Originally built to see how 4 & 5S Lithium Ion packs would turn 8" bi-blades on BH 2806.5 1700Kv, I was having a hard time with vibrations so I started flying 7" tri-blades.

I've flown this build on several DIY LiIon packs:

I love these motors on pretty much any cell / prop combo, but 5S & 6S LiIon and LiPo on 7" bi or tri-blade seem to be an excellent balance of performance and endurance.

The iFlight XL8 frame is my first iFlight purchase. I picked it up from amazon, along with their 3D printed Session mount. The print came with an ND filter, which was a pleasant surprise. The frame carbon fit and finish seems to be pretty decent. Fantastic for the price. I ended up removing the session mount after about a week when I finally got around to buying a Hero 7 Black. Long range cruising videos are my favorite thing on youtube, so I'm hoping to make some of my own. Here's the first "pretty" test flights with the XL8 and Hero 7:

Here's some night derping on 5S LiPo w/ 7" Triblades (Gemfan I think):

Here's my more recent 6km / 3.8 mile (max distance LoS) flight on HQ bi-blades (old greenies). 7.2km / 4.5 miles following the bend of the shore makes this a 9 mile round trip for my new 6S LiIon:

What cells would you recommend the most out of the bunch? That long range test looks really interesting!

Depends on what you're after. These 21700 are pretty damn nice though. Going to try some molicel next.

What is the best bang for your back then?

The Liitokala Lii-50 are a pretty crazy value. Huge capacity and decent amps. I figured they would die off quickly or fail but I've got loads of flights out of my big fat 4S1P packs.

Watching the vids with my son - "no he's GOTTA turn back now!" Just amazing the range you're getting!

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..

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..
