Sure NP! Check out this Gdrive link with all the files I made for the Mini Arrow. I printed the Rear covers with TPU, but you can probably use PLA. drive.google.com/drive/folders/1gerU3DIOYZsouzvfFOaCnEhO57slEcrn?usp=drive_link

Thanks! What kind of radio link are you using? I'm using TBS Crossfire Nano RX so I've never had a failsafe.

I'm using the radiomaster tx16s with a ND ears transmitter 915mhz, I don't expect to failsafe but flying in the mountains it's very possible when flying 6 to 8 miles each way waypoint mission

@@egtreadway4232 I suppose that is part of the thrill when you get your craft back in one piece. Check elevation graphs in the mission planner and always be sure to set your RTH settings correctly if you do end up going behind a ridge and triggering failsafe. Good luck!

I'm not totally sure, but this is how FliteTest designed it in their plans. The under camber helps reduce stalling at low speeds. Also an easy spot to install the aileron servos.

I've got all the bugs worked out. She's flying great now! Thanks for watching.

Winter where I'm at currently is long and cold...no flying at all. Things are warming up but I'm just dealing with life stuff, hopefully I can get back on track soon.

@@LiftVector good to hear..,keep warm

Thanks man! I just can't afford moving into digital at the moment, one day I'll get into it and I can't wait to try. I built another Spear and mounted the antenna vertically (look at my other vids). Although I've never had issues, even 3-4 miles out in horizontal config, I do get less telemetry drops in vertical. All my quads have horizontal Crossfire antennas and when I built this wing I just went that way since I've never had issues with range. But yea, vertical now for my wing builds.

The lw-pla is tougher than the single foam winglets. I was getting creases and bends in the foam on my 1st spear with rough landings. 2 top/bottom layers, 15-20% infill and I believe 3 perimeters or 2. Hot glued the winglets (I punched tiny holes in the side of the prints so the glue had something to adhere to).

@@LiftVector Thank you for your message!!! So no worries with hot glue to melt that lw-pla, that's good to know. I can switch my hot glue gun to lower temp just to be safe:)

Hello again! Your front fpv camera is poiting exactly forward or is it at an angle pointing down? On the stl files you have a camera mount pointing at an angle, that's why I'm asking. Thanks a lot

@@TrupaVisatori It is angled slightly down. Maybe 5-10 degrees.

Thanks for your answer. Is there a reason of pointing slightly down or is just personal preference to see more ground? By the way, really like your vertical fins instead of the original foamboard! 3d printing + foamboard is the way😉 waiting for your next flights!

Thanks for watching! I hope the STLs are useful for your builds.

Thank you! I painted the plane in my garage on a warm summer day. Start off with a very light coat so the paper doesn't soak up too much paint and bubble/warp. Wait about 5-10 min between coats. Keep adding light layers/coats of paint until the full color looks nice. I used Rust-o-leum 2x paint/primer all in one. The black and white sections are vinyl tape I bought from Amazon. The windows are silver vinyl tape from Hobby Lobby. Hope this helps. Always start with ultra light sprays and build up slowly! Use tape for smaller details.

Thank you very much, great tips!!! Yeah, now I know why my last plane had a curved wing. (too much paint from layer 1🤦‍♂️) Sorry for my late reply. If I will have issues with my Explorer, I will come back to you straight away. Looking forward for your next videos!🧐

20 x 30 x 3/16" Adam's Ready Board from the dollar store.

Thanks! 3d printing is great for the RC hobby. It takes awhile to get things right, but it is worth it.

I watched this video. czcams.com/video/BuT_T3DERjg/video.htmlsi=gy4UB5t4O226aZW9

I have flown this plane a few times now. It is setup really well! RTH, Loiter, FBWA and missions work perfectly. Thanks for watching.

