I'm trying to set up my CCPM. I'm building my 1st T-Rex 600N. I have installed 3 DS 610 cyclic servos and I have a Futaba 7C 2.4ghz TX. I went to futaba website FAQ, but I'm not exactly sure which CCPM I needed to input in my TX programming so I can adjust my servos properly.

There's a couple of suggestions so I input the HE3 firstHE3 Type: Pushrods positioned as shown. With Aileron input, the aileron and pitch servos tilt the swashplate left and right; with Elevator input, the servos tilt the swashplate fore and aft; with Pitch input, all three servos raise the swashplate up and down. Most commonly used for Electronic Helis) but, it's also suggesting that

H-3 Type: 140 degree CCPM. Pushrods positioned as shown. Fundamentally, the servo operations of H-3 type are almost that same as HR3 type. However, the servo arrangement for elevator operation differs. 140 degree CCPM offers smoother operation of the combined servos and an equal cyclic rate all around. On a 120 degree setup, the left/right cyclic is slightly faster than the fore/aft cyclic.

This is the Futaba site: http://www.futaba-rc.com/faq/faq-q1056.html
Anyone like minded using this setup. Can you please reply. Thanks in advance.

I think I got it.

Well, I think I got the set up because the swash plate is working the way it's suppose to be. I had a friend help me and I got it so far, Now I need to adjust the servos so that when I get this Heli to have a test lift off everything should be fine.

I maybe wrong, but the Trex600N isn't designed for CCPM 140 without modification, is it?

Hello guys thanks

Thank you for all of your help. I found out that I need to set my Futaba Tx to 120 CCPM which is HR3 on my TX Futaba 7C 2.4GHz. I had to play with it and had a friend in HobbytownUSA to look at it and told me that's it. Also, I had some help with the Futaba tech dude before and I wrote down some of the important things like the Swash adjustment to 85%+ for Aileron, 85%- for Elevator, and $45%+ for Pitch. It seems to work normally and my next adjustment is the DS 620 servo by Align that is hook up to the carburettor. I need to get someone more experience than me in the field this coming weekend. We fly here in Date St. Temecula. I hope some of the guys there can help me set up the mixture and adjustment. Thanks for the info. Thumpernator, that guy that gave the info in the RR forum should be paid for writing a book. Wow nice writing.

That's what I thought, though CCPM 140 would be nice.

those swash adjustments are jacked and all 3 shoule be even.

45 -50 is a safer bet

go watch finless vids at heli freak on ccpm set up on the 450 in the tech section and you will learn tricks I still use today

Forgive me but I don't understand 45-50. I will watch the video you recommended and I will experiment on this set up. Thanks for all the reply.

I think he means swash mix percentage.

ccpm 140 you might bind unless you updated your swash

Watched Finless Video

What a cool video gig Mr Finless has. The only thing is, I think he forgot to make a video on how to balance the fly bars before installing them in the Heli and input all of the mechanical configurations on the 450 Heli. I have a 450 AXE and I set it up the way Mr Finless has shown in the video and I can see the big difference in the settings. Only one thing. I almost screwed up when I put everything back in the reversing mode to normal and my 450 Heli wont work for the mean time but, then luckily I always take out the blades when I test it on the dry run and whammo!! the Heli turned on and wanted to take off but no blades. Almost panicked but I controlled the heli. I just needed to remember that the Throttle stick can be shut off in the reverse as well. I got that fixed That was close. Lessoned learned like I always do is that when you're not sure, you always start with the basic and my basic was to remove the blade always when doing a dry run. I always remove the ESC power source from the to the motor too when I'm straighten out or adjusting the linkages in the head to make sure that they're always balance. Thank God for the corrected mistake. Also thanks to all of you here. One more thing do we have a video on how to correctly adjust the servo and the nitro on the OS 50 Engines?

i think at this point you probably want to get some experienced hands on help. even a well made video can't capture the variables involved in ensuring a properly set up throttle and engine break in...not to mention having a second set of eyes to look over the heli before that first flight. plenty of help around both in temecula and a little further north.

Hello Koppter

Hello there. I know what you mean. Tomorrow I will be at the Date St to let the other guys know what I did. I finally learned something that it's very very important. Even though Thumpernator suggested that I should read the posting here and outhouse said to watch the finless Video. As a matter of fact I downloaded the book then I followed it just like the numbers would say and it works. I learned from other people's experience. Because when everyone else is in the field, I noticed that they want to fly their heli's and would not have time to explain other things that are very important to other's.

I think this is a great place to learn if you're willing to follow the rules. I read and read and watch the video's and now, I can say that I'm experiencing a tremendous amount of excitement because the answers are just here. Of course without the internet, RR, Helifreak, and google we can still call one another which is really an obsolete communication trademark. Getting the info I needed is just as easy as going to 7-Eleven and getting a quick snacks. Only here you have to read to feed the unknowable brain to make it knowledgeable. Thanks for the advice koppter I hope to meet with you someday. I belong to Palomar RC in 76 south of I 15.

I think most people are willing to help others at the field, but it depends on what it is. For instance, we've had guys show up with a heli that needed all the linkages redone and then a complete setup with the radio settings. To me, this is something better off doing at the house and not at the field.

A lot of us have limited time to spend at the field (I know I do) and yes, we do want to fly our helis. For someone needing that much help, I'm more than willing (and I'm sure others are too) to have them come to my house, or me to theirs, some evening to help them out. Also, I think there are too many distractions at the field to do a complete setup from the servos to the blades.

That's is well said Thumpernator

Well said, I love to help out also but my heli knowledge is not there yet. I know from experience that what I do is just for fun and I'm having fun working on the Heli especially when it needs to be clean.
