Does anybody have a diagram/ Setup sugestions for the
AR7100R with Microbeast, using the HV for cyclic as well as the Rev Limiter
I have read in numerious posts that HV should not be run thru microbeast.

I cannot take credit for this drawing as I found it somewhere else and cannot remember where.
This is the way mine is wired You will notice the signal for rudder is the only pin on the tail servo going to the MB. It is getting power from the RX on the 5.2V bus of the AR7100R. The rest is wired per the manual. Of course you still have the signal wire on the 3 wire connect coming from the MB to the RUDD channel on the AR7100R.

So you are running HV cyclic servos thru Microbeast at full 2 cell lipo voltage, with no problem?
Also do you have this setup on a 50 or 90 size nitro?
Thanks

I run a Perfect Regulators Spek-Line between the battery and the AR7100R. This is on a Compass 3d Plus which is a 50 sized heli.

I'm running align DS620 servos on Cyclic. In my past experiences, Align servos don't like 7V in a flybarless setup. They stay even cooler at 5.2V

Not sure what answers you are looking for but, I have approxomately 50+ flights on my Trex 700 with the beastx and 7100R.

My flying consists of FFF, Tic-Tocs, Half Piro-Flips, Sloppy Hurricanes and such.

First 20 flights I was running DS610s on cyclic/DS650 on the tail
Last 30 flights I am running JR8917s on cyclic/DS650 on the tail

All flights have been run at 165hz in set-up menu point "B" (v2), straight 2s lipo with a standard step-down (probably drops input v by .8v) on the tail, and everything is wired per the manual.
I switched to the 8917s because I got a deal on them and wanted to try them out. So far I have not had any problems or failures from either set up.

I was going to split the power wires from my cyclic servos and connect them back to the 7100R while leaving the signal coming from the beastx but I have been too lazy to do it.:oops: It may bite me later but, I'll deal with it then.

I just recieved my new Outrage 9188 tail servo that I am going to install today and get rid of the step-down.

This is how I am setup on my Trex 550e. Works perfectly. Did not want to risk my BLS251 on straight Lithium phosphate 2S.
