Hey Dan.
I dont think that tail bell crank/mount will fit on the stock Century helis. I designed that for the Reactor conversion kit. I can make one for the stock Pmax/Gasser if you would like. The arm itself is a bell mixer from the head. The mount is custom machined by us. The problem is that the rudder servo is in a different spot on the conversion so there may be alignment issues with the control rod that goes from the servo to the arm. This is all speculation because I haven't tried that tail set-up on the stock Century helis.

Well I have the YS 80 so the throttle is on the opposite side. I will take whatever you got because it has got to be better than this.
I just got my Predator yesterday, I will be converting this kit. I will assemble the stock frames to use for mock-up. I will check and see if the parts that I already have made will work, if not I will make a new bracket for you. Not to worry Dan, we will get you fixed up. Of course It will take a week or so if I have to design a new bracket. I will keep you posted.
Mike
By the way, what you currently have is "wacked" but I understand your deal with the throttle arm being on the oppisite side as the exhaust. And I understand that there is not a Century solution to the problem, Have you tried a YS 61 carb? I have one that I will send you if you want to try it. I think the carb is the same. I know it will bolt on and I am sure it will supply enough fuel for the 80. You should be using the YS 61 throttle valve anyway, (the part of the carb that turns) it gives much more power that the stock YS 80 throttle valve. That is an old Gary Wright trick. If you want the carb let me know, I am not sure if I have the throttle valve though. I think I used them in my YS 80s which are long gone.
Mike
Dan,
Just an FYI: That YS 80 does have the updated throttle barrel from PS.
Thanks

I need to talk with Hot Shot Charlie or whomever put the Predator together. It was more center line than it is now... but I have no close up pictures on how exactly it was routed. The original (or modified) pieces to the helicopter are planted somewhere on the field at Blacksheep :lol:

Tell us more about that heli in the first pic. Looks like a major rework of the Pred frames. Much like the MA "stratus" was to the fury ??

Well if you cant figure it out, let me know and I will get you fixed up. I have a few ideas on the linkage, I will see what I can come up with. Good to hear you have the updated throttle barrel, it really makes a difference.
Mike
I will take some pictures of the Reactor as I build it and post them in a new thread. Like I was saying before I just got a new predator kit and I will be building it over the next 4-5 days. It is a Century Predator based conversion kit. It has a rear mounted fuel tank and uses the Century CCPM system except for the elevator servo is behind the mainshaft, it is mounted to the boom grip. There was alot of effort put into raising the center of gravity of this machine. Everything is raised as high as possible to help eliminate the pengilum effect during 3D maneuvers. Even the canopy was raised an inch (average canopy is 6oz.) Another nice feature is the break-away canopy mounts. These small carbon fiber parts are designed to break, leaving the frames unharmed. I also put alot of design effort into making the machine very durable. It has already sustained a hard crash on tail/head without any main frame damage. As a matter of fact none of the conversion parts were damaged at all. And to top it all off the prototype weighs in at less than 10 pounds. I think it was 9 lb 14oz ready to fly without fuel, but I am not sure as we weighed it many times throughout the build of the prototype. It will be called the Reactor and will be manufactured and distributed by Prolite R/C Helicopters, which is a division of Carbon Fiber R/C Parts.com This machine is still in the testing phase, but so far so good. I hope to begin production in 6-8 weeks.
If you have any other questions I will be starting a new thread in a few days.
Mike
Dan,
I think that is my old bird that I built. I was thinking that I had the geometry a little better than what is showing in the pic. I did that conversion way before Century came out with their's as I wanted the tail servo up front! I'll try to see if I can dig up some pics of it. Let me know if you have any more questions.
Thanks
DanW
Dan,
I found a pic of the original setup. You have the arm upsidedown the long half goes down and the short half goes up. Also the control ball on top goes on the inside or frame side.
Look at the pic of the orginal setup and compare it to the way it is now.

I hope this helps!

Can I ask what that black plastic arm is off of? I was just wondering because It looks like it might work on a project I have been working on. It looks like a raptor mixing arm. What is the distance from the center of the center bearing to the center of the ball on each side. Please let me know.
Mike
Mike,
It was a Fury tail rotor mixing arm 115-38.
I don't have one to measure anymore but maybe Dan can measure the one on his Predator.
Thanks
DanW
I can't wait to hear more about the Reactor!
And what is the the Century Frestyle Predator update???
Their site says details coming - going by the 3D Pro and the Swift
that could mean any time in the next 18 months... :lol:

Thanks Dan! I tried it that way but was running into either the tail fin or the boom supports with the control rod. Do you remember if you modified anything else in back to keep it from binding?
I learned a valuable lesson. Take LOTS of pictures of your helicopter before you crash it.

That reactor is tough, I saw one PLANTED at B-Ham and the frames and carbon skids did not have a scratch on them. :shock:
Arrgg, Will, you're gonna make me loose sleep waiting for this package :lol:
This could give the predator a new lease of life...
Thanks for the feedback man!

If Mike can get it competitively priced, I would bet he can sell a bunch of the conversions. From what I saw, it greatly simplifies access to the innards as well as lightens and stiffens up the machine a good bit.

Damn skippy! If it was a BIT cheaper I would have ordered on the spot. Still under consideration...
Also if he could work with Century on the other parts you would need for a FULL kit. That would be a option too.
Fantasic pictures - looks great!
If Mike can get it priced right, my partner won't kill me :oops:

Thanks Jafa, the lighting sucked, it was misting at the time a little bit and very overcast. Everybody was wrenching and BS'ing and Bobby Smith was installing 2100 3s Lipo packs ina couple of 9Z TX's at the time the pics were taken.
Wow I hi-jacked Dans thread. Sorry man. I knew I should have started another thread. The pictures of the bare assembled frames are the updated frames. That is what I am building right now. I should be able to test fly it this weekend. These machines are real easy to work on. I cant belive how fast it is building.
I have been working on the price guys. My goal is to get the pricing in line with the other conversion kits that are currently available. I am going to do a standard kit and an SE. The SE will include the carbon landing gear and carbon 3D fins and head button. The price mentioned at Bham was for the SE version.(459.00) There are provisions to use the stock landing gear if you want. The standard kit will be about 80.00 dollars cheaper than the SE. I might be able to shave a little more if I can find someone to machine my aluminum parts cheaper. I will keep working to try to lower the price even more.
