Status: offline 		I received my 77 inch CG and I was pleased with what I saw. This is a great looking ARF and has lots of quality touches. My only criticism would have to be the over sized engine box and the rudder. What's with that thing? It's not even close to scale looks. I bet it's highly effective but definitely not IMAC legal. Also the canopy seems long, not quite the T version of the Edge but still longish.
I will be using a DL 50 once the engine has at least 4 gallons. It's currently on my Extra 300.

Do you think one Futaba s3010(No MG, no digital, but 90oz torque @ 6V) is enough for one aileron ?
I only planning to do sport flying.
Thanks for replying.

NO I do not think so.

I would not go too weak (I mean the gear set) on a one servo wing.

Even if you wollow into the sky on a 120 glow, put the nose down from altitude and you have speed.

That is just my opinion.

Status: offline 		I have been flying my Edge for a few days and I really like it. It's very predictable and really slows down to absurd low speeds when it's time to land. I have powered it with a DL50 and it's really grossly overpowered. I can hover with just 3 or 4 clicks of throttle. I have used just one servo per wing and it's worked fine like that. I had to work a bit on wing/stabs incidence as inverted was a bit rough.
Setup:
5 Hitec 645 MG
1 Hitec 475 Throttle
DL 50
22X8 JXF
Align lipo regulator
1800 2s lipo for radio
r7000 Spektrum
1100 Nicad 4.8 for ignition

The plane has great looks and will make any pilot very proud!

Status: offline 		No, I wouldn't use that servo. I would use at least the JR Sport ST126MG for that plane.

Like I said before here, Goldberg set those planes up for 2 servos per wing, and you can get away with one, if you use a more high torque, metal gear servo. I used them on my 77" Extra 330, and they work fine. Just make sure to go with the 6 volt battery pack, so you'll get the most strength out of the servo.

This plane of yours may be a little pricey, but DON'T risk losing it all becase of weak, nylon geared servos.

Hope this helped. K-Dawg

Status: offline 		KDawg,

The Hitec 645 MG is a powerful servo with almost 10 kgs of torque. It has metal gears and double ball bearings. I'm using this servo on all surfaces and the 475 on throttle. As I'm using a regulated lipo, I bumped voltage to 6V giving me full power to the servos. The JR servo you mentioned is basically in the same class. Thanks for the advice.

Got the same servos in my 77.5" Edge 540 allso on all surfaces on 4.8V and the work 100%. On two I have a bit of a centering problem. Not bad in the air though. But they are strong!

Status: offline 		Thanks doublesixes, and Karldascher.

You're right. The Hitec 645s are also a good choice.

I should have made clear that my advice was to jrotor, who asked about using the Futaba 3010s nylon gear, with 90oz/in torque at 6 volts. Those I would not use. The 645s, as well as the JR ST126MGs are a good chioce. I think the JR sports may be a little faser, but either one is a good choice for sporting, and not too radical aerobatics.

When I started in this hobby, I began with a JR radio system. I stayed with the JR products for a while, and have began experimenting with other servos, and recievers. I came to find that the Hitec servos, and recievers are of good quality, and work very well with my JR transmitters. They seem to be less glitchy than the JR recievers that I've used (really, almost glitch free), and will accept any servos you want to use.

I've recently started a 50cc project, and I'm using all Hitec servos, except for the rudder. I researched, and found out that the Hobbico CS-170, ($89.99) is the same servo as the Hitec HS5955TG, ($114.99). Which one would you use?

There is nothing wrong with the Futaba products that I'm aware of. I just started with the JR, and some of the Hitec products are universal use, so I've mixed them up a little, and have had good results

I hope this helps, and clarified my last post.

Fly safe. Ken

So Tell me how the DL-50 is working out? I've got a Dietrich 50cc Extra 260 I'm building up, and I'm going to use a Brison 3.2 on it, but I'd like to find out how some of the guys are doing with the DL-50, in case I do another 50cc, or if the Brison doesn't work out.

Regarding the engine overpowering the plane, maybe the Brillelli 46GT might be a good choice for transplant. I've read about them, and for this size plane, they seem to have enough power, without overpowering.

Check out these vids. One is the Extra 330, the other is the Yak 54. Both are the Goldberg 77" models, and do well with the Brillelli.

Status: offline 		Ken,

I think the DL-50 is a good engine and very powerful. The 77" Edge is a bit small for that kind of output although its weight is on par with what CG recommends for a gasser configuration which is a Fuji 40 or something of the like. My DL-50 required some messing with the needles and isn't still running like it should. It's getting better with every flight though and the amount of available power on an airframe like my Edge (about 11 lbs) makes it very easy to operate. Sometimes lots of power is insurance for risky maneuvers.
KE is a lot of work as it's got coupling, not a whole lot but still noticeable. Inverted harriers require a very soft touch since the plane want to climb with just a hint of throttle. Rolling harriers are a breeze. Regular harriers are very easy showing virtually no wing rocking in high alpha situations. Hovers could be done for a long time if the plane is properly balanced. The plane tracks well but it's pitch sensitive and will shift up and down as it encounters different air densities. This is not a plane that shines in IMAC, but better suited for 3D, especially with a powerhouse like the DL-50.
Once the pilot gets really acquainted with this airframe, the fun begins. It can fly really slow and if you are into that kind of flying, you'll find the Edge/DL50 combo, very rewarding. I'm pretty sure there are far better choices for a 50cc frame like WH, Aeroworks, Dietrich, EF, QQ and others but I'm not really disappointed with my purchase.

Hi K-Dawg

Wish I could get my hands on that Diethrich 50cc plane. I like the looks allot and the way it is built (from pics I have seen on the net) I have never seen one in South Africa. Could maybe get one here but the shipment will proberly be as much as the kit. Let us know when it flies!

Cheers
Karl.

PS I have actually gone and crashed my plane a few days ago - total wrigh off. Did a low low knife edge and it managed to snap it full throttle into the dirt as it trached towards the crowd (at airshow)
