Over-Volting Electric motors

update.
This had major traction issues that may have discouraged them about the idea entirely
The obstacles will be disposable water cups, and gentle humps.
Im absolutely gutted that i wont be able to directly help on this one
Bigger wheels will improve traction by slowing the initial acceleration, improve chances of overcoming obstacles and give greater top speed.This had major traction issues that may have discouraged them about the idea entirely

Consider wheels large enough that it could run either way up (and pray it doesn't flip the 'wrong way' and return to the start line

Kids arent allowed to bring them home so im reduced to having a glorified Consultancy role.
also the teacher has moved the goalposts and they now only have x2 Double AA battery packs giving 6 wonderful volts.
Ive given them a lesson a series vs parallel wiring telling them volts are all that matter here. more volts = more rpm etc
Ive also demonstrated to them what i mean about elastic band drive by using some old lego and the same construction tools that they have at school... i.e nothing! + pva glue

Do you think their teacher reads PH? Kids arent allowed to bring them home so im reduced to having a glorified Consultancy role.

Use the elastic bands to drive a fan to get the car up to big gear speed....
Bigger wheels would seem like a very good idea.
Daughter won!! W0000!!!
by the largest of margins too.. as nobody elses buggys were able to move under their own power
my sons was too heavy so the drivesystem just endlessly slipped.
Daughter listen to me by making it light, and keeping it simple, and also used the mc'd straws as axle housings.
she elected not to use the rubber band drive system
maybe we can use the microbit on the next upgrade

So the combined efforts of a cross section of 30 electrical engineers / mechanical engineers and slot car fanatics managed to beat a classroom or two of school kids.by the largest of margins too.. as nobody elses buggys were able to move under their own power

We all deserve a trophy.
I assume you will be deputising for her down the boozer later?

heres my Sons team's effort:
RWD, heavy to plough through obstacles without being knocked off course
here's my daughters team's effort:
FWD, light 'to go fast quick'
they tell me they both created a bigger 'gear' using an extra wooden wheel to go onto the motor, but they ran out of time to fit it as the rest of their respective teams were useless and left them to do all the work. lol
As you say, im trying to instill into them a willingness to 'DO' and at least have a proper go if its a task that's far too difficult
I gave my daughter full control of the remote all weekend and unlimited veto's on netflix choices as a winners reward
I \ we all regretted it within 5 mins, but im hoping the gesture was appreciated
