Yeh l got that, l think most of the problem is the TX. When l swapped from a 3810 to a DX7 all these problems seemed to go away.

Flybars. Who needs `em.

So I'm back!!!

How'd it go you ask? Well... let's just say it's been a while since I've flown to my ability (well, what I thought my ability was anyway).

Long story short, I balled it up ! I normally fly in a confined space and never really push my skill much. Further, I have some sh!tty packs that I use to work on basics (good ones as well). Well, I went to a larger place today and was so excited that I had space to fly, that I just went all out (on my sh!tty packs mind you). I knew that this particular pack didn't have that much oomph, but I didn't want to hold back anymore. Anyway, I started doing some hurricanes and was going into a hurricane figure 8. The first circuit was fine, the second circuit, I think I over banked and added collective to compensate (yup, here's where it all started). At this point, the heli is really carving in the air and then it started to bog. My headspeed went from like 3000 to about 2200 in about 2 seconds. At this point, it's carving and falling out the sky and then it carved itself a grave on the ground. One of the blades was even sticking straight up out the ground! The thing is, I honestly believe that if I was using one of my good packs, I could have just powered through it. Ah well, it didn't bother me too much (it is too beautiful a day to be upset about anything). It was fun while it lasted. It's the first time I've really been able to FLY a heli. Still it's a testament that my skills have regressed a bit, cause this wouldn't have happened to me a few months ago.

As for the interaction, it was MUCH MUCH MUCH better. But there was one problem that remained. In an inverted climbout, it would roll right. Like a significant roll, not slight. I couldn't explain it. I even landed it and checked it out on the ground. At full negative pitch, the swash is still level. My only explanation for this is that one of my servos is not going to the proper position under load. It was perfectly fine upright.

I'm going to go ahead and repair it and do a few tests to find the culprit. I may need to buy a new servo. On a positive note, this gives me an excuse to try those new TP blades!

...now where was I, dh/dt = BS-dx/dt
I will fly you forever... till earth do us part

Even adjusting the links a half turn would be too much. As of right now though (by twisting the links on the balls), it's as close as it's going to get and I don't need an offset in the radio (one click in the radio is too much).
I am not too sure about other high end radios but the JR 12x allows you to set how large the increment of movement is per each click/ beep of trim, be it subtrim or atv. this is an awesome feature when you are trying to get the swash perfect.

hi

IF the servo is going ..

Make sure you replace ALL THREE because all three work better if purchased together..

IMHO

hi

I have always replaced the CCPM servos with all three if one goes out.. I was told a long time ago that this is for the best performance ... I dont know if there is any truth to that.. Its just what Ive always done..

You will love them. These are by far my favorite blades on my 450s.

make sure the EXPO on your pitch curves are ENABLED
What does that expo actually do??

It reduces swash interaction.

Well I don't think it does that I think that's a useful side-effect in some cases.

What it does is smooth out the curve of the servo horns to be a linear one (physical). As natrually servo horns are faster in the centre.

Please excuse my lack of terminology!

Bottom line always have it on, then just increase your collective/cyclic if needed.
