WhisperJetAmerica, brilliant 😂

Bwest6275, cheers buddy, much appreciated. Rotor Flex👍

Englishturbines, I had a laugh at the Rob comment as they aren’t easy on the wallet 😂

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👍

Hi_desert_rat, I totally agree. The sound of a big 2 stroke swinging a prop is amazing. If you enjoyed that let me know as we have bigger planes and some with smoke systems that I’ll do a video on if this type of video gets enough interest. Thanks for the comment….Rotor Flex 👍👍

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 👍👍

SaberKittyZero, thanks for the comment 👍

Englishturbines, we are luck that our flying site is well away from any houses so the noise isn’t an issue but the fun police have definitely spoiled it for a lot of sites. Yes both aircraft are ready built kits, I have an early wot 4 that was a scratch build but only seemed to be the earlier ones. Thanks for the comment….Rotor Flex👍

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

Brian, a keen eye for sure spotting the roof of the van 😂. Was a great day and nice to finally get the weather to do some real RC flying again….. Rotor Flex 👍

@@torquedude yes the weather has been brilliant! Unfortunately didn’t get out in at as I was painting garden walls and fences🤮but I am looking forward to the next spell of good weather, hopefully it won’t be too long away. Did you get up to the NW200 anytime this week? at least the weather was good for it for a change. Happy landings and keep her lite.👍👍👍👍👍

Rcplaytime, thanks man. They sound even better in person and the smell of the 2 stroke oil on the passes was amazing! Again thanks for the comment…Rotor Flex 👍

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 👍

Thanks for the honest feedback, it’s much appreciated. Music is something we all have personal taste in and is good to get some constructive criticism. I will try to make the sound tracks more universal in the future👍

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 🫡

FpvBerget, I have been wondering about that, have you had any issues with horizon at speed? Thanks for the comment….Rotor Flex 👍

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.

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 👍

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 👍

Aspir3, awesome design and great work! Thanks for uploading them and keep up the great work. Thanks for the comment and stay tuned buddy….Rotor Flex

Caroline_Tyler, that is an awesome speed!!! Mini Drak’s rock 👍👍👍

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 👍👍

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 😂👍👍👍👍👍

Just looking at it, you can feel the drag.

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👍

Michaelrothman4602, thanks for your comment. The buying options unfortunately do not come with video transmitter or radio receiver. You will need to purchase them separately. The dji goggles along with the 03 air unit is a great setup for your video and a lot of people are using the T16 radio for their rc controller. Hope this helps. Welcome to the channel…..Rotor Flex

KillerWhale806, cheers👍, don’t worry, I’m finding its limits and pushing beyond them 🚀. Thanks for the comment….Rotor Flex.

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

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.

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

Yes and when I say lots more speed I mean LOTS MORE SPEED! 🚀

Danpenry8899, yes coming from a hotliner background this is far from the fastest in my hanger but it all about the challenge of taking an airframe that is not designed to achieve this speed and improving time and time again. Good to talk to another speed enthusiast. Thanks for the comment and stay tuned for more speed runs….. Rotor Flex

lol, yea , lots of people say lots of things. Without OSD, you’re just someone making up stories…

@@user-otzlixr check out my main videos, all have osd 🫡

Thanks man, they are one cool plane ✌️

Love me some Daft Punk 👍✌️🤟

@@jordancoleman2402 I'd bet you aren't epileptic either. So of us have to be very careful because flashing lights or some loud beats can trigger an episode. Interesting enough, if it's lower volume it's less likely BUT if you turn the volume down, there goes hearing the narrator too

Bobjoatmon1993, thanks for your comment and I really appreciate the honest feedback. Moving forward as a creator I will definitely bare this in mind as I’d like the videos to be suitable for all my viewers. How did you find the video content minus the audio? I have just realised a new video on my channel th-cam.com/video/UYusSp1CB6M/w-d-xo.htmlsi=iejrBQYbut5CVnHf please check it out as I took into consideration the audio this time. The video is some of my other Rc flying adventures and not the AtomRc dolphin challenge as I’m waiting on another AtomRC airframe arriving to build a faster V3 version. Stay tuned for more. Thanks again for the feedback. Rotor Flex👍

@alcmann, I clean the surface I want to paint 2/3 times using isopropyl alcohol to remove the mold release agent. Make sure to change the cloth each time as the release agent sticks to the cloth. I also paint with Rustoleum aerosol as it takes well to the foam. Hope that helps and thanks for the comment….Rotor Flex
