    Things certainly seem much busier today than just several years ago.  Everything is getting faster providing more instant gratification.   It only seems natural that the world of radio control model airplanes would follow suit.    I know I am busy and the thought of building a kit from scratch is something I can not even comprehend.  Even the standard "ARF" (Almost ready to fly) models are not "ALMOST" enough for my taste.   Henceforth - the world of "RTF" (Ready to fly) models. 

    Parkflyers.com caught my eye with their new Edge 540T RTF airplane for several reasons, but most importantly it was Ready-to-Fly out of the box.   Let me clarify, RTF in this case as you will have a few minor assembly steps that require no glue or special tools.  In fact, they even give you the tools that you need in the box.  All you need is about 15 minutes and you are ready for the field.   It will take you more time to charge the battery then to have the model ready to fly.  

    Many things impressed me from the original ads I saw for this model.  I loved the look of it.  In Fact, I did not even realize that it was comprised of foam until I opened the box.   I loved the color scheme and graphics.   I liked the fact that it comes with a nice 4 channel transmitter, the battery, and charger, all in the box.    Both the ads and the information on their website all state that the Edge 540T will perform many aerobatic maneuvers as well as some 3D including hovering, and other stalled flight maneuvers.  

    Now that I have it here in front of me, lets open the box and get started!

    Very Nice Box - Doubles as a storage case!
    Neatly and safely packaged
    The Edge 540T from Parkflyers.com comes in a very attractive box that also doubles as a storage case.  Upon opening up the box, I took note of how nicely everything was packaged with all the components encased in plastic wrap.   As I removed all the components from their plastic wrapping, I inspected everything for damage.  Everything arrived in perfect shape.   There is a small bag of hardware that I emptied into a plastic food container so I would not lose anything. 
    Interlock the tab from the vertical fin into the horizontal stabilizer.
    Slide the unit into the rear groove in the fuselage.

    The first step in the assembly process is to align the vertical fin into the horizontal stabilizer.  There is a tab on the fin that snaps into the slot on the stab to provide the correct alignment.   Then the fin and stab slide into the slot on the rear of the fuselage as one unit.  Be sure that the elevator control horn is facing the bottom of the plane.

    The tools to assemble the model are included in the kit.
    Secure the tabs from the fin into the fuselage.

    The Edge 540T requires no glue or special tools to assemble the model.   In fact, the tools that are required for the minor assembly steps are included with the kit.    Once the stab/fin is in position, I fastened it in place with the two self-tapping screws - one on either side of the fuselage.   Make sure the screw aligns with the hole in the bottom of the stab on each side. 

    Attach the clevis to the elevator control horn.
    Attach the clevis to the rudder control horn.

    With the stab and fin secured, the next step is to connect the clevis links for the rudder and elevator to their respective control horns.  Be sure to use the innermost hole for each

    The landing gear assembly just pushes into place.
    Connect the tail wheel to the rudder with a U-Clamp.

    The landing gear comes pre-assembled and all you need to do is press it into position just in front of the battery compartment.   The tail wheel's tiller arm is attached to the rudder with the included plastic U-Clamp to provide steering while on the ground.

    Remove the thumb screw to remove the hatch.
    Inside reveals the servos and RX.  Route the aileron servo wire through the fuselage.
    The next step is to attach the main wing to the fuselage.   To do this you must remove the hatch cover by removing the thumb screw just behind the cowl on the top of the fuselage.  

    Editors Note:  When removing the hatch for the first time, be careful not to pry it too hard as it can break.  (Ask me how I know).  The good news is that the repair was fast and easy with some CA.   The model is made of EPP foam which is easy to repair and very durable.   The Stab and fin along with the rudder and elevator are all made from Depron foam.  

    Connect the aileron servo wire to CH 1 on the receiver which is accessed through the bottom access panel.

    With the hatch removed, the wire for the ailerons is routed through the fuselage and connected to channel 1 on the receiver.   The wing can be positioned in place, but be sure that the wire does not run outside the wing once attached to the fuselage. 

    Nylon screw holds the wing to the fuselage.

    The wing is fastened to the fuselage using a single nylon screw at the rear of the wing.  The leading edge of the wing is aligned with a keyway in the fuselage.

