I'm setting up a 50cc plane and could use some help with the electronics.
I have 3- 2600mah li-ion batts, 2- Mpi regulators (1 ACC135 dual, and 1 ACC139), and 3 Mpi 3470 switches. Do the regs go between the battery and switch or between Rx and switch? How about the ignition?
I remember seeing a diagram on this before but can't seem to find it again...

Receiver Setup:
Battery...Switch...Regulator...Receiver

Ignition Setup:
Battery...Switch...Regulator (if no regulator is necessary, go straight to ignition)...Ignition Module

Bottom Line:
Always place a switch between the battery and whatever you are powering down stream. The AR 9100 comes with a soft switch. I threw it away and installed a Fromeco Badger Switch between each battery and its regulator. I did not need a regulator for my ignition module because it was designed to handle 9.6 volts. My three batteries are Fromeco Relions...2600 mah (2s...7.4 v). Everything works great!

Hope this helps,

I also will be using the AR9100 receiver in my almost finished Extra 300... I have used the A123 batteries with
100 % success in two giant scale (30% and 35%), and will use them in the new Extra, 40%.. I will likely not
use the soft switch either. I will use the JR super switches and power the receiver direct without regualtors, as
the AR9100 is designed to do that. A123 batteries I have used have an output of 6.7 volts max, thus eliminating
the need for regulators or a power supply. I usually fly three or four flights per flying session, and have yet to use
50% of the A123's capacity. I may get there with a 40% Extra using eight HiTech 5955s and two HiTech 5645s.
Oh... yes, there will be a regulator on the Ignition power supply..
