If I get this plane, and I think that I want one, I will put the big Moki on it. I have the Moki 1.8 in a Sig 300XS and it's great. There is no glow mess like you's expect.

I just sold my BME 44 gasoline powered Patrick Extra and I know I will put the Moki in the next plane of this size. It is more appropriate power and there is none of the flying in the burble range between the high and low speed needles of single cylinder gas engines. I think the big two stroke glow engine is better in this application. The power/RPM's are very linear.

Well, my Edge had its first flight today and it was pretty hairy. I balanced mine at the location recommended by Dave Patrick and had to move two of my batteries way back in the tail and add just a bit of weight in the tail to balance out the Brison 2.4 and all of its gear in the front. After I took off, it became immediately apparent that the plane was very TAIL heavy. Go figure. Needless to say, I'm going to be removing my tail weight and possibly shifting my batteries a bit farther forward to move the CG a bit. The plane had PLENTY of power with the Brison 2.4 and required no aileron trim, a couple of clicks of rudder and just a bit of elevator which I will cancel out with the adjustable stabs. One thing of note is the VERY powerful elevators. I have my throws set at about 20% of max for my first flights which just about equates to Dave's recommendations, and it is VERY touchy even with quite a bit of expo dialed in. The rudder and ailerons were great, but the off-trim horizontal stab coupled with the tail heaviness made for some crazy approaches. The plane absolutely floats at an honest to god walking pace, but the plane either wanted to pitch straight down, or straight up. The elevators were VERY sensitive to being off center at low speed. Luckily, after a few approaches, the plane landed just fine, but I am definitely going to make some adjustments and try again tomorrow. The single servo per aileron and single pull-pull elevator servos worked GREAT and I'm glad I went with that setup and I think the Brison 2.4 is a GREAT choice for the airframe. A 3.2 is just not necessary due to the weight which on mine is just a shade over 14.5 lbs. Hopefully I'll have more success to report after making my changes. I'm also curious to hear any others who have had first flight experiences, so keep the posts coming!

Congrats on your maiden flight.

The wind was also a factor today in Columbia. I maidened two different planes at another field in the Columbia area today as well, and the wind added to the stress.

Look forward to seeing your additional flight reports after you get the CG moved. Tomorrow is supposed to be a better day, weather wise.

Rons plane at the field. It's in the ARF forum.

Congrads Ron, hope to fly mine on wensday. I will be using the ys dz & carbon gear and a few other wieght savers i.e light spinner, prop, battery etc . Shooting for 12 - 12.5 lbs. How many battery packs did you have in there and what did they wiegh? Also how much does the 2.4 with ignition & muff. wiegh? Just trying to deduce how close I can get on wieght.
Thanks!

I was just talking today about how I thought this plane would be a mean machine with a DZ in it. My Goldberg Sukhoi is an absolute beast with a YS140L, and I think the DZ would be great in the Edge with single aileron and elevator servos, Li-ion batts, and the carbon fiber goodies as well. Right now I have a 1400mAh NiCad in the nose along with the CH ignition module, a 700 mAh Nicad for the receiver power, a 6V regulator and Jomar Glitch Buster, and an 1800 mAh NiCad in the tail for the servos. I use 4 Futaba 9252 digitals and one Hitec mini for throttle. My total weight was right around 14.5 including the Brison 2.4 and muffler. I am using a straight down muffler on the inverted Brison and the weight with muffler and ignition (not counting battery) is around 3 lbs. I also have a bit of lead in the tail, but not much anymore after adjusting my CG. I think you could easily build one under 13 lbs with the YS as long as you used light batteries like a LiIon and you don't bother with dual aileron servos or tail mounted elevator servos. I can tell you that I had no flutter issues with mine and they only put out 110 oz in each.

Well, I made my second flight today and talk about a night and day difference. I haven't measured it exactly, but I have moved the CG forward fairly significantly and it is still just a bit tail heavy, but in a good way for aerobatics. I think I might move it forward a tad bit more, but not much. My problems with pitch instability on approach are gone, and the plane just floats down the runway until touchdown at a walking pace. It did have a bit of a nose up and ballooning tendancy when the power is cut, but I'll work that out in the balance. I had a bit of a frequency glitch problem during the flight, so I am changing over from my Airtronics FM setup to a Futaba PCM setup on the same channel to see if that fixes the glitches. I think with all of the metal pull-pull linkages, all of the batteries, and the CH ignition, there might just be a little to much RF noise for the FM receiver. Hopefully the switch to PCM cleans things up a bit. So basically for all of you building yours out there, don't be afraid to build it with a CG forward of what is recommended in the manual. It REALLY calms this plane down and I think it is going to turn out to be a real ***** cat once I get the bugs worked out.

