That's the actual weight of the unit. The entire calc is based on the actual weight of each component, not estimates. Read carefully at the AUW at the result area. AUW is 4671g (or 164.8 oz)

Thanks for pointing that out. The 6s system with low KV is truly much more efficient

Ecalc is way off with some motors. I am building a Vulcan 900 hex and picked out 3515 400kv motors because ecalc was giving me a flight time of 20+ minutes without camera. The dealer I purchased from told me that they got better flight time from newer 4014 400kv motors, but ecalc says the same hex with that motor is only 13.7 flight time with no load other than the battery and required equipment to fly.

Actual flight time with 80% of the 10400 6S battery is just over 22 minutes. AUW 4180 grams.

As long as you put in all the parameter with the actual value, and not using their default numbers, you'll get quite accurate result.

And the gimbal is made of aerogel? Air? The FC is virtual? Gps? All of them weight and you have to add it to the frame weight. What camera?? I am interested also in this frame but I dont see how they are managing vibration to the gimbal... so youll have to build one or wait till they design it. Also with this frame you have to use 2 batts or you will have an unbalanced frame. I liked the Mantis frame approach more. A single carbon plate in the middle above IMU and near COG. I was expecting more from this frame ;( That front plug what is is for? i would never leave my power unsoldered... if thats for power distribution I will not feel safe byletting my power just plugged. Hope someone can give details about it..
I rather have unobstructed forward view than foldable design.

Foldable is just another link that could have problems as the previous folding tarot had.

You can indeed mount a single battery tray in the middle It even shows that as a configuration option on Tarot's website.

Yea, as designed, it only use 1 battery. Using 2 batteries is just my personal preference.

Look at my last Hexa. It was a Talon v1 650. You can see my build log here and can expect similar detail in this one.

The Talon v1 650 has a very small footprint:


And eventually I modified it to become this:



So that I can use the cheapest and lowest C rating LiPo, and a very balance layout.

Now, go try to find me some cheap 11600 mAh or 16000 mAh 6s LiPo. On the other hand, I'm sure I can easily find the 5800 or 8000 mAh ones in stock.

Regarding the AUW with the gimbal and camera all installed, I wouldn't worry too much about it. By my calculation, this build can handle about 9kg AUW and with 8 min hover time. Plenty of room to play with. As I build it along, you'll see. That's what these Build-Log thread is all about, isn't it?

Just Ordered the T810 at Infinity Hobby (Superb service!) I got the Tarot 320KV motors and some 15" DJI props. I will be flashing the ESCīs myself with BL-heli firmware.
Cant wait for it to arrive. I havent ordered Lipoīs yet, but i think it will be 2X5000Mah Nanotechīs.

Oh nice! Would be great to compare performance/flight time on different motors and props, and ESC!
