I just saw them again, yeah that’s funky
What if you remove the broken stuff and attach a new ear to the case? A metal L comes to mind epoxied onto the case
I don’t think even the epoxy will hold it as is in the long run

Yeah I was considering screwing a 90 degree bracket onto it with the screw heads being inside the casing because the camera is raised by a couple of small ‘lips’ (for lack of a better word) to centre it (there’s a pair on each side of the case). Which means there is a gap for small screw heads.
My main problem with that approach is that the body might not take a lot of punishment, it’s only 1mm thick polycarbonate. Granted, polycarbonate is strong but I’m not sure how a flat surface will deal with all of the impact on the camera.
I can run some tests on my old bodyshell though.
Is that Plastic kinda thing or thremacol kinda thing?
It’s a tough type of plastic. It’s more of a compound, light a pretty strong. Sometimes called Lexan, but I think that’s a brand.
Oh. Okay…
This isn’t a project but last night I was tearing down some of my dad’s ancient power tools that he hadn’t used in years because they were rubbish (apart from the one Bosch I tore down). They seem to be a decent source of 18V 550 brushed motors. The only issue is that I can’t get the pinions off. A friend suggested penetrating grease and a blowtorch. I don’t have either of those but I might give it a shot some day.
I also tore apart my dad’s old 24V Bosch to see what was inside. The motor was a beast. It was 70mm (can length not including the pinion) by 48mm (diameter) compared to the 550 which is 57mm x 36mm.
Some 1:10 scale RCs use 550 size motors, Banshee and Hellhound use 540 size motors. However, Banshee has an insane brushless setup so it will annihilate these in speed. But they win in torque. Unfortunately I can’t use the 24V one because 1) the drill actually still works (the 24V battery is totally dead but some 18Vs from another Bosch work fine on it…for now, they’re close to death too) and 2) I don’t have an application for it.
The 2 crappy 18V drills I took apart seemed to be from the same OEM. It was my first disassembly of a drill gearbox; the contents were pretty interesting.
Going from the motor to the bit holder:
There’s a plate with a hole in the middle for the pinion to go through, the plate is part of a clutch system which I will explain in a moment. The pinion meshes with 3 planetary gears which are inside a ring gear. The planetary gears are on shafts which are connected to a plate that has a pinion gear on the other side of it, this meshes to another layer of planetaries (which are bigger than the first set, I’m assuming for torque multiplication). These are also inside the same ring gear.
The plate that the second planetaries are connected to goes to the bit holder. In the base of the casing there are 2 layers of balls around the final planetary plate. How much these balls protrude determines how easily the clutch system slips (it’s for torque settings). The protruding balls determine the ease of slip because one side of the ring gear has triangular points or teeth which push against the balls sideways when the drill spins, if they are lower, the teeth will go over the balls more easily. The other side of the ring gear is pressed against the plate at the start.
I didn’t think to take a pic of the other side of the ring gear, sorry.
Went for another run with Banshee today, the only real damage today was that the motor fans took a beating. I’m planning on replacing them with ones that are actually big enough to fit the mount, these ones are too small and can only be mounted on 1 of their 4 screw holes. At least the current ones were cheap (they were somewhere under £5).
In other news, the superglue did not hold at all. I went over a sharp pothole and the camera just came right off. I’m thinking of using a bracket as opposed to epoxy @framos1792
On the topic of the camera; I need to find a lower mounting point for it because it throws off my centre of gravity way too much (I kept cocking a rear wheel even in medium turns). The near crash in the first gif was caused by the camera being really high up, when it broke off again I was able to chuck it into bends far more viciously and it took them almost perfectly.
Oh how nice, you were out for a run today and the vids are just great… it looks like banshee runs very fast today, and I don’t know if it is the perspective but you look taller and more slender - the crash is spectacular as always - thanx for sharing
The speed is down to perspective, yes, also the fact that there was still some light left and I was over bumpy terrain. As for me, I’m the same as before. The crash was totally rubbish, it wasn’t even a crash; the truck to the bump just fine, it was just the camera that dropped off and tumbled away. I had an off camera one after a wheelie that was a bit better (the one that battered my fans).
I like the bracket idea better too
Can the camera fit through the “windshield” if you cut it open? Lol it would be nice and low? Held onto chassis or some other part under as opposed to the body
I was considering mounting it behind the windscreen but the two main problems are that I don’t think I have enough internal space and that the light bar is in the way. Also cutting a hole in the windscreen is going to affect rigidity quite significantly as well as waterproofing. I’ll see if I can mount it between the light bar and the windscreen.
With a bit of luck I’ll start on the wheelie bar next weekend.
Ouch at that last gif
Or maybe buy a lighter camera. What camera do you use right now?
Nothing much happened, the camera literally fell off the truck, the truck just went through the hole.
I use a cheap go pro knock-off I don’t want to spend another 40 on a camera though.
Look like bansshee had an amazing run today look really fast too.
The run was 50/50, I had fun chucking it into bends once the camera fell off because the centre of gravity was back to normal.
Oh haha, looks like a heavier accident.
Yeah those cameras are already one of the lightest there are.
Yeah, it’s just a matter of perspective, you can test it by setting your phone to record and then dropping it on your bed with a bit of a spin, it will look far worse on the footage than in real life.
My one is probably a tad heavier than a real go pro but I have the suspicion that the casing is heavier than the camera itself.
Looks so cool with the lights
Yeah, this is an older pic, before I added the 4 new ones. It was the only one I could find with a good view of the camera.
Looks like the damage to one of the fans was more extensive that I initially though. I’ll be upgrading to better ones.
