I assume both wings and the stab should be zero incidence... does anyone know for sure?

Lumpy n bumpy

I would think that reducing your throws would 'compress' the expo curve into a much smaller range and give it that 'touchy' feeling. If your linkages and servo geometry is correct, you should increase your throws to the recommended amounts as a minimum. On such an easy flying plane, with throws above the recommended low rates, it's docile to fly. Also curious if your only finding it 'twitchy' on the elevator or all surfaces?

reyn3545

From what little time I spent flying it, I remember the elevator most. Like I mentioned, I need to get out and make several rounds with it to determine exactly where the problem is. Today, after I got a little altitude on takeoff, all I wanted to do was circle around and try to land it. It was a little breezy today, but that wasn't what I was feeling. It's got to be something... I'll keep working on it until I either find it or crash it.

Hi guys

Bought myself a 50cc Ultimate for Xmas. I've been a good boy all yearHaven't started the build yet still waiting on the engine (DA60) and a few other things. Went with Hitec 7985 on ail. and elev. and a 7955 on rudder. Haven't bought a power system yet but I'm leaning towards 2 1100ma A123's through seperate switches to the receiver. Not sure yet on ignition. Lots of good info here

reyn3545

I could just send you my plane! Same setup. DA60, 7985 on everuthng but the rudder, 7955 there. I was going to use A123's, but everyone was out of stock, so I wound up using 1350 mah Lipo's.

The only thing I'll probably change is the Lipo's.... and you might think about it too. Not for the chemistry, but I'm probably going to move up to the 2400 mah size, at least on the receiver. The smaller size would be fine for most days at the field, but if I flew more than 5 or 6 times, I'd need to recharge. It wouldn't be so bad with 123's and the quick recharge times, but with Lipo's, that puts me down for a couple of hours. I've got some 4800 mah packs that I need to break down to 2400's anyway, so this will be a good excuse to go ahead and do it.

Oh.. for your ignition, you cal fly all weekend on a 1100 mah pack.

Good luck with your build. These Quick Build planes are great. You just open the box, shake all the parts out on the table, and before you know it, you're ready to fly!

reyn3545

OK, I put a new lipo battery (more mah), and a Fromeco regulator in the plane, also installed an external jack going to the data/bind port so I can use the data logger, and I moved that one antenna from the bottom side of the motor box.

It's supposed to be decent weather again on Sunday, so maybe I can get out to the field again, do some serious radio checking, and if all looks good, cross my fingers and take off again. I know this is a nice flying plane, I just need to find my problem before my luck runs out!

jcrider

I'll be interested to see what you figure out. By the way, how's that 60 running for ya

reyn3545

I wish I could tell you! It seems to run fine, but it airtime has been limited to 2 short circles. I've been fighting control issues too much to even notice that the motor was running.

reyn3545

Okay... a little windy to go to the field today, so I'll test a few things in the house....

Took the spinner/prop/cowl off to check the incidence. With the motor box sitting flat and level, the motor shaft checks out just fine... right thrust is designed into the motor box, the shaft is vertically perfectly level to the motor box.

I checked both wings and elevators... using the motor box as the standard, the wings are perfectly level, zero incidence on both wings. That checks out in the center of the top wing, at the root of the bottom wing, and at the cabane attachments of both wings. Stab/Elevator also checks out with zero incidence and perfectly square to the airframe.

Top and bottom wings are square to the fuse, equal distance from wing tips to the stab on both sides, both wings.

Great Job, Aeorworks!
You never quite know what you get when you buy a used airframe, but in this case, it's as square as anything I've ever owned.

So, now I know the problem isn't the airframe. Continue to focus on the electronics.

I have been flying the red, black and yellow for almost two years. The plane is perfect, the engine is the problem. The Evolution 58cc has lots of power and the 24x10 prop(CF) works great with this engine. It started out with a defective ignition that caused dead sticks at random. Next, the crankshaft bearings and seal had to be replaced. Also, the muffler was not aligned and it leaked. Horizon replaced the ignition and repaired the engine. The muffler company replaced the muffler. After all these problems, the only damage to the plane was the wheel pants. When the engine runs like it is suppose to, the plane is the best flying of my four 50cc gas planes. I am thinking about buying the DA60 to replace the Evolution 58. Does anyone have any comments about the DA60?
Thanks,
George Royal

reyn3545

I have the 60, and mounted on this plane. It's a drop-in replacement for the DA50, but there are a couple of differences once you get it mounted.....


When the motor is mounted inverted (standard), the carb needles are pointing straight up. So, if you want the ability to adjust the motor with the cowl mounted, you'll have to drill a hole in the top of your cowl. It's just a visual thing, lots of people like to have graphics or other things on the top of the cowl. I installed a 3/4 inch fuel dot in the hole, and had to trim some of it off with a dremel to keep it from hitting the motor mounting blocks. It looks fine, but it was a little unexpected.

You also need to install a choke servo. You could probably snake a piece of nyrod or something through the back housing of the motor, but it really works a lot better with a choke servo.

The motor itself has only been off the ground for a couple of quick flights (read above), but it did seem to run fine. Lots of people have posted positive comments about the motor over on FG, but no one's had a good chance to fly it for any extended time. They just started shipping around Thanksgiving.

