AtomRC Dolphin -6S- FASTEST ON YOUTUBE (Part 3)
HTML-код
- Опубликовано: 5 май 2024
- The challenge continues against "Jeff does this..." as he has claimed to have match my speed of 137MPH. In this video i decided to match Jeff's upgrades by using a new higher C rating battery as my original battery used for the previous speed runs is old ( 4 years old ) and getting puffy. I tested a couple of well known branded batteries after breaking them in by taking them through a series of charge/discharge cycles, each time increasing the discharge amps. The winning battery was used for the speed run and the results are impressive but also devastating as the airframe once again let me down. Please like and subscribe to the channel and also leave a comment if you would like to see more of this sort of thing. I will be building a new V3 dolphin ensuring the airframe can cope with the high speed as i had a few ideas on how to further improve the aerodynamics and was going to carry out the mods next video.

Nice Job! This is just my opinion but I will say that for a speed record to count, the plane should stay together and not yard sale it's self into the ground. But, this is a street fight so there are no rules and anything goes. I am working on my Swordfish right now but soon my LiPo battery will be in and I am betting you are going to loose the crown again! Plus I am going to land my plane in one piece like a man.
Jeff, said like a true sports man! I look forward to the future challenge and I wish you luck on your next attempt, you’ll need it 🫡
😂😂😂😂😂 I'm in tears😂😂😂😂
My mate crashed a wing before due to wing flex and the fact that the servos are underneath. It’s harder for them to push to bring the elevons up and the servo rods bend. I will fit my servos on my dolphin ontop and strengthen the elevons. It looks like you lost the hatches in yours, you can see them fly off just before it crashes.
Nice run!! Sorry for your loss. Looking forward to V3! 🍿🍿🍿
Hey DINSTAAR-FPV thanks for the comment. No worries losing the V2 today as It means that you get to look forward to the V3. I had plans to make major aerodynamic mods to the v2 after another speed run test so you will see these modifications straight away on the V3. Again thanks for following along…..Rotor Flex
I am happy to report that all electronics have survived the 142MPH crash and AtomRC have posted my new Dolphin airframe. Stay tuned for the new improved, faster version 3! 🚀
RIP V2.
I've seen your friendly competition with Jeff from the US, and I've just built my dolphin, and it's as slippery as a real doplhin!!!. ;)
NB: I'm from Wales... a fellow celt. :D
DugDiamond1, welcome to the channel my friend. Thanks for the comment and I love that you’ve built a dolphin, fantastic airframe and fly great straight out of the box. Stay tuned for my V3 version as you’ll love the aerodynamic modifications coming! Thanks again….Rotor Flex.
Poor Jeff, hes still got no idea....His butchered Dolphin is a supreme example of added drag....🤔🤔😏😏🇬🇧
Failure in mid-flight is an automatic DQ. The rivalry is still alive. My dolphin ejected it's motor once and floated for over a half mile before landing safe. It died 2 flights later much like this one, nose first!
I like the fact you are staying true to a single engine design. It is more accurate to the dolphin design imho.
Bwest6275, cheers buddy, much appreciated. Rotor Flex👍
I love the rivalry. keep pushing it. I want to see what's possible!!
KillerWhale806, cheers👍, don’t worry, I’m finding its limits and pushing beyond them 🚀. Thanks for the comment….Rotor Flex.
what flew off the plane at 142mph? cover the next Dolphin in gloss auto vinyl wrap. super slick, light and strong!!. my AtomRC Mobula is super strong and stiff after wrapping.. Loved the video series and the soundtrack!
Jarestaniland9117, the part that flew of the plane mid roll was the rear compartment hatch. The funny thing is that the hatch was from my previous build and had survived the previous crash. The running joke at the field after the crash was that the hatch knew what was coming ( big crash ) and decided to eject before impact 😂. Thanks for the comment and welcome to the channel 👍
@@torquedude that hatch flying off could of caused the crash. I had it before. I think the wind pressure can mess with the barometer or something els on the fc.
I'm hooked now, already ordered a 6s ESC and battery for the Mobula.. AtomRC gonna luv you 😉
@@jaredstaniland9117 excellent, if you need any help I can get you to 137 safely but any speed after that is experimental from there on😂
@@ttucker2073 yes I was thinking that also but then I realised that the death roll started before the hatch came off so that has me thinking wing wobble due to lack of strength. My V3 will be able to stand the extra speed with my new mods ideas. Just waiting on the delivery man arriving so I can get started👍
I would say your camera and transmitter sticking out on the nose is 10 to 15+ mph loss... Power doesn't give you that much more speed.. getting rid of drag does
Lots more speed in the pipeline for V3!
