EXCITING NEWS FOR ULTRACRUISER BUILDERS AND OWNERS (7 LBS. SAVINGS)
A while back we had built an Ultracruiser for a gentleman that wanted a clipped wing so he could have a faster roll rate. The wing was 30 inches shorter overall. In otherwords we left the last "bay" off of both outer panels. He also wanted the 45 hp engine. The plane flew 95 mph but stalled about 32 mph. The other interesting thing is that taking out the 30 inches knocked a little over 7 pounds off the weight of the plane. So we got to thinking about how to get the stall speed down. We recalled that other builders that had not set their ailerons correctly could not get the top speed that others were getting. As you know you need to set the apex of the trailing edge of the aileron about 3/8" above a straight edge that runs from the bottom spar to the aft edge of the bottom skin. If you set the aileron so its bottom surface is flat on that straight edge you are effectively flying around with the "flaps" down. Which turned out to be the result for the guys not getting the desired top speed. Once they set there ailerons correctly they picked up 5 to 6 mph. We had not tested the stall speed of a plane that had the ailerons set like that but figured it would lower the stall speed.
Well today (4/9/09) we had a chance to test it and we were right. With the clipped wing and the ailerons "drooped" the stall speed is 28 mph. It did also lower the top speed to 90 mph instead of 95 mph.
WE ARE NOW AN AIRCRAFT SPRUCE DEALER
This means that we may be able to pass on some savings to you. Since we are a dealer we get a discount on various items (not all items) and the discount amount varies from one item to another. So if you were going to place an order to Aircraft Spruce that was a few hundred dollars you may want to give us a call. If we can we will pass some savings on to you. Doing a back of the envelope calculation it appears it may be viable for larger orders, meaning low hundreds and higher. Also, the items would be dropped shipped right from Aircraft Spruce. So if you can wait to get a quote from us it may save you some money.
NEW BUILDING METHOD FOR ULTRACRUISERS
We currently have the fuselage skins set up so that they can be printed on mylar film. Mylar unlike paper is dimensionally stable. So what this means is that we can print the kit parts (the laser cut parts) full size on mylar. So you could place the mylar patterns on a blank sheet of aluminum and cut it out and drill the holes in the sheet based on the mylar pattern. You would then essentially end up with a kit part. What this means is that you would not have to build the beam and mount the bulkheads on the beam. Because like the kit parts the holes are in the skins, the build up of the fuselage is based on the already drilled and proved out holes that are in the skins.
The other advantage to building this way, is that if you should in the future suffer damage to the aircraft you could reproduce the damaged part by unrolling your mylar prints and making a new part. There is one thing to consider to build this way. The skin patterns were produce using our bulkhead form blocks. So if you still want to build your own bulkheads you would have to extend the fuselage skin edges and develop your own hole layouts for the overlap area on the bottom of the fuselage. In other words if you buy our bulkhead set you just make the skins to the pattern. If you make your own bulkheads the above mentioned method is needed because your formblocks may be 1/8" larger in circumference which would mean the predrilled skin holes may not line up on the bottom. We plan to extend this mylar method to the wing skins also. Mylar fuselage patterns are $250.00. If you have any questions give us a call.
STAY TUNED FOR MORE BUILDING AIDS
We are planning a few more building aids for the near future. We are trying to elimate the fear of working with sheetmetal.
We are located at the Williams County Airport. For more information on the Williams Count Airport, visit them online at www.williamscountyairport.com
Don't forget to visit the discussion forums as this area also contains much information when it comes to building one of our planes.
