yeah,
Me too. Can't wait to hear of the problems cause mine flies like an arrow.

Looking at batteries for my new 62" Osiris. i have become a big fan of GensAce Lipo's, BTW I have a box full of TP 65c batts but for the Osiris I am running AJ's setup and will be practicing and flying F3A pattern. Period. GensAce has a lot of 5s solutions, here is the short list:

25C 5300 625g 64$
30c 5300 630g 68$
60c 4800 670g 83$
60c 5000 670g 92$
60c 5300 676g 109$

So if 25c is enough, and AJ said it was in his video, then the 25c 5300 looks hard to beat, light and cheap. But the 30c is only 5$ and 5g heavier so...
If I go bigger I can't see paying 109$ for 300mAh so that means the 60c 5000 at 92$ and 670g. I have to haul 45g extra to go from 25c to 60c.
Any advice would be great and this with a eye to someday running a 2m Osiris on two of these packs. Motor is the recommended Hacker A50-12s/16x10APC/Ice Light 100. Thanks

Personally I love Sky 6S 5000mah 40C packs, and they are cheap.

Joe Smith got me to try them. If they work for him, they will work for anyone. That dude flies ALOT!

Does anyone know of a non-ARF balsa kit for a plane kinda like the Orisis 62? I'd like to build one.

Check out the Pattern threads on RCUniverse. There are kits that competitors have designed.

Ready to pull the trigger on an Osiris order. Just for fun, I put the A50-12L, 5S-4000, and 16x10 into the eCalc web tool. The max current comes out at 35A and max power at 620 W. This seems way low compared to what everyone described. What am I doing wrong?

A50-16S, 6s5000mah, APC 17x10. That is the way to go. I started with your potential setup, and then I flew 112 flights on 6S.

Neko,
Try the Hacker A50-12s V2 492 Kv on the Motor calc, Using either a 15 X 8 or a 15 X 10 on 5s 5000mAh. Instead of the A50-12L 348 Kv.

I fly mine on a Hyperion 4035-10 405 Kv on 6s using a APC 16 X 10 Or a 17 X 10
Prop and it's a beast on that set-up.

J

If you go with A50-12s & 5s, try 16x10E for normal flying.
On strong wind day, I use 16x12E cut down to 15.25x12 (approximately 10mm cut off on both sides)
Pulls about 73 amp. A lot better than 15x10 with broad range of speed.
30% brake seems to work well on down line.

Check the Horizontal Stab incidence before gluing. Set it to 0 or parallel to the fuse top.
It wil be a better flying plane.

Good tip on the stab incidence, thanks! I find it hard to believe AJ's setup is not optimal but it is too late now, I got the motor and prop he recommends in his video. I also got a couple GensAce 30c 5s 5300 packs and they are amazingly light and compact. And Johnnyrocco I can't believe you swapped your avatar, I was just going to get my picture taken playing my guitar! Ah well, cool heli though

The Osiris is a nice flying pattern plane but you need to check the incidences of the wing and horizontal stab. Mine needed adjustment out of the box.
PatternFlyer helped me with suggestions for the incidences. Zero incidence for the horizontal stab and +.5 for the wings.
Once I made the incidence adjustments very little trimming was needed. I set the CG at 7 inches as recommended by AJ in his video.

Hmm, this is the first time I read about the need for setting up the incidence on the Osiris. Was there a problem with the model or is it based on personal preferences? How do you change the incidence when the stab is already glued into place and the wings are fixed?

Shims I assume?

I saw no need for any mods.

it is not a modification, it is a correction.

Not just myself. there have been more than a few guys with 62" Osiris ending up with up trim after building the plane following the manual.

mine came out with positive stab incidence of more than 1 degree which is not good at all.
So, I helped another member building the Osiris with 0.5 negative incidence relative to the wing. This is almost at 0 relative to the top of the fuselage with out canopy.

almost no elevator trim.

Stab tips are not in parallel also. so taping the elevator halves to the tip comes out with elevator halves not in parallel. I re-hinged both sides.
