X-41 Deltastorm


Hi all!

I am starting this thread to hopefully give back to the community that has helped me so much. Thank you everyone!

I call it the X-41 Deltastorm. X for experimental, 41 for my years young, and Deltastorm because every new plane needs a cool name.

This all started a week ago when I was extremely frustrated with my helicopter and I had also totaled my beloved SU-27 Flanker. For a change, I needed to have some fun with this hobby instead of the frustration I had experienced for more than a week. So...I simply whipped-out the blu-core and the xacto and started cutting...no plans, no templates...just some inspiration and limited creativity. I had only one goal in mind: It had to look cool! (IMHO I accomplished this)

I had no idea how well or even if it would fly. I started this last Wednesday night. The weather was very rainy and very windy all the way through the weekend, so I had all my holiday time to work on this. I quickly started having "fun" again with this hobby of mine. I just kept building and building...not really thinking ahead too much, but hopefully enough to not become too much of a pain. By Sunday night she was complete. The weather wouldn't cooperate for the maiden flight until Tuesday. I couldn't wait! I was so excited I had dreams about it Monday night.

Tuesday at lunch I drove to the field and met my friends there for my maiden. That morning, I had even remeasured the entire plane and plugged-in all the numbers into a canard CG calculator I found in the canard thread just to plan for success as much as possible.

I throttled-up and it flew right out of my hand (in a good way). It was quite nose-heavy, but at least it was flying! I landed and adjusted, flew and landed and adjusted some more. It performed better and better after each tweak. I would just break into ear-to-ear grins while I was flying.

After fifteen flights, I've got her dialed-in pretty good. She flies awesome fast...and she flies awesome slow. She flies almost as good inverted as she does right-side-up. She turns on a dime, can accelerate vertically, has a slap-happy roll rate, and does slow high-alpha very well. She also glides like you wouldn't believe...almost to a point where you have to force her out of the sky . And...to boot...this is just about the most forgiving plane I have...thanks to the canards I'm guessing.

This is all a very, very, VERY happy accident...just because I wanted something that looked cool.

On to the numbers:
Length: 30" with motor and prop.
Wingspan: 28"
AUW: 17oz
Power: 2212-06 motor, 30A ESC, 3S 2100mAh 20C (about 230W with a 5.5x4.5 prop)
Paint Scheme: Ukraine SU-27 in honor of my dearly departed Flanker (see my blog).
Paint Used: Anita's All Purpose Acrylic Craft Paint from Hobby Lobby. Finished off with several coats of Minwax Semi-Gloss Polycrylic spray (blue can).
Speed: 134.43kph / 83.53mph (Fastest Doppler result to date).
Canards: Functional via custom mixing with the delta program in my DX7

Make sure you check out the X-42 Build thread as well!

Here are the demonstration videos. I think it's a pretty good representation of the performance envelope of this aircraft. Fast, slow, vertical, glides, etc. I hope you enjoy it.

Holy crap, Dude! THAT's AWESOME! Well done! Very nice all around (design, flight, detailing...)

Do you have any pics of the linkage to the canard stabilators?

That is a super flyer, Bob, It has the good looks of the Firebat but no comparison when it comes to performance. Charles

Beautiful work. I've been toying with an idea for a canard setup where I would run a pushrod from the opposite side of the control arm on each elevon servo, through the fuselage and to the canard on the other side. They would cross each other, one ove the other, through a slot in the fuse. My theory is that in up/down elevator, it would work much as yours does in the controls video, but during hard rolls, the canard and elevon on each side would be oriented the same. has this been done before and do you think it would work better?

Well done indeed, I think the F-15 can take a back seat for a bit........honey where's my knife?

Cheekers,
It has been done and works beautifully. Check out the Star Cobra by Golem https://www.rcgroups.com/forums/showthread.php?t=677608
I don't know if it will work with the control rods on oposing sides of the servo. In the "cobra" both control rods come off the same side of each servo.

Here's couple of pics of mine.

Great new plane! I've seen it fly several times. Impressive!

Sorry I missed the videoing. Thanks for sharing.

Have Bluecor and Xacto and need something bigger than my small electrics for the windyer days, which you've already shown me this plane does well in!

Jim

Looks great, the shape reminds me of the FireFox, which got stolen from the Russians by Clint Eastwood.
