Does anyone have an email address or phone # for him? I also have a Tri-Gear KR-2 with A65 power and would like to pick his brain before I fly it. I would like to communicaate with anyone using A65/75 power.

A hard landing and gear compression can use up this clearance in a hurry. You should also being always trying to land on the mains first in tri-gear, and either 3 point or wheel land you choice on conventional. Greater clearance is needed for the conventional due to the possibility of having a tail high wheel landing, and hitting hard. The longer the gear legs, the more chance of greater compression/more there to flex, so also keep that in mind. I believe the Grove gear is taller. The primary purpose I have read about the prop reduction units are not to be able to run larger props, but to take the loads off the engine crankshaft, and isolate them to bearings designed more for that load. Secondarily you also slow prop, allowing it to operate more in its range of efficiency, and you multiply the TORQUE (not horsepower) of the engine due to the gained mechanical advantage (similar to a car's drive axle ring & pinion gears).

If it is a Great Plains shrink fit I would call Steve to see if it would be possible to have it pressed on prior to engine assembly. BUT--it has been a long time since I have done this so, guys, correct me if I am wrong--You only heat the hub to 450 degrees and it cools off very rapidly as you drive it onto the cold crank. I doubt if there is enough heat left to do any damage to the oil seal.

LOUIS, June 8, 2004 — Boeing [NYSE: BA] started assembling its Joint Unmanned Combat Air Systems (J-UCAS) X-45C aircraft today, loading the aft "carry-through” frame into a holding fixture inside the company’s St. Louis manufacturing facility. The 86-pound aluminum part, which spans the back end of the vehicle, will soon be mated with the two X-45 engine keels. Boeing previously built two X-45A vehicles, which are currently being flight-tested at Edwards Air Force Base, Calif. The much larger X-45C will be 39 feet long with a 49-foot wingspan and is scheduled for first flight in mid-2006. To help improve reliability, quality and also reduce costs, Boeing has incorporated lessons learned from building the “A” vehicles, as well as best practices from across the company, resulting in an extremely lean manufacturing process. “Thanks to advanced design and manufacturing techniques coupled with our lean processes, we expect the X-45C parts to come together easily and quickly,” said Darryl Davis, Boeing J-UCAS X-45 program manager. “On both the A and C vehicles, we’ve greatly reduced the amount of expensive hard tooling needed and we are using laser tracking for more efficient assembly.” The J-UCAS X-45 program is a Defense Advanced Research Projects Agency/U.S. Air Force/U.S. Navy/Boeing effort to demonstrate the technical feasibility, military utility and operational value of a networked system of unmanned air vehicles for both the Air Force and the Navy. Operational missions for the services may include suppression of enemy air defenses; deep strike; electronic attack; and intelligence, surveillance and reconnaissance. The X-45C vehicle will be able to cruise at 0.85 Mach, with a 4,500-pound payload, and fly at 40,000 feet with a mission radius of 1,300 nautical miles. A unit of The Boeing Company, Integrated Defense Systems is one of the world's largest space and defense businesses. Headquartered in St. Louis, Boeing Integrated Defense Systems is a $27 billion business. It provides systems solutions to its global military, government and commercial customers. It is a leading provider of intelligence, surveillance and reconnaissance; the world's largest military aircraft manufacturer; the world's largest satellite manufacturer and a leading provider of space-based communications; the primary systems integrator for U.S. missile defense; NASA's largest contractor; and a global leader in launch services. ===== Scott Cable KR-2S # 735 Wright City, MO s2cable1@yahoo.com __________________________________ Do you Yahoo!?

With a Tri-gear setup, what are my performance #'s and USEFULL load #'s likely to be if I get a KR2 in the air with a 1600 VW engine? I imagine it won't be great, but would an Ivo in-flight adjustable be a solution or a new engine option (or both) if I want higher performance #'s? Thanks in advance for your thoughts.
