New life for an old school kwad. JJRC JJPRO P175 on a diet :) Removed the motor guards/landing legs. Replaced the huge stock receiver with an RX2A Pro receiver, changed the stock vTX antenna out for a Lollipop and replaced the old school bullnose bi-blade props with 4032 Windancer tri-blade props. Nearly a 45 gram weight reduction so far.

Next phase is to replace the stock camera and vTX with more modern micro equivalents which should easily knock off another 30-40 grams. The weight reduction so far has already made it fly great for almost 4 minutes on 850mah Tattu 4s batteries. Almost the same flight times as the stock 1300mah 3s battery with an incredible improvement in overall performance.

Happy flying my friends!

Will update after phase 2 is complete.

little thing looks awesome. how does it perform?

OptimaZe Apr 03, 2021

It performs well for what it is. It doesn't come close to the speed and agility of today's 3 and 4 inch birds, but there's something about these heavy old kwads that just feels good when tossing them around.

Oh my goodness me! I have one of these sitting in a box in the basement somewhere. It was my third 'racing drone' and largely terrible. But this is a great project, keep us posted! :-)

These things were definitely far from great out of the box. They flew pretty well with some tuning though, and even better with a firmware flash. They certainly don't fly anything like a modern day 4 or 5 inch kwad, but that's what makes this project fun ;)

Build a 5" Long Range Drone - Transformer Ultralight

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..
