Status: offline 		Hello,

Well, I made it out to the field today to put the maiden flight on my new Black Magic. It really flies extremely well. I have never had a plane that flew this well right from the start. Here is what I have chosen to use in the new plane...

Plettenberg 30-10
Castle Creations 85HV controller
Tanic Packs- 5s2p batteries run in a 10s configuration. 4960 Mah
21x13wide APC prop

At full throttle, I am seeing the motor pulling 65 amps at around 2330 watts. I did not tach it, but it seemed very strong in the air and would pull straight out of sight. My motor temps were around 15-20 degrees above ambient which was in the 85-95 degree F range today. The packs were between 100-115 degrees F. The weight was a big concern for the builder (Mike Hester). But, the weight is 10 pounds, 10 ounces. For the size of this airplane, that is definitely an accomplishment.

I was able to make several flights going through the Masters pattern. Man, this thing really grooves and the electric set-up is very nice. I think I am going to like the !QUOT!dark side!QUOT! as some of the local fliers call it. Hopefully, I'll get some pictures posted later this week. I have not had a chance to put all the graphics and decals on it yet. It looks like I am using around 3500-3700 mah to get through the Masters pattern and still having some time to play around after. Have I mentioned this thing flew well???

I have to admit, I was skeptical. I was really concerned about making weight when Emory told me which packs and motor he was using. most people said it would be all but impossible, especially for a wood plane. But those packs are slightly over 3 lbs, and it came out 10-10; with TP pro lites it would have been about 10-4 or so.

But I wouldn't touch it. It's almost 12 hours after it first flew, and my jaw is still hanging open. Mine (with OS 140s) flies way awesome too, but this thing.........my god, I'm just speechless. it may have been fair amount of work, but it was worth it to see the looks on everyone's faces.....and that includes Top Gun flyers (and winners).....when this thing flew with Emory at the sticks. By the 4th flight he looked like he'd been flying it for years.

I'll leave it be and let Emory go into detail, but I don't know if it was the plane, the pilot, the weather, the electric set up or a really matched combination of everything, but that was way cool to watch.

Now take care of it!!!! LOL And I'll see ya in the morning.

-Mike

Congrats on the maiden. Been looking forward to seeing how the electrified Black Magic turned out. WELCOME TO THE DARK SIDE... you'll never go back my friend!

The weight looks good too... 10 10 will probably be just about right... with a big fuse like the Black Magic has, or at least appears to have, you don't want to be too light... will get bounced around too much. If you used the lighter packs you might end up ballasting the plane up in windy conditions.

Anyway, congrats and let's see some pics!

Compliments to the designer, that plane just 'looks right'.

Tom

Sounds great Emory! Welcome to the club You will never go back

Give a 21x14 a try on that motor as well, about the same load as the 13W, but I feel it has similar if not more power and a better constant speed about it.

I will give the 21x14 a try in the near future. For now with a new airplane and a contest in a few days, I'm not touching it

I will get some pictures posted before this coming weekend, since I plan to have all the graphics finished by the Ocala contest.

Emory.

Status: offline 		Well, sadly, my plane met a premature end this past weekend. After only 18 flights, it bit the dust due to some sort of radio interference or failure. I lost count, but I think I am either in the 3rd or 4th stage of grieving at this point. I should have some good pictures to post soon. A few guys took some down at Ocala.

Anyway, the only good news is that I have another one. But, I hate to see the first one go so soon.

Emory.

My condolences on your loss. I have lost two already this year to REALLY bad luck and do know how you feel. There is bad air all over this year, sorry you were a victim as well.

Tom

RIP, E-1. I think I'm on about the second stage myself......

Thank you for letting me fly your V2-e at Ocala. I just wish we found the cause of the problem before Sunday morning. I know it's hard, but V2-e2 is waiting to get in the air You've still got my program, so give it a try and carry a bit more power and you'll be grovin again.

Jason

I'd be real bummed if I didn't have another one to fall back on. I'm going to get all the electronics sent in this week (RX, TX, servos, etc...). I hope they will find a reason for the crash, but I know that I may never find out what happened. Anyway, I'll soon get the other one in the air.

Emory

Wondering if you got BM V2E #2 airborne? Sure would like to see some photos, if so. Was also curious what you would run this time for power. I bought a kit from Mike and was going to go 2C glow, but a friend went electric in his Brio and that got me thinking about electric if I can make the the whole project make sense from a building and cost perspective.
