Hmm...Ive had a look on Google and not many pages have astroflights...but these graupners sound pretty good too. Ill do my research on them.

Does anybody have a link to astroflights that can be used in a feather?

I would go for 12v gold motors with a chain and sprocket drivetrain.

You can use electronize as said earlier and you only need a single 12v battery. Remember that more powerful motors require not just bigger speed controllers but bigger higher quality batteries.

From what I have heard astroflight are a pain in the proverbial to deal with.

hey kody, you are in Canada right?

TWR18 with whyachi wheels.
perfect for what you are wanting, less powerful than astros, but very nice still.
cheers

Dewalts IMHO are a much better motor in terms of price and performance.

Why pay USD$160 for an Astroflight motor (no gearbox etc etc) when you can pay USD$165 for a Team Delta 18v Dewalt kit with motor, gearbox (2 speed), CNC mounts and output shaft.

The Dewalts have a great range of spares from easy to access places like Dewalts Service and Part or the Robot Market Place. IIRC, Astroflight 940 motors are no longer available in combat models (They still make boat/plane ones I think) and you have to make your own custom gearbox which is even more money...

Weve had some very sucessful rambots here in Australia using Dewalts.

Just my 2c :proud:

I use Astros for the weight. They are very light for the power they give out, and i dont have enough weight spare for anything heavier.
Astroflight 940 motors are no longer available in combat models????
They are still astroflights main industrial motors. I just bought another batch a couple of weeks ago.

are these any good?

and is the $149 price for both sides?

alex

James, I like the TWRs. They seem really good for the type of bot I want. :)

alexander I cant comment on quality however I believe it to be high but you have to buy the $149 is for a single side module and then you have to buy your motors on top of that. So if you were to go for two along with two s28-150 magmotors (as an example) then it would cost $298 for the modules plus $598 for the two motors plus shipping and probably plus VAT when it arrives of 17.5%

Not as cheap as it first appears!
