Has anyone tried the CCPM conversion from Helikraft? Wondering how it works and how you like it.
Thanks

I'd like to know as well. Kind of pricey, but it's either pay it or make it yourself I guess, haven't seen very many of these conversions for sale.

What I'd really like is one of the conversion kits shown here http://www.tppacks.com/products.asp?cat=17 but it says out of stock and I got no reply to an email asking if they plan to restock.

I did download the installation manual from Tppacks and I'm thinking about having a go at making my own copy. Not a trivial job, but I do have a small lathe and mill in the garage with enough 6061 alloy to do it.

I have always wondered why people insist on converting the Raptor to ccpm. To me, the biggest positive aspect OF the raptor is that fact that it is mech mix. ZERO interaction and easy to set up.

In my case it's because my R 50 is also wearing a Trex 600 rotor head and I can't quite get enough pitch with the mechanical setup. eCCPM will get +/- 12 degrees easily whereas the stock setup is limited to slightly less than +/- 10 degrees with the different head.

i see. I would suggest getting the washout arms for the Raptor 90, and install them on the Trex washout base. You'll get quite a bit more pitch.

Thanks for the tip! I just happen to have abox full of used but serviceable R60 and 90 parts, I'll have to give it a try

It was more of interest as I saw it on their site and wondered what ppl thought. For the flying that I do the original setup is fine. Just curious that's all.

I've also taken my dremel to the frames and opened up the slots for the collective a bit. This lets me get right near +/-12 without changing the flybar ratio.

I've heard the guys down Miami way have done the dremel to the frame and been quite successful. I understand they can compete with the T-rex 600 with that mod and some frame lightening.

This hobby is WAY too expensive!!

All of what you suggest is true but the biggest advantage of ECCMP is that the servos work in concert to move the swash. Collective is the ganging of 3 servos not one. Cyclic is the combined effort of at least 2 servos. With this ganging of servos, you could expect 3 times the torque or speed and better servo holding and centering.

True you get to add up the torque and centering abilities, but there is something to be said for a system that has zero interaction. I have flown lots of CCPM birds, and with a quality collective servo on the Raptor, the collective feels great and the cyclic is totally separate. I'm not even running the push-pull conversion on my collective (I think my bird started life as a 50 SE), and with an ACE 1015 servo there is zero slop or centering issues. One thing that bugs me about CCPM (at least 120 degree) is you always get some rising and settling of the swash when you give fast cyclic inputs. It becomes less noticeable with good setup and fast servos, but its almost impossible to completely eliminate it. 140 degree CCPM is a better option, but you need perfectly matching high end servos. Although I still like my CCPM birds, the more I fly my Raptor, the more I appreciate how clean the controls are. As I am getting used to it (this is my first mechanically mixed machine since my first Raptor 30 v1 over 5 years ago)I find complicated piro maneuvers like Piro tic-tocks come more naturally, and maneuvers like backwards rolls are crisp and stay on track with ease.

two kids? how'd that happen? time to zip'm up!!!

I'm aware of the 3 servos working together, but use a good collective servo, with 150 oz. in. or torque and the collective can be quite snappy on a raptor. 3 servos working together to move the swash up and down does not increase speed. Torque yes, but there is a point where enough torque is enough.

I have two of the TPPacks CCPM conversions. They are not selling them anymore. They were the best conversion out there as the links go directly to the swash from the servos. The reason for me using them is that I converted my Raptor to electric and I needed the room up front for my batteries. There's a picture in my gallery of how it used to look. It still looks mostly the same but I have made more improvements to it over time and should really put up some new pics.

If you skip me I can't play!

Is it just me or do these conversion kits look sorta of Centurishly designed? Reminds em of someone buying a sport bike and putting ape-hangar handle bars and saddle bags on it.

Check out the xero g conversion. I have 3 two setup and love the way it flys. But there is not much stock left. Same with the v-max conversion for the raptor 90. Flys great too.

I should have added... I have two Raptors and am not anxious to convert ether of them to CCMP. As others pointed out, the simplicity of setup and lack of interaction makes NON-ECCMP attractive.

The largest negative to the conversion noted at the beginning of this thread, at least in my mind, is that replacement parts may be more difficult to find. I have several large X-Cell .90 but really love my Raptors for their inexpensive readily available parts. My Raptors are in the lineup so they can be crashed (although I don't crash them) and this conversion doesn't fit that purpose. If I need to work on a maneuver I'm not 100% certain of the outcome, I grab the Rappy. If vertical separation goes to zero, I can sometimes fly it the same day with parts on hand. Otherwise, a phone call and 3 days latter Mr. UPS will have it flying the next weekend.

That's not entirely true. My Rappy has been tossed into the ground several times with no damage to the CCPM conversion. CCPM is simpler to assemble than the stock Rappy as there is less parts and linkage. As far as interaction the MCCPM does win with pure inputs, however a properly setup ECCPM using a swash plate leveling tool flies just as good.

Going back to the start of this post, they are now showing no stock. I don't know if this is temporary or if these conversion sets are now gone forever.

Compass also used to make a CCPM conversion for the Raptor30-50. I still have it if someones interested.
