Problems with Avant Slot cars on Scalextric Digital in Analog mode

I was thinking the opposite, that it was delivering too much power (I am not into the electrical stuff and it doesnt make sense to me, but... it was a thought). I have two power supplies connected to the advanced powerbase, both delivering 15v with 4 amp each. I also run NSR Moslers on it with the Shark 25K rpm engines (and I agree, with 15v it´s way too much power on a plastic Scalextric track, I hardly can push the throthle to the half, good thing you can adjust the throthle levels on the 7042) without any problems what so ever, they run smoothly all over the track and goes like lightning.

I think Riko is on to something. It´s something with the engines that simply does not like the Scalextric digital layout. I switched to the old powerbase (the analog sports powerbase and adapters), and the cars ran very smoothly. Tho as you said, the powerbase did not deliver enough power to make it fun to drive. But the "jumping" behaviour vanished directly.

I will try to put a different engine into one of them and see if it runs more smoothly, it´s not a huge investment. I am more curious and wanting to know for the future if i should avoid Avant cars or not. Maybe it´s just a series of motors that has this problem...? I could not see any markings on the engines, but the information I have is that it´s exactly what you said, that it´s a 27k rpm "Hurricane" orange engine in them. Maybe they simply has issues with the advanced powerbase or the voltage.

Hi all,

The problem is solved, but I only have an IDEA what the solution was.

Simply put, I took the time today to take the cars down into pieces.
I removed the wiring and rewired and resolded the engines with Slot-IT cabling.
Then I put the car on the setup block and remounted the motor block and adjusted all (damn, it has lots) of the screws.
The pick-up got new brading (NSR).

After this, all the car runs indeed like a Hurricane. My theory is that it was a combination of problems, mostly related to tuning the screws. I think the power of the Advanced Powerbase (15v/4amp) in relation to a damn strong engine with huge torque created some jumping of the car or the engine blocks and making the car simply loose the power.

Or... who knows, maybe it was crappy solding or wiring problems.

They are still quite hard to control on the track since they are so strong and has less magnetic traction, but they are amazingly fun to drive and I think I will have a blast running these Avant cars together with my friends. They will not get the fastest lap times, but they will provide a fun race that takes some concentration and control to win.

Thanks all for your ideas and input. So nice to have a great community like this to batter out ideas with when you run into trouble.
