hello wago did you test your platform out doors? how does it feel with wind? how do you thonk to mount the fpv thing??
am into buiding or trying to build my first endurance quad 360 kv 1755 4s or maybe 6s 5000 with auw of 2 kg I should get max 38 min theoratically but honestly prior to this iam watching a lot of those big quads like harder to be managed in flight vulrnable to wind and more susptible to criple not reliable as smaller frames all videos on you tube show a sooner or latter crash that's why i like to share my questioning to more experienced to avoid waste of things

Every single weekend that i had time to go outside for a flight, it has been rainy, so i did not test it outside.
Anyway, i mad the quad shown above just because i have been curious how far i can push it in terms of efficiency.

The tubes are just 0.3 mm wall thickness and the hover rpm is so slow that the rotational force can pull the rotor blades barely in a straight position when i over tighten the bolts just a little bit.

The motors (T-Motor MN4004-300KV) are rated 6s but since the quad is way over-propped i go with a 2s to maximum 4s lipo. With a 4s 450 mAh lipo it weights just 410 g and hovers for about 20 minutes. I guess if i hit a thermal it would never come down to earth.

So for practical use i would rather go with the build shown on the pics below. With the T-Motor MN4006-380KV that i used before i replaced them by Tarot 4008 Martin 330KV motors, it hovered for right below 80 minutes with a 6s2p VTC6 Li-Ion battery. The Tarot motors add 76g compared to the T-Motor 4006 but can efficiently lift a bigger battery, so it should easily make an hour even with the bigger motors.

80 minutes is seriously impressive.

I looked up the old thread. With bi-blades it has been 80:06 mins, with tri-blades 72:02 mins.

Some minutes ago i tried tri-blades on the Tarot motors - less vibrations, more grip, no noticeable bounce-back, nicer look.

I think they both look really cool.

Dragon link?


Do you use DragonLink? If so, which receiver pin out is soldered to a quadcopter flight controller?

No, i do not use DragonLink. There is just a SpekSat and a HM-10 bluetooth module connected.
