Hey guys, first and foremost - MERRY CHRISTMAS!!!
Do you guys mind to do a quick instructions on how to setup the rx2702v? I ordered one for my Trex250 from Helipal, and I doubt they'd include any instructions to set that beast up.
Thanks

NVM: Found the V450D01 manual @ walkera's site...

Had a tail servo failure first. Replaced it with Futuba digitial then I tried a Ino-lab digitial and didn't work nearly as well as the walkera then I lost a cyclic servo and replaced all with align digitial servo's and finally got them to work but it didn't feel as soilid and after a few flights trying to get it dialed in after lifting off it went fulll foward cyclic and the demise of my V450D01. I'm waiting to see if they got the bugs out before making a decision on repairing mine.

What Futaba and Ino-Lags servos did you try for the tail?

Did the Align servos you used need to be reversed? I know the ones I have are reversed relative to the Walkera ones I have had. If you had to reverse the direction, the Gyro would need to be reversed too. There are switches on the 2702V to do this. When you tilt the heli, the gyro should tilt the swash in the opposite direction. If the Gyro needs reversing it will tilt the swash in the same direction as the heli is leaning which obviously will cause big problems.

I used Align DS410M's on cyclic and for the tail I used a Futuba 9650 and Ino-lab HGD-201HB. Yes I reversed the align servo's on the cyclic and rudder and did the receiver setup and had the heli flying but the tail had excessive wander even after trying both servo's and repositioning the ball on servo arm. After completing one flight and when starting the next it might require preforming receiver setup again. Rick@Clubheli talked to Walkera and they said it might be a receiver issue and or possibly servo incompatibly. I was on the 4th or 5th flight after replacing the cyclic servo's spooling up when it happened. I had 5 or 6 flights originally before the rudder servo failed and the heli flew great with good tail authority. I replaced the tail servo and got 4 or 5 more flights out of it before losing the elevator servo and replacing them all. After talking to Rick again it appears the first production run ( which I had ) wasn't being released till all issue's were fixed.

So did you reverse the Gyro?

Yes sir.... I stated the tail wandered and didn't have the authority as before but was flyable. The gyro and tail direction was correct.

OK just wanted to make sure since reversing servos will require you to reverse the Gyro too. I wasn't sure if my post was clear enough. Aileron, Elevator, and Rudder have separate Gyro reverses. You probably know that but just in case....

I sure like to hear from the customers who have just received the few V450D01 from us. For those who have preordered on a later date, the ship date is estimated to be 1/5/2011, it is still on schedule according to our shipping manifest that the container will be delivered to our warehouse on 1/4. We might be able to ship some out on 1/4/2011. I am just hoping US Customs won't delay this load.

For guys who are setting up the RX2702V on the Trex, you may have to reverse the gyro sw on the receiver depending on what part of the heli you installed it on.

As far as the 3 page manual goes. 2 of the 3 pages are from Walkera V450D01manual, except there are quite a few mistakes in the original manual which took us some time to figure out and correct. Guys who have setup an Align 3G should probably get pass these mistakes and figure it out without much problem. After we have edited and corrected the Walkera manual, we made it into step by step and added the critical WK2801 setup which is needed before setting up the gyro.

This is correct. The receiver firmware was updated and Walkera engineers did an excellent job on this with the help of the DKfuji report. The tail servo has some over heat problem but now it runs like a champ at .08 speed. The hardware failure report was generated by a Taiwanese Pro who has also greatly contributed.

Sorry for my bad English.
This is the difference between this receiver and the RX2610S/V. The receiver must be setup specifically for the WK2801pro you are going to be using. The same settings are no good when exported to another radio. The set button is used to identify the mode under which it's been set and to memorize the end points of the sticks. The flashing sequence is confusing because some of the mistakes in the original manual.

Hi Jonathan,
I really appreciate your contribution ! I also need some help on setting the RX-2702V on my Trex 450 with the WK-2801pro. Your step by step guide would really help me out. Could I purchase it separately from you please please.
