To Julch: The Whopper is a hand full to get in the air!

I wrote a review that appeared in January 1991 RC Modeler Mag.

Head speed is everything! The long, clark Y airfoil blades work the best. Somehow I never broke these blades on a take off tip over.

The gentleman that suggested a string to hold back the Wopper on initial head run up is a good idea.

If you can see rotor blades during a take off run, STOP! You don't have head speed.

15 mph head wind is a great help to take off in.

My Wopper was "Sky tached" @ 800 rpm.

Blades should be tight enough in the blade holders so as not to fall under their own weight when you hold the nose of the Whopper up to check for a lean engine carb. setting.

In flight, RUDDER must be used for turns. Bank and Yank does not work. Cyclic roll only and the Whopper will slide. Use the cyclic roll to control the bank angle and the rudder to turn.

Landing is a piece of cake. Reduce power and establish a desent rate. (slight nose up attitude) Adjust power to streach glide. In a strong head wind hovering is possible, but keep from flying backwards, especially during a landing.

Let me know if I can help further.
