Electric Axe featherweight - first build of FW

[Maxamuslead]

Hey Nat. That Bosch motor you are using where is it from ? As it looks like a Unite Electric 150w Chain scooter motor or are you using it as a stand in.

Which image are you looking at to see the motor? Can you say it's number?
The Bosch motor is a Bosch drill motor in my first design shown in 6563, now I am using an electric scooter motor, but a slim version not the larger round ones most use shown in 6568.
Will find the specs and repost on this message when it's early and not so rainy outside ������
Think you may be right it being a 150watt motor, not sure what modelits from...


MY6812 I guess would be a simularscooter motor, a 120 watt 24v dc motor but will check

****UPDATE****
It's a XYD-15B 24v 10amp motor with output of 135watts.
3000rpm, but will be going through a 5:1 gearbox of gears and belt so that should give a speed suitable for tweeting with the ESC

sorry I was looking at the images 6969 and 6968

this website could help https://www.motiondynamics.com.au/un...ric-motor.html

Also is it a 24v or 12v ?

Been looking for a suitable battery, and Optipower is out of my price range at the moment.
Been looking ideally for a 4S 65c 3300/4000 Lipo and looking on the hobbyking pages i have come across several types that i have whittled it down too.

These being

Turnigy Nano-tech - LiPo - https://hobbyking.com/en_us/turnigy-...lipo-pack.html (not correct C)
Turnigy Heavy Duty - LiPo -https://hobbyking.com/en_us/turnigy-heavy-duty-3300mah-4s-60c-lipo-pack-1.html
Turnigy Bolt - LiHV (assume its under the Lipo) - https://hobbyking.com/en_us/turnigy-...pack-lihv.html

Nano Techs apparently puff up in this application so not great.
Heavy Duty Turnigy are currently out of stock in the UK.
Turnigy Bolts are higher cell voltages than standard LiPo giving 4.35v per cell - LiCo nano tech

Looking at the rules,

Section 7.4 and 7.5 there is a specification that only LiPo chemistry with max cell voltages of 4.2 are allowed.

Where do the LiHV LiPo batteries stand with these rules?

Otherwise, can anyone make a recomendation on a battery brand (i have searched the forums )
Thanks

Where did you hear that? We're using Nano Tech's on our heavyweight....

[Roboteernat]

heard through several posts on this forum - searched for nano-tech however it may differ with different S ratings...

I've personally bought myself some Turnigy Zippy Compacts 5 cell 35C 2700's, and from what I've heard, they're not too bad. And if you look hard enough at that particular set of batteries, then you'll be bound to find something to what you want from that line.

I've had no problems with nano techs. Although I am now running Turnigy Graphene Lipos instead as I needed a shorter/fatter form factor instead of the longer nano tech shape.

[Roboteernat]

Done it, so i now have some 4S nano-tech batteries on their way.
I bought a combat ready 65-130C 3300mah and a tester 2650 60-70c

Edit...
here they are!

Also from their bargain bin sales I got some silicone battery covers for 1p and a lipo fire safe bag for individual battery. This was £2 something.

Cad model redesigned for v3 and I have been able to reduce the square footprint to something more expected, currently cm 40 wide by 30,

Next step is to get some more 10awg wire and fuses for the battery's as per rules, and get a tz85a for the weapon motor.

[Roboteernat]

So, I failed...
Turns out the cheapest place to get wire from was actually hobbyking, so have now bought a lot from them and forfeited the additional postage charge...
In addition to this I have a tz85a and programmer cable, as well as a charging cable for the battery.

Plan ahead of your purchases!

Also I have bought some ball transfer caster units just from China at £1.50 a pop
