So this weekend I finally got a whole load of updates and modifications sorted on my X400 and I thought I'd drop by and let you all know the results.
Items fitted list:
GY401 (at last)
HDS 877 (on the tail)
HS 56 B (Aileron control)
Flightpower Exteme 20c 1800mah
First off lets cover the HS56B. I'd heard lots of good reports of this servo and as my HS55 was wigging out on the aileron control I thought I'd drop this in. What an improvement, a lot easier to fit than some forums had led me to believe and really precise and powerful. In flight not a huge differnece but it really does give me more confidence over the HS55.
Ok the big one (in my opinion) the GY401 and HDS 877. What can I say, after a lot of fidddling and a little learning (of setting up the GYRO in my tranny properly) I finally have a tail that holds properly, and what a difference. I have the Gyro set up in digital mode and the repsonse is excellent.
The AVCS mode of operation of the GY401 is a realy improvement for me over the way the Alight HH gyro works and the rate at which this thing corrects the tail is very very impressive. I relocated the reciever to the LHS of the heli and dropped the GY401 between the frames at the back where it fits very well.
I was so confident in fact that the single piro I did the other day became 4 in a row continuously, and in both directions. Small beer to many but a big deal to me - and great fun as well.
Only issue was fitting the servo, I use a TREX Boom mount and the brass inserts for the servo wouldn't work with my sorter hex screws, so I had to do a bit of bodget and scarper and make them fit - all good in the end.
As for the Flightpower lipo, in a word nice. I've been using a Kokam 2000 mah for a few months now and really rate it. The flightpower actually outlasted it by 2 minutes, which amazed me. Also lots of power on tap and it didn't get any warmer than the Kokam. The other advantage is that it fits in the frames of the X400 well.
So all in all and after a lot of tinkering - the X400 is flying like a dream, the control is now very precise and it's alowing me to fly it like I do the sim - well the basics anyway!
Next up (and I'm in no rush) is HS56s for the pitch and elevator, and also the cnc elevator parts for the heli.
Now I finally have a new lipo I will be using the EYECAM again as well, as I can now run it in the middle of a field - here we go!
