Re: Holding down LiPo's

For this XX and XXT, I cut the sides of the tunnel to the length of the lipo, so the lipo sits flat and has an edge front and back to keep it from sliding. A carbon top brace squeezes it down and keeps it secure.

Re: Losi XX4 Modern Racer build

Plugging along. I'm using MIP aluminum front CVDs. Unfortunately the anodizing was so dark, they basically looked like steel. So I polished them up for some added bling.

I also reluctantly cut open my sealed package of Lunsford XX4 king pins. This was a very hard item for me to find.

Re: Losi XX4 Modern Racer build

I'm a big fan of the Jconcepts finned turnbuckles. These are the slightly bulkier 3.5mm Ti units in black, fitted with Lunsford ends. Lunsford and Jconcepts both make such impressive products. The appearance and finish of Lunsford titanium hardware is better than anything else in the RC market that ...

Re: Losi XX4 Modern Racer build

I wanted to save these 2 new pivot braces if possible. I had this well used Trinity brace that was very ground down on the 2 lower corners. I wish I had taken a before picture. It looked trashed. I spent some time sanding, stripping, and polishing. It turned out pretty good and it should do the job ...

Re: Losi XX4 Modern Racer build

Losi aluminum drives with the beautiful light colored anodizing. I am using Exotek 22-4 hubs. It took a lot of trial and error, but I got the parts to all work together. The drives spin very free with zero slop.

Re: Losi XX4 Modern Racer build

I assembled the shocks from this pile of new parts and used shocks. I'm using XXX threaded bodies with gold shafts. Internal limiters and springs. I may be changing the springs.

Re: Losi XX4 Modern Racer build

What did you do about bearings with those rear hubs? isn't the 22-4 metric? ps: if you end up looking to sell any of that older stuff xx4 let me know, looking to use my xx-4 again and could use some stuff. would be nice to put some threaded shock on it. Thanks. I had to slightly t...

Re: Losi XX4 Modern Racer build

Time for the fun stuff. I am using a Skektrum S6245 servo. It comes with a ridiculously short 2" lead. I was wondering how best to route the wire to the other side of the tunnel when I realized I could go straight through it. I notched 2 small openings the size of the wire. The fit is tight eno...

Re: Losi XX4 Modern Racer build

Some Trinity goodness. Because this chassis isnt cut to allow the motor to sit lower, I couldn't use the motor mount I preferred. I considered cutting the chassis, but am going to hold off for now. I was very happy to find a set of black tunnel plugs. These have gotten quite scarce. I'm starting wit...

Re: Losi XX4 Modern Racer build

I'm using an R1 Wurks super stock esc. In the interest of space and cleanliness, I changed out the stock capacitor for a smaller unit. I mounted it to the side of the esc body and covered it with a 1up Racing cf shelf. I'm utilizing Trinity XXX swaybar mounts to clamp this Trinity XX4 swaybar. I sti...

Re: Losi XX4 Modern Racer build

Electronics are in place. The end result looks pretty simple, but it took a lot of back and forth trying to get everything wired as clean as possible.

I'm currently waiting on a couple small pieces before I can finish the build.

Re: Losi XX4 Modern Racer build

^ RogueIV - Thanks. Cool looking brace you made. I have some carbon fiber 22-4 braces that I'm going to modify and try to make them work.

Re: Losi XX4 Modern Racer build

These are the Exotek 22-4 braces that I cut up to make work on the XX4. I still need to add some stops, and a few other small changes, but they already hold the batteries very secure. I removed the battery decals and wrapped them with faux carbon for looks and some protection.

Re: Losi XX4 Modern Racer build

I cut out and installed this Bittydesign wing. I also modified the stock wing mounts to accept wing washers and screws instead of body clips.

I also finished the rear swaybar links. Just waiting on my servo steering link to arrive.

JC Racing wheels and Schumacher rubber has been installed. Still working on the stance, and a few other things to come. Comments always welcome.
