Status: offline 		Basically want to know who all is using a transmitter other than the stock one. I want to convert my AXE CP to use my 9C. For one thing I think the Expo will really help me tame the bird down some. I need to know if I can just replace the receiver or if the 3-1 has to go too. Or maybe I can just change the channel in the stock reciver? (Except I think its a high band and I need low) If the 3-1 has to go, I just need another ESC correct? If so what size? If I have to get a new ESC I might as well go brushless too correct? So what size motor do I need. Lots of questions I know, but I am bound and determined to get this thing flying with my 9C since it has so many other useful options.

I'm not sure that you have to, but I did the ESC for the main, ESC for the tial, and added the gyro, then I mated it up to my 6EXH and started using it this way. I am using the stock Axe reciver, I bought a futaba crystal to match the frequency of my xmitter, swapped them out and I'm good..

you are right, the Expo will help the handling of the heli, makes it much more forgiving.

what channel are you on? I think the problem is that the stock receiver is a high band, channel 40 in my AXE and I need to be on channel 22 (low band) so I dont think I can just swap the cyrstals like you were able to do. Matter of fact I just went and bought an extra Rec Crystal and tried it... nothing.... but is the cyrstal in the AXE single or Dual conversion?
I dont have a gyro yet, but I plan on ordering on in the very near future. So I guess I will need to order Gyro, 2 ESCs, and a new Receiver. What size do the ESCs need to be. Ie 25Amp? Which ones did you use?

Status: offline 		when I bought my futaba radio, I picked channel 56, my cp was already on it, then I just programmed the radio and was off and going.

I think the axe crystal is probably single conversion.

I'm using an electrifly C-12 for the tail and whatever helimax recommends with the gyro conversion (mine has a heat sink on it so I can't see the model) hit the helimax site and you can find out what one there.

I'd go with the GY240 gyro dude, it's great for the axe and then you can move it over if you get into something else.

Status: offline 		So do I!!! I swaped the control to my Futaba 7CAP guess what for... save a lot on alcalines batteries for the Tx.
I ordered the AXE on channel 53 because my Tx already was it and everything was fine.
Kenny once you get your Tx command your heli there are a lot ahead to deal with, but don´t worry, it was my first heli and I could do it!!!!
In this moment I`m stuk in the Throttle and Pitch Normal Curves, I got a ball park setting but I´m not confortable with it. i.e. the blades wisper or buzz in the first quarter of the throttle but stop sound it in the middle. Other one is the stability at hovering I think is not the better. Just want the normal fly setting with the wood standard blades.
Could any of you list your best TH-CV and PI-CV setting?

Status: offline 		JoeVen, are you still using the stock 3-1 with the or did you have to change to a seperate ESC?
Everyone else thanks for the info. I plan to buy a hitec RX since they seem to be one of the cheapest. I was reading the manual for my 9CAP about setting up a heli and I am confused as to if I need a 5 ch or 6 ch RX. I know the AXE has 5 stock, but in the manual for the 9CAP it was talking about the different swash plates and needing to use channel 6 in the mixing. While I am on that subject which mix did you guys use SW1? From what I can tell that seems to be the correct one.

I do believe you will need the 6 channel..

Yes I left the stock 3in1 mixer and as Matheny said both heli and Tx on high band channel 53. I could fix my 7CAP setting type of shawplate, sub-trims, some channels were reversed and on. Once I get home I`ll post my Tx programing.
For what reasons are you planning improve the Rx gear? Is not enough the stock 3in1 mixer for beginners training?

You cannot swap between high and low band on the receiver.

Sorry ....wrong.
High band low band only applies to Futaba brand recievers, and then, only those labeled that way. All you need to do is get a reciever crystal for the helimax reciever on the channel you need. Whether or not it uses a negative shift reciever or not, which is what you need to be compatible with your Futaba transmitter I dont know but I think it is.

Wrong again. For the reasons I stated above. Also you can swap the channel on module based transmitters by changing the entire RF module, NOT by swapping crystals such as the 7c or the crystal inside the rf module.

Well, I'll have to just believe you on the first statement - on the second, he mentioned a 7CH, which DOESN'T have modules, and you can't AMA LEGALLY swap xtals on it, but you're correct if it uses modules you can put any channel in it you can afford (the modules are quite a bit more expensive than a xtal!!)

I have read several times that the RX is based on a Futaba design. (not directly from HeliMax though!)
