Popular Post tomr Posted March 22, 2021 Popular Post Share Posted March 22, 2021 I thought I’d have a go at making the Jumpshot go fast , nothing to serious but whilst I’m searching eBay and places for a decent speed project this will fill the gap . I have a few things on order , mainly a body and gearing options, hopefully they’ll be here for the weekend so I can get cracking 👍 I’m running a 4000kv motor with a 3s battery, not sure on the gearing yet I’ll have to see what I can make fit when they turn up . 5 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted March 22, 2021 Share Posted March 22, 2021 good luck with this, i would think 60mph is in there, not sure how much more, long term what do you fancy for a speed runner, say, 100mph plus car 1 Quote Link to comment Share on other sites More sharing options...

Not sure what I fancy mate, I don’t trust my driving for anywhere with curbs so it will have to be something that I can run in the car park I use, I feel something like a Limitless would be a bit of a waste unless I can find a bigger area . At the min Ive got my eye on a couple of nice used 1/10 race chassis’s and a 1/8 buggy . Edited March 22, 2021 by tomr 1 Quote Link to comment Share on other sites More sharing options...
Lone-wolf Posted March 23, 2021 Share Posted March 23, 2021 see if there are any big retail parks or industrial estates near you to run at, and dont be worried about curbs, once you get a car that handles well and tracks straight its all good Quote Link to comment Share on other sites More sharing options...

The 28t pinion did 50mph on 2s, going for 3s this weekend 👍 2 Quote Link to comment Share on other sites More sharing options...
tomr Posted March 25, 2021 Author Share Posted March 25, 2021 New body and 130a esc fitted and spur gears are here 👍 Pretty much ready for a Saturday morning speed run on 3s with 40/81 gearing . Test fitted a 41t pinion with 69t spur which fits great and leaves plenty of room for a bigger pinion (52-53t) if I can find any Just a cheapo body but it was painted and uncut so I could leave the wheel arches in . 1 1 Quote Link to comment Share on other sites More sharing options...

Whats with the burrs around the holes, did you lighten it or did it come like that? What body is that? Thank you. Looking forward to seeing it run!

Looking forward to seeing it run! Im hoping for over 60mph 👍 The pinion is a 48dp from eBay ,don’t know what’s going on with those burrs but the teeth look fine . Just found Team Corally do up to a 50t In 48dp The body is an eBay job I can give you a link if you want but it’s super thin , I’m expecting it to explode on the first roll over .Definitely needs reinforcing. 2 Quote Link to comment Share on other sites More sharing options...
Redback Posted March 25, 2021 Share Posted March 25, 2021 (edited) Good luck sir! I hope it all goes well, i find with my 4wd buggies due to the height they like to skate around lots, some extra weight up front and down low might help if you find it uncontrollable, you have the power there. Also smaller wheels might make it slower but will lower the center of gravity by lots and help it hold the line i feel, as you have a big truck get it as low as possible then stop the front from going above the back, this will help stopping it flipping over from catching the wind. Hard to say from the camera angle but do you have 3cm or about 1inch ground clearance? Can you bring it down even lower, can you run 1/10 road tires or scale tires hows it feel / run?

Lone-wolf Posted March 25, 2021 Share Posted March 25, 2021 wow that looks great, and with the esc and gearing its gonna rip the track a new one mate, best of luck with it 1 Quote Link to comment Share on other sites More sharing options...
tomr Posted March 25, 2021 Author Share Posted March 25, 2021 (edited) @Redback Ive limited the shocks so the ride height Is currently 15mm front and 23mm rear . From a 2s 50mph run it ran great, super smooth . I could run 1/10 wheels , I’d never thought of that.It would drop the ride height down lovely. Thanks for the tips , this is all good advice for me ....keep it coming 🙂 Edited March 26, 2021 by tomr Quote Link to comment Share on other sites More sharing options...

Popular Post tomr Posted March 27, 2021 Author Popular Post Share Posted March 27, 2021 This morning’s run went great the Jumpshot ran better than I’d hoped .I really wanted to run again with higher gearing but rain has stopped play . Thanks to all that wished me luck 👍 I think I’m going to push this truck as far as I dare 😁 This is on 3s with 40/81 gearing (I’ve now fitted 40/69 ) 6 Quote Link to comment Share on other sites More sharing options...
