Building a DIY REAPER Drone... Ended Badly

[@RusstickDoom]

You did a stellar job building that reaper. Beef up your landing gear and get the one 6 cell in just the right spot and you’ll have an amazing plane. It looked like it had very well performing flying characteristics for a maiden. If you decide to start over, go bigger! Bigger planes are easier to fly.

[@leezensmith775]

i agree with the bigger statement, not only does a bigger size mean one or even two 6 cells bat. you could have bigger landing gears to the increased size, more avionics, 3d print the parts out of the rugged light PLA, and maybe some memory to have a time laps of the flight.

[@1pcfred]

I was thinking the same thing. Make it bigger.

[@TCeries-plays]

yes It would also help to generate more lift and also enhancing controls of the aircraft👌👌

[@honestiguana]

You need a launchpad, urgently. Try and make one using a rail made of wood and rubber, some kind of slingshot, to eliminate the risk of a wigly throw, like the one that killed this plane.

[@NavyFE]

Agreed, CG should be addressed before any launch. We never took off before I did the CG worksheet before takeoff in the Navy.

[@motionsic]

Very informative video showing a very clean and impressive build. However, two things stood out to me (as a RC flyer with two decades of flying experience). 1. The linkage setup on V-tail is the worst possible combination. With link on outermost hole on servo horn and almost inner most hole on control horn, this gives the servo the worst mechanical advantage. Making the servo prone to failure and ruddervators prone to flutter. 2. Hand launching a pusher prop plane with prop at lowest point and a heavy setup is a very bad combo that can result in severe hand injury. A crashed plane is the least of your worries. Otherwise, keep up the great work!

[@OFCIFR]

depends if hand launch is turned on in the firmware which will turn the engine only once it has left your hand

[@iforce2d]

I'm actually calling tail heavy on this one. As it left your hand the attitude changed quite quickly, rather than the stable dart like behavior that nose heavy would cause. All your control inputs were correct, the fact that it couldn't pitch up in time was just due to low airspeed (pusher prop giving no flow over the elevator). To check the CG of a scratch build, balance the plane on two fingers so that it's level, then shove it quickly directly upward, it should nose up just a little. You can also let it drop downward if that's easier - in either case you want the nose to lead slightly, and the tail to follow. Regarding the damage, it seems like the only connection between adjacent segments of the fuselage was the flimsy plywood frame? At least run some packing tape length-wise all the way down, would help a lot. Adding a vertical fin under the tail would save the prop, although perhaps spoil the look you're going for. Anyway it does look great!

[@RCP-1136]

Also the camera on the wing probably did not help

[@spyder000069]

@@RCP-1136 Agreed. 1. That camera on the wing would need the same amount of weight on the opposite wing. 2. A lot of arc in that throw and didn't throw it wings level so basically threw it into a stall with the extra battery weight as well. 3. Threw it at full throttle with a 3 blade prop means a lot of motor torque roll from the heavier prop and motor speed. In my experience with wings and mini talons I run about 70% throttle on just a slightly elevated launch (not far from level) and then by the time both hands are on the transmitter I can pin the throttle and things are stable.

[@SaveAllTheWolves]

AWESOME! Iforce2d makes a good point consistent with the documentation I recently studied to obtain a private pilots license. The prop being behind the Ruddervators doesn’t supply “forced” airflow across them so they aren’t as effective at low airspeeds. Also when a plane loses power, the first thing a pilot is taught to do is bring the nose down, but it appeared that your unit, due to too much aft weight, pitched up at low speed. The FAA has some very helpful information about the necessary correct balance of a plane and it’s free www.faa.gov/regulations_policies/handbooks_manuals/aviation/phak/media/12_phak_ch10.pdf

[@jimhenriksen498]