Yes and when I say lots more speed I mean LOTS MORE SPEED! 🚀
Is the music more important than what you were saying?
Fun back and forth. Ending in pieces though not sure if that counts. Hopefully you'll get a survivor.
This a fun contest! The Dolphin is not really the best for speed, I love them and have two myself....but for raw speed a Mini Drak is hard to beat - Mine did >160mph in level flight, mind you it did pull 137 Amp on the 4S battery 😁
Caroline_Tyler, that is an awesome speed!!! Mini Drak’s rock 👍👍👍
Hiya big fella (I) think it’s time to laminate your next high speed model, it will make the foam stronger and more efficient at high speeds. There’s plenty of videos on the tube to watch to get some good tips, painless 360 has a video covering how to cover. Keep up the good work and the pressure on poor old Jeff. 👍👍👍👍👍
Hey Brian, yes the wings will need reinforcing on the new one as it will be travelling a fair bit faster than the last one! Still deciding if I’ll skin the wing or cover it. Cheers for the comment Brian and I hope your still flying these days👍
@@torquedude Yes was out last Thursday when the wife was getting her hair done 🤮 Just went to New Mossley with the Avata to have a look at the latest new build, it’s a place now where there’s lots of building taking place which is good to see. Can’t wait for the next chapter between rotor - flex and Jeff 😂👍👍👍👍👍
Something came off the model well before it went in. Looked like the main hatch....Id tape them all shut next time....🤔😏😀🇬🇧
Hey EnglishTurbines, well spotted my friend. Yes I think taping them shut on the V3 is a great idea. I have uploaded a new video of yesterdays flying at the field with our big petrol planes, check it out and let me know if you’d like to see more of that type of content as I’m trying to grow the channel but would like some advice from my subs👍 thanks for the comment and stay tuned for more…. Rotor Flex
Ouch.. nice crater... And you're probably right about Wing flex cuz foam likes to flap when it gets going fast...
Danpenry8899, welcome to the channel 👍. Yes I found that the elevons in the previous version had to much flex that lead to a similar crash so when I built this one I carbon fibre skinned them but in hindsight I should have done the whole wing. Stay tuned for my version 3 build where I’m going to make some serious aerodynamic modifications. Thanks for the comment….. Rotor Flex.
@@torquedude well I love your videos so I hope to see more .. open to see you break the 150 mark
Ohh boy!!!!!! You just lost the Crown! I beat you by over 30MPH! I also landed the Plane!!!!! I will try to have the video posted tomorrow.
Jeffdoesthis, now you’re taking and making it a bit more of a challenge as we can now start getting serious ! I’ll gladly hand the crown over but just be aware that my V3 Dolphin will be built soon and when you see this peace of art that crown better be well polished and ready to hand back! Epic achievement by the way and good work…. Rotor Flex👍
The materials have limits.
Epic, do you have a link for those leds
MrBEEFCAKE26, thanks for the comment. If you enjoyed that wait until you see my newest video coming shortly with my much faster version 3 build of the dolphin. Here’s a link to the LEDs I’ve used in my builds betafpv.com/products/pavo-series-cob-led-strip . Cheers…..Rotorflex
Can't wait pal new sub, hear
@@MrBEEFCAKE26 your sub is much appreciated buddy. You haven’t long to wait to the new video, if the weather is flyable at the weekend you’ll hopefully see an awesome speed run!👍
Couldn't really hear you over the music.
HelloDonkey9, unfortunately I don’t do voice overs on my videos as not everyone wants to hear the Irish accent. It’s narrated only. Stay tuned for the v3 faster version. Welcome to the channel 👍👍
Hi,
Can you share the .stl file or the 3D file for the motor mount used on this model? The part that goes right behind the aluminum plate attached to and holding the motor.
