[NSRCA-discussion] Osiris, was Weather

Fri May 27 05:50:50 AKDT 2011

I think that if someone doesn't have the 10s packs to split up, they would be better off with the 50-16s on a 6s 4000 pack.  It gives 1600 watts at 71 amps and the weight is the same as a 5s 5000 pack.  With a 16x12.

Yes , I'm running the A50-12S and the 16x10E.   In a full on head wind it probably doesn't have the pure speed I would like, but overall, I'm pretty happy with the speed envelope.   

I like the tractor effect that the 16 has.  The up lines are much more positive than they were with the 15.

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.

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.

I vowed to retire the Temptation and fly electric this year.  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.

The 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.

Now 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.

I 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!!! Mike
