Re: scruffy

You can also get the same Rx at Hobby King. http://www.hobbyking.com/hobbyking/stor ... lsafe.html You will have to check if it is still cheaper with postage.

Re: scruffy

out of interest does anyone know how thick the steel is on old calor gas bottles and weather is better grade steel than general mild, because i was wandering if it would make good armour or i could use a chunk to make a scoop for a robot

Re: scruffy

I don't know the thickness, but if you search calor gas wood burner or similar into Google images you get lots of results showing sliced up bottles. You may be able to gauge whether it is worth cutting one up from any pictures showing the steel side-on.

Re: scruffy

from what i've see it looks around the 2-3mm area but i'm not sure

my dad has 1 that's sat in the garden for years which i'm temped to chop will need to fill it with water first to make sure there's nothing left in it

Re: scruffy

I'm my experience they have a 3.5 / 4 mm gauge. Before you cut it unscrew the valve

Re: scruffy

good to know, have a design that can use the curvy shape of the bottles


also i have just done a quick test with the a lipo in my 4wd bot and it seems to make a hell of a difference i had it off the deck and compared how how fast the wheels moved and how the motors sounded and the wheels were definitely moving quicker and the bec didn't cut out when i changed direction quickly as the was plenty for all 4 motors

i also might have to upgrade my power splitter as it probably cant handle the new current when pushing so the might melt but at least they wont short so when the weather dries a bit i will take them to the basket bell court and see what i can brake when with the new upgrades

Re: scruffy

ok gave scruffy another test drive and still a pain with the steering so i tried my dx3e and it now seems to drive better in a straight lign and i can control its turning speed , so it seems to be driving better

Re: scruffy

ok scruffy seems to working well and now everything failsafes when i turn the transmitter off just have to tidy the wires up and re enforce the lifters scoop a bit so it will soon have a nose

and my 4wd bot is just awaiting for 100a fuses to arrive for the lipo pack and then i can give it a proper test to make sure the wires and power splitter is up to the job

Re: scruffy

ok bit of an update

finally got round to cutting some of the material for my new drill powered lifter bot, i have cut the 100mm diameter tube in half and put a slight angle on either side, so the back end is done i also cut the side panels but still have to make the front panel

i have also started to order bit for my latest 4wd bot which im aiming to put some character into it a bit like scruffy but with more detail and it will also have a weapon

[plargen]

Re: scruffy

ok bit of an update

I've tack welded the side plates to the back end of the bot still have to cut the front and top plate and trim the aluminium base plate down to size

im also now building the lifter mech into the top armour instead of having a supporting frame from the base plate


the structure so far is 100mm dia tube 4mm thick sliced in half at the back with about a 16deg angle on either side, the 2 side panels are made out of 3mm mild steel, the front pannel will also be the same and the base plate is 6mm aluminium which might be a bit thick ?

[plargen]

Re: scruffy

ok

I've welded the armour together and fitted the base plate next on the list is making the top plate which will be 3mm steel which i will mount the sprocket and bearing and drive motor, the motor puts out a max of 36nm at 400 rpm and the chain reduction will be will be 6.33 to 1 which will bring to to 63rpm (not accounting for any resistance)

the lifting arm will be about 250mm from pivot to tip, so if my calculation are correct (and please correct me if i'm wrong) should give me 90kg ish at the tip


Im also going to make the end of the weapon interchangeable between a lifter and an axe as the drill motor is a 2 speed so i have the option between 400 and 1300 rpm and the drill give out 20nm at 1300rpm

Re: scruffy

Looks very neat so far
