My slot car hobby has been on almost a 15 year hiatus, so I must admit I haven't kept up...I used to race a huge four lane Scalextric classic layout, but with limited space and kids coming along has been sitting in the attic. I have used both the old Scalextric classic throttles and the Sport dito (with converter track pieces). Both with satisfying results. When I finally brought down the boxes and built a small track i the living room I wanted to add something to make that small track more entertaining, so I got myself an analog SCX Pit Box (for the thrill of refilling fuel).... And now to the actual problem...It is complete rubbish, at least for the moment. The throttles that came along are terrible. The triggers are so sensitive/non-compliant, and the cars go unevenly and jumpy around the track. I have a wide variety of cars, mostly Scalextric spanning from the 60's to now, and the majority of the cars are almost undriveable with the new throttles. This has not been a problem before, although the cars as you all know have their own characteristics. I need some advice here..Is it the Pit Box/power pack itself that is causing this or is it the throttles? Is it common knowledge that the SCX throttles have less resistance, if that is the case? Are there any known compatibility issues when using SCX with Scalextric, power pack or anything like that? Would it be a good idea to change connectors on some of my other hand throttles to use with the Pit Box? Or do I have to go pro and buy expensive throttles like Parma to solve this? Sorry for being long winded.
