Castle Creations Telemetry Link for Futaba Sbus2

[cml001]

Anyone using the new CC telemetry link? I'm having trouble with the reading of the rpm... My motor is an 10 pole... And the E7SE gear ratio is 10.08... Those figures are entered in my 18SZ but its seemingly giving me motor rpm and not actual HS rpm... Anything I missed? Suggestions?

Just got mine in the mail yesterday and am currently working 12hr nights... hopefully I'll get to play with it soon. Maybe Chris can chime in.

Kool.

I think Chris Sexton got one as well as Alan Butler the owner of HeliLids. I have one waiting on time to install.

I just did the update on my radio to make this work last night. I 'll be installing on my 766 with Castle 160 tonight and hopefully testing tomorrow. I'll let you know how it goes!

I have all functionality that I'm suppose to.. But as stated, the rpm seems to be motor rpm and not head speed rpm... That's the only part I can't figure out... Lol..

be sure the gear ratio is entered properly on the CC GRAPH. not on the page where you tell it what HS to fly at, but when you use the graph to look at amp draw and power out and all, that one. I have seen the 2 be different at times. they are supposed to be linked together, but I have seen them not transfer before.

I think he is referring to the RPM display on the telemetry of the radio.  I think I got mine setup, won't be able to test today. But seems to work on the bench.

right. but like the graph gets reads it and does the math, the CC telemetry link would be pulling from the same place in the ESC, right? or am I thinking about this wrong?

The Graph is a PC function, that second setting isn't transmitted to the ESC. Which is why you have to change the gearing from one heli to another in the graph program.

ahh, got ya. showing my great programming skills here aren't I! LOL

You're pretty close to the issue though, as with the graph on the PC, the TX needs to know the gearing to properly read RPM.  I haven't gotten that far in mine yet. Just got the sensors registered. I'll report back details, once I sort them out

[Danny Dugger]

Clay, I'm just now setting mine up, haven't tested yet. But did you set your sensor type to "brushless motor" instead of "magnet" in your radio? I thought maybe this sounded like a good culprit for you.

[cml001]

Don't recall a selection for it... It asks for pole count & gear ratio.. But I'll check! Thanks

[Danny Dugger]

I wasn't setting up the correct slot. Now I'm feeling your pain lol... need to play with this some more
