Hi everyone,I would like to introduce ourselves we are new to the gravity car racing, and have found this site very useful. This our first year and we are now finishing off our car, the car was built on our college course and has been designed by students and built by students, we hope to enter our first race at the Belchford Downhill Challenge, please check us out on facebook, https://www.facebook.com/NorthamptonCollegeGravityRacing any feedback would be great as this is our first try!

Pete......here`s a top tip...when you calibrate your speedo, tell it you`ve got 10" wheels..should be good for 100mph then !!!

Andy - your speedo sounds like just the thing for our new sidecar - we'll try anything to get more than 50mph out of the thing

Thank you all for your input !!! I have replaced the battery in the current speedo and moved the pick up sensor closer to the wheel magnet... now works up to 58mph now !!!!( found that out last weekend).....maybe measure faster ?......who knows ...

We still have a serviceable and proven sidecar going begging. Phone me on 07967 440946 during working hours if interested.

I've just started looking for a racer, please get in contat if you're selling one, or got any leads....thanks,Landy

We've entered... the prizes sound very tasty!

Hi Catterlinecarties, correct presumption it was just a local village event which we were keen to support. Have just sold the mark 1 cart on this site and we weren't really up for completing the build on mark 2 but we had fantastic fun over the two years of the Haselor event.Then to Stugly, thanks for your interest the material we had collected is as stated 6 wheelchair wheels and hubs including the chassis mounting bosses off the wheelchairs. Photo attached.As you can see the wheel hubs/bearings and stub axles are the core parts, two wheels are 36 spoke and 4 are 28 but with a new machined spoke ring the hubs could be converted to any number of spokes to suit new rims. The existing rims/tyres are all 37- 501 (22" x 1 3/8") and are useable but may not be optimum for side loads, we used 20" wheels on our mark 1 with bolted wheel discs and they were quite strong enough, so you could follow that cheaper route I guess?The stub axles are 12.7mm dia and fit a 30mm long boss, all included as part of the wheelchair chassis's as shown, one pair of bosses are clamp mounted the others are brazed and integral to the uprights.It's a great start to a new project and we spent a lot of time collecting and buying these parts ready to go. I should add that no wheelchair users were injured or harmed during this process!Please login to download attachments.

hi i am also new to the sport and i am also in london. have you made you board ye?. i have been looking for someone to go out luging with if your up for it.

Hello.....not to familiar with what you are selling.....any chance you could confirm wheel size, axle size, axle length & hub length......possibly photos if you have some.....many thanks. Stugly

I'm sorry to hear your event is not longer running - I'm presuming it was the Haselor Soapbox Derby.There are a few races near you though, so you could always complete your build and enter them instead.There's one at Avon Dasset, Hinkley, and of course the magnificent Richard's Castle. Have a look at the map on http://scottishcarties.org.uk/forum/soapboxRacesInUKAndIreland for others near you.

Having developed plans for our mark 2 Gravity Cart we had commenced the material acquisition phase when our event was permanently cancelled.The mark 2 was based on wheelchair stub axles and hubs, using the mounting bosses from the wheelchair frames. This appeared to be the best design route using well made components and enabling the wheel track to be maximised for a given overall width of cart.We now have 3 pairs of stub axles, hubs and mounting bosses for sale. The hubs still have wheelchair spokes, rims and tyres attached. All six sets available for 30.We are near Stratford upon Avon. email: ukgsa@ehale.co.uk.

According to CartieSim it's;Length : 600mTotal drop : 37mAvg gradient: 1 in 16 (6%)Max gradient: 1 in 10 (10%)Typical time : 61 to 64 secondsTwo corners that will probably require moderate braking. Top speed between 40 and 45mph immediately before braking for the big right hander.CartieSim data file attached.Unfortunately I doubt I'll be there. The date is not particularly good for me - the weekend after Cairngorm and Annandale makes it a pretty hard sell to the wife Please login to download attachments.

Nice one! Can't wait to try it out. Looks like about half a mile, with a 60 metre drop, (approx 6% average gradient) assuming the sharp left-hander going into the village will be part of the track.Should be quick
