So. The Kittiwake 6 was supposed to be a long range frame, but really it was too heavy (great freestyle build though). Decided to revisit it, change up the design to cut weight, and go up to 8" arms whilst I was at it. Frame weight is 134g - not bad at all for an 8" frame, and about 50g lighter than the Kittiwake 6!
Turns out clearances are way too small on 8" with top mounted packs, but spot on with 7" props. Of course, bottom mounting batteries is still an option with either size prop, but given the availability of 7" props I'd say they make more sense for most builds.
Build was mostly smooth, the 1.3GHz VTX was awkward though since it's just gigantic compared to the modern 5.8G VTXs that are the norm. Antenna placement for the Rx was also an issue, given the length of the relatively inflexible coax.
Setup was easy with the Matek, even though I had to mount the board at 90 degrees to clear the screws at the side. Remapped the motors, and whilst I was at it I made a custom deadcat mix. The EzUHF system, however, was a complete pain to get set up, and whilst I (naively) thought the latency wouldn't be too bad on PPM, turns out there is quite a noticable delay in action to reaction. I'll be swapping over to Frsky R9M once I can get hold of a module and some receivers, getting GPS coordinates to my Taranis will be nice too.
Flight performance seems good so far though, plenty of float and punch, and it's not heavy on the battery either. Shall be fun to get out in the wilds and really see how it is at range!
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..

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..

I have been thinking about switching to lower frequency radio gear for longer range, should I expect the gear to perform mostly the same (but with longer range)?
Whilst I'm not sure about Crossfire or R9M yet, I have found that EzUHF has quite a bit of latency, not too surprising since it's an old system that's basically end of life now. It's probably not an issue for fixed wing use, but personally I find it just annoying enough that I'm going to fork out for an R9M for this build instead, probably use the EzUHF in a wing instead.
Oh wow, thanks!
I think you may have issues if you use 1.3vtx with the R9. Nice build.
