This is my declaration for this years Build-ruary Build Challenge. As the first three days I will be out on business (may favorite most Energetic Time)
  1. FT- LongEZ
  2. FDM DTFB Prandlt-D (swept back)
  3. Perdona - Depron B2 Bomber - or EPP 3d flyer. S-Diy F-117 Nighthawk

Build 1 (Long EZ) (2/10,2/11)
This is the kit I picked up as a volunteer from FT for being a volunteer. I planned on using the pieces to cut out 18 for the Cub Scout pack STEM. As this will be the plane we build this year.
IMG_20230207_001445690.jpg

After my tried and true band saw, cut-9-Planes-at-a-go method, we were ready.

Cut 1 set
IMG_20230209_005955302.jpg
2 sets, 18 kits Counted
IMG_20230210_150714011.jpg
And score cut. Ready!

Wait! I still haven't built one yet.
So during the Aviation RC Noob Podcast Buildruary Build Party, I built two. Wired up one for RC fully. The chuck glider one, I build using tape as much as possible. I used glue to glue down the top and bottoms. And the winglet. That was all, because I want k-5 graders using hot glue as little as possible. It's their build not the parents.

RC normal build out. A-pack motor.

All three

Then for the STEM day I brought a number of planes to show them (and the parents) where they can take it.

Flight:
Chuck Gliders
Here are the Maiden flights of the chuck gliders the red one is the test model. The yellow and orange is the Demo. Both flew great with 1 nickel of weight at the nose.

RC Version

Debrief of the chuck gliders:
The kids planes all flew well, and were/are durable. As a Chuck glider it was perfect.
Debrief of the RC version:
IMG_20230215_114821225.jpg IMG_20230215_114801581.jpg
  • Torque roll made this impossible to launch right for me. If this were my first RC kit, I would be very disappointed.
  • It is Durable. There were 5 hard nose-ins before I saw real damage. I could have added doublers to the nose for more strength.
  • Use a thicker BBQ skewer along the canard.
  • Use a lighter 2S battery.
  • Velcro the esc so a crash won't unplug the motor wires.

Build 2 - DTFB Prandlt - D
Pieces cut out
IMG_20230226_105233965.jpg IMG_20230226_105251733.jpg
Edged ironed
IMG_20230226_105313815.jpg IMG_20230226_105307308.jpg
not all parts we perfect from the plans. Here are some of the fixes
IMG_20230226_120336448.jpg
Trim spars to fit
IMG_20230226_122708462.jpg
Time to glue in the spars and foster the twist IMG_20230226_123010080.jpg IMG_20230226_124359929.jpg IMG_20230226_124404696.jpg
Sections fro each end

Almost finished product
IMG_20230227_113900180.jpg

It needs a battery hatch, and the motor mounted.

IMG_20230227_230643083.jpg


Maiden flight:

Take aways:
I need to update the plans for the adjustments. I should spend some more time to include the parts that create a reproducible twist.

I think the balance spots are good, I flew it a bit tail heavy. It would have been better with more nose weight.

Lastly. Low rates. Use low rates for serious proverse yawing action! Now I should be able to build your own with confidence.

PS - the added weight didn't seem to help.

Build 3 (B2 Stealth Bomber)

I will be building the B2 stealth bomber by Julius Perdana fro YouTube. Plans are available from a link in the vids.
2/4
I have a small pile of depron, so I taped the sheets.

2/6
got on with some Build-ruary builders on the ARCN discord and started placing them on the depron. A total of 6 massive sheets. As everything was 2X times. Easier to cut them at once.
*2/12
Finally got cutting. Including the ply.*

2/16 - I may need to punt on this. I have cut out the F-117 from this vid, which I plan to install and EDF instead of the prop-in-slot.
You can find the Build Video and a link to the plans - Here
IMG_20230217_153439407.jpg
2/19 - Build Morning
Below is the EDF break wall between intake and exhaust. (Parts beyond the plan) it is installed right behind the intake opening. It should be 3/16" taller.
IMG_20230218_110143733.jpg IMG_20230218_115627834.jpg
I set the EDF on either side using Kraft sticks.
Glued between a foam pillar. The fuse roof pins it in.

IMG_20230218_122139786.jpg
I also had to add a dart on the top to expand the surface to accommodate the EDF.
I then needed to add the rear panel as the plans stop at the motor slot. Which looks like this:
IMG_20230218_134659795.jpg
I think it came out well. A bit more tape than I wanted.

IMG_20230220_004207665.jpg

To get this airborne, I need to install some landing gear.

Maiden:

Damage Report:
the nose is from the glide /c.g. Test.
IMG_20230227_113832253.jpg IMG_20230227_122544912.jpg
I found another EDF, (64mm with a 4S) and swapped them out, and messed another RX sucking it into the EDF. And shaved some wires.

This is just destined not to be...

Take away:
Great Build. 2 pieces of foam for a great look. If you make it with an EDF. Build out the intakes to protect the battery and RX from getting sucked.

Final Looks:
I love yellow orange... So here it is!

IMG_20230220_002311397.jpg

Take-aways:
Generally speaking you need to put a decent amount of reflex to make this fly right and I had a lot more right reflex to get it to fly level as there's a lot of torque roll.
As you can see it's still flies great. Once I nail this down it's going to make a great beginner plane and fpv plane.

I have built my first three planes. In two days. Two are chuck gliders and have flown (see post 2.) The other is the complete RC version. It is ready to see fairer weather for a maiden flight. Should be soon.

This looks like a great way to use your talents. Thank you for giving back to these kids.

Flight debrief in the build post.

This can be a frustrating hobby for sure. Don’t be too hard on yourself for “venting” a bit. We are emotional creatures and it is okay to show them from time to time. When things go good we smile and laugh. When things build up a bit and it goes against us….it’s okay to let yourself be disappointed. The light and the dark….the good and the bad….the Ying and the Yang….it’s all the same thing.
I do love the Long Ez airframe. But even the most beautiful airframe can test our will.

Thank you for the video Matt.

F-117 has wheels. And servos are ready. I only had 1 hr. Productive, but not as much as I hoped. Gluing tomorrow. Weather will be perfect for a maiden or two.

Coffee will play a critical role.

I forgot to take pictures but the prandal t is cut out folded servos are working and I'm just need to essentially glue it and attach the surfaces. So my estimate about halfway there I should be able to finish it tomorrow and with any luck made in it.
