KT's Martian Rover 6"

By KaityLynn on Sep 17, 2018

3 379 7

This is a 6" quad that I am building for longer range flying. The aircraft that I have now are designed for speed and efficiency was really a lower priority.

The first 5 flights were LOS sahakeout flight, but I was impressed that the cells after landing were still at 3.8 volts at 8 to 10 minutes!

My first FPV flight was 8 minutes and the next was 10! I will have to get used to this craft, very glidy! :)

Originally I was planning on having the pack slung under belly, but after a little adjusting the pack fit atop and feels better there.

Hi, did you fly it with bipale or tripale?? And with bipale, does it shake?? i have middle throttle oscillation with the bipale and i can't avoid them!!! Do you have a HD footage to see the flight....I'm really interested because 6" are so hard to tune......

thx!!! nice footage!!! no jello or throttle oscillations!!! so I have to reconsider my 6" (a lot of MTO !!!) Tripale or bipale??

KaityLynn Sep 21, 2018

I would try both and pick the one you feel is best. I have settled on the HQ 6x4.5 dual blade ones, which seem to stand up to my abuse :) I am going to try some tri-blade ones in 6" and see if they make any difference in efficiency.

What motors are your favorites?

I use Ummagwad 2150 KV motors in 5 S.

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..