Hi rongreg13
Do it take a lot of space in a house? I really want to get this DPM but I think it might be to big to store. Can you take a pic next to the plane? Thanks Bud

Take care

Now that you have some flying time on the DP Edge, I was wondering how it compares to other planes that you've flown? Or if you've ever flown the DP extra, a comparison with that plane would be great!

I was planning on getting the DP Extra & putting a ZDZ 40 in it, but after the DP Edge was released, I decided to wait and see how they compare. I was still thinking of using the ZDZ 40 in the Edge, if that is the way I end going. My 3rd choice was the H9 80" Cap . But after reading a few threads on that, it sounds like I'd have to move up to a 50 size engine, and I still haven't seen many flight reports on that plane.

Anyway, If you could share any info on how you rate the new DP Edge I'd appreciate it.

Thank You,

Mark

The plane is quite easy to store and transport. I have a complete set of wingbags from wingbags.com that include the tail covers. This really cuts down on the hangar rash. I store mine in the garage and it takes up no more space than my CG Sukhoi or DP Ultimate with the wings off.

The plane flies really nice. The control surfaces are HUGE for 3D type flying, so VERY little throw is needed for normal aerobatics. I use fairly high throws with a lot of expo so I can have the maneuverability when I need it at slow speeds. The is built super light and has an extremely low wing loading, so it floats and floats on landing. It flies like a much smaller and lighter plane when landing and you don't have to bring it in with any power at all to get a nice landing approach. The plane actually flies a lot like my CG Sukhoi which was also designed by Dave Patrick. The Edge can get tricky on low vis days mostly due to the center-mounted wing. If it weren't for the wheel pants, you could easily get disoriented with the plane on a cloudy day--but the pants help you to manage which side should be pointed up! The plane has very little stall break, kind of like a full size Piper Cherokee--it just mushes and starts to lose altitude. There's no wing drop or tip stall tendancies at all with the airframe. Rolls are very axial and you don't need too much expo on the ailerons. My Brison 2.4 is more than enough power and it will hover at just under 1/2 throttle and will easily accelerate out vertically at 3/4 throttle. The Brison has very little mid-throttle burble, so it is a real sweetheart of a combination. Once you work out the balance issues, it is a great plane to fly and easy to maintain.

Hi rongreg13
Do you think you can post a pic of the plane next to you? I just want to see how big it is next to a person. For the price is it worth getting? I want to use it as a gas plane. Thanks bud


Talk to you soon
DragonDavy

Sounds like a good idea DragonDavy...I'd like to see that, too! But don't forget to tell us how tall you are, so we can get a good comparison.

I'd still like to hear somebodies comparison of the DP Edge & the DP Extra, too. I like the way both of them look. So I'm basing my purchase on the one that flys best!

Thanks,

Mark

If you guys like it with a 2.4, then it should be outrageous with a Moki 210! A Moki 180 would be good too, and only uses 1 oz. of fuel per minute.

Sounds good h82crash!

I actually would like to get a Moki 2.10 some day. But right now I'm looking to get into gas, and can't afford the 33% models. So I'm forced to look in the 25%-27% range right now.

...And if you look at the weight of a Moki 2.10, it really isn't much lighter than a ZDZ 40, and the ZDZ 40 has more power!

But thanks for the thought,

Mark

What prop are you spinning on that ZDZ? The Moki 2.1 will spin the 20x10 at 7500+ and the 20x8 at 8200 or so.

The ZDZ spins less prop, like a 19x8, at less RPM.

-Cheech

20 x 10 @ 7400 RPM

But RPM can vary with location, climate & even 2 of the same engines by the same manufacturer.

I don't own a ZDZ 40...yet. I'm just basing it on what I've seen & heard from others in this forum, and elsewhere on the Internet. I've seen videos of a DP Extra with a Moki 2.10, and with a ZDZ 40...the airplane took off from a hover with much more authority with the ZDZ 40 in it.

I'm always open to any new information that I can learn, and welcome the input whenever I can get it...but you can't argue against a video. But then again, depending on where the planes in the video were flying...that could have made a big difference in the performance as well.

