Finally caught a break with marvelous weather and manageable gusts on a day off. Flew the Stearman several flights, love that it has stabilization, and maidened the Goldberg Falcon and the long awaited Ultrastick! Only a few pics and didn't do any video (forgot the cam).
One curious battery thin I have never seen before. Charged 4 3S 2200 mAh batteries at the same time (parallel? I can never remember). In all 4 batteries, one cell charged to only about 4v, the other full at 4.2v. This happened on all 4 batteries from the same charge. I decided not to fly with them so I didn't undevolt that one cell, ran them down on the bench while checking the voltage. At 3.8v on 2 cells, the third on was around 3.74v on each battery, so the gap narrowed. The IRs were all less than 6. They ran fine. I charged another set of 4, a different band, and they all charged normally. The affected batteries are about a year old. Curious if they won't charge properly again. Would be a bummer as in this eco no my I won't be replacing them anytime soon.
The gang is all here!
Little wheels and short nose make for easy flip over on landing when running into the clumpies at the end of the runway. The PT-19 flew like a charm! So love this plane. It's a shame Eflite moved away from these affordable balsa delights and sells overpriced foamies in their place.
The Falcon has flown, 4 flights. In the air 3-channel proved no problem for me to adjust to, just as John predicted. On the ground I kept trying to steer with the rudder instead of the ailerons. Of course I kept trying to coordinate my turns in the air. The Falcon has one issue that John is going to investigate. It has a constant hard right roll tendency that I had to control with left rudder. Wasn't able to trim it out with rudder in flight. The wing looks straight and not warped as far as I can tell, and the tail is straight. The Irvine 40 runs like a dream, no issues at all and pulled some nice vertical. I tried the 11x5 Scimitar, and it flew great, but losing just that 1/2 inch of ground clearance lead to one prop stall on the lumpy Geotex. It flies so well on the 10x6, may just get some Master Airscrew Scimitars in that size, but I want some more flight time with the 11x5 first. One thing about nitro is that shit coats this wing thick. I have a muffler extender, chose not to fly with it, but I just might. Also need to bring paper towels.
The tail looks good, in this pic the right side of the main wing looks a bit higher, maybe that's it? Maybe I do see a little warp, the ceiling edge on the right shows more underwing. I bet the wing does have a bit of warp and that would roll it right. The engine is rigged classic down and right so P-factor isn't an issue, and this roll tendency is constant. This made for challenging landings. Little dude is fast with both props. Once we get this roll tendency sorted, this will be a fun plane to fly!
I usually have bigger wheels on the Ultrastick, and am probably going back to them. Hit the taller grass and went right head over heels after a nice albeit floaty flaps landing. I am sooo happy with how it handled. Engine ran great, though it has a gravelly sound to combustion. This is the first time I have heard it without ear plugs. It was getting late what with all the waiting, I wanted another flight, but one of the leading edge wing pegs was a tad loose so I called it a day. Overall all, I am very, very happy. I got used to it running a long ways out, though I hope getting my cataracts done improves my clarity of vision. I feel a lot more comfortable flying the 26cc Pulse XT60 and the 30cc Sbach here. I will probably overfly the parking lot at the business next door on landings with the big boys but no one is ever there.... The Evo 10cc ran great, though I did lean out the low needle a bit more. The idle improved (it was a bit untrustworthy today until I learned it) as did acceleration to FOT. Pretty sure a gasser is going with me every trip to the field.
I call this day a wonderful win!
