010 tether car

Cross drilled and vented? It won't help your tether car go any faster Or stop sooner

Just kidding....I couldn't help myself.

true...
but hopefully will look better than a flat plate

Dont get me thinking it hurts. I,ve never considered a tether car or ever seen one. The only slot cars I ever owned were scalextric. Seeing those pics has got me thinking. Three planes to complete first though.

ebeneezer

just talk to dizzy... he will tell you there is nothing wrong with "just one more" project...(you have already seen then thread)

cheers

I now know, one compled project out in the field, is worth ten in the workshop.

So you have a disc and some cable woohoo nearly time to
Let her rip eh ado starting to get excited about running your car it's gonna fly (well hopefully not ) but u see what I'm getting at
Go on ebeneezer get building a tether the more the merrier lets get loads of them running and start some kind of speed /lap race going all over the world have to agree on a line length though
What length were u thinking ado ???

i was planning to start with 3.182m from pivot to centerline of car.
that gives 20m/lap
5lap = 100m
50 = 1Km
makes speed calculations easy.

if it looks like it is all getting too fast letting it out to 3.97m
25m/lap
4lap/100m

the shorter line should be ok,
and also makes it easier to find a smooth piece of concrete/tarmac/asphalt

Either sound good to me like the way you have done the radius so as to easily calculate circumference therefore speed nice touch that can't wait to find out how it goes and also how the friction on the gears holds up should be perfect me thinks as slotty motors go from 15k all the way up to about 25k last time I looked so don't honk you will have any trouble there like the way you can tune the gearing to useful Rpm's that's what mine is sadly lacking but the next one is gonna be along the same lines as yours I think all good fun everyone at work ( mechanics ) said it couldn't be done on such a small scale when I first started this project have proved them wrong now hahahahaha never underestimate a persistent modeller

Any updates have you run it up yet ??

not yet dizzy

boss at work goes away wed night for two weeks

will be in there thursday to make the tether pole
(i am off work with broken collar bone at the moment)


a.

Any updates me ol chum got it spinning yet ? How did the tether pole go ?

sorry

been slack... well actually been away for a few days

all going well... this week

a

finally got around to making the tether.

front disc off 2012 ford falcon gt.
machined a bearing housing and arm(adjustable for height)

made the tether line from SIG braided steel control line wire
length 3.18m center to between chassis rails, giving 20M/lap

went for first test this morning before it got too hot.

need to do some repairs and mods.
stripped crown wheel, lost grub screw from pinion.
chewed cable(twice) it want to backflip on takeoff, when tuned close to ideal.

onboard igniter broke loose, meaning i had to hand launch with engine running(no push start), causing some of the above problems.

so....
only got a 2 very short vids(need an assistant) of when it was running rich, and when it stripped the crown wheel

~1.4sec/lap=50kph

and you can actually hear the crunch as the crwown wheel strips... about 0.03 sec
cheers

I like the rubber stripes it leaves on the pavement. At least you got it out there. My cameraman is a tripod.

Hey ado celebration time had its first run out then ok some teething problems but u made it bet your pulse was racing too I'm sure you'll get it running sweet as soon am liking your tether base and setup very swish get the spanners out I need more vids

Just found this thread and it's reminded me that I have one of these.

Unbuilt somewhere.

Hey bud how ya doin
Saw the vid got any more yet tried mine couple of days ago had tyre issues ie it flew off again
Oh well plenty more will have to get a vid was just too excited about it looks good less is more with mine where the engineering you have put into yours again is amazing
Need to see
More .... More ..... More .....more
