Servo question time.

I've been reading through this forum and some say if using a gas engine (DLE 20cc) i MUST use digital servo's. Why is this?

Thanks to everyone for their responses, it has helped get me up to speed on GAS RC planes.
ryanbe15,
That is not true, digital servo's will give better centering and speed,if you're into 3D flying than you would want a digital servo,if you are into general sport flying/ light 3d flying a good anolog servo is fine like Hitec 625 or 645 servo's.
.
Due vibration of a gas engine it is recommended that you buy a servo either anolog or digital with metal gears, plastic drive gears orkarbonite gears will not last as long as metals gear,again metal gears are notabsolutely necessary ,but highly recommended and on my gas airplane I use only metal gears.

Thanks man. HS-645mg were actually what i was ordering.

For those that are using the DLE 20cc, are any of you cutting holes in the bottom of the rear fuse to allow for the hot air to leave the plane? I've read that this will help keep the engines cool.

Before you drop some coins on that servo, take a look at the XQpower 4020 servos from Redwing RC. You can get 5 for $40/piece ($47 for 1) and they will be no compromise servo for a 50cc airframe if you move up in the future. I am using them in a Pilot 30cc SBach 342 and they are a screaming deal for that price and the quality is top notch and the specs are just ridiculous for the price. Just make sure and use low impedance batteries. I use 2500ma/hr LifePo4 batteries with no regulator.

Specifications:
    [*]Gear Style: Futaba Arms[*]Modulation: Coreless Digital[*]Gear Type: Titanium[*]Weight: 2oz (59g)[*]Size: 40x20x39mm[*]Torque: 6v -300oz-in (21.8 kg-cm), 4.8v - 250 oz/in (18.5 kg/cm)[*]Speed: 6v - .13 sec, 4.8v - .15 sec[/list]..Joe L

Man that youtube video for them is pretty cool. I found the hs-645's for 26 a pop so still prob going to get them as currently i can't store/transport a large plane. But WOW those things looked sweet in that test.

For those who have used the DLE 20cc, have you had any problems with the firewall cracking?  Seems like cutting that much out of the firewall would weaken the structure.

I found these "DLE-20 stand-off" at www.seaplanesupply.com/aluminum.htm after I installed my Evo-26GT I do plan on getting a set for another project.If you re- read my build on page 4 and 5 you will under stand why I didn't use the DLE-20 on this airframe.Cheers: Rich

Cutting the firewall must not be that big of a deal if Aero-works is advertising it in their manual for adding the DLE 20cc

Yup, seen that on their 260/300 Extra manual's and if you read my build than you'll understand why I didn't cut my firewall,I have worked as an Aircraft mechanic for almost 30years I'm not going to do it, many others have with good results.

Hey Proteus,

Yeah man i read your explanation on page 4. Question, why didn't you use any offset for your engine?Looks like you mounted it straight center but inMuddin_Mavric's photos his engine is offset to the right (if looking at the plane from the front). [/b]

It's there, photo's are an opticalillusion,however it's smaller than called for on page 9 of the manual.The manual calls for 1 degree down thrust and 3 degree right thrust ,firewall to prop plate is 120mm or 4.75 your off set should be .2489" . Now on the Evo 26GT the engine has a much bigger "footprint" I wasl pushing the Greatplanes motor mount too its limits,the Evo 26GT is based on a MVVS 1.60size glow if you look at my photo's of the motor mount you will see the the mount has beenmodified at the base .250" of the engine sits inside the motor mount even after this my engine stuck out n addition .625"[5.125] further than the recommended distance. Also IMHO 3 degree is too much right thrust , so I sets my right thrust too 1 degree and 1 degree down my off set is only .089 if you want to read up on it check this website out airfieldmodels.com/information_source/math_and_science_of_model_aircraft/formulas/engine_offset.htm or if your lazy and don't feel like doing the math here's a nice toolwww.lcrcc.net/offset_calc.htmCheers: Rich

ryanbe15,
I just re-check my notes and the off-set and right thrust I gave is incorrect I add 1/2 of a degree so my firewall offset is .134" 1.5 degrees right thrust, if you look again on post # 97 after the motor mount tempplate[#2] it's there on photo's# 3,5 and 8 I should mention photo #6 is the bottom of the engine mount so may that and the temp plate threw you off,sorry for theconfusion.Cheers: Rich

For those that use a DLE 20cc, are you mounting the gas under the wing tube?  If so, what size tank are you using and how long can you fly?

