Wrighty8766 Posted October 28, 2015 Share Posted October 28, 2015 (edited) Been building this for a good few months now, the aim of the project is to hopefully break the 130mph barrier, I may be setting my goal a little high there but only time will tell it originally started life as a roller bought off here for a small fee of £20 including fees and shipping, I stripped the whole thing down to have a good look at it and it turned out I only used some of the gearbox parts, the rear shocks and a few nuts and bolts from here and there...all the other bits were bought new As per usual I don't have any photos of the progress, just this one of the nearly finished build from a few weeks ago As it stands it's still not ready for the road, I need to lower it about 20mm up front and 25mm on the rear. Also I need to strip down and rebuild the gearbox using the hot racing hardened gear set I have bought. Would you believe that this comes with puny little plastic gears as standard should be an all metal trans out of the box in my opinion once I have fitted the hardened gears I need to lock it into 2nd and then I can start some testing to see how it handles etc Edited October 28, 2015 by Wrighty8766 Link to comment Share on other sites More sharing options...

sean-vrs Posted October 28, 2015 Share Posted October 28, 2015 I'm just getting into speed myself, I'm hoping for 120 mph out of the xo1 and 85+ out of the funny car.... I'm just hoping it dosnt get too exspensive!! Link to comment Share on other sites More sharing options...
Wrighty8766 Posted October 28, 2015 Author Share Posted October 28, 2015 With great speed comes greater bills unfortunately, once you start pushing the limit every mph costs more and more Link to comment Share on other sites More sharing options...
-BEZ- Posted October 28, 2015 Share Posted October 28, 2015 (edited) Good to see more people with the speed bug! Don't rely on GPS speeds as they can be wildly inaccurate. 130Mph is a lot to ask from something that is as aerodnamic as a brick. Set a realistic goal of breaking the 100mph mark (its A LOT harder than you may think) I personally think you wont get much more than 120Mph at an absolute push. There are many hidden challenges that await you but the fun part is over coming each obstacle as you come across it. Keep up the hard work and I look forward to seeing it run though some timing traps at ROSSA. Edited October 28, 2015 by -BEZ- Link to comment Share on other sites More sharing options...

-BEZ- Posted October 29, 2015 Share Posted October 29, 2015 I beg to differ. GPS is fine if you have loads of distance to cover, but for RC its pretty crap. They will do as a tuning guide but normally a fair bit off what you will register on a speed trap.Enjoy the build but don't get frustrated and quit if you don't find it as simple as you think it will be 1 Link to comment Share on other sites More sharing options...
Wrighty8766 Posted October 30, 2015 Author Share Posted October 30, 2015 Enjoy the build but don't get frustrated and quit if you don't find it as simple as you think it will be I just have a few more things I need to finish off and then I'll be ready to start with the test runs, I have gearing running from 25/40 all the way down to 44/31, the main thing I need to sort is a front splitter of some description Link to comment Share on other sites More sharing options...

Wrighty8766 Posted October 31, 2015 Author Share Posted October 31, 2015 I have seen a few people in Australia with these kind of things, they are getting into the mid 120mph range so I'm guessing that these help Sent from my iPhone using TapatalkThat don't look too kind on the eye but if it works then who cares Link to comment Share on other sites More sharing options...
Wrighty8766 Posted November 10, 2015 Author Share Posted November 10, 2015 Got the hardened gears ready to fit tonight, 2nd gear is locked using the drill and pin method, I drilled it out with a 2.5mm drill bit then used a screw shaft I found off my old rustler, worked perfectly I have filled the diff with some 100k oil, hopefully will stop one side diffing out at high speed and blowing a tyreSent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Wrighty8766 Posted November 12, 2015 Author Share Posted November 12, 2015 Well, just the extra weight to add to the front and chuck the esc in and she will be ready for testing The front is lowered down to about 10mm off the floor and I have left the rear standard, hopefully this should add a fair bit of downward force during a run!I also finished the rebuild of my hyper 7 tonight here are some picsSent from my iPhone using Tapatalk 1 Link to comment Share on other sites More sharing options...
Wrighty8766 Posted December 5, 2015 Author Share Posted December 5, 2015 While the crappy winter weather is closing in I think I will have to invest a small amount on making sure this stays planted to the ground during a run, I was going to make a front bumper weight but I saw this on eBay and couldn't resist 1 Link to comment Share on other sites More sharing options...
Wrighty8766 Posted December 6, 2015 Author Share Posted December 6, 2015 Looking at the description on eBay this weighs roughly 1lb 4oz which is around 567g, should work a treat with it being right on the nose also it is primered ready to paint in whatever colour I want Link to comment Share on other sites More sharing options...

Wrighty8766 Posted December 6, 2015 Author Share Posted December 6, 2015 No travel at all? Would that not leave a bumpy ride? I have lowered the front and firmed them up a bit but I could get some revo springs to make them near solid Link to comment Share on other sites More sharing options...
Wrighty8766 Posted December 6, 2015 Author Share Posted December 6, 2015 full set of brand new revo 3.3 springs for £4.50 with free postage, I can't say no to that should be here Tuesday Link to comment Share on other sites More sharing options...
