    Status: offline     		The tail gear uses a nylon bushing to swing the wire on and a metal bracket and wheel collar to hold it in place. The key here is to align the metal bracket properly before drilling the holes to secure it. The assembly is light yet sturdy. I used medium CA to glue the nylon anchor and post.

    Status: offline     		The horizontal stabilizer is glued in place first along with inserting the elevator joiner rod at this time. The covering is removed from both top and bottom sides of the stabilizer after marking it along the fuselage once properly aligned.

    The elevator installation is a combination of epoxy on the joiner rod and thin CA on the hinges. The hinges have been updated from the manual description to 3 larger pre-cut pieces of hinge material for each half.

    I had no problem with the installation and the alignment was perfect.

    Status: offline     		The RimFire motor comes with the x-mount already installed so you only need to attach the prop adapter using the supplied screws. The Edge 540T is designed for the RimFire 42-50-800 outrunner motor so it simply screws onto the motor box using 4 screws supplied in the kit.

    Instead of using the supplied hook and loop material to mount the ESC, I used two tie-wraps.

    Also, what size is the spinner? I'd like to bling things up and go with an aluminum spinner and a Xoar prop. I really like the way Xoar props fly on my Bipe so it's definately worth a go on the 540. One last question... I'm thinking of going with HS82MG's all around. Anyone see any reason not too and will they fit without carving things out too much?

    Thanks fellas,
    Jesse


    This E-Flite Aluminum Spinner will fit perfectly. I have one and sized it to the plastic one that comes with the ARF and it's spot on. One thing you'll want to do is make sure you ream out your prop to the point where it will seat slightly loosely onto the hub of the adapter. I went one reamer-size too small and stripped the aluminum threads trying to tighten it down.

    I also test-fit the HS-81 and HS-85's in the servo slots on the wing and they fit perfectly snug. I believe the HS-82's are the same dimensions. Looks like you are good to go!

    Status: offline     		My Futaba S3150 Slim Digital Servos arrived so I will use them on the rudder and elevator. The extra torque and precision of the S3150 servos comes with an extra price. Since they are not rated for 6v either, I will likely program my CC BEC for 5.5v to half the difference between 5v and 6v operation.

    I used the outside hole on the longer servo arm and second hole from the base of the nylon control horn as recommended in the manual to achieve a +- 45 degree swing in the elevator.

    Status: offline     		Nice job so far on the build. I just picked mine up yesterday and can't wait to finish my build I am on now and get started with this very nice looking plane.

    I do have a question for the ones who completed the build. Did you use the Pull Pull on the Rudder? I noticed that Greg did not, I was wondering what would be the reason for using the servo in the Tail or Pull Pull.

    After reading this thread I have not really seen any negative reports or has anyone mentioned of they noticed any bad habits. I have built and flown many of the Great Planes Models; most have been done really nice and flew even better.

    Can't wait to see more video and read more while I assemble this kit.

    I went with the recommended setup for motor, ESC and servos.

    Status: offline     		Looks like Greg's got the servo in for the elevator but no mention as to whether or not he's going pull/pull on the rudder. I intend to just because I've never done it, but it seems to me that pull/pull could only mean more precise control of the surface. I'm kinda leary of the string they provide for it but I have wire left over from antoher build that I intend to use.

    Status: offline     		Wingwrecker, thanks I too was thinking of the pull pull, after reading the manual it says it’s the recommended way to go. I guess If I was using a heavier motor, or heavier battery, then the tail would be the place for the servo.

    Your answer seems to make me want to try this. I didn’t know you would get a more precise control.

    My plane is to wait and decide this when I install everything, then I will check the balance. One reason is I could sue this as a good sport flyer. I would place 2 batteries in parallel and get twice the flight time, well almost twice, weight does effect the flight time. Anyway I too have a leftover pull pull (wire) I will keep searching for other answers.

    One thing. I was inspecting my Kit and everything is good except I notice 2 things.

    1. The Tail/rudder is damaged, the very tip must have been hit against the box. It is minor damage, but still damage. I will try and glue this, if it does not come out straight I will be contacting GP.

    2. My Canopy seems funny when installed. As you know it comes installed on the fuse. But I noticed mine isn’t seating very well. Maybe because the tail had been damaged (Maybe the box got dropped real good) but the Canopy seems like it sits back toward the tail to much. The reason I say this is because there is a slight gap between the canopy and front. Its a small gap, but noticeable.

    Other than that, the kit looks real good.

    Status: offline     		Hi guys,

    I trust all you North Americans had a nice Thanksgiving holiday! I was forced to clean up my backroom for company and promised not to work on planes for a whole day.

    The pull-pull rudder assembly is used when the design cannot tolerate additional weight in the tail (for proper balancing) and for precise aerobatic control. Other designs put the rudder servo in the tail with a short strong control linkage. Both ways work great so I am using the pull-pull installation because the Edge 540T will balance perfectly using the recommended RimFire motor.

