After running the Caster buggy for a couple of packs today, I have taken into account the use of a single 4s pack in one tray is overkill, and decided that it is necesary to swap out to dual 2s packs.
I was flipping left and right today, granted I was running on grass but hey, I still think I would highly benefit from dual 2s's
The CG is just way too high
Thanks for who ever gave me that idea :cool:
like i said on youtube you have the machines to build a track, but too many rocks and crap.
what we did on the rough spots early on was to grab old carpet people where throwing away
The thing is, down in the UK, it's raining all the time and we don't get enough sun so the carpet would rot, already considered that idea. I really would love to get something going though. Perhaps I should start thinking of some layouts and go from there
What about an outdoor turf track like this?

After having run a fare few more packs through the caster buggy since my last update. I thought it was only right to continue to note my progress with the kit :)
As of now, I have 2 parts that are broken on the kit, Front right A-arm, which is being held together by a cable tie or two (works great!).
The other part currently broken is the front, inner lower hinge pin brace. Held straight to the chassis by two round tabs, though mine now has 1 so I will need to replace that sometime with an aluminium one from somewhere. Though it will hold up for now.
I was having some problems with the high C of G caused by the battery pack, which was causing the buggy to flip and roll when any throttle was applied when going around a turn.
Since i'm not made of money and can't afford new packs every week, I simply had to make do with what I had. I will post pictures later on tomorrow but I have modded the battery tray to accommodate the large 4s pack. its a tight fit but it isn't too hard to change out packs once you get the nack.
Another problem I ran into which was completely my own fault, was that the battery tray holding my 4s beast, was detached from the chassis when I landed upside down from a jump. The tray is held to the chassis by two m3 screws, which is fine if you are running 2x 2s lipo's but I am obviously not. So the plastic tray couldn't hold the weight and just stripped the threads. This was easily overcome by counter sinking the tray from the top, so I have made myself a notch for a small nut to sit in above the tray, and a bolt through from the other side. This is super strong and will ensure that your tray is safely secured down.
Not a compulsory mod, but if your planning to run this kit on a single 4s, it may be something you wish to consider.
From my experience, what I have found is that, on the side of the battery, the rear wheel has a considerable amount more wear on than the others. Now I know this is obviously due to the heavy battery, but just thought I would mention it.
One other thing I have changed on the buggy, is I changed the shock positioning lower and upper. I moved it to its most upright angle (top out, in towards centre). This has drastically improved the jumping characteristics surprisingly, which is great :)
I still have yet to get down to the track and try it out. Especially now with the new pack layout, it should work really good. I will get some video footage of the buggy at the track, once I get another pack, so it's worth my while when I get there :)
used carpet might be worth a try, some of the cheaper stuff if nylon based , we have some on our track for 2 years through rain and snow and its still there and when it rains its completely submerged
