I use these in all of my R/C cars. It's a cheap and easy way to improve performance and eliminate pesky glitches. At this price, it's practically a must have for every serious R/C hobbyist.
Had purchased this to have on hand in case my slash decided to glitch after upgrading to a Protek servo. Well I ran about 7 packs through without any problems. Tonight my son goes to run it and wouldn't ya know it started glitching. I installed this and problem was solved. So glad I had it around.
bought it as a precaution and it seemed to actulay help. my savox SAV-SA-1231SG in my emaxx feels faster and stronger as well as my futaba S3305 in my hyper10sc feels faster. worth it instead of paying 40$ for a external BEC.
I have 2 high-voltage MKS servos on my Losi 8T. One day I ran the truggy really hard for an hour and the servos shut down....even though I'm running a 7.4 lipo. Plugged the protector in and it smoothed out the voltage perfectly. Never had an issue again. The voltage of the battery stays perfect. I'll never run without one again. Fit perfectly in the receiver box. A must have for any nitro racer.
4700uF rating. Great for High voltage servos to 'store' energy. Novak also makes one too.
Reviewers broadly report that the Spektrum RC Voltage Protector stopped receiver glitching, servo shutdowns, or voltage drops after installation, particularly with high-torque or high-power servos. Several bought it preventively and say it helped or was simply reassuring. One reviewer noted a 4700 microfarad rating, while another said their unit was rated 475, and one reviewer disputed another's figures, so ratings are inconsistently described. A few reviewers found the performance benefit unclear, and one reviewer felt a stock servo performed better in a different vehicle. Several reviews are brief or generic, and one contains promotional text with a retailer link rather than product experience, which lowers confidence in the overall picture.
