It's amazing what kind of geo and temperature range we cover in this little group of 3 here ;) 40c in winter? Brazil seems to be as broken as the rest of our globe... hope your fine Mario. And Bruce, starting up a fireplace and coffee sound quite good. I try to carpe diem as much as possible here in the summer since it will end eventually. Embrace the change, "life in the moment" is a bit too much now ;) Greets!

Finally got to test out this tune. As somebody who is on his first plane, I knew nothing about what kind of tune I should be going for, so having this one perform so well has really helped me gain perspective. So much less shaky!

Hi, nice to read this helped you! I just found those from another guy and tested them. looking forward to spring when I will get out this bird again (now in the winter if at all I fly my 7" and 10" LR drones). greets, Mario

[@alewarte]

Hey! :) thanks for sharing your build! JFYI: at 2:41 you launched with spinning propeller... A few week ago I did the same and seriously damaged my finger! And yes, many time before I hand't have any problem with it.... now only protective gloves and always have medical kit.

[@HermyH66]

Interesting find on the roll pids, might give that a try. I'm using the stock 7042 prop too (Gemfan Flash) with a T-motor AS2317 1400kv, it's a little bit heavier than your motor, but it helps to get the cg on the right spot as i'm using a 4s2p 6800mAh li-ion pack. It flies great with this setup and up to a hour.

[@Rcschim]

Wow, that's a heavy Battery but of course good flight time and good performance because of 2p

[@MCsCreations]

Thanks a bunch for all the tips, Mario! 😃 I don't know if those fans would make much difference, but there are esc fans that are strong as heck! And I already found them with 20x20mm, 25x25mm and 30.5x30.5mm mounting holes! Anyway, stay safe there with your family! 🖖😊

[@Rcschim]

25mm mounting holes would fit nice for the o3, thanks for the idea, I will also look for esc fans....

[@Finnv893]

​​​@@Rcschimneed a way for heat to get out and cool air to come in, no point circulating heated air, the added fan motor and battery are big sources of heat too. I would carve out the top cover and raise up the air unit till the fins are exposed to open air.

[@Rcschim]

@@Finnv893 agreed! I already thought about this as well. Will give it a try! passive cooling would still be preferred.

[@ImperialArmour]

I see in some builds the VTX is mounted externally for cooling.

[@ChainsawFPV]

Good info. I am in the process of building a Dolphin. Using a 3540 1260 KV with a 8x8 prop and a 60 amp ESC with the Matek F405WTE on INav. Should be a really fast combination.

[@davidwatkin1484]

I'm now on my 3rd Dolphin. This is such a well behaved airframe, I will always have one in the hangar....hopefully. I use a 2826 2200kv driving an 7.5x4.5 folding prop on 4S = 186kph😊

[@eitaje]

Excellent video! you gave good tips for the Dolphin. Also, thanks for mentioning me and my channel :-) I have additional tips, specifically about how to cool the O3 airunit. Instead of using an active element, such as fan, I like to use a passive mean, such as an larger nose air intake. I designed such nose and I will share the design in a following comment. Regarding the 6x4x3 prop with the 6S configuration, I do it all the time, and it give me a very decent speed and power. You just need to use the right ESC for it, as 35A ESC would not be capable of handling the required power. I use 45A esc. You should have the current draw in the flight controller log, so you can see how close are you to the limit of your esc, especially during takeoffs, where the current draw tend to be maximal. Lastly, my channel name is pronounced like the French word 'étage' 🙂

[@sarcasticfpv]

Hi, have i missed the upcoming comment as i am in the planning of building an atomrc dolphin with an o3 unit. That's why I am especially interested in the passive cooling

[@AerialWaviator]

Nice hanger/workbench update on how the Dolphin is holding up to lots of summer flying. It's looking stylish in the opening to this video. Great colour combo for spotting in the air when formation flying. On Thingiverse I did see a "wingtip winglets" 3d-print design listed. There are also 3d printed versions of the canopy, that could be modified to provide better O3 cooling. Didn't spot any with a NACA air inlet. With cooling, the outlet is as important, or more so than inlet ... so air can escape. (also larger outlet cross section avoids pressure buildup, which could mess with FC pressure sensor for altitude). The ATOMRC Penguin has FPV nose option witch offers good VTx cooling. Would have been a smart design decision if ATOMRC made such a FPV nose interchangeable between the Dolphin, the Swordfish and the Penguin. Have been wondering if such is the case? A possible option, even if need to design an adaptor/spacer between fuselage and the FPV nose.

[@Rcschim]

Thanks man! I had more time to use my zhiyun m3 gimbal on the Sony cam for the intro. I should get the penguin eventually, will see how good the fpv cooling nose works there. Maybe I can 3d print the penguin nose for the Dolphin?

