LOSI LST XXL Conversion ideas - RC-Monster Forums

My car is all packed, I'm going to the race track today for a few hours to see how well (or how poorly) this LST XXL of mine will handle an 8th scale off road track.

I'm back from the track. Today was an open practice day so I got to run this truck on 6S with a new set of Panther Pythons mounted on TRX dish wheels. These tires give good traction on any kind of track surface, dusty, loamy, blue groove, it doesn't matter, the tires just have great bite and I love them. I didn't have any problems clearing the big jumps. It was even easy to over shoot them farther than the Truggys did. I still had the stock springs on and my diffs were way too stiff. The truck was squirrely and it bottomed out in many places. Other than that, the handling was very good and with yellow springs and lighter lube in the diffs, this truck would be an awesome racer.

The temps after a set of 3S Turnigy 5800 mah were 150 motor, 125 ESC, 110 lipos. The weather was sunny and very humid with no wind and a temperature in the 30 Celsius. Very hot day.

My driving was rusty to say the least, I hadn't been on a track in over a year so I made quite a few mistakes. But that is fine, all those missed landings and hits and cartwheels really tested the durability of the truck. That thing is tough!The only thing that didn't hold up to the abuse was one of the battery boxes. I was very disappointed with that and it put an end to my day prematurely.
There is a huge double immediately followed by a small single. I had to come in at a controlled speed to just make the double and glide through the small single. That is the fast way of doing it. I over shot the double and lawn darted the small single from 12 feet high. One of the battery box wasn't strong enough for the weight of the lipo moving forward and the front of the box completely snapped off.
So I will have to find either a better to mount these boxes or find a stronger alternative.

Here's what I came up with to strengthen my battery boxes. Brackets made of aluminum angle with reinforcements at the corners. I'm thinking of testing this by putting my heaviest lipos in the boxes and dropping the truck on its nose from 16 feet.

Great idea! Let us know how it turns out. If it passes this test, get the truck up to top speed and run it into a brick wall. Then you'll really know that you're good to go.

[btw: the brackets look nice]

Thanks and I'm not dumb enough the run the truck in a brick wall. I was thinking more of jumping it in a wood chipper.

Dropping it on the nose would simulate that jump I missed at the track when I lawn darted in the face of a jump. That's when the battery box broke. If I can recreate that event and the battery boxes survive then I'll know these brackets are good. If not then I'll have to get back to the drawing board.

What's wrong with doing some every other day bash jumps??? Of course, with the all important acid test........ use a camera when you do it

It would probably be more fun to go out and jump the truck trying to land it on the nose instead of just dropping the thing from the top of my backyard deck.

Did you MAKE those brackets??? WOW. I'm impressed. Like... REALLY impressed! How on earth did you make those, dare I ask?

I hope it works, because with all that effort you put into building them, it would be really sad if it didn't. But, ya gotta try in order to know for sure huh?
