    Maybe, maybe not. Do you have a thrust bearing? A cde 44 for example would work no problem.....

    You would be stretching the wind load capacity of the CDE-44 epeically in a northern climate, Ham IV is the answer. You have a huge investment, call Norm's Rotor Service heck of a nice guy information is free.

    I use a g800sa yeasu and it works great for my 5 element. You can get them new for around 400 bucks.

    I used a CDE 44 and a thrust bearing on a Moonraker IV here in Chicago weather.

    Just barely worked....

    Lasted 3 or 4 years, and then had to be rebuilt.

    Went with a Ham II after that.

    You are right HiDef.. I had to look up the models from back then in 1970...

    The first one that failed was a CDR-44 (The old control box type).

    The better one I put in later was a Ham-M (Had no problems with that..).

    I had the Moonraker on a 20' piece of 2" heavy wall galvanized pipe.

    High winds would spin that CDR-44 rotor occasionally....

    Many hammy hambone rotors are overpriced junk.

    I hate them with a passion.

    Real rotors like the old Telrex or a prop pitch are a poor man's dream.

    I remember when the "Overseas" rotors first started to hit the market...

    I thought they were overpriced junk at the time...

    Now they seem like bargains....

    A lot of guys around here in the 80's and 90's were buying parts from Howard VanValzah to keep their CDR/CDE/Telex rotors running, so they did not have to buy the foreign ones...

    I've turned a 30' 5 element with a cd 44 rotor before, and Ive turned 4 element beams with the plastic channel master rotors and never had one break yet. The worst wind we had was about 60 mph and neither rotors broke. With the channel master I had 15' of mast pipe sticking out the top.

    Ive been running the cd44 old style rotor on a little tower for quite some time now with a 4 element on top and it seems to work just fine.

    I have a modified Super Laser 500 up that has been stretched out to a 60 foot boom with 10 flatside elements and I have been using a Ham IV the past 12 years without a problem ever...

    Way back in the day, as a young one, I had moonraker 4's on with a 5 ft tripod on my parents roof. Used a radio shack TV antenna rotor with no problems. However, Quads have a very high windload as opposed to yagi's. I would buy a real rotor. Last, the reason I was looking up rotors is that I will put up 6 or 7 flat when the weather breaks (Detroit). The research I read on the Ham sites is that the American CDE/Hygain rotors, including the heavy duty Tailtwister do NOT hold up well with the Ham beams even when under the windload ratings. I am wondering what the big boys with big beams are using and is it working for you.
