I am in the process of setting up a 50cc Yak. I already use a BattShare on an Ultimate and love it!! Anyway on to my question. I am thinking the power expander may be overkill on this airplane. But I really want to use the pin&flag switch, so is the power expander really needed or can I come out of the SuperReg and straight into the receiver. If I can come out of the SuperReg into the reciever will I have to change connectors on the SuperReg (adapter or something).

LION1 -
>SuperReg - Reciver
LION2 -

Will this work or do you feel the power expander is a much better option.

Also will the Triton Charger work on common ground systems?

and finally, what connectors do I need on my LION batteries to connect to the SuperReg?

Sorry for the silly questions but I am trying to make the right decision.

Thanks
John

Hi John,
These are all good questions. I use a SuperReg on my 50cc plane without a PowerExpander at the moment. You will need to make up some adapters to mate with the Deans Ultraplugs on the SuperReg and standard male R/C connectors on your receiver. I would recommend using two. You will need two Deans Ultra males and two male pigtails for the receiver.

I really do not know if the Triton can handle common ground but I think I may have heard it will NOT. I am not positive though.

You will need Deans Ultraplug females on your batteries.

Let me know if you have other questions.

It seems that the general idea is to only use a Batshare or super -reg on a 50cc plane. While the super reg and power expander used together is typically used for 30% and above.
Is this to save weight ?? I am not really sure.. Also with the super-reg, using LI-Ion batteries in a redundancy setup, can the batteries plug directly into the super -reg, ( not using any switches on the battery side) and by using a single switch connected directly to the super -reg ( probably a flag pin arrangement) would the single swith then be capable of turning the batteries on & off.
So all i would need for my set up would be 2x Li-Ion batteries-connected directly to the super -reg, single switch, 2x output from the super -reg feeding my RX, How does that sound??

thanks

Hi Dave,
There are benefits to using a PowerExpander in a 50cc plane. The extra filtering and buffering the PowerExpander does will help eliminate spurious noise. It is not really necessary to use a PowerExpander in a 50cc for power distribution although it will provide a small benefit over going throught the receiver. Some people would rather save the weight, although its is only 1.8oz. Some people wish to save the cost of a PowerExpander.

If you use one of our failsafe switch packages you would connect the batteries straight to the SuperReg. The failsafe switch turns the regulator off there by turning off both batteries. When using any failsafe switch you still have a very minimal draw on the batteries when off though. For the SuperReg and two batteries it is about 5mAH/Day out of each battery.
