Who is MEPSKING?
MEPSKING is a professional shop for FPV drone parts. It is a one-stop FPV drone parts online shop that not only offers motors and FCs developed in-house, but also handles parts from famous FPV manufacturers around the world. Although it has a history of over 16 years in motor development, it is a relatively new shop that only began full-scale operations as an online parts shop in 2023.

What is MEPS 85mm Tinywhoop?
The weight excluding the battery is about 55g. Even with a 450mAh 1S battery (about 12g), the takeoff weight is about 67g. Since the takeoff weight (excluding the weight of removable accessories other than the battery) is less than 100g, this is exempt from Japanese "Flight Rules for Unmanned Aerial Vehicles" to the regulations applicable to drones weighing 100g or more. Therefore, it is possible to fly FPV independently without placing a visual observer.

Model variety
The MEPS 85mm Tinywhoop series comes in two motor types: 11000KV and 8000KV. If you enjoy freestyle acrobatic flying, the 11000KV model is the way to go. If you want to take advantage of the features of the ELRS and enjoy long-distance, long-duration flights, the 8000KV model is the way to go.
There is also a Tinywhoop kit for indoor use, MEPS 65mm Tinywhoop , which uses the Meteor65 frame. If you plan on enjoying it mainly indoors, this is also recommended.

How to buy the MEPS 85mm Tinywhoop
MEPSKING is a parts store, so kits are sold in individual parts. To assemble one drone, you need to select multiple parts and add them to your cart.
From the
MEPSKING
homepage, select [FPV Kit]-[Micro Drone] from the menu.
You will then see a screen like this.
Select either 85mm Tinywhoop or 65mm Tinywhoop.
Or click on one of the links below:
MEPS 85mm Tinywhoop Official site (MEPSKING)
MEPS 65mm Tinywhoop Official site (MEPSKING)
You'll then see a screen like this.
The default option selected is 85mm Whoop Kit #G/Frame+Props.
This is the frame and propeller only.
If you scroll down the screen, you will see a list of parts like this.
For the motor and FC, choose either "Kit #E/11000KV" or "Kit #F/8000KV".
For the frame and propellers, choose either "Kit #G (Gray)" or "Kit #H (Black)" .
For the camera and canopy, choose either "Kit #I (Black)" or "Kit #J (Blue)".
Then add "Kit #K/VTX+Receiver".
Select each part in order and press the "ADD TO CART" button, and the parts will be added to your cart, as shown in this screen.

In my case, it took about two weeks from ordering to the product arriving in Japan.
How to assemble MEPS 85mm Tinywhoop
MEPSKING has posted a video explaining how to assemble it on Google Drive, so I recommend watching this first.Wiring the parts
Wire each part as shown in the diagram below.
Attach the included battery cable to the FC.
Match the markings on the board and connect the red cable to [+] and the black cable to [-].
Attach the motors to the frame.
Attach the four motors with the four screws provided.
Attach the FC to the frame.
The white arrow engraved on the circuit board indicates the forward direction.
First insert the rubber damper included with the FC into the circuit board, and then insert that into the frame.
The fixing screws will need to be obtained separately.
In the assembly video provided by MEPSKING, the FC is attached to the frame at this point, but it may be better to wire the camera, VTX, and receiver to the FC first.
Attach the camera to the canopy.
Align the holes on the side of the camera with the holes in the canopy and attach using the screws included with the camera.
The screws are 1.5mm Allen keys (hex nuts).
The shortest screws will fit.
At this stage, if you connect a battery to the FC and scan the channels with the FPV goggles, you will be able to receive the camera image.
At this stage the electrical assembly is complete.
