HelicopterCentury Radikal G20-30 N640 Hawk Predator › need to double check with the Century "pros" no pun intended

i have been doing alot of research for my upcoming winter project and i just want to double check a few things and maybe get a heads up if i am heading into trouble.

i am planning on building an electric Airwolf 50. the mechanics will be the Hawk Pro with the CCPM conversion kit (so i can have room up front for a scale cockpit). i will be using a Neu motor and will fabricate the motor mount, batteries will be two Tanic 4S2P 4900's run in series to give 8S2P. i am still a little unsure about the pinnion gear to use but something in the 20-24 tooth range seem popular.

my research tells me that the mechanics and the tailboom should all fit well without alot of cutting and hacking

also, the CCPM conversion will fit in the fuse and give me the room i need up front.

if there is a MAJOR oversight on my behalf, please chime in as i would hate to have to return something because it was bought in error.

thanks ,

Are you 100% sure?
I've got the Bell 222 with the Falcon mechanics, and I'm quite sure that mine hasn't enough room for the CCPM conversion.

I am not sure on the CCPM

I would give Century a direct call. The airwolf 50 is a new shell so it may have been made for the ECCPM ? With the high servos and low overhead of the wolf like a 222 I am sure the old molds would not work.

Most if the scale fuses were designed for the scale mech set that is basicaly a hawk/falcon.

In a scale the hawk non ECCMP works great. In fact I run it in my 3D heli and do not miss the CCPM except the small interaction at extremes. You will never use those pitches -6/10 in a scale.

Drop them a line. Antonio has lots of exsperience so he will know right off.

Darren,, I can't say much about what your asking, my friend has the Funkey 222 but I haven't had my hands inside it,, but there was a guy that put photos on RR of his electric converted Century Bell 47, to allow for a scale cockpit he made his own lower frames, this allowed him to put his radio and batteries where the stock fuel tank was mounted, servos were mounted in his new hand made lower frames, it seamed to be a very simple conversion,,, I will try to find the post, but give me a while..

well here is one, but it's not the one I was thinking about, this one uses the stock lower frames, as I said the one I was talking about had hand made lower frames..

OK,,

here is the heli I was thinking of, although it's a glow heli you could do something like this and convert it to E power, notice were he mounted the Aileron servo,,

hi jim, thanks for the help. i looked at the pictures you sent. i did contact Antonio and all he told me was that the Raven CCPM would NOT work. this he was sure of, but didn't know (or didn't comment) on whether the Hawk CCPM would work.

he suggested that i post something on RR to see if anyone had any suggestions.

i don't necessarily want to spend the $90 on the CCPM conversion kit if it isn't going to work. the pictures you sent with the Bell 47G look interesting and unless someone else tells me for SURE that it will fit, i will try to replicate what you showed in the picts.

i just want to be able to put a semi-scale cockpit in the Airwolf, not necessarily to improve the performance.

thanks for the help Jim and everyone else.

The servos will bind, because the configuration of the raven differs from the other eCCPM configuration. It has a servo mounting attached to the side of the frame, from the push and pull type ECCPM configuration to where the servos are installed into the frame.

If you want to mount the Raven into a fuselage, the Hughes 500D or 500E, even the Robinson 22 is an execelent choice.

I have read a side eCCPM conversion, but from what I have read it is for the Hawk Pro.

thanks genovia for the input but i don't want to mount a Raven in a scale fuse. i was just commenting on what Antonio was telling me. i am just looking for the simplest way to get a cockpit in an Airwolf 50. so far "Wasp" has the best suggestion and unless someone else shows me otherwise i will be using the Hawk Pro mechanics, converting it to electric power and then modifying the stock side frames to give me the space i need up front for the cockpit. the CCPM conversion was an idea that someone else told me about that may have worked but from what others are saying here it seems like a waste of money as the spacing is too tight in the fuse.

May I suggest that you post the question here, in the scale forum here on RR.

http://www.runryder.com/helicopter/f43p1/

Maybe someone there will have tried it or something similar.

Note, the CCPM Hawk Pro conversion parts are directly from the Raven, so the clearance would be the same. If it will not clear for the Raven, it would not clear for the Hawk Pro with the conversion.

Darren,

Aside from Century's eCCPM config.will not work, it will only work on a few fuselage. If you are not going that route, I would suggest in mounting your mec. as is. As far as conversions go. I have seen an "E" Hawk installed into a bell 222. Check out the thread "wutcha got" and you will see what I am talking about.

If you want to go CCPM use Steve H's "peregrine" conversion. Is is substantially narrower than the Raven conversion and not hard to build. It fit in my airwolf 50 notro with no problems.

not going to help in his original intent

The intent was to move the servos back to put in a scale cockpit area.
The pedigrin still has the servos in the front mount.

I think he was looking at ccpm for this reason.

The pedirin removes the interaction of cyclic bells on the pitch lever it does do this but introduces swash interaction due to the different geometry between the elevator bell arm and ail/pitch bell cranks. They are not 1 to 1 even so on top and bottom the elevator servo needs to be adjusted to match.
Not a big deal and it makes for a better handle on the heli. ECCPM also gives you this feel.

The ECCPM also raises the CG over the pedigrin with the servos higher so the heli 3D flies and rolls more on center.