My Edge 540 flew for the first time yesterday, even with the DLE 20 it was a little tail heavy. Next week will try again with batteries shifted foward for proper balance.........

I have just ordered the Phoenix Edge 540 from Tower and cant wait to start building
I will be using the DLE 20
Do I need a new engine mount or is the one supplied with kit ok
Some great information here which is great for us not so experienced builders.

I would like to know what suitable Futaba servo which is reasonably priced would be suitable
I have a Futaba 10c radio and would like to stick with Futaba

Also dont like CA hinges and would the Dubro pinned hinges be ok

I understand your preference, but do yourself a favor and check out the XQ 4013 servos at Redwing RC. They are only $34 bucks for 5 or more and the specs are fantastic - digital, coreless, titanium, 200.1oz-in, .11 sec. You'll be hard pressed to find those specs anywhere and the guys at Redwing give great support.

I started with just one of them on my 540 rudder and felt the difference immediately. I'm using 5 of them on my 30cc SBach since December with no issues.

God, I sound like a freaking commercial. But I'm not affilliated with Redwing in any way.

I used the CA hinges with the kit and had no problem. When I finally piled in the 540, I checked the hindges and they were all sound.

The XQ4013 are great servo's and have more power than Hitec 5645's lisen too Joe_L he gave you some sound advice.There is no extra balsa wood behind the hinges points,so intalling Dubro pin hinges isn't going to help that much,I would use the supplied CA hinges and pin the with stick pins form the wifey poo's sewing kit.
Imho the suppied motor mount is junk and I wouldn't use it,I would use a GP 60-120 size motor mount and trim the mount at the rear of the mount worked very on mt Revolver.Or you could buy the mount I mentioned on this page from Seaplansuppliese and buy some Hangar 9 standoff's for thier Taylorcraft, it's almost a perfect match for the DLE-20. When you prpgram your radio I would highly recommend you program your radio with 40% expo on low rates and 60-70% on high rates.My edge was overpowered with the EVO-26GT and very pitch sensive unit I increase my expo,in hindsight I should installed a DLE-20 in it.I sold the airframe and move on to a larger airframe got luck with you build.Oh almost forgot I would start with a CG that is slightly nose heavy,you will thank me later and you may want to move the forward slighly the plane is tail heavy.

You dudes overthink this ****. Don't listen to these "aircraft engineers" and their overbuilding bull****. You can cut the firewall to mount your gasser. You don't "have to use digital servos to do 3D", etc., etc. etc.. These guys like to build **** and cant fly. Build your plane the way you want to.

Haha! Looks like we have attracted a troll guys. Check his profile and you will see that he likes to stir the ****. Along with trying to legitimize his creds by being associated with a now non existent web site.

I have been flying rc for 15 years. Everything from helis to 42% IMAC planes. I stir the ++++ when I see bogus info from internet flyers. I just bought a Phoenix Edge that will have a RCGF 20cc mounted to it. I don't try to legitimize squat. I worked for DawghouseRC while he was still in business. As always, have nice day.

The supplied control horns are no good. They are not long enough to line up with the hinge line. Thus, very little throw. I only saw one guy on this entire thread mention that. Proves to me most of you don't know what you're doing when building.

"linkage supplied are too short to increase throws and control horns would not line up vertically to servo’s

Anyone still flying these? Tower had them for $174.99 with free shipping over the weekend, add in their regular discount codes and they can be had for $160 shipped. Too cheap to say no! Buddy of mine and myself just ordered up a couple of these for the DLE's.


I will be building mine with extreme detail to weight, if I can get it around 8lbs dry I would be very happy.