Thanks Mike,
That is very helpful info. I checked DA's website and they still don't have the DA60 listed. I did see an ad in one of the airplane magazines.
I hope the DA60 turns out to be a great engine. I have a couple of DA50 engines that are a little over two years old. They both have been flawless, but one does run better than the other.

reyn3545

No problem... I called DA around the first of November, when I heared they were taking pre-orders, and got on the "list". I'm not sure if they still have inventory,or what their plan is to stock up other resellers. You might call DA and see if they have any or when the expect the next batch. Good luck. You can't go wrong with one of their engines.

I'm getting a new car (HHR) to fit more planes and I could use some advice on engine selection for the U 20-300. I want good smoke and vertical performance and good sound.
is the Saito 57cc Gas Twin Engine 4-Stroke a good fit?. I'd like to see the rockers sticking out on the sides....
thanks,
Philip

reyn3545

I'm not that familiar with the 57cc gas models... I do have a couple of FG-14b's on a Beech Baron project. The main thing you want to consider is the weight... this plane is pretty well balanced around a DA-50. If the Saito is in that same weight range, you should be in good shape. If not, you may need to shift things backward or add tail weight.

Also, the 4-stroke gas motors don't produce the same high end power that 2-stroke motors are capable of. They run much smoother, offer better now end torque, but will have less top-end speed than a 2-stroke of the same displacement.

I had one of The Saito 450 3-cylinder glow motors in the past... a real horse of a motor, but it wouldn't fit on anything in the market today. I wound up overpowering an old Waco with it.... great to hear it go by, but you couldn't really work with it at full throttle... those old planes have way too much lift in the wing for a motor that big. That's the lesson that I had to learn in this game... find a plane you like, then get a motor that's designed for it, otherwise there will be compromises.

the planes are on back order[:@], but that gives me time to get all the other parts set. I am (at this time) going with the DA60 with smoke. I have a futaba system so do I go with 6v or 7.4V servoes?

reyn3545

OK.... it's alll back together and ready to go. With tank installed, CG at recommended location, it weighs in right at 19 pounds. A little heavier than it was originally, but I used heavier ply for the firewall, plenty of epoxy, and I'm using a 3-cell Lipo with a regulator... all adding a little weight each. There's plenty of motor for the weight, so we'll see how it goes this weekend.

I think I got one of the last three they had. And with Futaba also, I am running a Hobbico LiFe 3600 for receiver and a spare Spektrum 1100mah ignition pack.

I just got my spinner from Valley View(gorgeous btw(thanks Jody!!!) and thank god, it was literally a "drop on") and I need to check my CG again also after finally adding the ignition and spinner. Even though the spinner is lightened, of course it added some weight. The backplate was pretty substantially thick, so I am really curious where it will balance out now, as prior to the spinner, I was balancing right on the back cabane strut. Out comes the EZ balancer!!!! :-)

Mine came out extremely light. So light that I called AW to see if maybe my scale was off. But then, I turned around and measured my Edge, as I know the weight of that one, and it was spot on, so, I am thrilled and will be glad when the weather breaks so I can maiden it.

reyn3545

How light is extremely light?

Also, if I draw a line across the bottom side of the upper wing, 1 1/2 inches back from the leading edge, it falls about an inch in front of the rear cabane strut.... is yours balancing right on the support itself?

HelividD

My Feedback: (1)

15.5 lbs light with spinner and ignition.

And yes, it is balancing about an inch in front of the rear cabane strut now. Before that, I was balancing right in front of the strut, but those two items moved it forward that bit.

reyn3545

Wow.. what did you do to get it that light?

I really wasn't focused on the weight, used overkill on the servos, batteries, etc... but I don't think I have 4 extra pounds of overkill!

HelividD

My Feedback: (1)

Yeah, that was my response also when I weighed it for the first time. I didn't even think about saving weight going into the build whatsoever.

I simply used 3305 servos on my control surfaces, I am trying to remember, but I think a 3010 throttle servo, a Hobbico 3200mah(it is either 3200 or 3600, I can't remember) LiFe reciever pack, 1100mah 4 cell Spektrum ignition pack, the gas tank(no smoke tank used), and I am not using the Fromeco system with the 5200 pack that they sell, and no redundant system.

I still have my optical ignition, but I did a pretty simple setup. I completely destroyed my GP Ultimate and I ended up using the servo's from that. I said to myself since I had decked that Ultimate out with custom decals, etc, that even though the Aeroworks kit cost more and to me after building an AW edge, was a nicer kit, that I wasnt going to go nuts with it, as it could be rekitted at any time, verses helicopters that I fly that, rarely these days, can you rekit them. So, that was my thought going in from the beginning. I didn't want to use cheap components at all, but I wasn't going to go nuts, as I don't fly extremely hard "yet". I will upgrade servo's at that point.

Though, I did have to make little balsa spacers for the servo's so they would not rub the top film of the ailerons. But otherwise, I just built it according to the instructions. It really wasn't anything I did at all. I asked the person I spoke with and they indicated to me that the weight savings on the servo's, the power system they use, the smoke tank setup, etc, "can" save a lot of weight. He was saying that the Hitec's are metal cased, etc, so just those types of things.

But yeah, I was shocked too!

I just finished mine this weekend...blue, yellow, white version. I need to figure a way to weigh it. If mine is as light as yours, I'd feel totally elated. I expect it to be 18-19 pounds. Jon
