Default RE: DeNight Special 50 ARF by Hangar 9

FINAL ASSEMBLY

The placement of the receiver on the servo deck is basically up to your preference,
as you have more than enough space. I decided to use the new "full range" Spektrum
AR500 since the DeNight, in this electric configuration, only needed4 channels;
2 aileron servos which are on a "Y" connector to the receiver's Aileron channel,
an elevator servo to the Elevator channel and a rudder servo to the Rudder channel.
The ESC is then connected to the Throttle channel, as inthe typical fashion.

Note: Notice the placement of the long antenna leg of the AR500, as it is suggested
that about 1/2 of the length should be oriented in a perpendiular position and in a
slightly different plane, as shown in the photos.

A great feature of the Denight Special is the included battery mounting tray with velcro straps.
There are two little plywood tabs that need to get glued inside the motor box to hold the front of
the tray down in flight, so just follow the excellent instructions and you will have no trouble.

You may have noticed that the Thunder Power 30C LiPo pack has been connected to
the MPI #6970 Arming Switch. This switch has been used successfully in almost
every application when the the LiPo battery has adischarge rate of 25C or more. This
switch allows the user to hook up the fully charged battery and then when ready to
fly, all that is necessary is to plug in the "power pole" key and your electrical system
is armed. This is a great safety feature!

CENTEROFGRAVITY

Caution: Do not inadvertently skip this step! This warning is important as we all have
known someone who has, for some reason, forgotten to properlybalance their plane
before their first flight and subsequent CRASH! Ohhhhhhhh..............Yeahhhhhhhhhh!!!!!

So....do not forget this most important step! My DeNight balanced right on the 2 5/8"
(76mm) mark with no extra weight needed. This is just a smidge (a very technical term)
nose heavy which is OK for a plane with such small wings compared to it's fuselage.

SETTINGTHECONTROLTHROWS


If you have properly adjusted all your servos to the center position before installation,it is suggested
that you try, as best you can, to manually adjust your control linkages to the neutral position before
youadjust the control throws with your transmitter. Thisshould insure that you will only need to
make a few minor trim adjustments during your Maiden flight. The manual suggests the following;


Aileron High Rate

Up 1 inch(25mm)
Down 7/8 inch(22mm)

Aileron Low Rate
Up 3/4 inch(19mm)
Down 5/8 inch(16mm)

Elevator High Rate
Up 13/16 inch(21mm)
Down 13/16inch (21mm)

Elevator Low Rate
Up5/8 inch (16mm)
Down 5/8 inch (16mm)

Rudder High Rate
Up1 1/8 inch(29mm)
Down1 1/8 inch (29mm)

Rudder Low Rate
Up3/4 inch (19mm)
Down3/4 inch (19mm)


Note:
1. Measurements aretaken at the inner or
widest point on the control surface.

2.These are general guidelines measured from
Hangar 9 flight tests. You can experiment with
higher rates to match your preferred flying style.

3.Travel Adjust, Sub-Trim and Dual Rates are
not listed and should be adjusted according to
each individual model and preference.

The weather in Upstate New York has been crazy for the past month and the
Maiden flight has not happened yet, so here are some static photos for now.

We finally got the perfect weather for the Maiden flight and the Chief's Field, in Canandaigua, N.Y.,
was the place. The RC Gypsies had their annual Memorial Day weekend fly-in and all the
"Usual Suspects"
were there. It certainly was a Chamber of Commerce Day and the crowd was
great. Paul Weiganddid the piloting dutiesand with all of his experience with his beautiful Travel Air,
he was the right one with the right stuff! Ohhhhhh....Yeahhhhhh! Greg Covey, the "AMP'D MAN", was
the Videographer (Greg is a man of many talents) and let me tell you with this great crew, the DeNight
Special was in good hands and performed just like a CHAMP!

The DeNight Special proved to be an excellent example of the quality, design and flying
capabilities that Hangar 9 has become known for.Although the DeNight is a 50's style
Formula1 Air Racer, it can also handle any of the demands of a classic Sport Flyer, as
you can see in the attached video.

Very cool video by the way. Today was the day for "my" maiden of my Denight......had a friend that flew mine a few weeks ago & got her all trimmed out. I have to say that this thing flys just awesome. Takeoff was uneventful......little bit of right rudder, and it tracked like an arrow. I got up speed & she lifted right off the ground. The air handling was fantastic. Hands off it was perfect...stable at "slower" speeds & high sppeds. I have not truly tested "slower" yet. I landed hotter than was probably necessary, but it is better safe than sorry.

Very impressive plane. Just wanted to let people know.

AK Leader,

Great description of your DeNight and your post is most appreciated. I sure hope that you were able to
arrange a video and a few photos of your flight! If so, please post them here as I am sure that it
will be appreciated.

The RCCR, our Club, had a big Fun Fly this weekend and our pal Danny Landis flew the DeNight and
also enjoyed how it flew.

Graham,

Your DeNight looks NICE! I do wish you good fortune with your Maiden flight. Our field is grass, but
well manacured, and the one issue that we had on takeoff was the need for some up elevator to keep
the tail down till take off speed was achieved. Other than that, the DeNight is a great flying, classic
looking plane.

Default RE: DeNight Special 50 ARF by Hangar 9

Thanks!

Maiden flight yesterday, 3 flights in total, first was flown by a more experienced pilot from the club, second flight he took off and landed it, I flew it around in between, third flight I took off, flew it around and landed it. After measuring the lipos each time, the flights were 5, 8, and 10 mins respectively.

