As the thread topic says, what are the key differences between the W323A and the W323B?  I know they both have the new, updated motors, but is there any differences in the shell, or any other parts for that matter?  I had a W323B but ended up losing it due to a defect in the RTH function, and got a W323A in replacement.   Any feedback would be appreciated.  Thanks!

Anyone know by any chance?

Have a look here... Third post down.

Thanks Tintin but those don't describe differences between the W323A and W323B...only the W323 and the W323A..

The A is the original P3P and the B is the upgraded.  B has new shell - no cracks, upgraded motors, some of the electronics were incorporated to one board.
