Default losi box

Here is a pic of my box. I was at a race a couple weeks ago and I noticed I had the ugliest box at the pit lane so I had to do something about it. I looked up the local powder coater and here it is. I hve been running this box stock with 2 28c 2 cell lipos and rewired with big wire and soldered it all in with no prob starting even my new grp.

buy a pack of new one's....they are pressed on and you will damage them trying to get them off most likely.....they are cheap like 5$ for the pair then just drill and tap a set screw and install.

I think most of the starter boxes use pressed on pinions. Once you press on a gear and remove it, the gear has lost the holding power. So that's why new gears are needed. Fresh fit basically.

Like Integra said, drill and tap for a set screw for extra security.

Ok I gave up. I re-wired the whole box with wet noodle, soldered right to the contacts, bought some lipos, put some modded 550 motors in it, and it still won't turn over my GRP. I ordered the Ofna twin 775 motors truggy box.

did you do all the normal break-in procedures as well? Like pre heat the engine with heat gun/hair dryer, loosen the glow plug a couple turns, turn the flywheel counter clockwise (viewed from the rear) till almost top dead center, and let the starter box spool up before pushing all the way down with the vehicle?

The GRP engines are tight as hell, just like the Dynamite Platinum XP's. I have 3+ gallons on my Dynamite XP which has lead a hard life so far of nothing but Dirt Oval racing. Ninety percent of the time the engine is WOT. So the other day I thought my starter box battery was dead cause it wouldn't turn over the XP engine. I tried to move the flywheel by hand but it wouldn't budge. So I put the heat gun on her for a few minutes and tried again. Waalah. Success, and fired right up. HUH?!?! Three gallons and it's still that tight was a surprise to me. LOL. I can't remember the ambient temps but I think it was around 60 degrees F. IDK.

Same story for me. I never did try lipo, but did re-wire and go through a few sets of motors. Threw it in the garbage and bought a couple ofna truggy start boxes. They will turn anything over just with a gel cell and stock wiring.

Yea bro did all the normal starting stuff, and it didn't work. Then I walked over to my buddy at the track who has the Ofna box and bumped the truggy once and it fired right up. I'm still keeping the other box for a backup.
Funny thing is that the box did work for the first gallon, but then stopped starting the engine. Just doesn't have the power I need I guess.

im in the process of adapting the losi slide locking mechanism onto my ofna truggy box..i seen it posted on here before...that way i can use one box to start my 8ight T and B 2.0..i hope the longer chasis of the 2.0 truggy still fits on the box! and have a box that is light and will last forever!
