170kph FPV Mountain Dives & Scenery Surfing | AtomRC DolphinPro fixed wing

 !Please watch with 60fps (maybe set your TV to this instead of 50hz), so it's as smooth as intended!

Had some amazing flights with this bird. Not the most efficient one (in fact about 25% less efficient than its predecessor), but avg speed of 100 kph let's you zip around in the scenery, and full throttle gives me 170kph and a bit better handling in gusty conditions (important in the mountains).

I had to get used to this plane. It's dialed in better now, quite reliable - autolaunches always work, plenty of power even for bad throws (see settings in my initial review or directly here)

INAV 8 still gives me pitch oscillations (or "dolphining" up and down with the nose on cruise mode or RTH modes). From OliverC:
- CG ahead of the factory marks (3-5mm), and 3 mm "reflex" on Ailerons (3mm up trim, supposed to fixe the pitch oscillations)
- I use a DELTA mix with AILERONS (as on the old Dolphin) and just mix in 20-30% of elevator on the VTail - this flies better than stock config with traditional elevator

Landings: can be a bit tricky... I found that "flaring" it (up elevator and 0 throttle) to slow it down makes it land like a stone. So a bit of throttle and not to much pull on elev.

Also might install a "fin" on the bottom to protect the prop on landings (don't want to use folding prop). So far the stock props holds up nice.

Stats: These were 12 flights, 1h 52 mins in the air, 22 Ah, 192 km distance covered

I mostly fly 2x 1300 mah 6cell pacs in parallel (lipos from my 5" drones, 10 mins) and also 21700 based 6cell LiIon with 5Ah for longer flighttimes (around 13mins). You have good ammount of space in cockpit to move around batteries for CG. Long Packs work best.

I still run DJI O3 on this plane, ND16 Filter, Gyroflow Plugin in Premiere with stock settings, (Rocksteady off in O3!)

The Moment That Sold Me on the Creality OTTER lite!

 

From desk tests to a full garage moment – see how the Creality Otter Lite 3D scanner delivers stunning results, even wirelessly! https://www.geekbuying.com/go/9xzkghQz (affiliate link!) 🛒

In this review, I put the Otter Lite through multiple real-world tests to see how good it really performs. Thanks to the WiFi bridge, scanning directly to my laptop was super fast and cable-free – the perfect combo of convenience and performance (but not all PCs have wifi! and the laptop should be fast enough!) Whether you’re into 3D printing, product design, or just love cool tech, this scanner offers pro-level results at a price that’s hard to beat.

DolphinPro Dives - Path of a Hero

 Not been flying a lot in summer.  Either TOO hot or rainy - no inbetween. Also many windy days. And even this one here was forecasted as low winds - but up there on the ridgeline - Gyroflow really had to work hard to stabilize footage :)  

Super happy with my setup now - INAV 8, 2x 6S 1300mah packs. Not ultra long flighttimes - but good punch and sporty flying.

And if I want more time in the air, I use 6S 5000mah LiIon.
