Dear RC friends,

I just bought a Dave Patrick Edge 540 T(not 40%) and I would like to know of those that fly with this model which is the best choice of engine for 3D.

Regards All.[&o]

I am currently putting my second one together, the first one i had a YS 140 DZ in it and it was good a 3D, it would hover between 1/2 and 3/4 throttle, this engine kept the plane light which was nice, this time I am putting in a ZDZ 40, I won't maiden this plane for a couple of weeks yet, I am trying to keep the plane light but with a gas engine. Another flyer who had the extra with a 210 Moki didn't like that set up, engine just didn't seem to have the power, I don't know much about Moki's so just relaying his experience. Alot of people put 50cc gassers on this plane, I called DA about it and they stated to me on the phone that the DA 50 would be too much for this plane, The idea for 3D is to keep it light especially in wing loading for 3D. I am confident I will like the ZDZ 40, my friend had one on a great planes extra and it was a rocket, the GP extra was a little smaller than the DPM Edge so I think it will be the right combo for me. What ever way you chose to go, stay as light as possible with the power needed to do the job.

I also have one of this on order, but I am debating about going with glow or gas. For glow I am kind of settle on the OS 1.60 and looking at BME, ZDZ and Brisson for gas. I am more interested in precision aerobatics but also will like to keep weight to a minimum. Any inputs, experiences or anecdotes will be appreciated. I know Dave Patrick does not encourage going with gas.

best regards

Thank you guys,

I think that my choice will be an OS 160, following Dave´s orientation of to prevent gas engines. Also because this airplane will not be what I will use with more frequency, then the fuel problem does not worry me.
More over a good gasoline engine is an expensive bit and only would be valid in a bigger airplane.

Dave actually mentions the zdz 40 on his website under weights of the Edge, for IMAC type flying a gas might be better because of down line breaking with the bigger prop, for more of a 3D plane I would do glow like I had or the OS 160. I spoke with Dave at the AMA convention in Ontario and we talked about both engines, He strongly recommended me to use 2 servo's for the ailerons with the ZDZ, he also mentioned that he used a gas engine on one of the proto-types, I believe a FOX engine, he said that he liked it alot. Whatever you decide to do, you will have a nice flying plane, I just got my Somenzini 72" Yak and I will be putting my 140DZ on that, and today I just received my 87" TOC Yak that I will be putting a DA50 on. I have alot of ARF building to do, I have seen some DPM edges for sale here on RCU, one was new in the box if I remember right, you might check there to try to buy one, usually see one once a month or so.

Take Care

If you are thinking about glow for the Edge, you cannot go wrong with the big MOKI. I have the Moki 1.8 in mine and it has PLENTY of power. The 2.1 would be better but my great running 1.8 is what I had.

Correct me if im wrong.. i was looking a the same plane for a home for my YS-140L. and was researching on RCU it looked like noone could get under 14#. Is this correct? That is the only reason i havent bought one yet. Im sure it will 3d fine if i could get it closer to the 12 they say on their site.... So tell me .. If i run 1 servo on rudder, liPo battery etc is this anywhere close to obtainable?

I weight 13 lbs, 14 oz. and no extraordinary weight saving measures. I have a decent size five cell battery. Everything else is stock. One servo per aileron and I did a single pull-pull servo on both the elevator halves and on the rudder. The throttle servo is small.



I think you could EASY get one into the mid/low 13's. The engine is small for the plane. Maybe the Goldberg Sukhoi or the Quiqui YAK is more like it.

-Cheech

what do you mean too small for the 140? or did you mean motor too small?

Correct me if I've calculated incorrectly, but if Cheech's Edge at 13lbs 14oz is running the Moki 1.8 which lists at 41 ounces, It would seem that a YS 140 that lists at 33 ounces could put this plane at 13lbs 6oz pretty easily? Not sure if the weights listed on the websites include mufflers or not.... Interesting to note that DPM lists the Edge prototype with a Moki 1.8 at 13.73 lbs and that includes a 3 oz pilot! He says with a YS 140, and no pilot it weighed 12.58 lbs. Must have been a batch of light balsa....

