Hmm lets see, same shotty servos that will need to be changed.
Cheaper construction, i.e. uni-frame plastic; but that might be more resilient in moderate crashes, just more of a pain in bad ones.
Looks like the same type of skids on the 450D01 just no metal pipes this time, warning: they break easily.
I don't know how i feel about all plastic blade grips.
And fair warning if it's the same ESC that was on the 450D01 don't trust if for too long.
Although if it has the same main shaft dimentions as the D01 you can do the Align DFC mod to it.
Just my 2c

Fixed ID cancellation problem on Rx2703H-D

I just bought a crashed V450D03 to use as a second bird. I am having problems cancelling the Fixed ID on this receiver.
Normally to perform the Fixed ID cancellation on a Walkera receiver one should insert the Bind Plug in the battery channel and then connect the power in order to get a slowly flashing light that signals the cancellation.
The problem is that the Rx2703H-D does NOT have a battery channel. The manual states that the bind plug should be inserted into the ELEVATOR channel. I have tried it several times, but I cannot get the receiver to flash slowly.
I have read on several posts and in Youtube that some people have had the same problem.
Does anybody know how to cancel the Fixed ID???
Any help will be appreciated,

UPDATE 31.07.13
I updated the Receiver and Transmitter firmware using the UP03 cable and adapter and it solved the problem. I want to thank Jacky from helipal.com for answering all my emails and guiding me through the whole process.
My V450D03 is flying smoothly now.
