Kendall Bennett from Amainhobbies.com just recently built a Kyosho ZX-5 with a brushless setup. He ran a few IB3800 packs in the car and then slappedin one of the Team Orion 4800mah LiPo packs. The Team Orion pack is in a case that mimmicks the size of a 6-cell stick pack. BUT, it's less than half the weight. The 6-cell packs are 7.2 volts where as the LiPo is 7.4 volts.
With the lighter pack, he said the car is Ballistic!
It's much faster off the line and has much more top speed. It also lasts for well over 20 minutes. He thought it might be too powerful for the track after he ran it outside the shop for a bit on the pavement. He said if he nailed the throttle the car would spin out violently. But then he ran the car on an off-road US style indoor track and said it handled better, jumped better and was quite controllable (after driving it for a few laps and getting used to it). Another benefit was that he didn't break anything all day since the car was so much lighter. His only complaint was the other guys racing were all jealous and wanted one real bad ....LOL
I plan on buying one as soon as he gets them back in stock to run in my ZX-5 with Novak GTB 6.5 setup. At my llocal off-road outdoor track, they have a small turnout with 1/10th scale gas trucks. They just clump all the 1/10th scales together whether it's gas, electric, buggy or truck. Last year my son ran his Matt Francis 2 against the gas trucks. If the mains were longer than 10 minutes, it killed us. This year he's going to run my ZX-5 with the brushless and LiPo. I suspect after he starts handing all the gas trucks there a$$, they'll try to ban him ....HAHAHA
I'm hoping everyone goes out and picks up a ZX-5 or another 4WD electric.
