Protos Newb here, Need some help with HS

[BlazinBones]

Bought my first Protos 500 used in here but in great condition. Put a BeastX on it as the original owner kept his V-bar. Almost done with the setup but I don't know if my headspeed is completely off or is this normal for my setup. My setup consist of the following:

• HK 880kv motor
• 15T Pinion
• CC Ice Lite 75
• BeastX with AR7000 and sat
• Voltz 6s 2650mah 35c packs.

My max obtainable HS at 100% is 1700rpm. I swapped the speed control for an Align 70a and got the same results. Tried other Lipo packs but no difference. Seems to be a bit low from what I been reading in here. Sounds good and hovers great but I want to make sure as I'm a complete Protos Newb. BTW, It was love at first site,

Check your throttle endpoints and curve first since you seem to have the same issue with the Align ESC. Also what are you using to measure your head speed?

Endpoints are 100% U&D, I started with a new model so I never even got to touch them. Same with throttle curves, only altered my Normal Curve to obtain 100% without liftoff. I'm using a Hobbico Digital Tach which is on point with all my other heli's. I gather something is wrong by your reply?

This is what the previous owner said to me prior to sale;

"The Castle is already set up for the Protos. I believe the head speeds are 1550 1600 and 1700. Motor and ESC run very cool and the spool up is very soft."

So now I'm

What's your normal curve at?

At 100% throttle, with 6S, 15T pinion and 880Kv motor, you should be seeing somewhere around 3K rpm.

Use this head speed calc to see what you should be getting:

I did you the that HS calculator, thats exactly why I thought something just aint right after seeing the calculated results. At first, I thought it may have something to do with the ESC but then it yielded the same results with a second esc.

No matter what I do to my normal curve, it maxes out at 1700 non-governed.

I wonder, is there a governor in the beastX or ESC?

I just tripled checked the esc to make sure the Gov is disabled and it is. The ESC sends the throttle signals directly to the receiver so that leaves BeastX out of the equation.

Mmm, Can you check a few things?

Make sure you have over 22.2V? (maybe you have a dead cell?)

Make sure your pinion is really a 15t?

Make sure your motor is really a 880kv?

Can you try with a different motor? Seems like your weak link..

• Battery starting voltage was 24.94V and after testing is down to 22.50V
• Counted the pinion 4 times and they all added to 15
• The motor is a Scorpion 3026-880kv or at least thats what it says on the can
• I have no other motor

I'll give it another go tomorrow with a fresh battery and a 3rd ESC and report. Thanks

Seems like your throttle end points in the ESC might be messed up (Assuming the Align has the same features as the YGE.. Which I don't know about).

Sorry about the motor, it is not the weak link, I thought you had a cheap Hobbyking motor when I read HK 880Kv.. My bad. That motor is AWESOME.

Unsure what it is, but you should get around 2800RPM easily with that setup (That's what I have)

Thanks for all your suggestions. I appreciate you trying. The Align esc is straight forward with minimal programmable features and endpoints is not one of them. Furthermore, the Align ESC came of my "Go To" 550e which I fly almost daily and flew yesterday with it as well. I'm going to try tomorrow again and put fresh batteries on my Tach as I want to make sure is not my Tach since it's had those batt's for a while.

The Protos sounds healthy and hovers great with what appears to be good head speed (judging visually) and response.

Maybe your timing is not set properly?

Or maybe your ESC is not set for 6S?

Check my video, does the heli sound like this: (at 1:40)

You running a CC ESC? What is your Spoolup setting and Gain and HS set at?

[Thalios]

Me, i'm with a MSH YGE 60A.

Crap LOL

Ok guys, for some reason (unknown of course) I manged to get some good headspeed now, . This is what I did, factory reset the ICE 75, went over the entire setup process again and started with a freshly charged battery. She has more than enough headspeed now.
