Gratitude good sir 8)

2 pounds sounds much more reasonable, I must have misread that in another thread. I plan on using it in a large ornithopter setup with belts + pulleys for the primary reduction stage and chains + sprockets for the final drive. The setup of these components will be similar to ones used in modern...

Touche, thanks!

25:1 isn't set in stone but is more of a general ratio I'm thinking around, I must state that although my project won't actually be an ebike but will incorporate similar mechanisms for the 80100 setup bikes. Mounting space will be on a 3ft x 1ft piece of aluminum so their will be plenty of...

This carbon belt seems superior to conventional belts or chains. It's much stronger, requires no lubrication, very durable towards the elements and is noiseless. Has anyone ever incorporated one of these into one of their ebike projects? zekA4fK7aKc

What is the lightest 25:1 gearbox, or variable ratio gearboxe, that is a good choice with the Turnigy 80-100-B?

Can anyone explain what kind of applications would use or benefit from this type of reduction system? What is the reasoning to go from a belt to a chain and what benefits does it entail?

The link I posted was the only existing page that had any info on the Predator 50/6 and it was very limited. I just got a response from a Plettenberg employee and they said it is for sale but that they do not have any data online, likely because it is rarely purchased I would assume. It seems to...

Someone must have knowledge on these motors!

After being impressed by the power of the Predator 37 http://www.plettenberg-motoren.com/UK/Motoren/aussen/Predator37/Motor.htm, I came across the Predator 50/6 http://web.mac.com/goransson/Watts_up/Blogg/Poster/2011/6/13_PREDATOR_50_6.html. Is this a large upgrade from the Predator 37 and do...

What are the features that really set apart the brushless motors in the 15-20kw range such as the Hacker A200, Predator 37, Joby Motors, etc. Is it the Kv that makes a large difference? The Predator has a unique design that allows better cooling from spaces in the center of it, other than that I...

Jarnos has 13 videos in total on his youtube account showing the process of building his mechanism, they are definitely worth a look. I feel that your estimate on a 10kW motor is promising seeing as how Jarnos design only used two 2kW brushless motors. That makes sense that a lot of the power...
