RE: 2012 Hog Bipe rides again
he pile of parts is beginning to look like an airplane! All linkages and aileron interconnects are installed and await final alignment. My Airtronics SD-10G has arrived along with my repaired Saito fa100t from Horizon Services. Debating if i am going to stick it on a test stand before instalation. Should be good to go with enough run time on it from the previous installation to be settled down and dependable. We shall see. Will install the new Airtronics reciever in another airplane this morning to get some flight on it before i trust a new build to it.
Have had quite a round with a H9 digital incidence meter. Very nice unit that appears to be extremely accurate They have a little battery just over 1/2 inch tall (15mm) and 3/8 inch in dia. (10) mm for power. Rated at 6v and 11 amps according to the battery label (whatever 11 amps means....never ran across numbers like that.). There is no auto off feature in the circuitry of the unit and the little digital inclinometers draw a heck of a lot of current apparently. Forget and leave the switch on, which i soon did, and the little battery is toast in short order. Found numerous references on the net regarding the problem. And all kinds pain and agony finding a replacement for the cheezy battery shorty of ordering it from Hanger 9. Folks have found the battery if they have a deticated camera store near by that carries these little odd balls. I don't have that luxury. The nearest possible source is a deticated battery store an hour drive from here. Way to go H9! Got a nice little 'Dollar Catcher' going on with part number HAN197.
I got to thinking 6v huh......well i have a new 6v 2000ma hump flight pack sitting here.....and a soldering iron and a female servo lead. Solder a pigtail to the battery contacts, hook it up and see and see what happens. And it works....beautifully! None of the smoke has leaked out and i see no reason that it will. 6v is 6v, no matter where it comes from, weather it is from a huge U boat submarine battery or a little cheezy camera style battery from China. Let the power hungry little rascal chew on the current from a good reciever pack and let it see if it can run it down!!! The only down side i can see is putting up with the wiring while running the unit. That and the unit looses calibration when the battery is removed, requiring a recalibration whenever the battery is plugged into the pigtail. No big deal....
Got a good handle on the build incidences last night using the new setup. Lower wing is dead on, within .1 degree. Top wing is at .3 degree negative incidence , and the horizontal stab is at .3 nose down. Have not checked thrust angle yet which i doubt i will hassle with checking because of the way the firewall locks into the fuselage structure.
