INTRO
After the success of the Modulus 65 (and buying a domain), I decided to move ahead with MaximusFPV and design a few micro frames. The first thing I wanted was a 2", but not just any 2". I wanted a Maximus 2". I do lots of flying in my front yard which is pretty tight, as well as in playgrounds and things like that, so a 2" was just the right size. I also knew they were awesome after having a BQE Mini Pixel last summer.
So I set off designing one.
After probably half a dozen sketches, I had something I was satisfied with. It combines my favorite parts of a) other frames I had used and b) previous sketches into a compact, lightweight, and durable package. For me, of course, it checks all the boxes: wide slots for battery straps like the AirBlade micro strap, M3 all-metal hardware (Al standoffs and Ti screws), lots of camera choices (large or small AIO or micro board cam), 16x16 or 20x20 stack mounting, 20mm standoffs for tons of space (a friend of mine is planning a Split Mini build), antenna protection, slots of zip ties to hold your battery leads, and of course LOTS of color choices.

THE BUILD
If you haven't done a 2", then be aware that they can be tight but they don't have to be quite as tight as mine. I designed it so the arms were just long enough to admit the 4 EMAX Bullet 12A ESCs I had laying around, but I would recommend a 4-in-1 if you're starting from scratch. Very clean, very light, very simple. Mine ended up around 100g AUW which is right about where it should be with a 2S 450mAh, but a 4-in-1 could cut even a bit more off of that. With 4 separate ESCs it also meant I cut my wires pretty darn short, so these motors can't be used on much else unless I lengthen them again. No biggie; this one's here to stay.
Other than that, it's a fairly straightforward build. Supply your own stack hardware (M2 for 16x16 or M3 for 20x20) and you're golden. I chose to use an AIO camera since I have a soft spot for the little buggers, having been around in the days when everyone competed to build the lightest backpack. As great as micro board cams are, these compact AIOs are just so clean and easy, and the ones with OSD wires are so handy.

CONCLUSION
Obviously I think you should buy this frame but I may be slightly biased. If you do, they're discounted $5 for this preorder session and I have 9 spots, so go snag one quick!

Seem like a pretty good flight. Is that stock tune? My 2 inch with RCX 1103 motors kinda have some wobble to it. I'm using a similar frame, the EyasX2.

Thanks! No, I spent a bit of time getting the general tune and even 15 packs later I'm still tweaking little things. I would rtecommend everyone learn tuning early: it's difficult but it pays off bigtime. I have heard someone mention that before. The EYAS X2 is only similar in that it's also a 2" true-X. However, it's smaller, has a different pod design, and has many other noticeable differences. If I were to give you a tune, then, it would be useless.

I was just wondering what kind of range of values are needed as I have built a couple of 5 inchers and this is my first time with a 2 inch and tuning feels a bit different. Great design :)

Again, thanks! It actually varies a lot. Some say you lower P and D, some say you raise it... Depends on filters and setup and all that. I use the "Tuning with Stingy" video that's a year old as a baseline, but usually adjust up or down just based on past experience. My P and D usually end up a bit higher. Mine are by no means perfect, either. But I have fun, so why waste more time on it? I'm not a DRL pilot, just a dude with a passion.

Save 7% on the T8SG Plus with the coupon code "Toyho" at Banggood This is a surprising little transmitter. The Jumper T8SG Plus is a compact, multi-protocol radio tailored for FPV pilots. While it's not the cheapest transmitter on the market, it's certainly a huge leap forward in terms of quality and flexibility. The multi-protocol module lets you fly most toy quads as well as hobby-grade FPV..

The Diatone GT-M200 is a racing/freestyle frame that features an aluminum alloy cage and 6mm replaceable arms. The goal of this build was to balance price, features and quality. It features an F4 flight controller which allows an 8khz gyro update and PID loop frequency and the latest filters. Additionally with BLHeli_32 it supports the DSHOT1200 motor protocol and custom startup music. This also..
