Status: offline 		I know there are not many of the new Matt designed Beryll out there yet, but was wondering if there are any flight reports?

Thanks

Status: offline 		I was fortunate enough to get a Beryll and I am putting it together now. I hope to have a first flight within a month or so. I will post a flight report then. The "kit" is beautiful, usual Oxai high quality.

What is your anticipated power setup? We would love to see some pictures.

Status: offline 		Mike - I will be running the Hacker C50 14XL Competition motor with the 6.7:1 gearbox and the 90A speed control. My plan is to use the TP5300 10S4P batteries. I am currently flying an electric Angels Shadow with the same basic setup (it has the regular Hacker C50 14XL) and it works great. All of the power that you could ever want and, so far, great reliability. I basically went to school on Tony Frackowiak and Jerry Budd out here and copied their equipment setup (Thanks guys!) I am a firm believer in "imitation being the sincerest form of flattery"

I will try and post some pictures later this week.

Thanks

Jon Carter

Status: offline 		I did the first flight on the Beryll on Sunday. It was great! I still don't have any pictures but Scott Covey took some video and it's on the NSRCA D7 website (http://www.nsrca.org/d7/) I set up the control throws the same as my electric Angels Shadow and they are all about right. I set the wing at 0 and the stab at 1/2. The plane took about 6 "beeps" of up elevator trim and about two "beeps" of right aileron. (I have my trims pretty de-sensitized so that's not very much control surface movement) I put 4 fairly easy flights on it gradually building up to snaps and spins on the last flight and everything went very well. It has a touch of pull to the belly on knife but just a touch. The up and down lines were very straight. (Except for my wobbles!) It's a beautiful plane and it seems to fly as good as it looks. I think the Matt's have another winner here!

Status: offline 		Jon;

I've watched the video twice, I like the way the plane presents. Now the questions begin

Do you have an all up weight yet?

Two elevator servos in the stab or single with DEPS or other similar system?

Where did the CG end up?

Did you really mean that the stab was 1/2 positive to the wing or vice versa?

Thanks

Mike

Status: offline 		Mike - The plane really does present well! It's got a really nice constant speed "look" to it.

The real (no kidding) all up weight is 10lbs 15oz. I'm 1 oz under the limit. I didn't really go out of my way to be truly fanatical about weight reduction. At the same time I tried not to add any extra weight either. My Angels Shadow-e is 10 lbs 8oz. That said, the Beryll flies very "light" to my feeling.

I am running two Futaba 9650 mini digitals in the stab. I am also running the 9650's for the ailerons.

Per an e-mail from Wolfgang Matt I set the C/G at 175mm from the wing leading edge.

My starting point for incidence was putting the stab incidence 1/2 degree negative to the wing. (I am not usually super careful with this because I always find myself adjusting wing and sometimes stab incidence based on flight performance)

I will post more as I trim it out.

Thanks

Jon Carter

Status: offline 		What a beautiful website! Thanks for sharing that video with us. Hope all the test flights go well. Someday, I'll be going electric! I just have too much invested in my brand new Angel's Shadow/YS at the present time.

Status: offline 		The website is really great. Scott Covey is our webmaster and he has really "pumped" up the site. He uses a wireless hookup and actually puts preliminary contest scores up as the contest is going!

The Angels Shadow is a great plane also. That's what I've been competing with for the past 4 years. I currently have about 85 flights on my electric Angels Shadow and I really like it. It will be a tough choice as I get more familiar with the Beryll of which plane to fly!

Thanks

Jon Carter

Have about 20 flights on my Beryll. Do you also find that there was to much right thrust at the start? Had to reduce by a bit.

Status: offline 		Hi

The Beryll is an absolute beautiful plane with exceptional paint quality. After flying an Impact it is a great improvement, but obviously very costly. Can buy two Impacts for the price of one Beryll, and I got mine directly from OXAI. The nice thing is that every set up is done by OXAI and can be trusted. Took two days from work and plane was ready to fly. The only aspect that I had to change to date is to reduce the right thrust. At half throttle it is ok but anything more and it pulls quite a lot to the right. I am almost there. Tucks a little to the belly on knife edge, about 5% up elevator mixing on JR 10X. Rolls are axial and snaps are great. Flying Hacker Comp 14 XL with APC 21X13 E wide blade and TP 5300 batteries. And this is the greatest, all up weight 4,802 KG. I used some of this available weight by building a removable battery tray untill all the CG set up was complete and prop selection finalized. The batteries do not go on the intended place on the front tray and had to be moved back to get correct cg.

Will post some stats and pictures.

We are getting ready to finish off our Beryll. Pics and stats of your final setup would be fantastic.

Thanks

Status: offline 		I have not noticed a need to change the right thrust. I also have a mix in to fix the tuck to the belly on knife edge (~ 5% also) I have ~ 70 flights now and I am really liking the way the Beryll flys. I have moved the CG back a bit from the starting point (175mm back from the leading edge) I am at about 185mm now.

The Beryll flys so great that I might have to try and get another one!
