Buffer pack/Backup guard

[jimmyhorns]

Curious to know what people are running.

I havent been using these up until now, but as my flying is starting to move up a level im thinking about investing.

I have seen people use 4 cell Nicds or Nimh, and also the scorpion backup guard.

Im running a BEC in all 3 helis this will apply to, and they all run at 6V

Ideas/options most appreciated

Scorpion backup guard would be my recommendation. Its small and relatively inexpensive.

Cheap 210mah nimh of eBay

and you just run that in parallel with your BEC, with a switch for when you want to fly?

Yep but I dont use a switch, i just plug it into the end if a y lead. Here it is on my goblin

great. Will have a look for simlar packs

4.8v, 4 cell nimh Jimmy off ebay. Works perfectly and unlike the Scorpion guard will charge itself when you're flying.

What ESCs are you using James? Be careful if Castle as I believe there's an issue with Castle BECs are products like the BUG.

Huh?.....

ones a castle bec pro, the other is a western robotics, and the last is the built in bec on a kontronic jive 80HV

I know the Jive will be fine, I have two going with buffer packs and some of the guys at the club have been using them for years (I just have the buffer pack plugged into a spare channel and at the moment I don't have switches on them I just plug them in when I fly).

Bec pro is also ok with a buffer but not sure about using it with the backup guard.

Castle built-in BECs apparently don't have a diode, so the BUG apparently can arm the ESC and (albeit weakly) actually power the motor. Castle simply recommend against using the BUG with their built-in BECs.

Ah ok,wont apply then as the CC 80HV is an opto (becless) ESC

Now that you mention that, I'm pretty sure this was the case with a Turnigy ESC with built-in BEC I was using on my 500 when I first got it. I had a CSM Becsafe on it with a buffer pack but it would sometimes try to turn the motor if the buffer pack was connected first.

Interesting!

I have a Talon 90 on my Goblin so putting a small Nimh or BUG into the Rx is not recommended by CC for that ESC?
