Roo Hopping
Pete & Todd:
Screwing with the incidence won't do it. To really damp and even stop the hop 2 things:
1. Get the C.G. right on dry, and then try not to land with too much fuel. The Roo lands much nicer with the C.G. as far aft as you can get it for landing. Allows it slow down better and not bang down on the nose gear oleo spring.
2. Learned a little trick from Don Hoffman who flys a Roo with a RAM 750 on it. Lots of flights. He's a member of the Sarasota Club.
What he does is put on some brake for landing, like just before it starts to really grab. He uses a Smooth Stop with BVM W/B.
It also works with UP-6 with Glennis W/B or BVM W/B, but not with Smooth Stop and Glennis since even at 1/4 ON with a Smooth Stop(high pressure system), there is enough pressure to totally lock up Glennis Brakes which are a low pressure system. 40 PSI will lock them up.
The results are amazing. The Roos and HotSpots stick like glue--and the nice thing is that you probably use up a little more rubber over time, but it does not produce flat spots if they are set right. He uses one of the rotaries on the side to set the brakes. Don rarely uses up more than 1/3 of the 700 ft. Sarasota runway, usually allot less. If you have it set right, absolutely no skidding either.
My buddy and I fly our HotSpots and F-15 off grass fields, and one of our fields is only 250ft long. Using the preset, I can regularly get it stopped in 100 feet or less from touchdown point.
This really isn't new. BV and allot of other top flyers use a little landing brake as well on the big scale jets. I think BV has it posted somewhere on his website.
