Hi,
i am just about finished building the stevens aero Dystraction, nice looking plane and i have installed all my servos where they are needed i have installed a 10a brushless speed controller with a tornado out runner mini bell i think?
once i have bound the transmitter to the 6100e all surfaces move as they should
i am getting glitching and when i make agressive stick control with the ailerons 
i loose signal after a period 3-5 seconds it recovers
can any one help me ?
thanks

Too much load on the BEC perhaps?  How many servos?  You might need a separate rx battery or a uBEC

The BEC in a speed controller can only supply a limited current - especially if you use more than a 3 cell LiPo.  Yours is a fairly small speed controller.
 
If the BEC is unable to supply sufficient current you may get a drop in voltage causing the receiver to brown out - Timbo would know more about Spektrum receivers than me and will probably confirm or deny this?
 
A uBEC is an additional voltage regulator that works without trying to dump excess voltage as heat. They aren't expensive - try a Google search or pop into your local model shop.

Are you getting these problems when ground / bench testing? if so, you could be swamping the system by holding the Tx too close to the model.
The 6100E Rx are only classed as park range incidentally, and many were released without the latest quick connect firmware. It does sound as though you are suffering a brown out and your Rx is not QC enabled.The fact that it happens after twiddling the ailerons suggests that the extra load of two servos is pulling the supply voltage of the BEC down below minmum levels.
Martin is correct, you should use a UBEC or separate battery for radio power if you are suffering brown outs - the BEC in many ESCs is simply not up to the job.
