Mojave Mojave EXB Speed Run Build Sheet

Cool stuff buddy @jondilly1974, it can indeed help and prolong the lifetime of GRP. I haven't tried kevlar string, but so far the fishing wire is holding up. Nasty with the finger too when you are pulling it a bit tight hehe be careful not to get paper cuts

My hands are pretty tough from work, so they don’t cut easily, but still that fishing line is sharp Going to test out the tires today. I hope they hold up. The glue has cured for days now.

Well the glue didn’t hold the fishing braid on the tires very long. Fronts held longer than the rears, but still blew a rear at 125mph. Pretty nasty crash. Lipos went sliding down the road. ABS skid is trashed. Body mounts ripped apart. Missing a lipo strap. Time to rebuild.

It could have been my application wasn’t as good. I got it wrapped around really well and glued evenly. But the IC-2000 glue just burned off very quickly and the wrap came off after that obviously. Maybe my treads weren’t deep enough. I had used these GRPs for drag racing before so they had been worn some. Either way, I’m moving to foams most likely. It was always the plan and going to be time now.

This is just like running the bigger Felony Hoons. Anything bigger than 100 mm is gonna have issues with ballooning at the speed you run. Everyone who's commented on my Facebook posts says foams are the only way to go when you get up into the 120 + catagory. Even though many have taken the regular GRP's into that territory, they all say it's just a receipe waiting for disaster.

Yep I have been getting the same from the wisemen here. I even knew ahead of building this truck that while they look good, they weren’t going to hold up past a certain point. Was hoping wrapping would push that goal post a little further, but either way, it’s time for foams. Looking now to find something close to the same size, but I’m not sure they exist. I am also reaching out to Gone Bananas to see if he can foam swap the 1:5 GRPs. Either way, foams will be used from here on out. I’m done with GRPs.

Okay, make a list of what you got. Notorious J will happily take those GRP's off your hands, for the right price of course

Here we go again….

Been there, but you handle it way better than I do....
That sigh at 15:08 ("I love this hobby, but in this moment I want to quit")

Anxious to see how the voltage sag looks with 12Ah. Hopefully if nothing else some good data will come from this outing.
127 from the YoWoo's was pretty good also.

Damn that sucks brother, hate to see bad carnage like that! Hopefully the foams will hold up and do a lot better for ya.

Here are the logs in order of passes

Ouch! hate to see a good morning turn sour. Carnage was minimal at least.

They may go, we'll see, I'm hoping not. That my friend is the voice of a true thrill seeker. Too bad you didn't have a gps on that battery pack. World record speed for sure.

Looks like it was around 3v better than other runs at similar speeds.

Roughly 27 v an dropping fast.. I would expect you could reduce the gear a little given the extra RPMs? (food for thought)

Here is the mouse over the spot where you marked... got down to 25.8v before the packs probably came unplugged. Next run will be with smaller size foams tires, so it will be geared down anyways.

GRP 1:5 118mm 150mph

Sweep Racing Max Forward 105mm 134mph

 

[jondilly1974]

Here we go again! Got the sheet of ABS and I’m ready to get this thing built again.

 

[jondilly1974]

More progress today. Waiting on tires now…

 

[TriggerHappy]

Man that looks awesum

 

[jondilly1974]

Oh and I added two more lipo straps. Hopefully the lipo eject button is held in check this time
