I dont think it is 1/24" because its smaller than any other 1/24 model and or 1/25 even. Its more like 1/28-1/32 scale - well; for width anyways.
I'm finding that for extreme hill climbing I am needing a low, low center of gravity, and thus I added bbs to all 4 tires.
32 up front and 20 out back - makes her heavy and strain the battery and motor more, but, it keeps it planted. I also mount stock batt to front on top of servo which helps, but I could use more weight.
I built this mountain out of scrap foam parts and it looks like hell but is challenging and works good for training. Some of the angles are steep and I added in chunks to make it more difficult.
I need to find some heavier 1-2S lipos that will fit up front, yet wont interfer with articulation or suspension.
My set up on a 2S is plenty of power - probably too much lol. The stock battery seems a little fatigued and underpowered with extra weight but, delivers that low end slow torque better than 2S.
I have yet to try a 1S lipo yet. I have a bunch, just none that are really heavy enough for hull climbing.
Have you tried out a 1S lipo?
ps
I'll check crappy tire for those springs
?? no idear 1/24? lol for weight i did one wrap of 3/16 lead rope fishing weight in each front and 4 wraps of solder in the back works good, and i have the stock springs on front and some beefy springs that were exactly right size, found em in the hardware section of canadian tire......check it out
