Updated acrobrat to caddx vista.. running gnb 850 4s and 6s xt60's.. crossfire nano with immortal V setup.

Update (02/27/2020), Too heavy with xt60 and 850mah 4s/6s, switched to xt30 650mah 4s (-47.8 grams/15%)

update.. 05/24/2020, swapped esc to aikon and flight controller to matek f722 mini.

update... 08/14/2020, Axii antenna swap, moved the cap to the batt connect. Was getting a weird vibration around mid throttle (sounded like vibrating change, idk) After dampening questionable wires.. it got a lot better but sometimes I can still hear some randomness. Could be tripping, flies fine on 4s. On 6s it completely freaks out, maybe it's the FC or ESC, my iflight stacks didn't have this issue.

thank you so much for posting your rates. I'm new to tuning, and this helped alot. i'm about to go fly a pack and see how it works out. ty again!

Hope it helps, let me know how it goes!

i'm still struggling. hoping to get you tomorrow for more flights. seems very jittery/erratic. lots of jello on my cam (runcam hybrid). not using dji, so half your build is different than mine. probably impacts much of the tune

i threw the vista in Tommy's orginal frame and all seems well. currently running 1408 motors, it feels sluggish and a bit heavy so its not very agile. Its good for cinematic and exploring but i want it to fly more like my 5inch. Do you think that the 1500 series motors would help this much? what props have you found best for your build?

I have tried HQ 2.9 x 2.9 x 4 and the gemfan 3052, I think the gemfans have more thrust but running 6s makes a big difference. Not sure if there are 1408 motors that run 6s but the 1507 flat rats or tmotors at 2700kv are legit with a 650mah 6s.

Hows it fly? I just built a duo with the t motor 1507s, and am having trouble tuning it. Did you have to tune it much?

Waffles   Mar 04, 2020 

I like the way it flies now that it's lighter and slightly slower rates (started 1.9). Really wanted to get under 250 grams, but that's only happening if I use a 450mah 4s.. I attached my rates and tune in the pictures.

Edit: Thought I was getting short flight times, but my voltage scale was off...

Thanks, thats super helpful! My build will get me to ~245g with an 850 4S, which seems the sweet spot. Having some voltage sag on the 1500 4s I ran, but I think it was just too heavy/old battery.

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..
