    I just got one of the mX 400 today and had a himax 2015-4100 and was wondering if that would work in this heli or if it would be to much.

    Thanks
    John

    Status: offline     		I recently got a MX400 and it needs electronics. I was interested in the Align 35a speed control w/governor and the Align 420 motor. Does the speed control perform work well or is low quality? Also, I can't swing the outrunner motor right now and saw that the Align 420 motor runs great for the price. I am also interested in getting a good receiver. How does the Align 6ch receiver work?? Any help and other ideas for electronics are welcomed.

    Status: offline     		I am ordering the MX400 but I am in the dark as far as brushless motors go. I have been flying RC nitro aircraft since the 60's. My first foray into electric was a Blade CP which I have been flying for 4 months now. What would be a good brushless motor for the MX400 and also a good ESP. I just bought a Hobbico Elite three cell charger for the 1350 MHA Lipo's for my Blade so I am limited to three cells. Don't know if this is a problem or not. Anyone have any idea how long the MX400 would fly in 1350 Lipo's? Any help would be appreciated. I would like to order the motor this week. Not looking for a killer speed or anything but something that would be reliable but allow me to explore some of the capabilities of the MX400.

    Thanks for any help

    Status: offline     		jaless,

    I can't answer for the best brushless motor but if your lipo's have a good c rating (10 being the lowest and higher is better) then you should be able to get some good power but for less time than the higher mah rated batteries. one of the good things about the lower mah batteries is that they weigh less and make the model much more nimble. I just charged one of my 1650mah 3cell batteries that was used in a 10 minute flight with my #35. I was practicing loops so I had it in idle up mode for at least 7 minutes and it took 1100mah to top it off again. since you will want some safety factor, i am guessing flights of 5 to 7 minutes of hard flying and more if your just putting around.

    Status: offline     		Guys,

    Well I went ahead and ordered the Ultrafly C/13/33kv and and Electrifly Silver Series 35A ECS for my MX400. The Ultrafly sounded like a good idea because it contains an internal cooling fan. As for the ECS, do I want set it up for the internal brake or not? What are the pluses and minuses to doing this?

    Status: offline     		I have that esc on my MX400 with the Mega motor. I do not set up with the brake as it can be harder on the gears. It slows down pretty quick anyway without the brake. I like the lipo cutoff feature also. It does not cut the motor dead, but rather pulses to a stop leaving just enough power to land.

    Thanks for the help. Are you flying the MX400 yet? What batteries are you using? I plan to start out with Lipo 3C TP1320's that I had for my Blade. I am still training on the Blade. That was my first heli. I plan to continue training on the Blade befoe I move up to the MX400. Don't want to crash that on right off the bat.

    Status: offline     		I have flown the Blade and I think the MX400 is MUCH easier to fly. With the mega 3 turn motor I am using the Kokam 3 cell 2000 pack. The packs that I use with my Blade and Esky CP2 were the 3 cell 1500's and they will not put out the power for the Mega. I only get about 7 minutes with the 2000's but maybe I would be better off with TP 2100's. I use the Kokams in my planes so I just tried them in the MX400 and they work ok, but not great. I think the Kokams are a little weak anyway.
    As for flying, it is so nice and stable. I had it outside in the wind and had no problems. I don't have any negative pitch setup yet, but so far so good. If you can fly the Blade with any control at all, you can fly this bird. I fly it in my basement as well as outside so don't be afraid. I also like not burning out tail motors every other flight. I bought a direct drive setup for the cp2 but havent tried it yet. Have fun

    Status: offline     		Scott,

    Good stuff, thanks for all your help. Looking forward to setting the MX400 up. I like to tinker and have been building RC planes for over 30 years. Never thought much about getting into heli's until I saw the Blade. Guess I got hooked. Still working on right side and nose in hovering but I can hover the Blade tail in nice and left side steady for the whole pack, about 20 minutes. I will use the 1320 lipo's to test it out but will upgrade to a higher rated pack once I get started. Thanks again for all your help.

    Joe

    Status: offline     		Can anyone give info on where they placed their electrictronics.
    I have the Helimax set up from Tower 2540 6 pole motor and 25A esc.
    I put the ESC underneath and the rx under and behind the main gear.
    I am getting a glitch. It seems to fly good until the motor warms up. Then it seems I can feel a slight wobble and it will glitch...
    I am not sure what type of cutoff the ESC has, but it does this after about 30 sec of hover.

    Any help would be great....

    Thanks

    Status: offline     		Guys, sorry for the long response time.

    Ive been hiking on the Appalachian Trail. No computers up there.
    I just got back.

    I have decided on a motor. One of my friends has a Align 420 with the ESC that he's gonna sell me cheap. Im gonna put that in the heli. He had this set-up on a Trex, and it worked great, so it should work fine with the MX400. Ill let you know how it works out.

    If anyone is interested, Ill be posting pictures of the AT trip up on the web soon. Ill post the web addy once I get them up. Im still on brain overload coming back to civilization.

    Status: offline     		Being new to electrics you never know what to ask until you get to next step. I figured that I would just get the Futaba GY401 right off the bat but now I find that I will have 5 servo connections due to the sensitifity connection on the gyro. The Silver Series 35A ESC has BEC but mentioned that it was good for up to 4 servos. Does the sensativity connector count as 1. Will I be able to use the GY401?
