    It wasn't long ago that if I was asked my opinion of electric powered airplanes, I would have said, "No thanks". But in the last few years I have been continually amazed by how electric technology has evolved. Nowadays, I welcome the opportunity to fly some of these new electrics.

    Recently I was introduced to the new "Evader" from ElectriFly. My first impression was, "Wow! That is one slick-looking airplane!" The fiberglass body and razor-thin, swept wings really looked impressive. When I was told that it was achieving flight speeds of over 100mph I was really blown away. When I was asked if I would review this little hotrod, I jumped at the chance.

    However, as I write this introduction, the assembly has been completed, but I have not flown it yet - and to be quite honest, I am fairly intimidated by the prospect of the first flight! I have flown planes faster than 100mph before, and I have flown some very fast small planes, but I have never flown a plane this small that would break the 100mph mark!

    Then again, I really LIKE fast airplanes. This should be interesting!

    The packaging was interesting to say the least. What I mistook for a cardboard divider under the wing was actually a cardboard cradle that held the entire contents of the box.



    The Evader includes a bungee launcher as well as the ducted fan unit and an Ammo 24-45-3790kV motor.



    There is also an included plywood cradle, which helps keep the Evader from rolling all over the workbench as you assemble it.




    Manual


    The manual, while very good, does not go into an overabundance of detail. I actually found this to be quite refreshing compared to some of the redundancies of other manuals. I think the reason for this is that this plane is NOT for beginners - or even intermediate fliers for that matter. So if you are putting an Evader together, you should have a good idea of how to assemble a plane by now!


    Download the manual (1mb PDF)





    FAN UNIT ASSEMBLY


    Assembling the fan unit is pretty simple. A few tabs need to be removed both inside and out, so a Dremel Tool can be very beneficial.






    Once the motor is installed, the rear stator fins slide in place and the cone adapter fits over them. Both of these items are then glued in place with CA.



    POWERPLANT INSTALLATION





    Now comes the tricky part. The fan assembly needs to be inserted into the rear of the fuselage. The front fairing on the unit needs a little coaxing to get it passed the rear lip of the air intake, so you'll need to "shoe horn" it in there. Once it is in, it now needs to be aligned with the tail cone. This can only be done from the rear.

    Now that you have gotten everything installed and aligned... You get to take it out again so you can add epoxy to the rear of the cone adapter. Installing it the second time went a bit easier now that I had done it before and in just a few minutes, it was in place.

    Note: Do NOT test the motor at this point, or at least, do not test it at full power. Wait for the epoxy to fully cure first or you will be installing the fan unit a third time! (Don't ask how I found this out!)



    WING ATTACHMENT





    Wing attachment is what you would expect: Glue a dowel in the front, glue a plywood plate to the rear, and screw the wing to the fuse.





    Aileron hook-up is just as easy. A plywood mount is glued around the servo opening, the servo is mounted, and the pre-bent pushrods attach to the torque rods.



    STAB AND ELEVATORS





    With the wing mounted, the stab is inserted through a slot in the fuse. I had to lightly sand the opening to get a good alignment with the wing, then, once properly aligned, the stab is glued in place.

    Now, attach, BUT DO NOT GLUE the elevators with the supplied hinges. The control horns are installed onto the pushrods and the pushrods are inserted into the fuselage. Using the pushrods for alignment, place the control horns in line with the hinge line and press down to mark their locations.

    Handy Tip: The pushrod holes in the control horns are slightly smaller than the pushrods. The manual recommends drilling them out with a #55 drill. - I don't have a #55 drill. So what I do in this situation is to heat the end of the pushrod with a match or Bic lighter and push it through the hole with a twisting motion so that the melted nylon won't stick to it as it cools. If you use a torch to heat the pushrod, be very careful, you do NOT need a lot of heat or you can ruin the horn!





    Now you can drill two holes at the indentations, Harden the holes with thin CA, push the control horn through and secure them with a back plate (which is also CA'd in place).

    The two pushrods are now joined inside the fuse with a wheel collar and attached to the servo. At this point, you can permanently hinge the elevators.



