don't see any reason it wouldn't work...You can plug in the dongle and do phazing if needed, just don't try to upgrade. Check with the website and see if that is avilable yet. They were supposed to have that feature available by now...

I have been using a Spektrum AR7200BX in my Century AS350 with a three blade head without any problems. I used mechanical phasing with the Century Diamond head. There is plenty of room for the links so there is no problem getting the phasing correct without any of the links binding on anything.

I have also set up a MD500 using the AR7200BX with a five blade head, also mechanically phased, using the Trex 600 ESP mechanics. No problems there as well.

You shouldn't have any problems with that setup.

Hi:

If I could make a helpful suggestion about links and balls for the 3 blade head. I have just finished the main mechanical build for a Century AS350 600 size with the Diamond head and Align 600E Pro mechanics. I found that the balls from the 700 Nitro worked great on the grips and on the swash for the pitch control links. I used Linkage ball B(M3x4)(Ö5x12mm) on the blade grips and Linkage ball C(M3x3.5)(Ö5x8.5mm) on the swashplate. The rods were two sets of their H70066 rods and links to give me a very strong linkage system from the swash to the grips. I found that short balls on the grips would let the links get a bit too close to the arms for my liking, hence the slightly longer balls. I only needed to do a mechanical phasing of the blades as the helicopter has no tendency to drift left or right when input is given. Hope this helps.

You can't do electronic phasing with the AR7200BX, this unit is not compatible with the BeastX software. Phasing will need to be done mechanically. Spektrum has not come up with an interface for it yet that I know of...

However, if it can be mechanically phase the AR7200BX will take care of the rest..

My three blade Diamond head came with the longer balls, the five blade head came with the short ones. The longer ones definetly work better with mechanical phasing.

I did a mechanical phase by putting the blade I was working on over the boom and setting the ball on the swashplate at 90 degrees to that. I have done it a number of times on various heads and find that it is rather simple to set it up then use a digital gauge (like the one from RC Logger) to verify that the blade remains neutral during elevator input. Worked like a charm. Take care.
