Great Planes Electrifly Reflection |
Lately I've been looking at small electric planes, trying to figure out which one I wanted. Every time I saw a new one it looked like exactly what I want. I wanted something very light weight that can do some amazing 3D maneuvers. I don't care about indoor flight, I want to fly outside when the wind is down. I don't know much about electrics at this point, since I've always been using glow fuel. I have an electric MS Hornet, but it's actually pretty pathetic. The plane that caught my eye was the Reflection. When I talked to my friend Mark about it and found out he's looking at the same plane, I knew I was on the right track. That's because Mark has a lot of electric plane experience. We both decided to get the same plane, which should be fun.
04/16/2006 - Parts ordered
After a nice Easter Sunday with extended family, I came home and placed my order
on Towerhobbies.com. I ordered the plane, a RimFire motor, Phoenix 25 ESC,
2 Cell Pro 640mAh 3S batteries, a pack of 6 propellers and a bunch of
miscellaneous building materials.
04/17/2006 - More orders
I realized this morning that I forgot to order DuraTrax Powerpole connectors.
I called Tower to see if I could add to the order and they said, "no". I
placed a new order and paid another $4 for shipping. ARG!
I also ordered my Cell Pro 4S cell balancing charger from FMA Direct. It's on backorder, but there's a chance it'll be here before the plane is ready to fly.
04/18/2006 - Parts arrived, started construction
The main package arrived today with the plane, the batteries, ESC, etc. I
started building the plane and got quite a bit done. The servos aren't
here yet, so construction is on hold until Friday.
Build notes
04/19/2006 - More construction
Mostly what I did today was learn about charging Li-Po batteries. I did
get some construction done though. The motor is on, the ESC is mounted and
the battery is mounted. I soldered my connectors on the motor, ESC and one
of the batteries. I had a 50% chance that I wired the motor to run in the
right direction, no luck. After bench testing, I switched two of the wires
and had it spinning correctly.
04/20/2006 - Charge station
I made my charge station today. I converted an ATX PC power supply to
provide the 12VDC. I installed a cigarette lighter plug into the case and
hung it on the wall. Next to it is my ammo box working as a battery
bunker. On top of that is the Triton charger (CellPro 4S is on backorder).
04/22/2006 - Finished building, first flight
UPS lost my Futaba S3110 servos in Vernon, CA so I bought 3 Hitec HS-55 servos
at a local hobby shop. The Futaba's should be here early next week.
After finishing the build, I decided to fly it in front of the house. At
first, when I throttled up, I noticed the rudder shift over. Turns out I
had programmed a helicopter mode on my 8UAPS and didn't realize it. I
switched it to ACRO and reset the dual rates. I took off and the CG seemed
to me to be too far back. I also noticed that the ailerons don't return to
center completely. If I bank right, then let go, it's still just a touch
to the right. Same happens when I go left. I think the control horn
doesn't fit on the servo as well as it should. Anyways, I flew 2 patterns
around the cul-de-sac and missed the light pole by inches. After landing I
shifted the battery forward a bit and flew one more pattern around the
cul-de-sac. The wind was just too gusty and unpredictable for a maiden
flight.

04/23/06 - More flights
I flew two flights this morning. The plane is much more docile since I
moved the battery down to the horizontal fuse. I had the battery up under
the top wing as I heard recommended in a review. BTW, when I say "docile",
it's a relative term. This plane is still a handful to fly, but that's
because it's incredibly capable. I noticed on knife edge that it pushes
the nose down fairly hard. This is either because I've got my CG too far
forward (learning to fly it), or because the battery is lower. I'll live
with that performance until I get more use to flying it.
One of the biggest differences between this and anything else I've ever flown is that this plane does not "slip" in turns. Apparently I've always slipped my turns on fixed wing aircraft. Now that I'm flying this plane, turning is different. I already know how to coordinate turns (especially from flying helis), but I've just never bothered. When I roll this plane over about 45 degrees, it just keeps flying straight ahead due to the vertical fuse sides. Today I started using a lot more rudder in the turns and I'm able to keep the plane closer to me.
During my second flight today I was feeling much more comfortable and confident with the plane. I walked over to the dirt field and flew around at a much slower speed. I even hovered it at waist height for 20 seconds or so. I took it up high and did a few tight rudder turns. Even at the recommended low rates, it cranked around in a circle in about 10 feet. During my first flight I cranked the elevator and pulled a fairly tight loop. I decided to try high rates. When I cranked the elevator, the motor quit. I chopped the throttle and brought it back up. Since the throttle came back I figured I was low on battery power.
04/25/06 - Battery connectors
The
Powerpole connectors looked kinda funny on the tiny battery wires.
Today I switched all connections over to
Micro
Deans instead. The new connectors will require two hands to disconnect
them, but they're sized more appropriately and they weigh about half the
Powerpoles.
04/26/06 - Charger
I learned today that the 640mAh 3S batteries I've bought can be charged at 3C
instead of 1C. I had on order an FMA Direct CellPro 4S charger, but it's
backordered until at least the end of the month. The BalancePro 6S charger
will charge at a 3C rate, so I ordered it from Tower. I won't be able to
charge with it right away though because the BalancePro-to-CellPro adaptor is
also on backorder.
04/29/06 - Flights
Flew a few flights this morning.
04/30/06 - More flights
Flew about 7 flights today. During one flight the o-ring that holds the
propeller broke and I made a quick landing. That flight made me want to
disable low-rates. If I wasn't in hi-rates I would have nosed in hard.
