Tehllama Floss2.1 6S Hybrid 2019 Race Season

This is the template for my 2019 racing setup. I was able to cobble this together on black friday from ProgressiveRC, Pyrodrone, and some older GetFPV sales. That said, this is the first RotorBuilds upload I've made where cost isn't in the top three for considerations. For me, this setup still stayed under $300, but cloning it without the benefit of black friday sales it would go a ways past that.

The frame is a hybrid (5" front, 6" rear) Floss 2.1 - this is my third such frame after I happend into testing out this setup when I broke an arm at a race and only had a 6" boomerang to throw on the back. After one heat on that setup, that's been my go-to frame layout for the last six months. If this setup is good enough for Evan Turner to dominate at MGP Nationals, it's more than adequate for me. Curiously, this comes in at the same weight (within 2g) as Evan's, and these motors are right around 1850KV, making this a really close clone - which I didn't realize until two weeks after I took this out for a maiden.

Aesthetics were priority #2, so this is rocking a cherry red RIT dyed PHX-3D Canopy, Red CLRacing LEDs, a TinysLED Rainbow panel backlighting the canopy, an extra CJMCU 8-LED panel on the back, and it mostly rides on resplendently red DAL T5046C props (although I also really like how it flies on Gemfan 5149's and 5055's). The pictures here don't do it justice for how good it looks.

The PyroF4/Furling combo is really good for this - I've added the big honking 35V 1000uF capacitor on there, and customized the BLHeli_32 settings (mostly just lowered the ramp-up, set timing to 22deg, and changed the startup tone to the 'Hurry Up Mario' polyphonic one. Really solid so far, but I've only put a dozen packs through this thing.
The VTX Pit Pin I/O works really well on the V2.1 Pyro board as well, I was actually quite surprised at that. I wouldn't bother with this ability on cheaper VTX options, but with a Unify it works really well (cheaper ones will just spray the entire band a full power sometimes) - but the HV Race is a really good value, and I don't see a reason to fly anything else since this isn't a penny-pinching build.

The F60-ProII's are great motors - no surprise. Remarkably smooth and spin really well despite being 8mm OD bearings - they're really 2207.5 stator motors, and clock in closer to 1850KV, but that works exceptionally well on this setup overall. This thing makes for a surprisingly good proximity rig on 4S with 1300mAh batteries and no other changes. Obviously it really shines with a Pulse 6S 1050 or a CNHL 6S 1000/1250mAh pack on there, and it absolutely screams.

This build is getting me results.

I've already posted my best racing result to date, making the A Main at local (BMPR) race first outing this season. The control feel I'm getting are genuinely excellent.

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..
