[NSRCA-discussion] 3D Hobby Shop Osiris

[Atwood, Mark]

Hey All,
I'm not normally one to "gush" over a new product but given all the talk lately about getting new people into pattern, making weight, etc, I wanted to relay the great experience I've just had with the new Osiris from 3D Hobby Shop (no, I'm not affiliated with them in ANY way).   Those in D4 are aware that my 13 yr old son has recently joined me in flying pattern (Big grin here...I've been waiting 13 years for this) and he's been competing a little bit (2 contests) in sportsman with a 50" AJ Slick.  Flying pretty well but getting his butt handed to him in any sort of wind as the slick only weighs about 2lbs and is really more of a 3D plane.

Anyhow, for his 14th birthday last week I bought him one of the new Osiris 62" pattern planes that are designed for a 5S pack.  I figured this would be perfect.  He can use my older packs, and we can basically share batteries which will further extend my investment in 5s packs.
The plane arrived last week and I have to say, has blown us away.  The kit is immaculate.  It took 4 hrs from start to air to get it ready.  EVERYTHING is done.  The wheels and pants are already mounted to the landing gear struts...4 screws and you're done mounting the gear.  The canopy is already mounted.  Control horns come pre-glued in AND everything is straight. The only real "work" is mounting the stab which took about 30 minutes because dad is anal about alignment.  But the cut out was dead nuts on, and it required zero shimming.   After that, it was drop in your radio gear and go fly.   All of the hardware supplied was good quality ball links and pull pull hardware.  I didn't replace anything (which is extremely unusual for me).
So all of that was a VERY pleasant surprise as I anticipated more than a few evenings to get his new plane ready to fly.

Flying it was even a bigger surprise.  For a 62" plane...basically equivalent to a .60 sized glow plane (think Kaos 60) it was unbelievable.  It's got the design and moments of a current F3A plane.  The side area is large, wing area is moderate, with tapered tips Ala the Spark.  I was able to trim the plane completely in about 5 flights.  The suggested CG was slightly tail heavy for my liking, but after moving that forward slightly everything fell into place.  Mixing was moderate (less than 5% anywhere), and there was no need for any difficult adjustments like wing incidents or motor offsets.
I then flew the FAI P pattern and F pattern without any difficulties through the rolling figure M (other than my lack of piloting ability) as well as all of the snaps in the F sequence.   Amazing.
To hand this over to my son for the sportsman sequence seemed like a crime (though he was growing rather tired of ME flying "HIS" airplane under the guise of "I'm still trimming it".
All up, I'd say I have less than $700 in this airplane with kit/motor/ESC/Servos, and less than 4 hrs on the ground from box to air.   I have not weighed it, but I'm guessing it's in the 6-7lbs range.    I will be bringing the plane to the RCCD contest in Detroit this weekend as well as my son campaigning with it at the D4 Champs in Cinci next weekend if anyone would like to see/fly it.

I really think we have a GREAT option for people wanting to try electric pattern at almost any level.  Is it an FAI plane?? No...  But it flies like one.  Just doesn't have the size and presentation.   But it's VERY VERY capable in Sportsman and Intermediate, and will out fly most of the competitors up through advanced.
I'm encouraged that we now have several great options... The Osiris, the Wind S 110, and others for people to get started with, without spending a fortune.

BTW- Equipment in the plane.   Hacker A50-12S/ Castle Ice 100/ Airtronics 94761's (mini with 65oz/in of torque) on Aileron and elevators and a 94773 (Full size 110oz/in of torque) on Rudder.
Flies a good 7min on a 5000mah 5S pack.
