Now, which to choose....
I think the GT8 will have a bit more flight time with the same battery due to the bigger props and lower KV motors.

Interesting indeed! But these quite low kv?

But why no f4 fcb and why the extra stiff frame? :-(

The low KV is because its 2S,
The 9000kv GT7 is like the 18000kv tiny brushless on 1S

It is a bommer that there is no tiny brushless AIO with F4......

Stiff frame is for the harder crashes at home with this

The Beta 75x is 11000kv. The Happy Model Mobula 7 is 16000kv. Both 2s whoops.

Very interesting tinys. Let’s see how they do with those motors...

Price is in the highest range, but building quality looks great.

If you scroll down the product page and look at the visual package list, it looks like the given battery only has a balance lead.
And to charge the battery there seems to be an extra transfer wire cable that splits into a jst plug and balance lead. Strange.

Apparantly the frame is very week for the power and speed of this quad.

Donít read too much into kV. If the motor doesnít have the torque to spin the prop a low kV motor can actually spin faster at the top and slower at the bottom giving more top speed and better low speed control. Not necessarily the case here, but Iíd seriously expect the 16,000kV motors on 2s arenít coming close to spinning full speed under load. And if that isnít the case and the higher kV motors are spinning at full speed, then you just need a more aggressive prop to make up the difference.

If only the GT8 was set up for 110X motors, I'd be interested in the frame for some custom builds.

25mw VTX is crap, need at least 200mw.

For a whoop? How far do you expect to be going?

Right? If they did put 200mw in it they would complain about short flight times...

People tend to throw more power through a transmitter than improve their receivers/antennas.

What is up with Kingkong and their hate for betaflight OSD?! Looks like they have some sort of Janky OSD through the VTX which is better than nothing but it's not like you can fit an OSD chip on your FC/ESC board these days. Otherwise it will be nice to have some competition.
