The Zeez Racing Combo is a F7 flight control and 4x60A BLHeli_32 combo that includes 4 plug and play discrete, addressable LED strips. It is in the standard 30.5mm mount size meaning it will fit 5 to 8 inch quadcopters. It can be considered a premium set based on the retail price of just over $100 but the cleverness in design and execution in quality make this stand out for me. Zeez is a relatively new company in the FPV scene based out of Italy that looks to be made up of a group of racing and freestyle pilots. At this stage they have a race frame available plus an ambitious flight control-ESC combo which I'm reviewing here. Individual components are also available: Design has been completed in Italy by this team based on their needs. We can see immediately that this bottom up design has made for a lot clever tricks to make building and setup cleaner and more efficient with a heap of features. Before we go into that let's look at the core specs and discuss the benefits to the average punter:

The Emax Eco 1404 is a newly released lightweight brushless micro motor and is available in both 3700kV and 6000kV variants. It follows on from the successful Emax Eco 2207 and 2306 5" motors which have redefined the budget motor offering with a much higher build quality. I have been using the 3700kv variant on a lightweight 3 inch HD build with battery sizes ranging from 2-4s and my review is below. Build objective The objective of this particular build is a light, stable 3 inch HD platform that has exceptional control so that I can fly like a regular quad or fly around objects in close proximity at low-medium speed. Basically a cinewhoop without limitations of duct performance or weight. The lightweight 1404 fits this brief well with the large diameter to height ratio making for great control in the lower rev ranges. The smaller magnets on the eco series means the motors are not a notchy so smoother and much more effcient at the cost of a bit of top end speed. I quickly need to disclose my bias for Emax ECO motors as I've had a really good experience with the larger ECO 2306 motors that I use on my 5 inch sweet spot build that I built here and reviewed here. After a year of use and abuse the motors are still performing well. They are not the most powerful but are light, smooth, efficient, reliable and very durable which are excellent characteristics for a freestyle quadcopter. Building on this foundation Emax have released the eco as a micro series in 1407, 1106 and 1404 sizes. I leapt at the chance to order the 1404 as this is my ideal lightweight 3 inch size for efficiency and smoothness. 1407 is a good size for a 'power' 3 inch build (or even a 4 inch build like this one) but not what I was wanting here. 1106 are better suited for a power 2.5 inch build. I chose 3700kv as a good motors speed for 4s that could run more sedately on 2s. I have no interest in 6000kv in a motor this size as you are limited to 2s batteries which don't suit me. Motor details are below:
Introduction The Rush Tiny Tank is a nano class VTX that has power output options of 0, 25, 100, 200 and 350mW output. It uses smart audio for parameter adjustment via betaflight OSD and has lock on technology that supposedly helps the signal. Perhaps more importantly it is very, very small and very light (1.6g). I used this VTX for my recent ultralight 3" TP3 build which I documented here. Quick update: at time of writing there is a coupon code to get this VTX for $17 with code BGRush12 The code expires 31 May 2020 or when they run out of stock Background
Rush FPV as a brand is relatively new but made a huge splash with their premium full-sized tank VTX. Many found these vtxs as good if not better than the best-in-market TBS unify VTXs but as the name suggests, more robust. They followed the initial Rush Tank with the Rush race (similar but no mounting points and recently the rush mini 20mm mount. Their latest version is tiny tank reviewed here and at 1.6g is designed for micro builds or even racers (where 350mw is much more than you are allowed to run anyway). For me it is a perfect size for a toothpick build where keeping it light is the build. Due to it's small size install was simple and I was glad to see it offers multiple wiring options as below - mounted in line with camera or separately to the flight controller. The NamelessRC AIO412T is an All-In-One flight controller and ESC. It has 25.5 x 25.5 mounting which is the common standard for whoop and toothpick boards. It includes and F4(11) flight controller and 12a x 4 BLHeli_S ESC set. This particular board is optimised for custom and toothpick build with larger motor and component pads, a horizontal USB port and upgraded 12A ESC FETs This board was originally a NamelessRC collaboration with KababFPV and he looks to have given some thoughtful feedback on pad layout for custom builds. For this reason I chose this board for my custom TP3 build here. Specifications from the manufacturer are:
The GepRC GR1204 is a 1204 sized motor (12mm wide, 04mm high stator) suitable for micro quadcopters that is available in 5000kv. Specifically this stator size and kV has been identified as an ideal size to build an ultralight 3 inch build like a TP3. I bought mine from Banggood here to use for a ultralight 3" TP3 build that I've reviewed and discussed here. The GR1204 uses modern design and manufacturing so that weight is just 3.8g per motor (no wire). The stator is 1mm wider than early 11 series motors which offers slightly better torque and efficiency which is needed to better control a light 3 inch propeller. They are in a gold colour that looks better than the stock image suggest - they are beautiful in real life. Mounting for propeller is a standard 1.5mm shaft with 2 x m2 screws for a t-mount.
The "toothpick" series of ultra lightweight quad was made popular by Bob Roogi (Kabab FPV). all original parts can be found on his site here: https://fpvcycle.com/ After enjoying the original 65mm toothpick builds I was very excited to build a larger, more powerful 3 inch "TP3" version but I've never been able to buy all the parts owing to the popularity. So I've decided to spec my own TP3 build inspired by his specifications. Since this quad is essenially a sum of components I will do breakout reviews linked in this master review which ties it all together, Here are the parts I've chosen Frame - ZJWRC 115X
This frame has a truly unforgettable name and a waste of time canopy but the baseplate is TOUGH and the hardware is actually useful. At $14 the price is ok and it is always in stock. See more details in my frame review here. Premium alternatives include the original TP3, racer-x twig, and more but for me if a frame does the basics well I don't bother with something expensive. I'm pleased to say this frame does do the basics well. If you are looking for something cheaper and lighter consider the Eachine Twig frame at $8 but personally I prefer the stiffness of the ZJWRC 115x frame I used here. |
