3digi and Castle Edge
Hello, need some advice. I would like to try my 3Digi on my Logo 480 which has a Castle edge ESC with RPM out. I have it set to external governor mode. Has anyone used this setup?
My question is do I do the normal "Castle" calibration procedure and then put in my flat curve for the Governor banks? When you calibrate castle for those who don't know, I will get endpoints around 80/75 so the throttle channel in the 3 digi software will not be 0-100. With Vbar and Ikon Governors, you calibrate the castle so the software shows 0-100 for throttle. then you use the sliders to calibrate the ESC. Any help would be appreciated.!! thanks Jeff |

I have been using a Castle Edge lite 100 with a 3digi. I set it to external gov, did the fixed endpoint calibration and put in a flat 80% throttle curve in each flight mode and haven't had any issues. The manual says it would like to see 80 to 100 in the assigned functions monitor, that I think applies more for the rotation rates of the heli than the throttle channel resolution. I was wondering the same when I did mine, but like I say all is working well.

You can easily calibrate any FBL to an esc with fixed points using the 50% voltage method.
You'll likely be flying 6s on your 480. In that case using a 3s instead will minimize the max speed of the motor. So what I do is reduce my end points in the 3Digi, configuration menu, throttle limits, say 50/50, and slowly decrease the lower limit till you hear the arming tones. Then spool up with no blades, and slowly increase the positive limit till you hear the motor no longer gaining speed. This is the point where the esc is outputting 100%. Key point, you will never reach 100% output if you don't reduce the voltage. Verify the lower limit by testing the arming of the esc. Add a few increments to the low limit for safety. I'm double checking if 3Digi has an internal sub trim for the throttle channel. They do. See attached pic. Edited my info above... On a side note, it is recommended to use V-curves since these are defaulted to in the event of an rpm sensor failure. Last edited by Dmaxison; 02-08-2017 at 06:29 AM.. Reason: Correction to process |
