look at all the m12s on the stand.

He switched to airtronics a month or two ago from what I read. If you look back a few months or so look at at his set up sheet and some say ds1015.

OMG hasn't anyone told him you can't use birdcage bullets?

Nice. I have always been partial to airtronics...well until I blew up their servo 2x time less than 2 heats. Now I run cheapest servo I could find, lol. And it lives. even my scte 4x4 could not kill it. Not like i didnt try, lol.

He will lose worlds for sure with just that little fact. Wait, didnt Ty win the worlds warmup in 4x4 with skinny bore shocks? so wtf do we know, lol. All urban RC myths need to be rethought.

going to replace my front hinge pins and a-arms. was thinking of just going stock AE steel and either the carbon arms or regular plastic in 13.5 and 17.5. Looked at the Lunsford hinge pins but I have not had a lot of luck with their stuff for the b4.2 expensive and just does work real easy. thinking about popping on those avid stand-offs now since I am in rebuild mode a little.

Somebody please correct me if I'm wrong but I believe Futaba makes the XP servo's .....:batman:

Ace does

:nod:

A certain pro driver lost a nationals A main a couple years back due to those birdcage style connectors getting hot and unsoldering at the battery plug... True story ;)

lol, I am sure. I use solids because lipo fires scare me. never lost a worlds because of it though, lol.

I use the stock steel pins, they work, if I bend one everyone sells em. I switched to the carbon arms and C-hubs, they seem to make the front end a lot tighter and have less flex.

picked up my b4.2 today gonna start the build tommarow!

I mis-ordered mine and had to RMA & send back a perfectly good 4.1 to re-order the 4.2. Hope this is no indication of the rest of my future in RC.
