I am a bit of a novice and have no where near the experience you guys have but have enjoyed working out what i have, realising what I have isnt what I thought I had and going from there...which means rebuilding my cars a few times!
So the first Yoke I had and bought about 24 years ago is a YZ870c, I took it out of the box after 20 years (stupid me forgot to take the batteries out but luckily there was no damage) and what you see it pretty much what I packed away all those years ago...I did give it a bit of a clean but didn't really over haul it (but I will ) and only really run it on the road.
Bought a new shell and undertray from TBG and was slightly pissed that it didn't quite fit that well...
SO out of the box after a quick clean came this...( I did buy a new motor mount but the fit was a little too tight for this car so I whacked it a different one)...a little bit of glue on the chassis which I managed to get of later..(after I learnt how from you guys) and this was the original shell and wing...which I had tried to get the paint off for obvious reasons...! excuse the hinge pin it was the only spare I had after the original was bent...+ it was for a pavidis ( I know now) and didn't know it would be too long then as I new nothing about the cars... Then with the new shell and some new JC racing wheels (thanks to listening to one of stickboy007's vids..) it looked like this
and now with a coat of paint (again inspired by stickboy...sorry

enjoy.......
