I've been looking for a frame/build that would help with the up and coming 250g limit in the US, but not sacrifice anything that I love about freestyle, AND be DJI HD compatible. When I saw Tommy tease the 2Fiddy my interest was piqued, and so once pre-orders came online I snatched two frames. My dry weight comes to 180g, and if the weight for the new 6S 380mAh GNB packs are correct, I should have an AUW of 242.5g. This gives me 7.5g of leeway assuming some tolerance on battery weight. Overall, this is a really well thought out and balanced build that should be a pleasure to fly and easy enough to maintain. Well done Tommy!
Build
Whenever the goal is small and light, you can bet that the build will be a challenge. I was expecting the frame to be a bit fiddly to get together, but I'm happy to report that its pretty straight forward, albeit cramped. When i started the build, there were no how-to's, so I made my best inferences based on the stock photos and Tommy's videos. Because of this, there really is no way to get a double stack setup into this frame IF you use the stock photos as gospel. After thinking about it a little more, and considering the extra "long" standoffs provided, you should be able to flip the arms and press-nut plate to the underside and get ample clearance for a two-board stack. Be aware, however, that the camera cage restricts you from building in the full height of the frame interior IF you use a 20x20 double stack or a 30x30 double stack. Tommy included extras of all of the hardware, and every piece was carefully thought out, though some of the hardware choices could have been better (see Issues below). All in all, its a moderate build difficulty, and I wouldn't recommend it for new builders.
Components
I used Tommy's recommended motors for 6S, and I chose a Caddx Vista as well. For the electronics stack, I chose the TBS Podracer AIO because it seems to have the right ratings for voltate and amperage, because it's a single-stack board that is light, and because it has built-in considerations for Crossfire. Speaking of Crossfire, I'm using a standard Nano RX with a Minimortal T, mounted to the underside of an arm. It took a little bit of trial and error for me to figure out, but you CAN make a Vista work with this flight controller.
Caddx Vista & Podracer AIO
At first blush, it doesn't look like this FC supports DJI, as there aren't enough UARTS. However, if you go to the product page for the TBS Podracer AIO, you'll see a section there about adding GPS to the board. Do the steps shown on that page, but with the following changes:
Issues
I'm writing this list knowing that I bought a preorder of a first-run batch of a new product. I expect it not to be 100% perfect the way batch 10 will be sometime in the future. If you read this in the future, you won't have some of these issues. Having said all of that, there were some issues:

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..

hey hey nice build!
Do you know the weight of the podracer aio board?
Did you use the onboard mounting for rx and vtx? if so how is it? not creating any vibrations for the fc?
Thanks :)
sorry bud, I didn't record the individual weight of the board.
No worries. Contacted TBS they said it's 22-23g :)
