lipo with/without regulator ?
I want to know if anyone is running a futaba reciever without a 6.0 volt regulator using a 7.4 lipo reciver pack. will they hold up to the higher volts.
Thanks Ken

I had the same question so I emailed futuba and was advised by product support lead tech John G futuba does not recommend the use of lipo batteries with there recievers

To note... I initially screwed up when plugging my 2cell pack into my KO302F RX... didn't last long (1mn max) as I quickly spotted I had screwed up the wiring, but during that minute it worked perfectly.
I heard the spektrum rx'es are spec'ed all the way up to 9V.
anyways - play it safe, and use a $20 regulator on your $1500+ toy

i got the same answer from futaba, but i wanted to get the most out of my hitech 7955's. most of the other radio'swill handle the higher volts.

Man I'm running a spektrum dx3r , hi-tec 7955 with a 1500 mah 7.4 v 2s lipo and I am at wits end, the damn thing will run flawless at one race and do nothing but glitch at the next race. It glitches in the exact same 4 spots on the track. I guess I'll have to put the damn regulator back in it unless someone has a better idea. This is suppose to work without a regulator.

No, I was not but someone at the track told me if there was enough excess wire inside the batt/rx box , to form a loop that it would cause it to glitch....so I used all of the length in the ant. tube and the problem is still there. It happens in the exact same spots on our track.It seems that if I re-bind the problem goes away for about 2 min. and then slowly comes back.Thanks for the reply! I have thought about trying to some how drain off some voltage to about 5.5 volts and see if the glitching dissappears but i do not know how to effectively/quickly drain off some voltage without damaging the lipo.

DO NOT Discharge the lipo to 5.5v WHAT EVER You do. BIG NONO

I had the thing running flawlessly with an mpi regulator and started trying sh-t to make it a cleaner looking batt. box. You know they say if it aint broke don't fix it. I just wish I could run un-regulated, I guess I'll have to put the regulator back in there. Thanks!!!