Flight report:

Conditions: Fog, Overcast, Intermittant Showers ( as always in Ireland ), about 10'c with a light breeze <5kmph

Taking off: Wheel / Pants would get stuck in the grass, but runway hasnt been cut yet and lumpy with moss / sheep hoof prints. We had to hold the plane, put on power, to let it skip off, tail would come up very fast as you predicted, and she wanted to fly after about 15m on 50% power, held it down with elevator till she passed 50m and took off like a rocket on full power, about 40' climbout, 3 clicks of aileron trim, no rudder and no elevator trim required!!

Flying: Setup was as per manual, we found the low rates of the elevator to be too little, and the full rates of the ailerons to be too much ( for now ), so high elev and low rate ailerons, increased the throws of the elevator by 5mm on landing and 2nd and 3rd flights completely on low rates.
Banked turns about 40-50 degrees, and more and she would sink in the turns. She flew straight as a dart, tracked beautifully, inverted beautifuly and rolled axially with no down elevator at all! Much better rolling than my RV8. Looping, tight loops dont work very well, she corkscrews out, so large ( 30-50m+) loops, perfect. She flew straight and maintained altitude at about 55% throttle, or 600 watts with my setup. Flat out at approx 60kmph, but big prop, so might make it smaller with more twist for speed. Very scale like speed, beautiful plane in the air, maybe wish it was a 1.20 or 1.50 size next!

Landing: Stall was very slow and predictable, no snapping, just a lazy roll to the right at about jogging pace. Dont land this plane at walking pace, more like running pace! (see video ).

Settled down on the mains and when stopping, full elevator to stop her nosing over given the runway problems earlier. Big rounds of applause from the club!

General: The quality and scale-ness of my RV-8 kit inspired me to get this plane and share the set of lipos, my next plane will be a hangar-9, maybe the 82" taylorcraft.

Sorry the video is only of the Landing, was busy getting feedback in preparation for my turn on the sticks!

Graham,

What a great Maiden flight, or should I say, THREE flights! In addition, your flight report was excellent and
it gave me a great deal of pleasure to see that your DeNight performed equallyas well as mine. It is always
encouraging for a reviewer to have this kind of positive confirmation that his assessment of the plane was
accurate. Thank you for your wonderful contribution to this build thread. Only, next time you fly your DeNight,
try to get one of your flying pals totake a video of your entire flight and be sure to post it on this thread.
I'm sure we would all like to see it.

I love this model, I'll soon get one to fly at our neighborhood electric field.
Funny, I like the paint scheme but when I saw the real airplane in the 60's it was metallic bronze and cream, not red and white.

I just ordered one and I'm glad to have found this thread!

I have the Sundowner 50 sitting here...but I think the DeNight is going to get built first.

Papajeff, thanks so much for your time in putting together this build thread! I know the Hanger 9 manuals are great, but it always helps to have another set of instructions to look at as well.

Moose,

I hope that you enjoy your DeNight as much as I have. Feel free to add some of your build process to this thread, as we
all learn from each other. If you have any questions or issues with your build, just make a post and I will reply ASAP.

Default RE: DeNight Special 50 ARF by Hangar 9

Jeff, I'm interested in the fact that you didn't need at add any weight to the nose with the power 46. I'm deciding if I'm going to use a bigger motor on 5S. A lot of times, you hear that with a recomended motor, you need to add weight...so I will try to just use a bigger motor. However, that doesn't sound like the case here.

Also, the power 46 and 60 seem to be outdated and the specs of the upcoming Power 52 look REAL good. (more max current then the power 60)

I am also a fan of the Scorpion motors, but what I hate are collet adapters. (both scorpion and eflite)

So, I'm looking at the Cobra motors. The Cobra 4120-14 is reportedly 3g heavier then the Power 46...but can handle 1260 watts and 68 amps. (and a bolt-on prop adapter)

On my lunch break, I'll be tallying data on some Hacker and Motrolfly motors as well.

Default RE: DeNight Special 50 ARF by Hangar 9



Moose,

With the Power 46 and the 60a ESC, we experienced no problem with sufficient power. If you think that you need or
want some additional power, give it a go, but I really can't see any need for it. The retro look and design of the DeNight
is such that I can not recommend any additional weight in the nose using the Power 46. Actually with my set up, the tail
was a little light on takeoff so we had to holdsome up elevator. With a heavier motor, I think that the tail would lift too
high and cause the prop to strike the ground on takeoff. Just a thought before you invest in a bigger heavier motor.

Default RE: DeNight Special 50 ARF by Hangar 9

Hey Jeff,
I just bought the DeNight Special and have been going back and forth on whether to upgrade to motor. I know you say stick with the power 46 but what kind of speeds are you getting? I was hoping to be around 80-85 mph. I was looking at the scorpion motors that others have suggested but im just not sure what to get.
Thanks
Ivan

Here's the thing...I have the power 46 in my Toledo special and I think it's perfect for THAT airframe. It's not a speedster...and it barely feels 'quick' at WOT.

Based on that, I kinda want the DeNight to be a bit more 'exciting' then that. I don't need 125mph, but I'd like close to 100mph out of a dive.

I dunno, I'm just not at all impressed with the power 46.

Velezivan,

I have used the Power 46 with my Toledo and the DeNight without any issues at all. For me, the speed of both planes is
more than adequate. I have never put the radar gun on the DeNight, so I have no idea of the true WOT speed, but it is
just fine for me. I would check out the specs on the Scorpion motors and compare the WEIGHT as I believe that if the
more powerful Scorpion motor is more than 10% heavier than the Power 46.........you may very well need some extra
weight in the tail.

Well I just ordered the scorpion s 4020-10 for $99 so I just couldnt pass it up since they go for 150 everywhere now. its just slightly heavier than the power 46 but not much.290g vs 304g. hopefully ill start the build by the end of this month. do i need to go with a 100 amp esc or can i go lower? not sure which brand to go with. Any suggestions? is it worthwile to go with scorpion esc? if so which one?