On a few other flights I had this weird rudder flutter problem. I was
hovering, then I'd throttle up hard and nose over a tight outside loop/flip back
into hover. On a few occasions this caused the rudder to flutter and bring
the plane down. I was able to control it enough that the landing didn't
damage anything. One time I took it up real high and made it flutter
again. On the decent I worked the rudder, elevator and throttle to try to
get it to stop but nothing worked. Then, I couldn't get it to flutter
anymore.
05/03/06 - Landing gear support
Last time I flew I added a rubber band to the landing gear so it wouldn't
completely collapse on landing and nose over. Today I exchanged the rubber
band for a piece of carbon rod. I used "Spider Wire" to hold everything
together. I also spider-wired the landing legs where to pass through the
lower wing and through the center fuselage carbon rod.
06/02/06 - Lots of flights
I've flown almost every weekend over the last month. Nothing really new
except I'm getting smoother and smoother flying this little bugger. I've
finally got my BalancePro 6S charger up and running as well. The other day
I ordered a new Reflection kit because they are so cheap now. It arrived
yesterday and I'll build it sometime soon so it's ready to take over duties.
06/03/06 - A few flights
Flew a few batteries out this morning
06/04/06 - Prop problems
I flew a few batteries out today, but I started having the prop problem again.
The prop wobbles off the "prop saver" mount and I have to dead stick land.
I switched the dual little rubber bands I've been using for a fat o-ring.
At the end of the day I noticed that the o-ring had broken too. I'll have
to figure something else out.
06/13/06 - New transmitter
I configured the Reflection on the new Futaba 12ZH radio today. I also
removed the Phoenix-25 ESC. Mark is going to use the 25 in his little 540
plane and he bought me a Thunderbird-9. It's the least I could do since he
gave me a ready to fly Shogun v2!
06/17/06 - One flight
I flew one flight today to verify the new 12Z radio and it's settings.
I didn't get the expo right because it was real touchy. When I got home I
checked the 8U radio and discovered I had -40% expo and I only setup -25% on the
12Z. I like the way it flew on the 8U, so I'll match the old setting.
Everything else seemed to work great.
06/25/06 - Lots of flights
Mark and I flew the Reflections a bunch today. We got out the chairs and
sat and flew. At one point we set out a 12oz water bottle and tried to
knock it over with the rudder (while hanging from the prop). I managed to
knock it over and although I was trying on purpose, I knew I got lucky.
Then Mark got out the video camera and I had to work and work to hit it again.
But I managed to and Mark says he got it on video. I'll get a video online
when I can.
08/12/06 - Update
I've flown a lot over the past 6 weeks, but I actually have pictures from
today's flights.
08/13/06 - Several flights, including a final flight
Mom and John came to visit this weekend. We went out flying in the morning
to the construction site near Mark's house. I flew the Reflection quite a
few times and had to make several repairs. One time I tried to take off on
the dirt and it ripped the rudder off the back of the plane. I forgot that
I don't have a wheel back there anymore. After several more flights and
more and more glue, I decided that I wasn't going to glue it anymore. The
leading edge carbon rod was hanging off, the landing gear cross support had
split in half, one aileron was dangling from one hinge, but it still flew!
On the final flight I was bouncing the rudder off the dirt while hanging from
the prop and the rudder fell off. I flew around a little longer, laughing
away. I had no yaw control and it kept flying in about a 40 foot diameter
circle. I tried to lean the plane to the side to compensate, but this
plane doesn't work that way with the vertical fuse. I finally decided to
line up my curved landing approach and actually landed the plane fairly
gracefully.
The reason I didn't want to glue this plane anymore is because it's had
several fractures and it's just not worth fixing anymore. I have another
Reflection kit sitting on the shelf, so it's time to start building it.
07/10/07 - Summary
Over the past almost 1 year I flew the 2nd Reflection many, many, many times.
It met it's doom during a garage sale a couple month ago preparing for our move
up North. Lucas (my 2.5 year old son) was allowed to play in the Jeep.
Unfortunately the Reflection was sitting in the back seat at the time. He
saw fit to rip the poor plane to pieces. I boxed up all the parts and
worked on the move to Rocklin, CA instead.
A few weeks ago I ordered my 3rd Reflection and about a week ago I assembled it and flew it (while on a camping trip at Dinkey Creek, CA).
03/16/08 - Another Summary
I've flown the 3rd Reflection several times over the past 8 months. A
rough tail-first landing in tall grass really did a number on the back of the
plane. I attempted to glue and tape it back together, but then realized
that the rudder was glued straight ahead. I started digging into that
problem and broke all my repairs. I opted instead to order a replacement
plane. After finding out that the Reflection is discontinued, I ordered
the CAP580 instead. It's a real shame that the Reflection is discontinued
because I really like the plane. As a matter of fact, after stripping the
motor, speed control and receiver from the plane, I worked more carefully on the
rudder and I think I have it in flyable shape. I broke down and ordered
another RimFire motor, Thunderbird-9 speed control and a Berg 4-channel
receiver.
03/26/08 - New electronics installed
I received the new receiver, motor and speed control from Tower the
other day. I installed the motor and receiver. I had ordered the
bullet connectors for the speed control, but they sent the male connectors
instead of the female. I stopped at the local hobby shop on Monday and
picked up the female connectors. One of these days I'll wrap up the wiring
on this plane and it'll be flyable again.
04/14/09 - Summary
I flew the Reflection quite a few more times after fixing the rudder.
I've been eying the GP Pluma though. Since this 4th Reflection has gotten
heavier and heavier, I figured it's days were numbered. What better plane
to fly inside a 50' x 32' building with a 15' ceiling. That was a lot of
fun, but it took it's toll. I managed to find a guy in North Carolina that
had a new Reflection kit though (and a reasonable price). I ordered it up
and someday I'll build it. For now, the guts from the Reflection have gone
to the Pluma.
