The canopy :
I've updated the canopies with a design that requires little/no support. To get the dual colors, I swap the color of the TPU after 2-3 layers. I've even had success printing the first layer with PLA and then switching to TPU. There's a version for 12mm lesnses (runcam nano 2, eos2, etc) and 10mm lenses (whoop style cam, caddx ant, etc). I also made a 35-40 degree and a 45-50 degree version for each canopy.

The frame:
I've made a change to how I print my frames. I've found the best results to be printing with 4 walls all the way around and turn the cooling fan off. This made a big different in layer adhesion (i'm sure many already knew this). I did try putting a box over fnished prints and turning the bed to 100degrees to help cure the PLA, but I didn't see any improvment with stiffness or rigitidty. Plus, I accidently warped a few frames when trying to cure them.

I have yet to do a fully printed frame build but noticed your build a while back and and I have saved one of your older versions in my print queue to build one up using surplus parts. I was wondering if you would be willing to do a frame with only the four hole motor mounting and no three hole mounting option. I ask only becuase I have had multiple builds break at the motor mounts that have all had the multi-hole motor mounting options?

I think its funny that you mention this because I was thinking about it on the way home from work just a few days ago. I'll include a link to a 4 hole version that I made, but I have yet to test. I had contemplated make a version with only 3 (maybe only 2) holes since I never use all 4 screws to mount my motors. However, for now, here's a simple 4 hole version. https://www.thingiverse.com/thing:5529776

You rock man, Thanks! Yeah I plan to build one up and willl use larger 4 hole mounted motors. I've had three or four frames break that had the multi-mount option and really appreciate your efforts here. I’ve two builds in front of the Spark but will be sure to add it here as well as Thingyverse.

do the printed frames get mushy after a while?

no, i havent experienced any changes in rigidity or stiffness over time. i do notice slight changes on stiffness between flying on very hot summer days compared to very cold winter days.

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..
