Try using 60cm shell panels instead of CF extenders.
I think SM is a pretty cool guy, eh builds unicycle-bots and doesn't afraid of anything
The chassis needs more armor, especially with what it has now. Scorpion is right, you don't need the DSL bars: the main extender is safe where it is already. Get rid of the bars and try to get at least titanium 5 on it.
Could you make a video on how it works?
Here, have one of the first DSL bots I ever made. I made this little number ages ago when trying to make a walker. The end result was this,(Image removed from quote.)(Image removed from quote.)It actually moves surprisingly well. It has a tail so it can reverse. I think I made that wretched extenderwork so I could align the pistons easier.