Oh Michael, the fact that your design flew so well in most of your video was inspiring! The reason why we (used to) build out of balsa wood is because of it's "strength to weight" ratio, nothing beats it in the flying arena. However, and bottom line here Michael (because everyone gave you such wonderful advice within their comments) is that #1-check your C/G (center of gravity). To start with your maiden, go with 25% of the forward wing in front of your C/G; this will cause your bird to be a bit "nose heavy" but better nose heavy that tail heavy Michael! #2 Once you have the C/G where you want it, be absolutely sure that your plane balance laterally (I noticed that you had a camera on the starboard wing) the weight and drag of that camera will cause the aircraft to yaw to the "right," be sure that you suspend the craft from the nose and the tail down the centerline to check balance. I would bet that if you built the craft balanced, right to left, that you had to trim in a lot of left aileron/rudder to get it to fly level. I could be wrong; you very well may not have built it equally balanced on both right and left sides! Me personally; I would leave the camera off, too much weight and drag for the benefit! #3 A heavy plane made from epoxy, hot glue, lite-ply & paint will need a bit of a roll-out before you rotate into the air; but have faith Michael, (given, the forgoing guidelines are followed) rotate it will! Now here's the kicker Michael; the heavier you build it, the less "acrobatics" it's going to want to do, lighter is a good thing. However, you can go too light, so use your head and think your way through this and you'll be fine. Oh also; batteries are (usually) Lipos, but not all batteries of the same "described/advertised" value are the same size and weight, you've probably discovered that by now. Do some research and find batteries that are of the "voltage/4S-6S" value that your and use as light as you can get! Also, that plane is what, about 2 meters wingspan? A Raptor is basically a glider design; if you're motor is designed to run on 14.8v then use 4S batteries, if it is designed to run on 22.2v then use 6S batteries. Also, please be sure that your ESC can handle whatever battery you decide to use; otherwise you will burn it out and your plane will crater in like you've never seen before! Finally, and this is a bit of a reach if you don't have one already; get yourself a "watt-meter" Michael, charge your battery up to maximum and place the watt-meter between your ESC and your battery and see what Watts/Amps you're drawing at full power. Oh, I almost forgot... since you're powering a prop motor, the "C value" on your batteries don't have to be more than 45-50C, any more than that and you'll have enough go juice to power up an EDF, which you're not using! Great project Michael! With your attitude, spirit for adventure and obvious intelligence; you'll go far! Remember, a good pilot learns from his mistakes; he then utilizes this knowledge to become a better pilot!

Hi Michael, my 82yr old machinist dad and I have been building and flying (and crashing. Lots of crashing.) foamboard planes for about 3 years now. Our passion project is the Bugatti 100P and we're on the third iteration with counter rotating props. So far our fuselage designs have, well, sucked, and I really appreciate your frame and foamboard skin approach. The Reaper turned out amazing and it hurt my heart to see it crash. What would it take to entice you to do a video of your design process, particularly how you land on the correct size/shape foamboard skin components? Any other advice or direction you could provide would be vastly appreciated!

[@michaelparker5963]

Not sure if anyone brought this up, but you seem to be lacking a flight control surface dedicated solely to yaw control. It would seem you have roll and pitch covered, but the V shaped elevators will only produce so much yaw, and not at a perpendicular angle to the Z axis in flight. I would recommend adding a rudder directly under the fuselage below the elevators at the rear. This should give you full yaw authority in any crosswind flying conditions.

[@JayReding]

That's an awesome project! The last flight was definitely too heavy. Adding a higher cell count probably isn't necessary for something like that. Depending on what your amp draw is you might want to consider using something like a 3S 18650 pack, you can get a huge amount of flight time so long as you're not really pushing the amp draw to more than the cells can handle. You might also want to consider doing more with the LW-PLA. I bet you could save some overall weight by using LW-PLA panels instead of foam board. This might be a good design for a launch rail or even a high start bungee launch. Hand launching is always hit or miss, and I really hate having to hand launch something with a pusher prop. Hope you build a second version - that first one turned out fantastic other than being a bit too heavy with a big pack.

Your landing gear def needs help. Go look at the planes that land at that range, and see what they do. My guess Is to tune up the suspension (use flexible metal straps) for the suspension, which will absorb a landing instead of bouncing around. I love projects like this. This project is so much easier to control and program than a drone because it is more stable in the air given a velocity, and this has more energy capacity as it isnt' using all its energy to push down 100% of the time. You need to put on lights, a couple fireworks, a trailing advertisement, or do some cropdusting. Some farmers have switched to drones for crop dusting which is amazing.

