thingiverse

This is a mod for meteor pro frame of Betafpv. For details please visit my post at instagram: https://www.instagram.com/p/CjBv2YfoVi8/?utm_source=ig_web_copy_link and... https://rotorbuilds.com/build/30190 There is also a new mod for flying upright: https://www.thingiverse.com/thing:5536503 https://rotorbuilds.com/build/30483 --------------------------- In early 2020 I designed the first pusher mod for the meteor frame. I have adopted this principle on the new Meteor pro frame with 35mm props. Why pusher? ------------------ The goal is to fly a light whoop on 35mm props. However, you can only mount Betafpv FC (external VTX necessary) in the Betafpv meteor pro frame, which means a higher weight. The frame of eachine (uz65) got similiar problems and overall is not as good as the betafpv pro. Why not mounting another fc with aio rx and vtx? The problem is it doesn't fit in. You would have to put the flight controller higher with spacers. This causes the problem that the whole profile of the whoop gets higher which also negatively affects the center of gravity. If we flip the frame and add new mount options, I can fly any flight controller and have a compact center of gravity. I can also fly different lipo positions which is a cool way of customizing. Advantages of my Mod: - Fly any flight controller on the Meteor Pro Frame - Easy to reach under 20 grams on 35 mm props !! - Use diffrent lipo slots (diffrent lipo size) - New mounting option for digital whoops on 35mm props - Fly different lipo positions. Customize your whoop.... 1. The Classic racer (Picture 1) Full Size Canopy on top, lipo at bottom. 2. Low profile racer (Picture 2) Camera in front. Lipo at bottom. 3. Duckface whoop (Picture 3) Top mounted liposlot including camholder for 199c fpv cam. 4. Low profile freestyler (Picture 4) Camera in front. Lipo at top left to right or right to left. What do you need? -------------------------- - Meteor Pro Frame and 35mm Props - M2 nylon screws and nuts (min. 5mm long) - when using low profile mount longer 2x M1.6 screws - printed parts which u want - Hardware What do you have to do ? ----------------------------- - Remove the lipo slot of the meteor pro frame - turn the frame upside down. Remove two struts per duct. (Improving airflow+weight saving) - Drill holes and use nylon/plastic screws for a stack build. (see pictures). - Place the flight controller, new printed lipo slot where u want and motors. - shorten the nylon/plastic screws - mount props upside down !! (See pictures) NOTE: ------------ - It is really important to soft mount the flight Controller very well. The screws that holding the flight controller in place must not be tightened too tightly or too loosely. (that is why u have to use m2 screws with nuts and not these short fc mounting screws!!) - The holes of the printed parts are small. If this causes problems use a lighter and heat very slightly. - check that the Flight controller is placed correctly and does not press on the frame. - If the flight controller presses on the frame, there are the following solutions ---> Mount the flight controller reversed ---> cut away pieces where the Fc is pressing. If you did a clean job you will have a powerful whoop. Its worth it. https://www.youtube.com/watch?v=mVftNbeaet8 I recommend the Classic and Low profile racer. Also for freestylers. My tests have shown that the performance is most balanced. Note: When flying top mounted versions i recommend to use two small screws as "landing pad" to give props more space frome bottom to protect them. Screw them in these empty holes of the frame (left and right). The Diamond meteor Pro ----------------------------- Since we know how the mod is done. What are the best parts? This is my setup. - Happymodel Diamond Fc - Gemfan 35mm props - 0802 hglrc 25,000kv motors - 199c fpv cam (or Foxeer Pico) - 2/3 nylon screws per motor - 20 awg bt 2.0 lipo cable Configurator: latest bluejay ESC Firmware 48 khz pwm freq. Betaflight 4.3 additional --------------- The cam mount is remixed. I only added a spacer that the cam mount fits when using a diamond Fc. Thanks @Jakob_Duus. You can also use a Fc bumper as a spacer for different cammounts. Print with supports. The lipo slot is for 300 mah 1 s batteries. You can print with or without supports. i will add a 450 mah lipo slot next. update 13.10.22 --------------------- added liposlot for 333mah 1s 60C battery. seems to be a good alternative for larger tracks. Higher C rating and a little more mah. https://www.mylipo.de/Lipo-Akku-333mAh-37V-1S-60C-120C-BLADE-mcp-x total weight without sticker and short bt 2.0 cable is 9.8g. update 15.10.22 ---------------------- added antother new and universal liposlot https://www.thingiverse.com/thing:5567837 update 01.11.22 --------------------- added a low weight remixed runcam nano 3 canopy https://www.thingiverse.com/thing:5601159 update 02.12.22 -------------------- added a stl called "strut for pusher". This is a stabilation when using low profile version or using a canopy which is mounted front and back. It helps that the flight controller stays in place. Mount on top left to right. Print in TPU 50-100 % infill.