I agree, I think the 140L would be a little small for this plane if you want to 3D, The QQ yak would be great, I just received mine and the quality looks great, When I had my previous DPM Edge my weight came in at 12.75 lbs. I had lithium batteries, one servo per aileron, pull-pull on rudder and elevator, carbon fiber landing gear, all stock hardware with the exception of a sullivan tail wheel. My current set-up with the ZDZ 40 is carbon fiber landing gear, spinner and wing tube; Luthium batteries; one servo per aileron (throttle management will be the key); pull-pull on rudder and elevator; I have changed to Hanger 9 4-40 titanium pro links hardware with ball joints and the a 4-40 sullivan clevis on the ailerons with the stock horns and JR 8411 servo's. I added a Foam Pilot for IMAC and to keep the weight down I purchased a DPM instrument panel then made a color copy from my home all in one printer with regular paper and glued it in, I did this for IMAC. Other than that, the rest is stock

yea thats a shame to i really like the looks of the plane but am not ready for the 40cc plunge and that is what im afraid that If i got one and put the 140 on it it will be marginal.. Oh well thanks for the input

Hey I thought you already bought one. Well the Moki 2.10 is what I put in mine. No doubt it will be plenty of power. I have a 14 pound CAP232 with a Moki 1.80 and it is a rocket. With a Moki 2.10 the 14.5 pound DPM Edge should have plenty of power.

no I was about 6 months ago utill i found out the weight.. My 140 will jerk a knot in a 10 lb plane.. I was figuring 11.5 to 12.5 would be to my liking with the motor but not 14..

actually im buying an obsession for the 140.was kind of hoping you guys would have said different. that you managed to get 12 lbs out of one. it was wishfull thinking i guess
the 140 was on my funtana but didnt like it.. at 10 lbs 2 oz it was to rocket like for my taste


oh and yes i considered QQs yak too.. beautiful if it flys like EFs i would love it (which im sure it does).. I have flown my friends EF yak

Oh i see where the mistake is my name looks alot like the thread starter.. maybee that is what you meant

hahahaha....yep you actually made logic of my mix up. Nice work. Pheew. I gotta read stuff better. :-)

took me a second but then i figured it out

Hi, with precision aerobatics and light wing loading in mind what engine will you choose?

ZDZ 40 or Brison 2.4?

PS. I dont want to cut the cowl on the sides....

dj air hi... I have a dpm edge.. and i can't find the c/f landing gear and wing tube do you know any store or company where I can find them thanks

I have my dpm edge with a bme 50 and believe me.... it's awsome....just need to put the battery just where the cannopy ends on floor and you dont need to add weight any where

I owned one of these planes with a Moki 2.10 on it from DPM. The Moki does make good power on it, but I ended up with a DA50 and that was so much better. With the Moki 2.10 it was a great flying plane for mild 3d. I ran so many different props on it and found the Air Wild NX 21X8 to pull the best after break in. The plane would hover a small amount under 3/4 throttle. After putting the DA on it it was much more like my 100cc extra. A BEAST! I thought about the ZDZ 40 but for the small weight difference and the larger number of 50cc planes to move to after the DPM I got the DA! No matter what you run this plane is awesome! I hope you enjoy it!

I have a Moki 2.10 on mine. It could use more pull out power but I can do anything 3D on this ARF. It's an awesome flyer.

What RPM's are you getting with the Airwild 21x8? I have this prop and compared to the BAmbula 20x8 it is HUGE. It looks like way too much prop for the Moki 2.10 so I never even tried it. I did use it to run my DA50 on the bench, didn't run it long and never at WOT, just wanted to make sure the engine started and ran well. It sure did. The DA50 is not for the DPM though, it's for my BME 85 inch Edge.

I have a problem with my moki 210, (the DPM version) it keeps overheating. any one know who to send it to? My edge is becoming a hangar queen because of this pos engine.

I was getting 7550 with the NX prop with 5% coolpower. I also checked my props and it was actually a 20X8 NX. I agree the DA50 is much better off in a larger airframe, but I was never real satisfied with the DPM MOKI. Either way I no longer have the plane or either engine. 100cc was calling my name so had to sell just about everything else to get in the air.

I know you've been struggling for a long time with that engine so I won't go into all the questions like how much fuel through it and is there enough cowling exit area, prop size etc. I would send it to DPM. My Moki 2.10 has never overheated and I flew it in 90+ degree weather (harriers, hovering). Try DPM first.

BTW, I didn't have much luck with VP30 w/bypass loop and the tank on the CG in vertical uplines. The thing would flame out everytime. You may be leaning out the engine with that setup. I went to a Cline regulator and my engine never flames out, it runs great. I have my tank right on the CG. Turning a Bambula 20x8 at about 7100 RPM's.