I'm just saying that the Moki 2.10 & the ZDZ 40 are close enough in weight & power, that the savings in fuel costs makes the ZDZ a very good choice...especially if you WANT to get into gas. Which I do.

Thanks for the advice, though.

Mark

Hey deryckere

What video is the one you are talking about with the DP Extra? Where can I see it or get it? I place an order for the DPM EDGE 540T and they said they will have it in 6-weeks. I also want to use it as a gas plane. Thanks


Take Care

I hear you, deryckere. I've had the BME and a couple of other gas engines. The BME was on my Patrick Extra and the power was good. One of the things I really LIKE about the big MOKI's is the smoothness of the power vs the gas engine , particularly in the midrange. There is no burbling while the engine transitions from low speed needle to high speed needle. My BME 44 spent much of its time in this "burble range" while at maneuvering speed. A little higher RPM and the burble disappeared, but then the plane was often going a tiny bit too fast.

So I understand what you're saying about gas engines. However, I am now thinking that these big MOKI's have a performance advantage over the single cylinder gas engines . They work well on these 14 lb airplanes.

As far as economic advantage , here is how I see it. There is a $150 difference in purchase price between the ZDZ and the MOKI's. The operating cost of the glow is higher, but I can fly the MOKI powered plane for more than a hundred flights on glow fuel before I see any operating cost savings . At one hundred flights, my interest in the plane may be half over anyway.

-Mark-

No question the Moki's are the better running of the two! I'm not denying that. Their reputation is known throughout the industry for how smooth they operate & perform.

But the ZDZ does operate differently than the BME. As the BME 'Burble' is written about more than any other gas engine that I've read about. I'm not saying that the ZDZ is without fault. It no likely has a burble, too. But you can't lump all gas engines in with the problems associated with another brand of engine.

Also, the money savings you mention aren't that valid. Because when I 'get tired' of a model, I don't throw the motor out with it. The motor will be transfered to a different plane, and everything I've read suggests that gas engines last much longer than glow engines.

Lastly...I REALLY want a GAS engine!

So, it's not really a Gas vs Glow issue here...it's a guy wanting to get into GAS, and just trying to find the best plane to put it in...without braking the bank, of course.

Mark

Besides the sound of a thumping gasser gives me coldchills. I've been bench running my RCS 180 and get 8400 with a 18x8 and 8000 with a 20x6. With all the ignition I believe it weighs in close to 3.25lbs though. It has a slight burble in the mid range but it seems to change with the prop selection. But it still sounds great!

If you decide to take the step into gassers in the 25-27% range you might as well plan on spending $1200-1500 at least.

I have a BME44 in a 27% CA Extra 300L and I love the combo so far. I have only 6 flights on it but I can already tell this is going to be one fine flying machine. Add in the fact that it's only 13.5lbs, compaired to my DP Extra using same motor was 16.5lbs thats a huge difference and it shows.

If you don't mind building I'd say get a CA Extra but if your looking for an ARF you can't beat Dave Patricks Extra or the Great Planes one. They are going to be heavier than some others but a quick and inexpensive way to get a plane of this size. Drop in a ZDZ50, BME50 or a DA50 and have a blast.

If you guys are getting a large range where it blurbers try leaning out the low end about a 1/16 turn until you notice less blurbing.

WreckRman2

Thanks for the info!

I already got a computer radio & digital servos, so I only need the plane & engine.

...And I would LOVE to have one of those CA Extra 300L's. I've only heard good things about them. Only problem is they cost a little more, and secondly, it takes me months to build an ARF!

If I do decide on the DP Extra, or Edge, are you saying that the 40 wouldn't be enough, or are you just saying that the 50 would be better? Because I've heard from someone, who does everything you can ask of the Extra (with a Moki 2.10) tell me that a 50 would be to much for one of these planes.

My other choice was the new H9 80" Cap 232, and I was told that the 50 would be the best choice for this plane. But I still haven't seen much written about how that plane performs.

If I was going to get a 50 size engine, I think I would look at the DA 50 first...but if I start to run low on money, I'd have to give the nod to the ZDZ 50. I still like the ZDZ if I was going to get a 40 size, though.

Thanks again for the input,

Mark

I don't know specifically which video he was talking about, but there are videos of the DP Extra running a Moki engine on this site:

http://www.3dbatix.com/

Then get a gas engine! This is a hobby and you should enjoy it....so if you want gas then get gas. Don't let other people tell you what is right for you.
