Recently I've built a 5" Freestyle quadcopter based on the best value components - not the cheapest but the best price/performance ratio (i.e. bang for buck). The components I've chosen plus comparison to alternatives can be found in the component selection article here. As it stands the build cost of this one is around $150-$170 depending on which specials you can take advantage of. I see the RC Addict (His YT channel here) has done a similar thing for a race build and he refers to it as the "The cheapest quad worth building"
This quad has since been built, setup, flown, adjusted and then flown a lot more. I'm now in a position to pass judgement over all of the components and will then cover as the quad in total. For each I'll look at the positives and negatives and then go into a little more discussion with my recommendations
Discussion and recommendation
At the time these Emax Eco were chosen as they were the standout budget motor. They have been available for $10-$12 and based on how they perform represent outstanding value - the top equal standout recommendation for this parts list. Emax had the original breakthrouhg brushless motor in the quad scene - the RS2205s which changed the industry. While others have caught up since they still make well-researched high quality motors. The Eco series draws off the learnings from the LS and RS2 series - they remain VERY light but have increased the bearing size from 8mm to 9mm to improve durability significantly. Retained from the RS2 and LS series however are the thin magnets. Although these mean the motor doesn't make the same peak thrust as heavier motors with larger magnets, it does gain in improvements through being lighter, more efficient and smoother at throttle transition. This makes it a great match to freestyle where these positive attributes tend to be preferred over peak thrust @ 100% throttle. In use these are very nice motors to fly. They are quiet, smooth and cause less battery sag and longer flight time than more expensive motors I use such as the brother hobby returner R6 2306.
Interesting that based on the success of the Emax Eco, iflight and brotherhobby have followed suit. 3bhobby also have the training motor although this may have just been out when the emax eco was launched.
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.
This review is for the Fullspeed Toothpick Pro, the more robust 4s-capable micro quadcopter made by Full Speed RC. It is available from the following retailers that will ship internationally with options for FRSKY, Flysky, Spectrum and now TBS Crossfire as well:
If you are looking for the the standard 2-3s Fullspeed toothpick, the full review of that can be found here and is available below:
Fullspeed RC were the first to market with a bind and fly quad inspired by Bob Roogi's "toothpick"design - an ultralightweight quad based on small motors and 65mm props suitable for park flying. This was a very good park flyer - quiet and well built with good performance on 2s or 3s. It does have a full micro camera and VTX meaning it has a very nice FPV feed but is slightly on the heavy side. This model has obvioulsly been successful for them so they have quickly followed up with the Fullspeed Toothpick PRO. Specs compared with the standard toothpick below which I will discuss further:
