The concept: After the toothpick trend grew like crazy and everyone hopped on board to make their own versions, people started making them bigger and bigger and TBS came out wit this "podracer" design. I've always been a fan of MattyStuntz style high cam tilt (60-65 degrees) and call my toothpick desgin the "Full Tilt" and it has a pod that allows for full on 90 degree cam angle. This TBS podracer is interesting in that the camera is positioned near the rear of the quad rather than the middle like most frames of this type. I was curious and liked the idea of the frame being open source so I picked one up.
The Build: I decided that this build would be "The Ghost of Deezy" where i'd be bringing Deezy back from the dead once again but with current parts. The bulk of this build came from parts that I took from an Airblade Intrepid 4" that I ended up scrapping. For the sake of not being redundant, I wont repeat the build list as it's all down below but I do want to highlight a few things: First, the Jhemcu AIO FC/ ESC is great, I've only managed to blow up one so far and im pretty sure it's only because it put it under some pretty extreme strain. Second, the Airblade 1404 4850kv motors seem best suited for racing, they have tons of top end but are kinda "meh" in the low end, the 3800kv variant is far more efficient and is a more practical motor just generally speaking. For the feel that I was going for ,1404 felt underpowered and my bearings sounded a bit rough so I ordered some Brother Hobby 1504.5....shipping took like 10 days for some reason so during that time I took some old RotorGeeks 1407 3200kv motors that I thought I'd never use again and stuck them on the quad. I didn't have many 4" props that would fit other than the Gemfan Hurricane 4" that can be either 5mm or t-mount and with the Hobby King warehouse being nearby I ordered a bunch of old 5mm mount 4" and even some 3.5" props that were probably made before I even started flying. This experiment quickly made a turn for the old school...but there's reason for all of this......
--Update: I broke it. I Mattyflipped it into a tree and snapped both plates but the arms were fine. Luckyily I know someone who cuts carbon locally so I had some more plates made and got it back in the air within a few days. I've also redesigned the pod to have less of that "rat rod" slammed back feel. In my experirence, having the camera at the back of the pod like that is only beneficial if you tilt the camera as high as it can go and are using the quad for racing. When it comes to freestlye the original pod feels pretty terrible, honestly, so I've just shifted the camera forward so that the front of the lens lines up with the center of thrust. The main benefit of flying a "tower-style" (see "toothpick" quads) is that the center of mass is lined up with the center of thrust and having the camera lined up with both of those makes for a less latent feeling, quick response quad. Note: the camera is still shifted back from where it would be on a most tower/ toothpick style quads, since I'm flying around 60-65 degrees I'm trying to figure out what physical positioning of the camera will provide the best moment of inertia for "blipping" the throttle and sending the quad sailing.
Update 6/17/21- I've remixed the pod twice now, the first revision postions the front of the camera lens right at the center of the frame (from front to back) and the second revison is more of a standard toothpick style pod that can be flown at high cam angle. After watching one of those recent Chris Rosser videos where he explains how the typical way that most people mount antennas (sticking out the back) can cause resonance that makes tuning more difficult, I'll probably revise the more standard style pod with better antenna mounting soon and put both styles on thingiverse.
Some flying. This edit is some high cam tilt flying at a park. I have some 3d footage that i'll be posting soonish. Stay Tuned

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..
Read moreWith 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..

I'm running the same antenna on mine, the TBS one just lost its cap so I got these from my tiny whoop, works great, love the white canopy!
yeah! I like these lil sigma antennas! I had specifically bought a TBS triumph antenna for this build but the current batch at my local shop are all a little longer than they used to be and it made it tough to fit the triumph in this build w/o bending up the antenna to uncomfortable levels. On the white canopy, i've printed a couple now but in some of these pics it's just the stock tpu canopy spray painted white, it holds up suprisingly well! Also, I like your podracer setup too, I def checked out your page for inspiration for raising the pod. How's it holding up?
it's an amazing build, super silent and super fast, same thing with the long tbs antenna type, for my sigma antenna I just put a rubber band around it to fix it to the canopy so it doesn't shake loose in flight, these ufl ports are not trusty at all!
I also want to get this but I'm wondering if 1404 3850KV motors also would work?