Thank you
Johnd1841, yes certainly no problem. I have spend a fair bit of time looking at different mounts but this one ticked all the boxes for me. www.thingiverse.com/thing:5147947
Awesome, thank you so much!! It's a great and aerodynamic mount, allows clean airflow to get to the motor. Your Dolphin looks amazing, too bad it had the mishap. Hopefully you will rebuild it soon. That's a Five33 Champion edition 2207 2070kV motor, isn't it? High kV for 6S. What size is your prop? Looks like a really nice motor for the task. Amazing speed achievement, keep up the great work. Just unbelievable.
@@johnd1841 yes it’s the five33 champion edition. It’s definitely high kv for 6s but it’s proped on a 5x5 so not loading the motor up to much. I’m waiting on delivery of another dolphin air frame so the build will resume soon. Again thanks for the comment and happy to help a fellow rc enthusiast out….Rotor Flex 👍👍
I should join this..ive a beefy motor running a 7x6, a 7x10 to try, a few mods and now running at 2300mah 6s since my 1550 coudlnt output the 70amps for long enough..
Hey from the quad FPV side.
If you solve stability issues, then why not try even bigger motors like 2808 1500kv on 8S
Chrisbee5481, welcome to the channel. Yes 8s would be much faster but I am trying to improve on the current setup via aerodynamics. The v3 will be using the same motor/battery setup but trust me when I say it will be much faster. Maybe the final video I could do a motor upgrade just to see what it’s capable of…..Rotor Flex 👍
Are you thinking it torque rolled or elevon/servo failure? We need NTSB investigation lol
TacticalFPV, I had upgraded the servos and reinforced the control surfaces by carbon fibre skinning them so the only thing left is wing flex. The v3 I am building will have the wings fully reinforced, carbon fibre skinned control surfaces and height torque servos for good measures. The V3 dolphin will definitely handle the extra speed this time. I’m also making some major aerodynamic mods to the V3 to massively increase the top end speed so the max speed figures should be interesting. Stay tuned buddy as you don’t want to miss this one ….Rotor Flex 👍
@@torquedude wow, yea I just remembered the build video for this plane, that carbon fiber skin should have been enough, so it would seem. I’m building a dolphin now that I hope to do high speed runs as well and your crashes have helped me a lot, thank you for your sacrifice! Looking forward to V3!
@@tacticalFPV that’s fantastic that your building a high speed dolphin. I will be uploading the build of the V3 so you can try some of my new aerodynamic modifications if you want to get the most out of it. Any questions you have during your built just drop me a message, I’d be happy to help 👍
Sorry, but a speed record is more than a short moment flashing a number in OSD while diving.
Hold that Speed about 5 sek in a level flight and repeat in the opposite direction, than I will be impressed.
GramGrindt, I 100% get what you are saying from a land record but being a pilot myself I have to disagree as the only true way of recording an aircraft’s speed is via airspeed. I have a digital airspeed sensor so I’ll add it to the next build. The 5sec hold at a constant speed is not achievable with a lipo battery as the amp draw will pull the volts down when hitting the max C draw. A piston engine or turbine can sustain a much longer continuous speed as they do not rely on a spiking energy source. Stay tuned as the version 3 dolphin will be a record smasher!
@@torquedude I am looking forward to see your v3.
I know about the problems with setting a speed record. But when the Voltage drops to far in a 5sek full throttle, you need a bigger Battery.
For an official guiness speed record for RC Planes a level flight about 100m in both directions is needet. Under this criterion its mandatory to see the top speed at least for 1sek in the OSD. For accelleration without dive you Dolphin must survive ~5 Sek full throttle.
In my optinion this is a good starting point for your battle with Jeff does this. Good luck.
try one of the tatu 1300mah packs, they'll do 150C and they *hammer*
Shanemshort, yes the tatu packs are fantastic. 150c is a hammer for sure. Thanks for the comment and ideas. Rotor Flex 👍
the audio is awful and why the fork you using 75c batteries when there are 150c for the basically the same price?! Cool af though
Point taken re the audio as there has been quite a bit of feedback, I’ll make sure to change it up a little on the V3 build. The 75c battery is one I had laying around but I have sense upgraded to a much higher C rating. Thanks for the comment and the honest feedback is much appreciated. Check out my latest ‘HUGE XL RC planes’ video, the audio is hopefully more to your liking. Rotor Flex 👍
Im pretty sure the issue is horizon mode... Try acro next time.
FpvBerget, I have been wondering about that, have you had any issues with horizon at speed? Thanks for the comment….Rotor Flex 👍
Please lose the music!? Awesome video if you mute the sound...
