    After flashing the bootloader you can flash the AM32 firmware. To configure AM32 and upload firmware you can use the Multi_ESC config tool using Betaflight passthrough. Alternately you can use the Online-ESC Configurator to flash or change settings with any web browser that supports web serial. I will make a video on this topic later.

    Don't know where to post this so I'll just post it here.
    Here is the video about flashing the AM32 bootloader on a blheli32 ESC.

    I was also surprised. Especially the speed controller the size of a postage stamp held up extremely well. The weapon was meant for INDI or Planet Robot. Low weight and not too much damage but lots of noise and spectacle :) You could tell by the reaction of the newcomers... they all wanted to fight Cookie Monster II. This time I had a 4S lipo in use so the RPM's were a little higher than planned for Planet Robot. Anyway it is a nice machine that I will definitely use again.

    And it's great to see you guys there, it's always nice to see how helpful you are. bat_boy asked twice if he could help me and Runsler helped my father last time in Bochem when his LED stopped working. I really appreciate that.

    Maybe for beginners, tests and special robots we should set aside some more time for fun-fights and demos.

    For the Raptor competition it seems most of us agree with a 1KJ limit and no restrictions on parts.

    Right now that would be the same rules as for Feathers.

    The only difference might be, that with Feathers the arena determines the limit and with Raptors the result of the previous event.

    Again... this is just an idea and interpretation of what I read here.

    I know for a fact that:
    For new participants damage is very important. they are often Young participants who have just enough money to build a robot. Money for spare parts is often not there, nor is knowledge of how to prevent serious damage. There is a lot of interest in the hobby, but when they see the professionals, many drop out.


    This is my personal opinion don't get angry:

    To keep enough robots in a class I personally would have no problem trading the Raptor class for a Featherweight Sportsman class. You could then still use your raptor as a cluster for Full combat or the Sportsman class. So all current robots are still usable then.
    I still think that a Sportsman class could mean a lot to the sport.

    My opinion on a few things :)

    Eggbeater vs Drum:

    A featherweight Eggbeater is way more expensive and complicated than most people think.

    You can't put the bearings in the weapon so you need to build bearing blocks.

    These need to be aligned else the weapon generates too much fiction.

    If you have a mill no problem.

    Then you need to build the Eggbeater. The best material for this kind of weapon is Hardox.

    The Hardox must be thicker then the shafts you want to use, mine is 25 mm with 20 mm shafts.

    You need to get the material cut by waterjet with a minimal taper.

    The waterjet company has to cut the material slower and this will make it more expensive.

    If you have a big taper the weapon will not balance well and shake your robot to bits :D

    Then you have to turn the shafts from square to round shafts.

    You need a big late to make the interrupted cut on Hardox and a even bigger late to cut the radius from the shaft to the Eggbeater.

    Aligning is a pain and it you can't do the job yourself you have to pay a lot for this part.

    The pulley needs to be connected to the Eggbeater and should not weaken the shaft, this is already the weakest spot in the Eggbeater.

    All these things make it expensive and harder to build... so be aware.

    Easiest way to build a weapon (in my opinion)

    Use a dead shaft and build a drum with disks on both sides.

    The dead shaft makes the alignment easier and you dont need a mill to make the holes to mount the dead shaft.

    On a small lathe you can make the bearing pockets in the aluminum drum. If you dont own a lathe then many people will do this for you at minimal cost.

    The holes to mount the disks can be made on a pilar-dill. Just create a template on a 3D printer.

    Get some disks, again Hardox is your friend :P

    Make the mounting holes in the disk part of the big hole in the center, this is cheaper to cut!

    The inner hole should be cut with minimal taper, the outside can be cut faster, again cheaper to cut!

    Get some shoulder bolts to mount the disks. Make a groove in the drum and your pulley problem is also solved.

    Don't make this type of drum to wide this won't work well.

    It all depends on what you can build yourself.

    Outsourcing complicated parts/jobs is expensive.

    For speed and wheel size:

    I like 80 mm wheels and 700rpm (minimum) to 1000rpm on the outgoing shaft for both Raptor and Featherweight.