[@fpvwing]

NACA (ish) intake fitted. I removed the ESC grill on this one. ESC is 80A and deep internal :) kzbin.info/www/bejne/j3eZfoRtirGlqpY

[@sparkequinox]

Yup, 3 weeks ago burnt my second dolphin on its maiden. Did autolaunch and by the time in leveled out 8 seconds later I had no thrust and took me a few seconds to realise what happened.

[@eparustefan]

After i added the air vents in the back cover the overheat warnings are no more, the airflow removes the hot air from inside, i also added a 4 cm heatsing with thermal paste and 2 icecream sticks(1cm long) hotglued at 45 degrees angle near hitsink to better hit the heatsink with cool Air. I also removed the wooden GoPro holder for better airflow entering the nose.

[@dronepilot260rc]

I use Emax ECO II 2807 1300kv and you can run 4-6s no issues or worrying about cooking the motor

[@pofotiouzois]

does it have enough power with 4s?

[@icemanf6417]

Wow very smooth!

[@daviddavids2884]

some late information a correctly spec'd electric prop is QUIET. therefore, if your prop is noisy it's the WRONG prop. a stiff EP prop should be used.

[@breckfreeride]

Sad i went with a quad motor... burn out on high throttle runns will kill it... gotta keep the amps low except for 10 sec runs.

[@eparustefan]

How is the range with the dji o3 antenna mounted horizontal ? Mine now is sitting inside the plane vertical but at 2 km away i had some stutter frames, the bitrate was ok just the images stuttered a little bit i im considering taking it outside. Im scared about the mount like you have the lateral side of the plane where the antenna is installed has less signal strength.

[@EnglishTurbines]

My Walksnail VTX will be mounted outside in the airflow...Its half the thickness and weight of the 03 I guess too. That big sink and now a fan too?...Put it out in the fresh airstream, end of problem. All that heating will be shortening its service life....🤔😳😳😏🇬🇧

[@Rcschim]

I guess mounting it in a height where just the heat sink is on the outside would be best...

[@Rcschim]

In the nose of the penguin the o3 should be cooled well, but it still gets quite hot

[@EnglishTurbines]

@@Rcschim I guess that would work too. It rather depends on how effective your thermal transfer paste is IMO.....🤔🤔🤔😳😏🇬🇧

[@EBPlusC200]

@Rcschim, did you end up adding a fan to cool down the air unit in your Dolphin? I copied your set up (parts) because i like how you presented your system set up. It makes it easy for a noobie like to confidently get into planes. Been flying drone for years and i want to start rc plane. Practicing on simulator and slowly buying the parts for a new build. thank you.

[@Rcschim]

I bought some, but haven't installed them yet. Cut a bigger hole in the nose to have more air intake there. Added a little "ramp" infront of my foam seat where the O3 "sits" to have the airflow better. Guess my air scoop sitting behind the (turbulent air) O3 cam isn't great to suck in air there - so the nose with a bigger hole was better I guess. will see in hot summer temps if I need to change this. added fan has the bonus of worry free preparation before launch (for exempl if you wait for a friend to be ready). with active fan it will not overheat while just sitting there. Other method: a little switch to turn on O3 in the last second before starting...

[@EBPlusC200]

@@Rcschim thank you for the update and tips on your build. I've been watching lots of Inav videos and how folks build their rc planes. This is all to me and i will need lots of help from time to time. At this point I'm waiting for the parts and still deciding if i should put together a LI-On battery pack or just go with the tradional LIPO.

[@Rcschim]

I used 18650 liIon packs on the dolphin, with 3000mah, that’s ok for cruising and long flight, but for flying a bit faster and more confident, a 2500mah 4s lipo felt better (more punch).

[@sparkequinox]

I don't suppose you have the autolaunch settings you are using in any video? I just changed to the F90 and crashed on autolaunch. I think my settings are too high and overtorqued it. Yours just flew away practically with zero roll, very impressive.

[@Rcschim]

set nav_fw_launch_velocity = 300 set nav_fw_launch_accel = 1863 set nav_fw_launch_max_angle = 90 set nav_fw_launch_detect_time = 40 set nav_fw_launch_idle_motor_delay = 1000 set nav_fw_launch_motor_delay = 100 set nav_fw_launch_spinup_time = 100 set nav_fw_launch_end_time = 2000 set nav_fw_launch_min_time = 0 set nav_fw_launch_timeout = 15000 set nav_fw_launch_max_altitude = 0 set nav_fw_launch_climb_angle = 25 set nav_fw_launch_manual_throttle = OFF set nav_fw_launch_abort_deadband = 100 set nav_fw_launch_thr = 1850 set nav_fw_launch_idle_thr = 1400 set nav_fw_launch_thr = 1700 set nav_fw_launch_idle_thr = 1000 set nav_fw_launch_thr = 1700 set nav_fw_launch_idle_thr = 1000

