Is that the weight with TBS gold standoffs the lightweight weight upgrade for the powercube??How does the quad stand up to crashes?

bensonk   Sep 27, 2018 

Yeah, gold plated aluminium is a fair bit lighter than brass and plenty strong to hold the cube together, so you shed a few grams by going that route.

I haven't done much crashing, but so far it holds up pretty well. Biggest problem is the motor leads on these PRY motors seem to have weak solder joints or something, so the silicone can come off the magnet wire and you have to get in there and solder it back on.

The other durability problem is that canopy from shapeways is a bit brittle. Thankfully, things have gotten even better since I did this build -- now you can work around that by using a split mini v2 and the stock canopy.

I built a 4 inch atom with 1608s 3200kv and the tbs 25amp 2 in 1 esc's ran it on bullnose bi blades 4x4.5 1300mah 5s and at 60 to 70 % throttle I could get 7 minutes fly time if I just cruised I'd get 11 minutes if there wasn't strong winds and it was just as fast as my 5 inch on 5s and far more agile and better acceleration and 6s was stupid fast that's how it died I hit a dump truck

what sort of range do you expect?

bensonk   Feb 21, 2018 

I'm thinking somewhere around 5km, but we'll see. :-)

What kind of flight time do you get on it? The battery seems very excessive. My 5’’ would feel really heavy in the air on that 2300mah pack.

bensonk   Feb 21, 2018 

About 12:30 on the 2300 pack. About 5 min on an 850. And yes, that 2300 pack is totally excessive, that's the whole point; flying a really heavy quad means you fly faster for a given camera angle, which in turn means better punch through headwinds. I won't usually fly it on a pack that big, but the fact that it flies well with that much lithium really increases the diversity of spots I can hit.

How do you like those motors? I thought about using them on one of my last builds but went with DYS instead.

bensonk   Feb 18, 2018 

I've flown 4 packs on them, and I'm really impressed so far. They came with a glowing recommendation from gapit, so I have pretty high expectations.

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..
