Thanks! I got the wire and my connectors from RCDude today and 14 AWG is the perfect size for soldering HXT and XT60 connectors.

Any smaller and there would be a small O.D. void requiring a little more solder to boil before inserting the tinned wire. If you put too much in the HXT it may over fill into the little hole and get into the locking groove for the insulator.

The wire is very nice. Very flexible and super high strand count. I like this Dude.

Since most after market batteries come with XT60 connectors I made an adapter so I can go to and fro the OE and aftermarkets.

I did know walkera had made some changes in the production of some parts, but like i said before, i've never had to change a feathering shaft or blade grip on my v400's. I guess i'm lucky. I have 3 complete spare heads sitting in my parts box. I wanna try one on a 450pro cause i've been through many heads on that heli. It now has a dfc head but who knows how long that will last.

Just saw Daver Herbert's video. Wow, nice for beginners. It really flies nice. I'm sure if I got one it would not fly like that, I have the worst luck with Helis. My last Walkera was a POS and the 3 axis gyro does not work correctly (V370D01). On Dave's video, he says it came with the DEVO 7 for $159. But I just see the dated WK series one for $159. What gives?

I just looked at it too. When he does loops I don't see much if any stick movement on the right side. It doesn't click for me, get it.

Oh, which video you talkin about?

This one.

FLYBARLESS Walkera V400 3D TRAINER Heli has an e.T.R.M. A review by NightFlyyer. (11 min 57 sec)


It says $159. Now they only have the Exceed version for $205. No thanks. Don't know why I am even looking. I have already given up on an Esky CPX, have a clone that I can't get the tail to work, and now having tail issues with a Hausler that I got because it was reported to fly well out of the box. I like the micros, they fly so nice, like the Nano and even my Solo Pro 100. I just want a collective pitch heli, but $200 is too much to risk, as most never fly with me. Plus I don't want to pay extra for Walkera's radio that they re just going to dump like they did the WK series.

I have brushed to brushless converter, and I've been flying with my v400 but I crashed it down and all stock servos was destroyed. So I will make some small upgrades on my babe and also I'll need soft-starting ESC.

Now Im just thinking about upgrade of tx+rx, cause setting of wk2603 is little bit heavier for me (everytime when going to setting is everything deleted) and also Im not sure about gyro in rx2614v cause last time when I've been hovering my heli suddenly flied weird and uncontrollably and crashed down. It was quite unstable.

So I just wanna to know if anybody from you tested devo7 or devo8s with compatible rx (RX802). And which gyro should i use.
Thanx.

To expand on kdeans response above the you need to go with the 2614 receiver / tail and cyclic gyro. The 802 doesn't have any gyros but is a reveiver only with it's unintended use in a 450 on up using BeastX, GX, Vbar etc gyros. Way overkill for the 400.

You mention that you are loosing changes made to your 2603. You need to follow the instructions verbatim when using the enter key. If not you will loose the changed setting. This link may help:
walkera 2603 setup with v400d02.MOV (18 min 54 sec)


I would disconnect the main if you have your new ESC, or power the 2614 from the stock one, like I mentioned on the last page, and test the tail by hand. Let the gyro lock, change rudder position, move the heli and let it lock, etc. Disconnect the battery, rebind and repeat several times and see if you can get the gyro not to lock. If it doesn't lock get another 2614. It's you choice if you want to get another RX2614V to use with your 2603 or get the RX2614V-D and Devo Tx. Let us know how you make out. Many of us are using the 2614 w/o any problems.

So if one needed that part how would he know which to order? Thanks.

Other than getting the entire head for $40 - $45 the only other part you can get is the feathering shaft. I have 3 on order and the photo looks like the bottom one w/o the tapered ends. Thanks Walkera!

I ordered a heatsink and got two. I installed them today cutting one down to fit.

I had to shape them because after snapping them on I could see they were only touching the motor body at the tips of the ends and just barley at the center. Not a very good way to sink.

Anyway. That's that.

Those Esky heat sinks were made to fit a motor like the one in my CB180D at 24mm not the V400 at 27.5mm. Need to get some better double sided tape for that receiver.

Thanks,

If your saying better tape because of the rubber bands in the pic, those were just to hold the battery down while I tested and checked her balance and such. But if you are saying its a known issue please clarify?

Those are the heat sinks are what I have seen suggested for the V400. If you have better please toss it at me.

Thanks again

Ok. Thank you very much for info. I'll test it and I'll let you know.
And about tx 2603 I thought that i loss settings when i re-enter setup. I think know how to save and go thru it but it's a pity if i wanna to make small change (for example gyro sens from 80 to 90%) I'll have to go thru many settings with knobs v1 and v2.
Will see if I'll stay with wk2603. I hope so.

Just bustin' Looks like they are holding down the receiver.

Actually Esky does make a HS for a 370 / 380 motor. Wonder why the center isn't in contact? I apply a thin coat of thermal grease on 180 but that only works if it correctly fits. Try bending it better to the contour of the case then slide it on the end instead of snapping it on the side. That causes it to get deformed. You will probably need to remove the motor because of the PCB on the top.

The 2603 is known to be very un-user freindly. I've just shelved mine 2 days ago after getting my Devo 10.
