So this is what 3 days of solid research has bought me too. Im going for a long range/freestyle type quad. I understand this list will be missing a few bits as Im still a newb and the receiver and transmitter side of things, confuses me!
So here, go's, please can people recommend any replacements I should make and also add parts Ive missed.
Frame - Supafly Flipmode 6"
Motors - T-Motor F40 1600KV
Props - 6x3x3
Controller - FrSky Q X7
FC and ESC - Supafly's Aikon flight stack
VTX - VTX Immersion Transmitter
Receiver - TBS Crossfire NANO
Antenna - Foxeer lollipoo v3
Camera - Foxerr pred mini v4
Battery - Any 6S 4000Mha
Goggles - Fatshark Pred v2
Looks like a decent list, just a couple things I'd change up. When you say the Immersion VTX, I'm assuming you mean the Tramp. I'd change that to a TBS Unify Pro, smaller size and higher output.
As for the battery well that's about twice as big as is is even practical. In LR, there's a fine line where the weight of the battery causes shorter flight times. The largest my 7" Falcon MR can take is 2200 mah, any larger then the flight times start to decrease. The sweet spot on a 6" rig is usually around 1800-2000mah.
As for the TBS Nano , that's about as good as it gets as far as a 915MHz receiver goes but you will need the Crossfire module to go on your QX7 transmitter
That lipo would probably fit but may be a tight fit for the HD camera depending on your setup, best thing to do would be to contact SupaflyFPV directly for support. As for the Nano VTX, I wouldn't recommend it for any long range as it's max output is only 400mW and it only has a 3-13v input so you'd need a regulator to supply power. I'd suggest the normal Unify Pro which is 800mW and can be powered by full vbat https://www.team-blacksheep.com/products/prod:unify_pro_hv_sma
