Long Range 6" Apex Cruiser

This build was conceptualised and brought to life mostly for the purpose of my 2022 Korea Trip to Jeju, where I felt the 5" simply wouldn't cut it for mid/long range mountain cruising, fighting strong winds and maintaining a good cruise speed. Some of the highlights of this 6" Apex are:

Crossfire Diversity Nano RX with rear TrueRC Bardpole SMA and front Immortal-T for extra coverage
Front and Rear LEDs, forms a triangle of light for easy LOS orientation in the air
BN220 GPS wired to 5V pad meant for RX on FC. GPS is hence powered by plugging in the USB port, allowing for a GPS fix using a powerbank before the quad is turned on. This makes it much easier to get a GPS fix
Conformal coated FPV camera with MG Chemicals 422C

i've got the same build but on 2208 motors and i m a bit dissapointed with the flight time.
Although i could fly 12 mins on a 5s 21700 on a standard 5" build. I can do only north of 9 mins 6s21700 on 6s.

Flight time is better for freestyle style though, would consider swapping to these motors.

moved everything on a 5.5 with 2505 motors and i get even less flight time that a 5" with a 2207

Werdna FPV Feb 13, 2023

That's interesting...

adv.andrei Feb 13, 2023

you need to stay very light on the throttle to get any range on it

Hey nice build! What flight times are you getting?

Werdna FPV Jun 22, 2022

Hey man I'm getting a solid 8 mins on a 1300mah 6S. Actually I've been too lazy so far to build some Li-Ion packs but I'm currently building a 3000mah 6S VTC6 pack and that one should be able to get 14-15 mins cruising.

Achaian Jun 23, 2022

nice!i have the same frame, but i am starting to consider turning it into a mid/long range as well. Would you change your motors for greater effciency, or do you think that you are at the sweet spot for power/efficiency?

Werdna FPV Jun 23, 2022

I think for 6 inch these motors are super efficient. You can run them on 4S, 5S and 6S with no problems, though 4S would need 6 inch triblades while 6S would need biblades and possibly a 90-95% motor output limit. Altogether, it is doubtless that 2505 is more efficient than 2207 or 2306

Awesome build and great video. Jeju Island is one of the few places I didn't get to go while I was stationed at Camp Case-Hovey in 2013.

Werdna FPV Jun 12, 2022

Thanks man! Wow that camp is quite close to DMZ. I also went there to visit haha

Build a 5" Long Range Drone - Transformer Ultralight

Jun 21, 2021

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
