Using a 3 or 4 blade tail rotor might help if this problem occurs.
I did try it, using a standard (variable pitch) 450 tail and F45 Rx: it did work, but (I agree) not very well. Perhaps for the reasons you've given
As above, still working on a better BL conversion first: though my present system is pretty good, have to admit it's still not quite as good as the brushed tail.
However, mine worked a lot better with belt tail using my 6ch Tx/Rx/gyro. Perhaps Rexless' idea using 5deg? funcopter blades will also necessitate him getting the headspeed up as you advise. Certainly got to be interesting seeing how his FBL conversion goes.
