The Turbobee 120RS is an ultra-lightweight micro quadcopted that loosely fits into the new 'toothpick' class. It is available in 2 variants below (2-3s and 4s), each offered with multiple receiver options (frsky, flysky, dsmx, futaba ad even TBS crossfire:
My review is based on the 2-3s version with 1103 10,000kV motors as above
iFlight is a brand that is rapidly growing and is going some impressive things in the FPV space - everything from micro quads to the Giant X-Class rigs. They have always been middle range for value but now they are bringing polish to their products. Here I've reviewed the Turbobee 120RS 2-3s micro. It does fall into the toothpick class and yes, although it comes with Gemfan 2540 props it does fit the 65mm bi-blades.
What is included?
1x TurboBee 120RS Micro FPV Race Drone
1x 10*100mm Magic Battery Strap (It's the crappy strap style, take a look at this article for options)
1x 10*125mm Magic Battery Strap (as above)
1x XT30 Male Connetor Cable
1x 3D Printed TPU Antenna Mount
2x 40mm Protective Tube for Antenna
1x 3D Printed TPU Fixing Mount
8x Gemfan flash 2540 props (but no 65mm props)
In summary it's just a basic kit with the quad, the receiver you chose, some crappy battery straps and props
A Closer Look at the Specs
The manufacturer has stated this quad is suitable for 2-3s. I don't believe this is right. I did try on 3s but motors were hot and the battery had unbearable sag. I'd strongly advise against 3s and so all my testing was done with 4s.
A quick note on weight
When the toothpick formula was devised by Bob Roogi (KababFPV) it was based around an all up weight of no moe than about 72g using the 65mm bi-blade propeller. As more people have tried to enter this lucrative space we've seen more variation driven by innovation or by the parts available to a manufacturer. Although the Turbobee has nice components in isolation, they do come together as a fairly heavy package. Below is a comparison between some of the popular options at present. This is with 65mm props on the 120RS as well - the stock 2540 props are much heavier. This weight really comes into play in flight performance because not only is the weight without battery heavier, but a larger battery is needed as well to get meaningful flight times meaning a double disadvantage. And, all this on the same sized motors...

FPV and control link performance
As good as the FPV signal is with the iflight vtx, I just don't like the camera. Not because of the image qualilty but because the 16:9 variant as included here has a poor vertical field of view. This means obstacles tend to 'sneak up' on you more than those cameras with a larger vertical field of view. Even the same camera in 4:3 format is a vast improvement as you can see in the DVR from the Hobbymate Asteroid review.
Control link is the best I've experienced in this class of quad hands down as mine came with a genuine XM+ receiver which is vastly superior to the onboard unit on the Sailfly or the nano v2 unit on the toothpick. All other things being equal I've been out over 1km on these.
As you can probably tell I was disappointed with the performance. Compared to other models in the same segment the flight time, handling and speed wasn't there because I just don't think the components are well matched:
Below are some pics of the comparative weights and the painful task of extending motors wires I had to go through. Bad enough on large motors but excruciating on micro motors!
Outcome and conclusion
So flight is much better, more in line with what I'd hope for. 64g is very light for 2.5 inch micro, in fact nothing has been this light since the original Leader 120 which is the same weight as this when a proper camera is installed.
Sadly I had an unrelated issue (my own fault) that damaged the ESC so it is grounded after only a handful of flights. I'm not in a hurry to fix it though... Why? Because the quad I've build below is essentially what iflight have moved to in their 4s version, furthermore the Fullspeed Tootpick pro has since come along at the same weight, with larger 1106 4500kv motors capable of 4s, a better FPV cam and VTX AND at a lower price. My review of that quad is here.
I will be keen to complete this upgrade to see it through and although the components are very nice, it's hard to recommend this one unless you can get it on a significant sale. My thoughts are this is a quad that has been rapidly put together to take advantage of the hype in this class without thought to balance. The components are top rate, just not together in this combination.
