Default LiPoly reciever packs/Spektrum

Is anyone using this combo? Do I need to use some type of regulator? I dont want to fry my Spectrum reciever. That would be bad. Any info will be appreciated. Thanks.

Spektrum says the receiver can handle up to 9 Volt, but most servos will have a problem with the 7.4 Volt of a LiPo pack, so yes, you need a regulator, especially one with a low voltage cut off, otherwise your car might go up in flames.

I tried Lipoly last year and even with a regulator I barbecued some KO digital servos.

I ran that combo all summer with no problems. I use the Novak regulator.
Some servos could handle the extra voltage but I did not want to chance it with mine.

By the way, low voltage cut-off has no effect on whether or not a lipo goes up in flames. Excessive voltage during the charging process is where the fire risk is. The voltage cut-off (on-board) would be there to keep the cells from getting too low on voltage. The danger is in the cells inabillity to recharge if taken down to far.

Damn, the price to pay to save a little weight. I will probably go with the pre made one since I don't want to cook something due to it being my fault.

Default VXR Racing products

Guys,

I am using the receiver pack and regulators from VXR Racing. Their products are much lighter and smaller. Check it out at VXR Racing
