The slow steady speed of this plane would be great for cinematic shots, its not as fast as I would like it to be but like a calm smooth flight, thanks for the review Oliver!
I feel like AtomRC does a pretty good job, but their motors seem to be undersized a lot of the time. Burnt up my Dolphin motor in just 3-4 flights. Moved to a 2806.5 and it's happy now. As for the Penguin, it's really a pretty neat plane.
Thanks for this great video Olivier. I ordered myself one as it looks to be pretty versatile and a good flyer. I'm a fan of AtomRCs built in FCs now and this looks like another winner!
Very versatile for sure, it flew in the mountains 2 days ago, with a 21700 liion had very good endurance, total distance of 47kms in about 30 minutes in rather strong wings, and was all fine !
Very nice video! Looking forward to also test this plane. My Dolphin's motor died - so I guess you're right with AtomRC using too large props on too small motors ;) greets and happy flying, Mario
Yep on the long run it pays to have motors slightly too big for the task :) On the swordfish too I found the 7" to be too much for the 2000kV 2306, I downsized to 6" and it goes just as fast and amps are like -25%

Nice review. A good tip configure motors to "spin inward" (9:24) vs. "spin outward" (the default), just in case. The Penguin seems to have much higher amp draw compared to the T1 Ranger, even after reduced by swapping motors. Seems to be ~1.5x higher. The Penguin does appear to have much more fuselage space for battery however.

Great review. Considering this but would prefer if someone would suggest something for free wing beginners. Something slower (maybe glider) but that runs inav with gps(RTH) and walksnail compatible would be great. Thanks
Great review, love all your vids! How much more speed do you think it gained by upgrading the motors as I have several of the same motors on hand, and were you able to use the existing ESC's?
Factory ESC are marked 30A, should be fine, they handled the 2206 with no issue, and now they are soldered to 2306. Top speed is 105km/h with the 2004, and 145km/h with these aging 2206, and with 2306 I think it should go about 160. But I don't expect much higher, the deep wing makes a lot of drag I think. Still, speed envelope from 25 to 150 is plenty
Hi Olivier, Would you recommend the Penguin as a first FPV Wing. I have some RC experience. Considering the Swordfish but I have less than Ideal takeoff/landing areas... no fields, heavily wooded, some cleared areas so it sounds the the Penguin would be the way to go! Thanks for all the videos! Very Inspiring.
For low altitude low speed stunts it make the plane a big heavier so that's not really better, but when going higher and cruising further, the added speed is a big plus. And I've already fitted new motors, T-motors Velox 2306 1750kV with 6", might fly these tonight
Salut Olivier, Il me tente bien, j'adore sa bouille. Dommage pour les moteurs d'origine. ( c'est vraiment la mode au petit moteur haut kv j'ai horreur de ça 😂 ) Je vais regarder ce que j'ai encore en stock en moteur 🤔
Son look au debut il est surprenant, c'est le raccord entre la queue et le reste qui est bizarre je trouve mais on s'y fait. Mais bon un avion FPV on a pas trop l'occasion de le regarder soi-même en vol :)) mais c'est sur qu'en l'air il n'a pas l'elegance d'un Swordfish ou d'un Dolphin.. Pour les moteurs, n'importe quelle taille 'quad 5" ' devrait faire l'affaire, de 2204 à 2306, 5", 6" en bipales... p'tet eviter les tripales, les ailes sont basses, ça va ripper à chaque atterro. Je li ai mis des 2306 kv1750 avec des 6", en 4S la vitesse de pointe ne va pas etre folle mais il devrait avoir un bon grip pour faire l'andouille près du sol
Question: I don't have the budget to get new engines for the Penguin, what props would you recomend with the stock motors? And with said props, do you think the speed and torque should be enough?
@@Olivier-C Sorry I do not understand, the plane came with 6'' 2.6 pitch props, which ones do you recommend? Sorry I do not understand very well prop names yet
@@Olivier-C Thank you for the info, one last question since you flew this thing probably everywhere, I'm stuck between the Penguin or the Dolphin, I want something that is easily portable, can fly for a decent time (20mins at least) and can more or less sustain moderate winds, probably for high altitude / long range. Which one would you recommend?
@@KanaBaradei they are portable the same, same size, but I feel like the penguin is more "al terrains", because it's easier to launch and also it needs a bit less space for landings, it can fly slower. For winds it's the same, very similar planes
Nice plane, great review! I think I'm going to buy one for my holiday location in south america. Had a Caipi2 there, but the hidden Dragons in a dark corner of Arduilot ate it. So replacement needed, and this looks fine! Any idea about expected flight time / range? Possible to do 10km out and back?
Hey Oliver, I've been looking for a dual tractor plane recently for proximity flying. Seems people like both the heewing T1 and the atomrc penguin. You seen to have experience with both, any advice on which to choose? Really appreciate it man!
hi! Get the penguin, no doubt it's a better plane. a lot more wing area, maybe like +60%, so a lot more payload abilities. Easily double the space inside. The T1 is a bit fragile, the parts for the tail are very thin plastics, for proximity flights the Penguin is a waaaay better option. In my Penguin I put some 4S21700 liions and it flies a long time, or I can put some small 4S-1300mAh so it's very light for stunts close the ground or below trees. The same 4S-1300 in the T1 is already the biggest it can carry. Just put some bigger motors in the Penguin, other than factory, these are undersized big time and struggles to spins 6"
@@Olivier-C Appreciate the thoughtful response! I had seen some people mention lately how great the HeeWing T1 was (I think even mentioning it was their favorite overall plane!), so your opinion really helps. The additional payload capacity will help with the LR stuff. I had also looked at the Swordfish or Flying Fish as alternatives, but in both cases the Penguin looked superior. Swordfish seemed like it was meant more for soaring, and the Flying Fish seemed like it was more of a lightweight beginner plane. Other dual tractors I've seen are just too big for my use case. Thanks again.
