ATILLA the Mountain Destroyer FR7

After starting with Micros...building my first 3"...and then getting into 5"...I realized I had to build a 7" too. That's how it works right? In all seriousness I sometimes get to fly in really huge open spaces, so i wanted to build something that could cover a little more ground. I didn't really realize I was diving into a deep new Long Range rabbit hole...but it helps that for now I've kept it pretty mellow and haven't gone past 2 miles out.

Issues with the build...I had a long week troubleshooting an arming issue which ended up being due to the Camera losing 5V upon arming because the LED/buzzer tailight was pulling too much voltage. I ended up just losing the tailight/buzzer and adding a ViFly free standing module. Other than that the tuning was a little tricky so still running 3.5.7, but everything went together great.

I started with a 3300mah 75C pyro pack. I flew that for maybe five cycles and then I picked up two new 5000mah 40c cnhl black packs, so now I have three packs total. I can really let loose with the 75C 3300mah Pyropack (love it, minus the price) but I found I had to stay pretty mellow on the throttle with the 5000's to avoid sagging (running 2408.5 1622kv). Either way glad to be able to fly a little longer!

Here's an edit from my first time out flying the 3 big packs. I love this thing! Definitely weird getting used to the 35 degree cam angle but it's so fast you need it. I also have a little cable to connect two batteries, so if I smash my 5" quad and still have 6S packs left over I just strap them to this thing and rip it!

Hey I'm running the taranis x9 lite too!! How did you mount the full sized crossfire to it? Any pictures? I'm considering if i should do that or not

Nice, yeah I love that thing, pretty compact but not controller style. I don't have any pics from my build but I followed the info from this page: http://racefpv.eu/blog/2018-05-30-crossfire-on-the-frsky-x-lite/ (Xlite is pretty much the same as X9 lite internally) Then I just velcroed the tx to the back! So slim the antenna fits under the handle. No issues since I soldered it up a few months ago.

So you're running the tx straight off the 18650 internal bats?? how has battery life been if your running 1-2wats though?

Wow, I fly all the time in Tujunga. searching up 7 inch motors, been flying mid range with my 5 inch and want to stretch my legs a bit more. Nice build and flying.

Nice! Yeah it's fun finding spots up there off the 2. I could probably do most of this with the 5", but the 7" has a cruising speed of 50-70mph and that's just awesome. The 5" feels like a toothpick compared to this thing! Find me on instagram @daverips_ if you ever want to fly, I'm always looking for people to fly with!

Cool I will. Just ran into a couple of other guys the other day along Tujunga. They say they fly along there a lot too.

Nice video man! I'm looking to build something similar. What kind of flight time do you usually get with the 5000 mah battery?

I get 8-10 minutes with the 5000mah, flying fast but I have to avoid hard punchouts or they sag quite a bit. With the 3300mah I get 5-8 minutes but can just absolutely go all out.

Im running BF 3.5.7 on a Brain Radix fc. Running RPM filtering. It flew fine on stock PIDS for cruising but I cranked the pids pretty high for acro stuff.

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..
