Working on the rotor hubs for the tandem, this is the gimble assembly that will used on the front set of rotors.

Cheers, Ray K.

Not yet Paul, I drew out the basic structure, I should have some pics in a day or two, not much to it because it is a no-cal, just a fuselage, landing gear, two motor sticks, front rotor hub with gimble and fixed rear rotors. Fixed pitch and simple rotor hubs.

Cheers, Ray K.

On a side note the 500 could be redesigned to accept a 5 to 1 gear drive, this is something I will have to play with, working on the tandem for now.

I will be building the Piasecki this weekend if all goes well I will get the plans ready for you guys, no pulleys, just two motor sticks, a fuselage and two rotor hubs to make.

Cheers, Ray K.

I'd be in favor of the Piasecki HUP built in no-cal style.  No-cal comes out very light and the twin rotors should make for an interesting visual without the complexity of a built-up fuselage.

My 2p.

Well direct drive for this type of model just will not do, I am scraping this one and I will draw up the tandem for you guys to build.

Great job Ray...I'm looking forward to this cookup...so we will start things as you're ready to share the plans etc. with us.  Please don't feel any pressure at this point.  We're all enjoying following the development as you go.

I was able to fix the tail rotor issue, main pulley was slipping on shaft I was also able to increase the tail rotor DIA to 5 inches by removing the upper tail fin assembly, this was in the way and is not needed anyway it was just for looks, I made a smaller tail rotor pulley as well, now the model will hold position with no problems during testing, tomorrow I will try for flight. If all goes well I will tweak the plans and get them posted here, again direct drive, 1 to 1 requires quite a bit more power to get the main rotors up to flying speed.

Cheers, Ray K.

I've got a solution in mind for a Kaman design.  Will start on that.
