Has anyone else had issues with driveshafts on the smt10? Everytime my wife and I take them out the driveshafts drop out of them leaving her with front wheel drive and me dead in the water. We've twisted or broken every splined slip centers that came in the kits. Ordered some aluminum ones today so I hope they will work better than the stock plastic ones. Shout out to horizon hobbies as I contacted them about the busted axle on mine and they sent the replacement parts. Great company and customer service.
