i fly Nitro heli and want to get into the micro electric. i have a blade cp and i can hover this thing inside but want to build a trex ccpm and have it more stable, be able to do 3D, so my question is i know i will need a micro futaba RX since i will be flying with my 9chp, micro servos, i will use the gy 401 gyro, some kind of brushless motor maybe alighn motor. what else is there could someone please explain. and maybe what type you like. i want this to be a real good heli with top quality parts.

i am now using my 9chp with the standard rx that came with it. the 149dp. its pcm and it fits in the back of the main frame. its a little big but it does fit and i never have to worry about glitching or and interferance! i just bought the futaba r146ip. its a small pcm rx. i havent ried it out because i really have no problems with the bigger 149dp.

One major thing you will also need is an ESC (electronic speed controller) This is what drives the motor, like the servo to a gas machine... A lot of people use the Castle Creations 35amp ESC, or the Align 35amp speed controller. I personsally use the align with the align 3200Kv motor... A lot of people are using mega or NEU motors as well for good 3d flying.... the align 3200kv motor lacks a little punch needed. Some people are also using digital servos for their tails, as analog servos don't hold the tail as well as they should....

But Honey, I can't live with just stock.....

I'm also using the Align 35A and Align 3200kv (420LF) motor with 13T. Unfortunatelly in governor mode this setup does not work well: head speed starts changing all the time which causes tail wagg...
Does not have this problem by using non gov mode and classic throttle/pitch curve.

Any suggestions to resolve this?

this info helps alot i have seen other post on governer problems, is the governer something built into every speed controller? and how many different and good quality speed controllers are there. i know that a governer is an option that you install onto a nitro heli and makes 3d a lot easier.

Swattley,

Yes, Governor mode is built into the esc. Some ESCs has it, some don't.. To save you all the wiring hassle of a piggyback BEC system, get a Kontronix Jazz if you plan running 4S or more.. For learning pilots like me who do some pretty basic moves I'd stick with the CC35, it's cost effective.

Gov mode on some ESCs work well, or maybe it's more of a setup issue of it not working well.. or pilot laziness to figure it out.. hehehee..

Don't get an Align motor, I have a 420LF, heats up on 13T with proper mesh.. 400SF works well with reasonable heat, but this motor is just for beginners. 420LF has not much punch. Get a 450TH which they say runs cool and has the punch.. Can't wait for it to arrive.. Hehhehee..

I agree, my 420LF doesn't have the punch... I have heard good things about the 450TH as well... Does align make the 450TH??

But Honey, I can't live with just stock.....

swattley,

I also use a full sized Futaba PCM RX (R149CP) for my TREX 450XL with no problems at all. Just as ECOHELI said, it fits perfectly inside the main frame.


good luck

when i set this heli up i want to build it to have some real balls and do the 3d that i know it can. so what ever motor is best i want to go with it. i am not able to do 3d yet but i wnat to build it right the first time. what do you think about the alighn speed controller? it seems to have some nice options.and what about 35A or 25A speed controllers is the 35 better for pushing this heli

You should definitely go for the 35A ESC even with governor. I've had some issues with the 25A especially with thermal shutoff. The problem would probably be less residual if you use the 35A.

Or you can get yourself a Kontronix Jazz speed controller if you plan on going high voltage, with a corresponding motor you'll have enough punch for sure.

The speed controller will need to be able to handle the better motor, so I would then go with a Jazz right off the bat.. Read some posts about going HV (high Voltage), basically 4 & 5 cell battery setups. I don't know what the best 3d motor is, but I'm sure some people will have their favorites. The other thing that comes in with using HV, is a seperate BEC (battery eliminator Circuit) to limit the voltage going to the rest of the heli, ie: the reciever and servos....

i think i am going to stay with a standered voltage. i want a good reliable motor but power full enough to do inverted flight and other 3d manuvers and still be able to stay with a normal voltage or battery pack. maybe that will come later. even if i have shorter flight times for now. my Nitro heli will still be my main bird.

any opinion on motor manufacters i see this one AON on several sites.

There is no "standard voltage". A lot of guys (including me) are running 3S. My setup is a 400DH motor, CC35 ESC and Kokam 2000mah battery. The governor on my CC works OK. The heli has more vertical performance than my Caliber 30 with a Toki 40 engine in it.

One of the issues with running 3S batteries is that for good performance you are going to draw a lot of current. Many batteries arent up to the task and will fail at high current. If you are going to run 3S make sure you get a battery capable of at least 15C.

If I were starting over I'd go 4S. I'd use the Kontronic ESC (way better quality than the CC and can handle 4S without the need for an external BEC). I'd use the Thunder Power Pro Lite batteries. And I'd go for a Medusa or Neumotor.

Everyone is going to have their own opinion, and the choices I recommended arent the cheapest way to go. But then you didnt say you wanted cheap, you wanted good.

Check out the Trex video on this site and see if this is what you have in mind:http://www.tppacks.com/products.asp?cat=15
