate.

It is possible to setup an SE heli such that it has very good hovering stability, yet good cyclic response as well - any recommendations?

David,


Swap out the 325 PRO blades for some heavier ones... The 325mm lighted blades make a big difference in stability -vs- the 325 PROs.
Hover is spot on.. But for hot dogging, I love the 325pros.. I run 15% expo..

Not sure on the weight of my lighted blades but I can weigh one and report back if you need the info..

Have a look at my site, below, and follow the new link "TRex". You can get them locked in, and you don't need flybar weights and expo. Make sure all ball joints are running smooth and clear....

AlanR8, your website is very interesting and your reasons for buying your T-rex are almost identical to mine (I have a nice example of an R50 which is expensive to break).

I fully appreciate that the shear size and weight of a nitro will give it a different, perhaps more solid feel to it than my little SE. But I am trying to get the SE to feel as close to my nitro as possible.

I haven't had the time to try out different settings regarding flybar weights/positions and expo settings. As said at present the weights are half way out and 25% expo added. I am beginning to wonder if infact my 'hovering stability issue' is possibly down to the use of the weights and expo? causing my stick inputs to be out of time with the helis reaction - i.e. it's actually not twitchy at all, but sluggish causing the instability.

Assuming the wind is within certain limits, I don't believe that an SE can't be dialed in like a nitro.

Also note that Align are now offering a larger black paddle? does anybody know what effect these are supposed to have?

>>causing my stick inputs to be out of time with the helis reaction

I don't use any fly bar weights, and use a bit of expo on normal mode to calm down the heli on hover.

I thought you meant the heli was twitchy as in heli follows stick movements instantly. Not sluggishness
like you explain in your post. If your experiencing stick sluggishness double check all links like Alan suggest...

As I said guys, because I haven't had the oppurtunity to experiment with different settings - I went with the weights and expo, and the heli certainly doesn't feel locked in a hover.

I was looking for guidance from those people that also fly nitro's (not alienating anybody!) for a recommended flybar/expo combination that would improve the helis feel. I can fly big fast figure 8's and high stall turns with the SE in a similar way to my nitro, but hovering I'm rubbish compared to my R50. I wasn't sure whether to push the weights out to the ends of the flybar, remove them all together, add dual rates for hovering, increase/decrease expo, or change to a more stable paddle design (I don't believe I have tight links, spent ages setting her up real well).

I know with nitro's you can change to lighter paddles which have a greater surface area, this tends to give good cyclic response but aid stability as well?

more cyclic response lessens stability. The gorrilla programmable paddles by heliup are about 1 gram heavier than stock, with the weights removed from them. That should add hover stability. Moving the flybar weights out also improves hover stability, but at the expense of "roll rate", which you can increase your rates to compensate for.

So basically, remove the flybar weights, and decrease the "rates" for smoother locked in hovering feel. Expo for me is about 10%, and I fly thumbs only.
