New Build B4 FT blues and a question

[lucidcreation]

Hi Peeps,

I've been spending the Xmas break building my nice shiney B4 FT. I put a decent package together, but cheaped out on the 27mhz TX (stupid...).

Anyway all built went for the grand switch on after ESC setup and the thing went mental, wheel spinning across living room and burning the living room carpet much to my girlfriends joy (!!!). I've since sent the radio gear back to the shop and upgraded to a 2.4ghz setup which I'm installing this weekend

This did the trick in terms running the diff in (I think??). It seemed to be ok before this little episode with the opposite wheel turning in a different direction quite easily, but afterwards both rear wheels seemed locked together. I tried loosen the thrust bolt, tighten it, nothing.....What would have caused this?

Well putting my few days worth of knowledge together I decided it might be that I just needed to tighten the bolt even more. This then spanned it!



I have ordered another 2 t-nuts and thrust bolts. Only problem is I really don't have a clue how tight this thing should be now. I've read the famous "when you feel the spring completely compressed loosen the bolt by 1/8 turn", but to a newbie this doesn't mean a lot. I'm not sure what I'm trying to feel, the wings do go all the way down???

Any advice much appreciated