[@brandonb417]

I probably wouldn't change much, just use carbon rods to hold the bulkheads together, that will give you some added strength down the fuselage. Also, make sure you do a balance check every time you change something, it looked like you were so nose heavy the full up elevator wasn't enough.

[@stetsonscott8209]

I developed a method for doing bevels with the laser on wood. You need a nearly perfect feed/speed setting to cut the wood at thickness (so that it isn't over or under penetrating). In the case of an interface that uses a pdf document, the area of the bevel needs to be covered by the line weight and the line needs to have a 0-100 gradient stroke effect. This means that a Lazer driven by black opacity will start at 0 and then slowly get hotter as it approaches 100 opacity. Speed must be set to allow for cooling depending on material

This is just a stepping stone to a better version. You learned a lot and a new version will be definitely better than this one. A few suggestions from me: make it bigger. The size is too small for a start on grass, double the size and you can fly anywhere. Using plywood this thin might be light, but laminated aluminium or carbon will be much better. It’s more expensive, but it provides a much better and sturdier frame. Lastly, if you make changes in the weight, take out the guesswork of balancing. Make sure your plane is balanced properly before you fly this thing. Keep on going with this great idea, I am looking forward for the next version.

I would like to suggest you add solar panels to your design and a PCB way charging board that you'd need to create that would be controlled to only charge after the battery gets to a certain level and turn off at a certain higher level. I would also suggest you weigh your electronics and battery and find your plane's center of gravity then add your electronics accordingly to balance out your plane's center of gravity. I am no expert for sure but have watched thousands of hours of youtube videos on successful and not-so-successful Rc plane builds. I am disabled and don't get out much, but I do like to try to help where I can. I really liked your design and ingenuity in building your plane. Hope my suggestions are helpful in giving you some ideas. I would also like to suggest you raise the engine above the rear of the fuselage and build a launch rail system that helps send your plane into flight. Raising the motor above the fuselage might save you from landing damage. I am sure you could print a design that would be aerodynamic while allowing the motor to be high enough to keep the prop off the ground meaning you could cut weight also by removing landing gear.

Great Job Michael. I was thinking maybe you can replace some of stressed members with carbon fiber sheets that be laser cut such as the fuselage spars.

Your build was awesome, don't get me wrong, but 1/4 ply seems way too thick, at this scale 1/8" would be fine and cut your flying weight considerably, hotglue is fast, but urethane glue is a lot lighter and you don't need as much, plus it expands and fills gaps.

Thank you for sharing on KZbin even though you obviously know what you're doing. You have my subscription.

great effort indeed. he really needs a hug when it crashed.

"Some part is still good! " Amazing optimistic, you are cool, man, fix it and make better with controlled camera. Great project!

Just to give my two cents worth, I think the cause of the failure is when you change the battery to a much heavier one leading to a nearly ( or tendency ) nose dive flight upon release or take off. The weight to thrust ratio should have been taken into consideration. But since you have proven yourself capable of building a diy drone, I believe you will be successful in your attempts or endeavours in the future. And so, I am looking forward to seeing your upcoming videos. Good luck.

I'm just glad you still have all your fingers.

Dyson had 5000+ prototypes before his vacuum cleaner was ready. Excellent work! 🤝👏👏👏👏

Enjoyed the video! Thanks for showing the build up to launch

[@joseph71345]

All that beautiful work oh my

[@thomasmcfarland5019]

Try building a launch rail, either electromagnetic or elastic and modify the belly of the drone to accommodate the launch rail. Take a look at the Zipline drone system and borrow some ideas from their experience.

Increase rigidity and cut weight by wrapping the body in a light fabric you've 3d printed a hexagonal pattern on to it.. Probably only need to be 1mm thick w/ 3mm edge. You can even design small reinforced areas as needed like extra ribs

Larger wing span . Catpult launcher instead of your arms . If it is still heavy use rocket for initial altitude and flight . Add a landing shoot. Best of luck cool content.

This is so illegal lol (at least in the US, trust me i've looked into big diy drones). Keep up the great work, and good luck dodging the FAA

[@calvinhenshaw2147]

thanks for sharing.. build the whole thing from 3D printing trying to learn that now.

If you want to make the plywood way stronger before you put it together, brush it with cyanoacrylate/super glue. It won't add any weight but it will make it incredibly strong.
