“I bought a new FCU because one of mine broke. The negative wire from the JST pigtail broke. I attemped to solder which was dumb. So I bought a new one. I guess Polar Star realizd the routing of their wires had a weak point and they have since re routed. It seems much more rigid and I hope it lasts longer.”

“The polar star fcu v3 is a perfect addition to your hpa set up due to have the modularity of changing anything you need in the board. It’s has a screen in the actual board for easy menu selection that really is nice.”

“I had the stock r2 polar star board. Messed with the settings just a little bit but one day I was turning my full auto to 2rd burst for a "faster trigger finger" LOL. But it sparked and then kinda of blew up LMAO just thinking about it. I got this one having a tournament in a few days put my setting on it and ran it with no problems. JUST DON'T MESS WITH YOUR FCU MORE THAN YOU NEED TO.”

“Just a standard fcu. Ordered on a Sunday and got it by Wednesday. Fast shipping which was great. Had to purchase due to my original one had torn wire on the board. Little flimsy so be careful.”
