Hello, I’m fairly new to scalextric and slot car racing in general and I’ve noticed some differences in how power is sent to the cars when using the analog controller vs. the SparkPlug app. So I have a mix of cars. A couple formula e (so far these are the smoothest running cars), British touring cars (sometimes they just stop on the track), and a few old/used scalextric sport f1 cars (not as quick as the newer cars, but less problematic than the touring cars). Sometimes while using the analog controller, a car will just stop or stutter on the track. Usually when I’m reducing power around a corner. When I gently squeeze on the trigger to accelerate, sometimes the car won’t move and I’ll keep squeezing until the car decides to take off like a rocket ship. I have two controllers and they both behave this way. Like there’s a dead zone while making small adjustments in finger pressure. Just wondering if that’s how those basic controllers behave or if I just have a set of bunk controllers. Since I’m new at this and wouldn’t know right off the bat. My Formula E set came with SparkPlug dongles, and pretty much all the cars drive smoothly while using the app, but I really don’t enjoy using the touch screen to control my cars. So, should I try another set of analog controllers? Should I buy an ARC PRO power source if I want to enjoy that smooth and constant power delivery? (I assume that while SparkPlug and arc pro are incompatible, they’re still delivering a digital signal to the track?) Thank you for any insight and help that you may offer, and for your time in reading all of this.
