From what I’ve seen the 90km/h figures come from people running the cars on dynos, they don’t give an accurate measurement as traction, weight, acceleration, wind resistance ;p don’t have any impact on the speed of a stationary car.
if you want to use your own relays you need to make sure that they will work with the power you are providing, I’m finding 3V relays almost impossible to get easily (without ordering ones from suppliers like tinracers) and expensive.
I’m running 2x AA and 2x AAA and it’s working well for me, USE NI-MH BATTERIES, the highter the mAh the better, Ni-MH batteries porvide more power at once than standard batteries,
I’m looking at rebuilding the PCB using 4Amp Transistors so I can push more current through without using relays.
if there are specific mods you’d like to know about just ask, If I can I’ll let you know what to do (I’m mainly working on geting more from the electronics side of the package (cheaply)) and I’m sure the other guys will be eager to help too, try to ask specific questions, that way you’ll get concise answers.
I’ll be posting more cheapo mods as I get the time, including getting 4 functions from that turbo button you never knew you had 🙂 adding on a turbo boost (without using relays)
Adding extra batteries (like bored tech and myself do) underglow, indicators headlights etc.
