[NSRCA-discussion] Plettenberg Advance 30-10 ESC - Questions

[james woodward]

Excellent write up Chad.   I don’t have the data, just set the idle to one speed for landing/flight.   You are right, barely ever bring the throttle to idle during flight.  

I let Jarvis fly the plane 👍.  Was pretty astonished how easy it was.   

This esc is an actual “innovation” in performance and as such, well worth the spend.  

Thank You,
Jim

I have not used the CC or the Jeti Mezon, but I imagine the Mezon is like the Spin.  There is no issue taking a Pletty Advance to 90A, and no issues for big props, in fact the bigger the better.  I use a 22-13, which hits around 85A and 6300 RPM on the ground, any prop made you can run on the motor depending on what you like.

Propellor selection had some impact, I found APC’s brake better than a Falcon on their own so that helped to get the balance better at least for my style.

It is a total re-learn of how you fly, but once you get it I don't think you would want to go back.  For those that don't know, the D3 is produced just for pattern and is custom to every motor, so you order for the motor you want.  There is no programming, no telemetry, nothing really, you just put it in the model setup your tx and fly.  It is a governor controller so setting up your RPM is absolutely critical, if you get it wrong you will not have great results and likely struggle with it.  However the ability to get constant speed is very good, it really turned the Pletty into a setup that has braking as good as anything else IMO.  It manages power for you in a lot of cases, for instance as you pull vertical and the models starts to slow down and load the prop the esc will apply power to maintain rpm, so you don't need to throttle up much, maybe 2 clicks on the stick.

So if you don't throttle up early you will really lose airspeed.  Mostly in looping elements you actually never need to really come to a full idle, as the esc is essentially braking all the time to maintain the rpm based on your stick position.

In case it doesn’t show up properly, one column is % of output, one column is us output of rx (0 - 2000 us) and last is motor rpm.