    Attach the prop using the included wrench.
    Snap the rubber spinner over the motor shaft
    The propeller is attached to the motor next.  The back of the prop seats into a nut that is on the threaded motor shaft.   Use the included wrench to tighten the nut.  The rubber spinner is pressed over the motor shaft to finish the look of the nose of the airplane.

    The battery will be fully charged in about 90 minutes using the included wall charger.  Once the battery is charged, install it in the hatch on the bottom of the fuselage.

    And that is it - you are ready for the field....  Oh wait.... One more final step (and a real doosey it is!)

    Install 8 AA batteries into the transmitter.

    Let's Go Flying!


    When I got to the field there was virtually no wind to speak of, so I placed the 3 Cell Li-Poly battery pack into the compartment on the bottom of the fuselage and attached the power cable.   There is no on/off switch per se, but the electronic speed control will activate once the power on the transmitter is turned on.  

    I gave a quick check of the control throws and to make sure they were correct.  The ailerons seemed to have more physical throw than the elevator and rudder, but I was not going to make any adjustments until I got it in the air. 

    I placed the plane on a nice piece of grass and advanced the throttle and watched as she leaped into the air.   The little brushless outrunner has quite a bit of power.  More than I expected from a RTF model.    I flew around a couple laps and made some minor trim adjustments.   The plane was very sensitive on the ailerons and seemed as if there was not enough control or response on the elevator or rudder, so I landed and took a look. 

    I remember reading on parkflyers.com's website that they have a pro tip where they suggest cutting off the hinge tape that attaches the elevator and rudder to the stab and fin with a hobby knife and reattaching them with a piece of clear packing tape.  They claim that this will make the movements more free and can increase the control throws.  So that is what I  did.  And low and behold, it was as if I hit a high rate switch on my transmitter. 

    Before getting back into the air, I wanted to tame the aileron throws a bit as even with 3D maneuvers, there was simply too much.  So I removed the wing and then I removed the control horn from the aileron servo.  The stock setting for the aileron control rods is in the outer holes of the horn.  I moved them in to the center hole and figured I would give it a test flight to see how it goes.   When you make this adjustment you need to readjust the clevis on each aileron to center them.    This is where a computer radio would come in handy, with dual rates and end point adjustments. 

    This next flight was much much better.  The elevator and rudder had much more authority and I was really able to wring out this plane.  

    The overall flight characteristics of the model are pretty agile.  It is definitely not a trainer, but it is not a big handful either.    I flew all the basic aerobatic maneuvers including rolls and loops, hammer heads and spins, and they all preformed very well, as you would expect from any aerobatic model.   (I am sorry I am not spending more time going over the basic aerobatic performance, but if you read many reviews, especially in the magazines, they all tend to give the same flight performance - loops are big and round, rolls are axial, etc. So I am not going waste your time on these)

    3D flight was a lot of fun.  The motor/prop combo on the plane provided plenty of thrust to hover and accelerate out of a hover.    Harriers and elevators were also able to be performed but the smaller size of the model made these maneuvers a bit unstable.  Once you get the hang of it, you can correct for the roll to perform these maneuvers a little more gracefully.     Rolling circles are pretty as was the blender.   I wanted to try a second blender but the battery was starting to run low and I did not have the climbing power I needed.   

    Inverted flight was good, but the plane was a bit tail heavy so you needed to be on the elevator control to keep it from climbing or sinking.    There really is no adjustment for the CG, as the battery is fixed in the compartment with no way to move it front or back.   So the only way to make adjustments is to add weight.   I was not going to worry about it as a rearward CG is good for 3D maneuvers anyway.

    Overall the plane flies very well and was really a blast.   The Edge 540T performs more like its larger counterparts than it does a flat-foamy parkflyer.  But that is OK, after all you are flying an Edge 540T that actually looks like an Edge 540T.

    If you love scale aerobatic airplanes, and you are looking for something that you can have ready to fly in minutes, that will perform most of the maneuvers, then the Parkflyers.com Edge 540T is the plane for you.   It is very durable with its EPP Foam fuselage and wing and Depron tail section.   The kit is very complete including the tools that you need to finish it.    The best part is that it comes with a brushless outrunner motor and a 3 cell li-poly battery pack for all out performance.