    The only change I made from the manual instructions was to eliminate those tiny metal crimps. Since the pull-pull "cable" is really reinforced string, the crimps are not needed as you can more easily tie a knot in the string and secure it with a small dab of CA.

    On the inside fuselage photo, you can see where I installed the first crimp before I decided it was too much work. After the lines are all connected and tightened, unscrew the nut and add some thread locker to the rigging coupler threads and tighten the nut back up.

    I will be using 3S to fly mine. I am looking for the Sport more than the 3D. I use my Reactor Bipe for 3D. By the way, a bigger Reactor Bipe would be a nice plane

    Status: offline     		I've a question regarding servos. I have recently acquired 4 Hitecs to use in this plane; two HS-85MG's, one HS-81MG and one HS-81 plastic. The 85's are going in my wings, but where should I put the 81MG? Being new to 3D I have no idea which of the two surfaces will encounter more stress/abuse. My brain tells me to put the MG in the elevator just because if the rudder strips in flight it's not so cruciall for landing. Though, I don't think I've ever had a servo strip in flight...

    Any thoughts?

    Status: offline     		I am curios about the comments on this GP Edge 540T looking more like an Extra. Other Forums/People have made this comment.

    Greg any comments?

    The only servos I have ever stripped are for the rudder. It has only happened with cross winds and I didn’t correct in time or landing to hard on the tail. But those were Hitech 55's. They are my choice for most of my smaller planes.

    I say good choice on the wings, and maybe a good choice would be for the elevator also, after all like you said, loose the rudder no problem, loose your elevator, its that time you will wish for a miracle.

    Status: offline     		I'm so jealous of you building your plane. I made a promise I would not start this build until I repair my E-Flite Mini Edge 540 first. I lost power on take off, Bad Deans, I even checked everything, ran it around on the ground like a RC Car, held it while WOT. Guess it wasn’t enough. Anyway, I have applied my first coat of 30 minute Epoxy and should be done with repairs this weekend. Then it time to the build of this very nice looking plane.

    I can't wait for that time when I get to fly her.

    Status: offline     		There isn't sufficient difference between your Hitec servos to make a noticeable difference. The HS-85MG weighs similar to my Futaba S3150 digital servo so using that for the elevator will be fine for balance. Since the model has a set of "Experimental" decals, it can be called whatever they like. The wings are pure Edge.

    Shown here is the general locations for my components. I added the CC BEC which required soldering the leads to the Dean's connector on the ESC. I programed my voltage for 5.5v using the CastleLINK USB Interface Adapter. I also needed to move the ESC aft so that it was easier to plug into the battery.

    The pack position in the photo gives me a balance around 77mm which is about as far back as they recommend. By moving the pack forward about an inch (2" forward was available), my Edge 540T balances at the recommended 71mm. Keep in mind that where you like your CG, within reasonable limits, is a personal preference. For 3D flying, we generally keep it further aft and have all the control surfaces swing about 45 degrees (minimum) in either direction.

    The spinner backplate and APC 12x6 e-prop were drilled out with a 5/16" bit to fit on the motor shaft. I had no installation issues although the backplate ended up quite close to the cowl. I used the recommendation in the manual for taping the cowl you if plan on "performing violent maneuvers". Initial motor testing showed no excessive vibration.

    Status: offline     		Greg, have you taken any meter readings with the motor and prop yet? I ask because I noticed after picking up the 42-50-800 today that the package insert shows a reccomended 60a ESC for this motor on 4s with a 12x6, showing a tested 50.2a @ 743w. Yet the plane literature reccomends the 45a esc on the same configuration (with a BEC.)

    I'll be double-checking my meter readings thoroughly. I'll be testing with a suppo 40a and castle 10a BEC. Until then, what kind of amps/watts are you getting?

    Status: offline     		Those numbers don't look correct using typical LiPo cells for this application. My guess is that they may have used a bench supply where the voltage does not sag under load.

    The GPMM3141 Parallel ESC Adapter can be used to connect the CC BEC without soldering onto your ESC connector. Earlier in my review, I touted "No soldering required" when it really applies only to the 3s LiPo sport flying setup. For the 3D setup, you need a way to connect the CC BEC into the battery. I found it simple to solder the CC BEC wires onto the Dean's connector of the ESC. Don't forget to pull the red center wire from the ESC control line going to the throttle channel since the internal BEC of the ESC is not needed when using the CC BEC.

    My Edge 540T was Ready-To-Fly at 53.3oz (3.3lbs) including the 8.3oz 4s LiPo pack.

    I measured 376 watts at 29amps using the APC 12x6 e-prop which will provide 114w/lb. I thought this was a bit low for 3D flying but I will try it first since the thrust equals the weight at about half throttle. My guess is that they experimented with the sweet spot and choose this prop size.

    Since none of the components are being stressed, I will also try a 13x8 e-prop that is recommended for the 3s sport setup.
