was your wheel on tight enough. it may have moved up causing the chain to loosen.

1) get chain tensioners? - don't be a cheapo, get chain tensioners for both sides.
2) slam your back wheel?
3) find ball bearings and stuff them into the empty space in front of the axles when it's in the dropouts?
edit: #3, ball bearings in dropouts = not my idea, read/saw another global-flat rider recommand it, can't remember who though...but it must be a snug fit between dropout space and axle, if not bearing won't stay put.

yes it was on pretty tight

when you crank down hard six things can cause your chain getting loose again:
1. shackles of your chain wear out when old, or "set in" when new.
2.backwheel moves.
3.you dig your chain into the aluminium of your sprocket (alu is pretty soft)
4.there's some play between axle and sprocket
5.bearings wear out and the material that cradles the bearings gives in (alu is pretty soft)(there are bearings in the bottom bracket and two undersized bearings rolling on top of each other in your freecoaster so that's a lot variables to take into account)
6.due to a worn out chain, improper alignment of bottombracket or backwheel, worn out or bent sprocket there can be a loose spot in your drive train. You could have tightened your wheel on the spot where it's the tightest.

tensioners tensioners tensioners
they aren't necessary but they make my life a whole lot easier.
the last thing i want to do is fight the back wheel into alignment
AND keep the chain tight as i like it.

hmmmm... i never actually thought of that

so tensinors will solve the problem ?

tensioners make life easier
if you can't use tensioners, like if the slot is too short to even use one (many frames now have this issue). you gotta go with bearings or the simple wheel slammers.
if you're using a nankai or taska find better outer lock nuts for the hub that have knurling to grip the dropout. titanium hardware, and axles dont help.

I read an interview with Dane Beardsley and he said he used some spokes for chain tensioners. Anyone know how you do that?

he cuts a small portion of spoke then bends it with tiny tools and puts it betweenst his axle and dropout.