[@Rcschim]

below my current settings. I prefer to have it spin up the motors to 40% idle throttle 1sec after I armed and moved THR stick to ~ 50%

[@sparkequinox]

@@Rcschim Absolute gentleman, thank you so much. From first glance those are actual very similar to mine, I also have it spin up before throw. I did have my climb angle set to 30, and perhaps together with slightly bad throw it just rolled over. I will try these exact ones though in the coming days and report back. Waiting on the glue to dry :) I just noticed, are these not the same 3 settings? set nav_fw_launch_thr = 1850 set nav_fw_launch_idle_thr = 1400 set nav_fw_launch_thr = 1700 set nav_fw_launch_idle_thr = 1000 set nav_fw_launch_thr = 1700 set nav_fw_launch_idle_thr = 1000 I ask because from memory I think I had idle at 1400 then spun to 1800, which I am guessing was why I over torqued. Just wanting to check your idle/launch value.

[@Rcschim]

Sorry about the repeated setttings, those are the values from 3different battery profiles, the first is the one i use. (I've filtered the nav settings in excel...) One thought tho: please make sure your stability settings are correct (if you are in angle mode, double check that the fc corrects in the correct direction. You can make -values in the mixer and invert servos and every thing looks correct in acro, but when the plane wants to stabilize it flips over....

[@sparkequinox]

@@Rcschim I usually take off in Horizon mode. I think you mean just check if I hold the plane to check if the flight surfaces move in the correct way to oppose the roll? I will double check it next time I power up, but I assume since I have flown this plane over 25 times at the point it is good. Though I can never rule out an accidental parameter change. Likely just a terrible throw (too high) and the climb angle just a little too much that it stalled out.

Hi, recently, I changed the Dolphin motor from an Emax EcoII 2400kv to a T-Motor F90 1500Kv using the same 7042prop and launch settings. Upon Autolaunch the plane somewhat stalled and crashed in both my attempts. Could you please suggest what settings I should change in order to launch the plane successfully?

[@pilwar]

Try this: set nav_fw_launch_velocity = 300 set nav_fw_launch_accel = 1900 set nav_fw_launch_max_angle = 180 set nav_fw_launch_detect_time = 40 set nav_fw_launch_idle_motor_delay = 0 set nav_fw_launch_motor_delay = 100 set nav_fw_launch_spinup_time = 100 set nav_fw_launch_end_time = 4000 set nav_fw_launch_min_time = 0 set nav_fw_launch_timeout = 8000 set nav_fw_launch_max_altitude = 12500 set nav_fw_launch_climb_angle = 30 set nav_fw_launch_manual_throttle = OFF set nav_fw_launch_abort_deadband = 100 *When you arm the autolaunch propeller will star spinnig on idle but after launch will increase the RPM* try to throw it forward 20 degrees nose up, avoid higher up from there.

[@Rcschim]

Pilwar has some good tips already, here are my current settings: set nav_fw_launch_thr = 1850 set nav_fw_launch_idle_thr = 1400 set nav_fw_launch_max_angle = 90 set nav_fw_launch_idle_motor_delay = 1000 set nav_fw_launch_motor_delay = 100 set nav_fw_launch_end_time = 2000 set nav_fw_launch_timeout = 15000 set nav_fw_launch_climb_angle = 25 set nav_fw_allow_manual_thr_increase = ON So the above settings that matter are: launch_thr - this is set to 85% - not 100% idle_thr is set to 40% - this helps you to see when autolaunch is enabled - also it helps you to get a straigth throw with some motor support already. Watch for your fingers tho! Dont throw too steep - it will climb on it's own! throw it horizontally or slight up - so it can get to enough speed quick. DONT touch AILERON or ELEV. Stick during launch - this will ABORT your autolaunch and then you're in charge suddenly (maybe that's what happend to you?) Make sure your have the correct CG and not too much weight! Heavy Dolphins are difficult to launch. I mostly fly with 2600mah 4cell Lipos. good luck on your next flights - my autolaunches on all planes are such a nice way to start a flight - never have issues! this now made me want to fly this afternoon ;) Greets, Mario

[@Rcschim]

I bought a little PC fan but never installed it, not been flying the Wing much in the last few months. More quads, sorry... But with decent airflow and I guess 2.7k instead of 4k it worked reliable. Just increased the hole in the nose and led the air directly to the air unit.

@@erlandfpv if you use 4cell you can stay with the 7x4.2 prop that came wit the plane.
