Check out this 35mm-prop BNF Whoop-style aircraft!
The Meteor 65 PRO is one of the first micro drones to be released with 35mm props, as opposed to the standard, which is generally 31mm props for 65mm aircraft. This means more wing per prop and more thrust potential overall! This is only possible on the Meteor Pro frame with a very small FC like the Betafpv 5a F4 Flight Controller.
Here's what Betafpv has to say about this aircraft:
Meteor65 Pro comes with 35mm propeller for power improvement and flexible flying experiment. Beyond that, it has almost the same components as Meteor65, like F4 1S 5A FC board with built-in ExpressLRS receiver, up to 350mW M03 VTX, 19500KV 0802SE motors etc.
Konw More About ExpressLRS
ExpressLRS is the most popular radio link in 2021. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. Know more about the ExpressLRS project on Github.
In order to meet the FPV polit's requirement for ELRS whoop drones, the ELRS 2.4G version Meteor65 Pro is here.
ExpressLRS is based on Semtech Lora SX127x or SX1280 hardware for RX and TX respectively. it aims to achieve the best possible link performance in both speeds, latency, and range. At 900 MHz a maximum of 200 Hz packet rate is supported. At 2.4 GHz a blistering 500Hz is currently supported with a custom OpenTX build. This makes ExpressLRS one of the fastest RC links available while still offering long-range performance.
More and more vendors start to support the ExpressLRS radio protocol in different parts, like radio transmitter with ELRS in stock, drone with built-in ELRS receiver, ELRS TX module for JR bay, or Nano bay. BETAFPV team take part in this project and provide a series of ExpressLRS components.

Meteor65 Pro Frame & 35mm Propeller
Meteor65 Pro frame has the same perfect performance as the popular Meteor65 frame. The lightest lower profile 65mm frame to fit 35mm propellers. The battery slot is closer to the center of gravity for a smoother flying experience, and you will land on the motor screws instead of the battery.
BETAFPV exclusive designed BT2.0 connector has broken through the bottle-neck of PH2.0 connector. BT2.0 connector has decreased internal resistance of connector effectively allowing more current to be transferred, which means it supports 9A continuous current (15A burst). This means stronger power and longer flight time on 1S brushless drones while PH2.0 just supports 4.5A. You can enjoy more flight time without disturb of low voltage warning due to reducing voltage sag.
See the graph below of comparing the BT2.0 connector and PH2.0 connector (solid pin version) in BETAFPV 1S 300mAh battery. The discharge current is 9A in this test. The BT2.0 has double the time (about 2 minutes) and a 0.2v improvement in voltage sag.
0802SE 19500KV Motor is a lightweight 1S motor, compared with the 0802 series brushless motors, it is not only significantly reduced the weight which is only 1.83g/pc but also ensuring the awesome performance of power and thrust. Lead wire soldered to the PCB, which allows you to repair it easier once it disconnected.
Now the default flight controller firmware for the Meteor65 Pro ELRS is updated to Betaflight V4.3.0 RC6, which supports ELRS V2.0. For the ERLS V1.0 version, if you need to update it for supporting ERLS V2.0, please refer to the link below.
