[NSRCA-discussion] Off the wall....

[Bob Richards]

A few years back (maybe 10?), a guy showed up at the field with a recent low-cost heli that was .40 powered, but fixed pitch. The local heli jocks would not touch it, but one of them remembered that I had flown such a beast way back in the 70s. I helped the guy out and got him flying. It was much easier than I remembered, but it DID have a gyro. :-)
 
One thing I did to tame down the tail rotor on the old non-gyro fixed pitch helis was to glue a large cardboard disk on the end of a wooden dowel, and tape that to the tail boom with the disk sticking out past the tail rotor. Did not stop the tail from swinging, but damped the motion significantly. In a slight headwind it would weathervane to the point that not much tail rotor control was needed. 
 
I also switched to a single-stick transmitter (Proline). Tells you how long ago THAT was. :-)  Made the tail rotor input easier, IMHO.

I flew the Hughes 300 / O&R in the '70's. No mixing, no collective, no gyro, no power - yet it looked like a heli and sure taught one to use the rudder thumb!

I have a .60 Shark I'm in the middle of rebuilding. Had one way back. I also have two NIB Hughes 300's with the O&R engine. Should be fun to put those together!

I had one of those, too. Engine never put out enough power, so I replaced it with the .60 conversion. I still have the remains of that copter :-)

I had a Dubro Shark helicopter in the early 1970’s with an O&R Gasoline engine with a pull-start.  It did look like a chainsaw engine.
