just got an ARK400 from the some times dubious rc expert, kit is great and built nicely. Only thing is the ESC supplied is an RCExpert 40A and so so instructions, I have searched the forums for a while now and have not seen this ESC refered to. I am sure it is a fairly new addition to the RCExpert combo kit line and more than likely a clone of some kind. I just dont know what it is a clone of. I have been in electric plans for a while but I am just passing the novice part of Helos. I fly the real thing for a living and am totaly addicted to RC's, the most fun I have had in years.
I am new to this forum stuff, so if I make a feux pas, please let me know.

Will post pics if it helps

I have the same one...

I just got my Ark together and spooled the motor up the for the first time last night. I agree the instructions are not the easiest to follow, but if you follow what you have it should get you going. I got lucky the first time I hooked up the motor that it was turning the correct direction. I still have a lot to do before she is air worthy.

I might be able to scan my instructions and you can tell if they are the same or help you any?

I've got one of those rc expert 40A escs in my X400, and works pretty well. Low voltage cut off works in pretty fast, so watch your run time, or you'll be practicing autos. I think the motor is the weak part- not efficient. I went to an Astroflight 020, significantly increased run time, but no real change in performance. I have a JGF 450TH yet to be installed (lighter than the Astroflight, probably more powerful too- how could I lose?)

I am almost at the power on stage myself, should be fun. Thanks for the input, I thought it looked like a fairly well made componant so I was interested to see if there was more info on it, I will definatly use it though. I will try the instructions and post again if all is not well, but if you say it works out, then I will give it a go.
I agree with the motor, I don't always judge a book by the cover, but having had some experience with electric RC it does look suspect that it will hold the 3200kv (advertised) when needed. How does it do on climb outs and peek requirements? I think it should work for my back yard hops just fine, and I will upgrade as my skill set demands. I will be sure to start the timer on my radio, having done auto's in the real thing, I don't think I or my wallet are ready for that yet! just moving up from a Hummingbird, need something stronger for light winds.

How much time?

So how much time should we allow for the 1200 or 1700 3 cell. on the motor from rcExpert?

Hmmm, 1200mAh may give you very short flights indeed. I have used a 1700mAh (the one that came with the package, and so far it's actually pretty good), and get about 7 minutes. Likely you'll want to add some 2100's or so to your stable. I have had good success with batteries from commonsenserc.com. Go for at least 15C packs.
