1500.0. "Genesis HLG" by KBOMFG::KNOERLE () Fri Mar 26 1993 02:47

    
    Now that I've built and flown the Genesis HLG a few words to both.
    The building was rather uneventful. The fuselage is a very simple
    construction with no hickups.
    The wings take more attention due to the (poor) quality of the ribs.
    The problem with the ribs are 1) the lengths are not correct, some are
    too short and others are too long. 2) some are significantly smaller in
    height at the leading edge (read: airfoil not the same) 3) the cutouts
    for the spars vary in size and location. 
    Other than that no problems encountered. 
    I didn't like the way the wing halves where glued together. I added top
    sheeting on the center section (the plan called for bottom sheeting
    only) and even glassed it. Now I'm confident the wing stays together.
    
    For covering I used paper. Be very carefull to get the correct warp in.
    For this reason I've choosen paper, once finished it won't stretch
    (hopefully). If you won't have the warp (?) at the LE of the wingtip of
    1/2 inch it probably won't fly correct (i.e. tip stall - Kay ?) 
    Flying wings do need this (okay, the Gremlin doesn't....)
    
    
    More on flying in the next note.

1500.1	flying the Genesis at the slope	KBOMFG::KNOERLE	`Fri Mar 26 1993 03:02`	30
	Now for flying: I didn't need any lead nor major equipment move to get the CG where it's supposed to be. I've choosen the configuration with the two servos in front, one for elevator and one for rudder. No ailerons. Then the receiver and the battery (180mA - 250mA ?) to the rear side of this compartment. The tow hooks position as in the plan didn't work for me, the poor thing went straight up and popped out. I needed the succesive approximation method (simply called trial and error) to get the plane's behavior on the high start as it should be. If anyone's interested I'll measure it. The position is critical to 1/16th of an inch. You have to see all those holes.... One thing I have to say : this plane flew perfect from the very first moment. It was on a small slope with light wind. After tossing (still with certain respect) it flew straight. The turns are a must to see. The ruder cranks the plane and with the elevator you can fly super turns. No need at all for ailerons. I flew approx. one hour the first time and really enjoyd it. I can slowly pull full up elevator without any tip stall tendency ! It just takes the nose down gradually to get the right speed what is very slow. The landings at the slope I tried from each direction - pice o'cake. This easy handling is caused by the warp of the wing. Bernd
1500.2	handlaunching the Genesis	KBOMFG::KNOERLE	`Fri Mar 26 1993 03:29`	20
	Okay, the box said HLG, how is it doingh in this arena ? As I expected it might not be the most competitive plane here. Several reasons I think. 1) it has two turbulator spars that slow down the plane. 2) The wing warp might cause more drag in high speeds 3) the airfoil isn't real thin. When throwing you need to be fast on the elevator trim. I installed a push botton on the tx that trims the elevator down when pressing. When I throw it does a nice arc to level flight now. As stated before it is very manoeuvrable (sp ???) and easy to handle. Performance wise I cannot say yet how it compares with others. I get somewhere between 18 and 22 seconds without thermals. What do you get in dead air ? I heart that 40 - 60 seconds might be achivable with good HLGs ? What does your experience say ? I like to know .... Bernd
