Birdbrain RC Morningstar 5 "Martini Special"

Did 3 identical builds for the 2019 race season - did one white, one black, and couldn't pick a colour scheme for the third one until I realised I had TPU in all the colours necessary for a Martini Racing colour scheme. 13 filament changes, totally worth it!

Mostly the same as the Mahou Shoujo builds from last year, frame updates consist of more reinforcement on the baseplate which makes it way stronger and more rigid (even used FEA in Solidworks to help work out where to put the intermediate braces), and a fin on the pod which protects the VTX antenna (sheared a couple of pigtails in big crashes) and helps with turtle mode.

The pods for all 3 were printed in TPU - Martini Special is all Rigid.ink, Black is all Sainsmart, and White is white rigid.ink and purple Sainsmart. Baseplates are all cut from various grades of HDPE - Martini Special is red PE500, Black is PE300, and White is PE1000. The black build also has a Hobbywing 45A rather than Racerstar 35A, because I had it handy.

Just need the weather to improve so I can get some laps in before the season kicks off!

That Martini pod is awesome. Fellow F1 fan.

What's the weight sans battery, if you don't mind me asking? I was thinking about this type of build yesterday. Had no idea someone was already on it. Thanks.

Not light! 376g dry, of which 144g is frame. For me personally though I'm definitely not at a skill level where a lighter frame would make a difference, and the durability and low maintenance for race day is much more valuable.

Thanks for the fast response. I understand completely. Will look forward to flight vids if post them. I'm following now.

Good lord, these are some of the most photogenic frames I've ever seen. If you start selling these, I WANT IN.

Beautiful work, yo.

Jun 21, 2021

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..

Build a DJI FPV Cinewhoop - QAV-CINE Freybott Edition

Mar 04, 2021

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..