OK i understand but my question is if you test crius aio module with megapirate from multirotor

Oh, sorry I didn't understand. No I haven't tried that. This is my 1st Arduplane I've built and I only used the Radiolink firmware and Mission planner from Radiolink. No quadcopters built for this yet.@@mrz2528

That's awesome man! The weather is getting warmer and I built another one, haha. Mini Arrow #4 is ready to go!

Thanks for checking out the video!

@@LiftVector no Problem 😎 you did a great job and 💯% good content to 👍🏻👍🏻

Hello, I don't have the time to make a video on this right now. Here is the video I watched to set this up. czcams.com/video/kSNDo93Zk54/video.htmlsi=dzMGXQMewjSCSMd9

Hi, I appreciate you asking. But it would take quite a few hours in labor to setup the prints and ship, and at least 20+ hours of printing time. I've never calculated my costs for something like this but it wouldn't be cheap enough to be worth it for you. I also don't have the right filament on hand.

This craft has a 40 A ESC and a 3s 3200 mAh Lipo. I'm thinking you would be ok. It can take 2s-6s on their specs. You could also check specs here: www.mateksys.com/?portfolio=f411-wse#tab-id-1

Autolaunch will time-out and switch to whatever mode your switch is on. In the modes tab you can assign a switch to things like angle, manual and acro. I have a switch for this and use that to bounce around those modes. You could also set a switch for loiter or RTH if you feel like you might crash. But angle might be better for a saving moment so you can still have control if there are trees or obstacles around. Look up INAV modes on CZcams, you will find plenty of videos.

I will have to try that, thanks for the tip!

Hello, thanks for watching. I have flown this plane several times now with the Crossflight FC and having exceptional performance. RTH, Loiter and mission waypoints are working perfectly! The plane flies wonderfully and I still haven't done an autotune. The error you saw was from my receiver due to faulty soldering and has been fixed. The compass works properly with calibration. I am using Mission Planner 1.3.80 from Radiolink and their firmware Airplane-4.3.7. I'm hoping to do another video with this plane and hardware one day.

@@LiftVector thank you soo much for sharing

What size battery are you using? Is your CG correct? Mine is slightly nose-heavy, just barely.

@@LiftVector yes i checked the cg its correct but when motor rotate it pushed the plane down side.

@@cosmogaming6705That leads me to suspect your motor thrust angle is off. If possible, remove the motor pod and watch the flitetest build video to make sure you mounted it at the proper angle.

@@LiftVector Ok👍

Thanks! I used lightweight PLA (Polymaker) for the winglets and vertical fins. Regular PLA (Sunlu) for all the other parts.

The orange sections are vinyl tape from Amazon. The black accents are 3d printed shapes (2 layers thick) I modeled in Blender. These were CA glued on.

Thank you! Haha, sounds like a true bush plane.

Thanks for watching. The Flitetest Spear is a fun wing to fly. Here are the free plans and build video on how to make this delta wing. It takes a lot of commitment and time, good luck! www.flitetest.com/articles/ft-spear-build

Thanks for watching. That is a good description, I'd have to agree!

Thanks! I don't have braking setup for this ESC. The prop always strikes the ground at some point. This is fairly normal and I've never had a prop snap on landing.

Thanks for watching. I decided to make a video showing the craft in action due to the abundance of 'how-to' resources I found. I highly recommend these two channels which taught me all the technical aspects of INAV. www.youtube.com/@Painless360 www.youtube.com/@MrD

Thanks for watching!

Thanks! I appreciate the feedback.

No worries. These waypoints (landmarks) were plotted out prior to the flight in Google maps so my spotter and I had a defined flight plan to follow. We also printed out the map beforehand. It wasn't a mission in the flight controller. I then attempted to fly the exact mission plan we prepared by memory and landmarks. Think of it as me showing the manual flight plan with waypoints prepared for this flight and location. Thanks for watching!

Thanks for watching! I still have them stored away in the box. I've tried the floats and it was a lot of fun. I'll have to watch a video about how the plane performs with the slats. Most pilots seem to fly without them, I've noticed.

Thanks for watching!
