Re: 360 - mini hypnodisc

thanks alex but I kind of wanted daves (mouldy is a dave right?)view on them
having not been to many events I don't really know peoples names or faces
when I build a feather weight I will know the look of dissapointment on peoples faces as I smash their robots!

so any opinions on these banebots motors (not to hijack your thread of wonderfully machined robots)

Re: 360 - mini hypnodisc

A mouldy is a Dave yes

The video that Alex posted kinda answers your quetion? I'm happy with them so far... I've just supported the rear of the motor just incase.

Re: 360 - mini hypnodisc

thanks guys.
these will definitely go on the list of concideration
720 has amazing speed and torque!
does its drive run on 5s? (sorry if that's a stupid question)

Re: 360 - mini hypnodisc

What motor does 720 use for it's drum?

Re: 360 - mini hypnodisc

In runner - Castle creations neu 2200kv

I believe he is the only person using a brushless In-runner.

Drum weighs about 3Kg, on a ~3:1 ratio giving ~13'000 rpm at the drum and about a 2 second spin up time

This Motor; http://www.robotmarketplace.com/product ... N1515.html

This lipo; http://www.robotmarketplace.com/product ... SPP45.html

both of which ive just noticed have been discounted massively since i purchased them lol

Re: 360 - mini hypnodisc

makes buying replacements better :P

Re: 360 - mini hypnodisc

Galactus uses an inrunner.

Re: 360 - mini hypnodisc

Touro Feather also uses an inrunner to power it's drum.

Re: 360 - mini hypnodisc

Why is it that some opt for inrunners particularly? Smaller diameter? Higher RPM?

I'd have thought the greater torque from an outrunner would be desirable enough to make them steal the show?

Re: 360 - mini hypnodisc

@Megamasher
I wouldn't puy an antweight called 90 on your robot wish list' and post on this thread because it is quite likely that dave m will smash it up.
don't say I didn't warn you

Its exactly that. Drums need less torque and more speed and discs need less speed but more torque. Beyond that it comes down to space and dimensions. In-runners tend to be long and thin where out runners are squatter and wider; hence their different operating characteristics.

Re: 360 - mini hypnodisc

Archie2000, why would Dave M smash up 90?

Re: 360 - mini hypnodisc

Well I know that 99.9% of people on this forum are very nice but
There has been 180(beetle) 360(fw) 540(fw) 720(fw)
I think he wants to complete the family if you get what I mean.
It was meant in a funny way but since I have no sense of humor you probably took it as an offence.
Which wasn't what it was intended for.