    FINISHING





    There are two wing skids and a tail skid which must now be added. Like many other things, they are aligned, marked, have the covering removed and glued in place. The manual recommends not to skip this step as these skids also add stability for landing.





    The battery, ESC and receiver are installed and the bungee hook is added to the bottom and she's ready! With the recommended equipment, mine balanced perfectly by shifting the battery back about 1/2" for where I had originally placed it.


    You might know it, for the last week we've had some of the nicest weather I've ever seen, but today is cloudy and windy. Time to play the "wait for good weather" game.





    When we finally got a break in the weather, I took the Evader out for her maiden flight. I attached the included bungee cord to the hook, pulled her back as far as I dared, brought her to full power and let her go. As expected, and exactly as described in the manual, the Evader shot forward, dipped toward the ground a bit, recovered, and was airborne. Now it was "Tiger by the tail" time!

    Once comfortably airborne, I pulled back to half-throttle. Fortunately, the Evader needed only a little trim since I was afraid to take my eyes off it! She flies very true and goes where you point it, but you do need to be careful not to let it get too far away!

    After a few circuits at half throttle, I lined up with the runway and poured the coals to her. WOW! I had to make a conscious effort to not be mesmerized by it and turn before it was out of site. Not only is this thing fast, but due to its small size it can quickly get out of visible range, so anyone flying it should be prepared well in advance to turn shortly after it passes. On the back leg, I pulled the throttle back to half again and swallowed my heart.

    Now, a word about "Speed" vs. "Perceived Speed": The human eye perceives speed as how quickly an object displaces its own length. In other words, a 747, which is 225ft long, landing at 150mph will move approximately 225ft in one second. So at 150mph, a 747 will displace its length in one second. This appears to be a relatively slow speed for this giant. Yet at only 100mph, the 30.5 inch Evader will displace its own length in less than .02 (two hundredths) seconds or about 60 times faster than the 747 which is actually flying one-and-a-half times its speed. Another way to look at it is, if you had a 61" long airplane and an Evader that both flew at 100mph, the Evader would APPEAR to be flying twice as fast!

    The reason I mention this is that the Evader is not only very fast, but due to its diminutive size it appears even faster than it is. So this plane is not a Park Flier. It is not for zooming around at the field. If you have a "tight" field or any obstructions I would caution you to find a more open area - You'll need it!

    That said, if you have the right place and a real "Need for Speed", the Evader will give you an adrenalin rush like no other plane I have ever flown!

    When it was time to shoot the video, we were in the midst of several weeks of rainy weather, but one evening, the sky lightened and the winds dropped to practically nothing, so we grabbed the opportunity to get a flight in. Now usually I shoot several minutes of flight and edit out any spots where the plane flew out of frame, or the camera went out of focus, etc., but as soon as I saw the Evader video, I decided to show the entire thing. I think it gives a good idea of how fast this thing really is. You'll notice how even a really good cameraman has a very difficult time keeping up with this little firecracker! AND you'll notice just how quickly the Evader will turn into a tiny dot in the sky!

    I also want to point out that the takeoff was a bit sloppy. This was due to the fact that the ground was saturated with the recent rains, so we were being cautious not to pull the bungee launcher back too far, lest the anchor pull out of the wet ground and impale an otherwise perfectly good assistant.

    Check out the video to see her in action!

    I can sum this plane up in one word - Fast!

    Assembly is straight forward with no real difficulties - the only thing that is slightly tricky is installing the fan unit, but even that was no cause for alarm. Had it not been for allowing time for the epoxy to cure, it could have been built and flown in the same day.

    If you are comfortable with flying very fast planes, you will love the thrill of flying the Evader. If you are moving up to fast planes, crank one of these babies up and hold on to your shorts!

    The Evader is definitely not for beginners or intermediate pilots, nor is it a plane for flying in close quarters. This is a very fast, goes-where-you-point-it airplane. But if you're up for a challenge, it will get your heart pounding like a drum!

    I have about 20 flights on my Evader and I find it to be a great substitute for my turbine-powered models when the weather is just too hot, or time is limited. The second one has been ordered with extra batteries, and I plan to always have one in the car whenever I leave the house. You never know when that need for speed might hit you.
