The chassis is 381 mm long 231 mm wide, going to have to make it wider to accommodate a Burkert valve. Everything you see (apart from the motor mounts and legs which are 6mm 6082 ally) will be 3.3 mm hardox. Yep laser cut MDF, smells lovely! There will be also be 15mm HDPE down the sides and back, 3.3 mm hardox scoop, 6 mm HDPE top. Overall 492 x 355 x 133.
Thanks for the responses
Really nice man! Looking forward to seeing this come together!
Impressive. I am still worried about the S900 drive but its your call. I can see you being unable to paint that when its done to save weight! Good luck!
are the s900's heavy or just unreliable ??
They don't make real S900's anymore so they're rare and expensive.
693 g each so heavy but the issue is they are out of production so spares are sparse. I've got a spare pair just in case. The Beauty's use them so can't be that bad :P
They're heavy-ish, and certainly aren't unreliable, it's really just the fact that they're really expensive to buy now if you do break one because they're in such low supply and rather high demand.
That looks awesome! The only advice I can think of right now is to make the tip of the arm out of thicker material as it will take a beating and will be hard to repair if its damaged. The drivetrain looks simple and dependable; what motors did you go with?
Those are the Speed 900's that we are talking about. Originally designed for large model boats like tugs. Very torquey and powerful for a cheap brushed motor... but they are OOP... so spares are replacements are very expensive.Originally Posted by overkill
OK, we have never had motors like that here in OZ. I thought the motors were large enough to be scooter motors. When they break, I'd be looking for a brushless motor from Hobbyking.
