Foir a while I kept up with all the trex500 problems with the spectrum radio, but now I've lost track of whats happening.
So maybe someone can help me understand.
The reason for the lockouts on the DX7 (AR7000, AR6200) on the trex500 seem to come from several things one is static spikes radiating in the carbon frame, and EMF from the motor in the carbon frame. Another is the BEC overloading and dropping below the spectrum rx reset voltage.
Its hard to see just how common the problems are and how many folks have been flying without incident. Several very active fliers have had lots of problems and this masks how many don't have problems.
It could be that the problems are rare on the G10 frame version.
Why the 500 is so bad is not fully understood. How come the spectrum seems so reliable on the trex450? (which is mechanically and electrically very similar) - and also reliable on the trex600e which also very similar.
Problems with the spectrum system on nitro helis seem to be very rare indeed.
Only problem with spectrum at out field (so far) was in a large plank with an underated regulator. Voltage dip and reset could be reproduced by loading the servos.
My spectrum has not missed a beat. It never missed a beat running of a 4.8v nicad.
I am now running a 2 cell lipo system.
I am running the servos on 6v from a 2in1 with step down for the tail servo. The rx runs direct from the 7.4 volt lipo bypassing the regulator.
I've done the same thing on my new 600npro as I did on my raptor. 600n will fly this weekend hopefully.
On spectrum my 450 has never missed a beat. It runs on 3 cells using the quark 33a BEC. The frame is a helidirect G10 superframe (not a standard trex450 frame).
Apart from a few switch assigment issues and the balance of the neck strap (which needs a bodge mod) I cannot criticise the DX7 at all.
