[NSRCA-discussion] Osiris, was Weather

[Bob Kane]

As soon as I get a chance to pull data with the Castle Link I will let you know.

Mine was about 85 amps on the ground.

When I ran the 16x10 I found I was pulling over 90 amps static. What does it drop down to in-flight?

I know you addressed this to Mark, but I can answer parts of it:

Yes, Hacker A50-12s
APC 16X10E

I was running the Castle ICE 75 but am in the process of swapping it out for an ICE Lite 100. The ESC would go into over-current on the ground while trying to set the high throttle (4 seconds) using auto calibrating throttle. I found I could use high throttle for the required 4 seconds while on my downwind pass after take-off.  The real answer was to go to fixed throttle end-points.

I also could not find any suitable 15X12E prop.  I really don't have enough time on the plane for a final verdict on speed with the 16X10. Muncie was windy all weekend, and the plane seemed to have enough speed for my needs, BUT (yes time for the big but)

I did find the need to set the throttle curve with a lot of what amounts to reverse
 exponential.  My left thumb throttle settings from years of YS powered planes were too low when exiting maneuvers, so the plane was going too slow.  My YS setups were essentially at full power by 2/3 stick with a lot of power below half stick. The default electric was truly a straight line and and I found myself needing to push harder on the stick to get the speed I needed. The speed was there, but concentrated on the upper end of the stick. I kept playing with the throttle curve and now am at a pretty aggressive reverse expo to get that YS "feel".

Mark,  Are you running the A50-12S ? I am running APC 16x10E, but it seems to lack speed in wind.I am even thinking about running APC 15x12 (glow prop) as I can’t find any higher pitch on 15” diameter.  Only thing available is Master Airscrew which I don’t even touch.

 Weather  I would have to agree with Bob.  It's very capable plane.  My son is currently competing with it in Intermediate and is not suffering from the slightly smaller size.   It's flight characteristic fully mimic a 2m plane and it handles the wind extremely well.  I would encourage anyone to try one.   I've flown it through both P-11 and F-11 without any shortcomings.  Power on a 5s pack is abundant (with a 16x10 prop...the 15x10 is good, but doesn't mimic the type of power the 2m planes have) giving you full vertical lines and plenty at the top.  I've been extremely impressed with it.     I would say for anyone wanting to get started in Pattern, it's the perfect first plane to fly from Sportsman through
 Advanced.  It flies masters well, but at that level you're starting to meld pilot skill with overall presentation and of course, a 2M does present slightly better.  I say slightly because this plane really does present like a "small" 2m plane.  It's also a great practice plane for learning new maneuvers without putting as much $$ at risk.  I got my sons in the air for about $700 all up.    -MarkMark AtwoodParagon Consulting,

I have an Integral in white still new in the box but for a lot of reasons I have not started it yet.   I saw Sean Atwood's Osiris at the end of last season and decided it would work as a competition plane, at least for me*.  The beauty of the Osiris is it flies on exactly half of a full F3A battery, a 5S 5000mAH pack, so any investment in batteries can be carried
 over to a full size F3A plane.

* I am a long way away from being a top tier pilot. At last week's D4 season opener in Muncie, no one made the comment that the Osiris was holding me back and I would have scored better with a full 2M plane. ;)

In all seriousness, the plane performs very well and is a winner in the right hands.

Date: Thursday, May 26, 2011, 1:29 PMThe Osiris is very popular. It has to be very good.  The question:  Are you using for practicing only or is going to be your contest plane? OK.  Waiting for Charlie.  I hope that he gets good news for us.

Subject: Re: [NSRCA-discussion] WeatherNow that I have 10 flights on the Osiris (4 test flights, 6 contest rounds) I'm taking advantage of the bad weather to change out the ESC for a lighter, higher current
 version, and moving back to help adjust the CG rearward. The rain makes looking at it sit on the bench more bearable.

Date: Thursday, May 26, 2011, 12:28 PMI don't know about where ya'll live but I have to tell you this spring is far and away the worst weather I have ever seen. Today we have 44 degrees rain and 30mph winds. Yesterday we had 2 inches of rain in a short period of time. Its just miserable!!!
