Phoenix HV85 Soft Start

[skigolfmike]

I'm still in the initial process of getting my H550 setup and I am running the HV85 in Heli Fixed Mode. The problem I'm having is I cannot bring up the power slow enough on initial spool up to keep the heli from spinning out. My setup is:

6S1P FP EVO 30 3200mAh batts
1100kV, 1500W upgrade motor
550mm WoodiesThe relevant settings for the HV85 are:

Heli Fixed Endpoint
Motor Start Power: Low
Throttle Response: Low
Soft Start: Custom 1I'm running out of room for changes. I can go one step lower on soft start and I can go into the custom settings for Motor Start Power and Throttle Response.

At the best I get a 180* spinout. Usually I get more than a turn and I am bringing up the throttle slowly. Any ideas?

Other than that - so far, so good.

one thing to remember... when you initialize the gyro, then if you move the heli, it will try to go back to the original heading that it initialized too...not sure if you are moving the heli after plugging in or not... but if you are, it's worth a look

Are you using the castle link? you can customize the motor start power lower than low, which means you can put your own value. I had lower value than low and I have spool up at medium as low spool up takes 4ever to get to idle up speed.

vicrc: are you running in governor mode? I'm not quite there yet since I'm still playing with setting up the heli. Goes pretty slow when you only have one battery pack. I'm thinking I need to go to 0 on soft start and way low on motor start power.

On my Blade 400, which I am running in governor mode I have soft start on 10, motor start on med and throttle response on medium.

No I am on Heli fixed end point. I set power start custom really low, but set spool up medium. I really like how you can control the soft start and get up to speed fairly quickly. You do need the Castle link to do.

I did not have any luck with the custom setting. Finally ended up at the lowest standard - 24 or 39 or something and it is perfect smooth slow start.

Did you introduce the end points properly? Fire up transmitter with end point low and bring it up one point at a time untill the esc recognizes it? I am at 112% on low stick and 96% at high stick - futaba.
It starts up really, really smooth.

The instructions are not good on this point.

I followed Finless' videos.to set up the end points. No problem there.

Actually, I figured it out, I set spool up at custom 0 (turns out it was set at 4., not even low(2)) I also set throttle response to low and start power to low. Now it's a little too slow, but at least I know I can work it it from here.

Biggest problem I have now is how low I am running the gain on the gyro. I'm at 64-65% I think and just finally got rid of the shake. I'm using the JR 770 gyro and the DS8900G TR servo. I moved the ball link in one hole and that let me raise the gain from 58% to 65%. Maybe it has something to do with the way the gyro is mounted. I wonder if the gyro is bouncing round too much. Maybe I need to do a better job of mounting it.

Yup I did that, I watch Bob do it.

The problem is even after watching Bob do the governator thing I could not get my flat curve around 75 or 80, it reaches max rpm at 43 percent. I gave up on the governor.

There is time to tinker and there is time to fly... I rather be flying.

Another one to give up on gov-mode!!!!!!!!! This is ridiculous, we spend $200.00 plus on ESC plus link only to find it is useless as a gov-mode ESC, I have mailed CC, but to date this is their only answer, dated more than 7 days ago!!!!! Wonder what they use as timepieces in the USA? We should start a petition to CC to rectify this piece of crap!

The biggest problem is, they say to gear my system so I can run at 75-85 percent. My gears are just fine In heli fixed mode, if i gear it any other way it will mess it all up. Duh! I am not trying to get more RPM from my heli.

100%~2600 rpm,
90%~2500 rpm
80%~2300 rpm
75%~2100 rpm

That is what my gears, motor develops at those percentages in fixed mode. When I switch to governor mode it should just reflect those values above instead it run 2600 rpm at 43% throttle. You tell the governor what to do and it does something else, sounds like a bad system :mad: and it doesn't get my vote. How can they mess up something that is so simple? I know I am a noob forgive me as am no expert. However I am happy with it now in heli fixed mode, nice start up and fast spool up, I don't want to wait a minute for spool up, I only have 3 minutes of flight.

My understanding talking to the guys at CC is that the %s in gov mode don't compare to heli fixed mode. It doesn't matter if you get your target rpm at 40% or 100%, the only thing that matters is that your target rpm is between 75%-85% in heli fixed mode.

I also have a Phoenix 35 with the 1.56 software in a Blade 400. One of the things I have found is there are interactions between some of the settings. I was really surprised at how much throttle response affected rpm in gov mode. On the B400 I have throttle response high spool-up medium, gov gain custom @ 29 and it works pretty well.

OTOH, I can see how someone could think all the adjustments needed is a PITA too.

All the adjustments are neat; however, it's pretty easy to adjust yourself right out of the ball park too.

Thanks for that info, then I really don't want to mess with governor mode. I don't have time to fiddle with all the setting to get it right. I am using CC85HV for the HV part anyways.

[skigolfmike]

I can understand why you wouldn't want to mess with it. It's certainly time consuming to get it right. On my Blade 400 I went back to the 1.55 firmware in the Phoenix 35 because I couldn't get the governor gain high enough to prevent bogging without getting tail kicks with 1.56.

I'm still running 1.56 on the HV85, but I am still in heli fixed endpoint mode. I plan to leave it that way until I get the gyro setup and I get a few flights on it. It took a while to get the settings right for the heli to spool up without spinning out. Now it spools up a little too slow. Not sure I'll mess with that because once I go into governor mode the setup is completely different.
