Flying everything hopefully :)

Flying...all over the place. :proud:
Hi leo V M,
What is the new armour on Hannibalito2 called? We use a similar material to that in work.
That stuff is called High Density PolyEthylene.
A reasonable cheap, light, soft but tough plastic.
im using that in psycho flings new armour and the armour for psycho ram new pictures of the improved psycho ram on my website.

just uploaded a few new pics (same place) of the battery postions, will they get to hot there?
also looking for some new nicads or nimh packs 7.2v, can any one suggest some suitable ones that will run 4 12v motors well?
cheers alex
Hows about pushing the volts a bit?

i was planning on having 2 7,2volt packs, or would one bigger voltage pack be best?
more volts = faster speed
If you double the voltage you double the r.p.m. , double the amps and quadruple the power ( watts )
The downside as can be seen from above....it pulls more amps and puts the motor under extra strain.
BTW ...I was suggesting 2 off 8.4 volt packs ...giving you 16.8 volts.
Itll be a little quicker than running on 14.4volts.
o right i see, yeh think ill consider it
cheers
wont that fry the drill and ur speed controllers aint volted to thast are they?
Electronize will happily handle 24v and the drills should be able to take an extra 4 to 5 volts. I would only get worried if you pumped up the voltage to 24v. This would get a bit risky with drill motors.
do they make 16.8 volt packs?
whats better Nicad or Nimh?
cheers alex
ive onl experienced nicad, i think for 16.8 you would have to have to use 2x 8.4 v packs which i dontt know if they do, or build them your self. personally id get x2 7.4v packs off ebay
i think for 16.8 you would have to have to use 2x 8.4 v packs which i dontt know if they do
Jeez Ant......read the thread.

Alex, as standard they make 8.4v packs, get 2 of these and wire them up as one pack (in series) and use it as one pack as i used to do. And for waht you use/need, use NIMH.
Mr Stu
anyone have a diagram of parrell and series wiring

as woody suggested i thnk im will get 2x 8.4v nimh packs, but what mAh should i be looking at?
alex
found a great site but annoyingly i think its american

The batteries I linked to should ..... I think ...be more than adequate.
Heres the ebay shop http://stores.ebay.co.uk/Vapextech-Batteries-and-Chargershttp://stores.ebay.co.uk/Vapextech-B...s-and-Chargers

will that extra 2.4volts make that much differnce?
also i know thias is basics but on a nicad/nimh charger what does the discharge function do? except for the obvisous thing
alex
Not a lot of difference no.... perhaps 5% faster with 10% more power.
Discharging and Recharging your batteries slowly every so often helps to keep them in tip top condition.
how about these?

Theyre fine.
For notice I think you should really try to research things more/look them up yourself Alex. Asking for solutions to every single point isnt going to gain you much knowledge and I know frustrates the people that answer your questions.
i dont know alot about batterys but what i have learnt mainly dude to woody. I suggest them as a good cheap buy mate, the fact that they show u graphs and tables shows he knows at least somthing about the product hes selling, pm him and ask him questions without the actual unit in front of people its hard to answer certain things good luck
my apoligises ewan, we all have our faults, ill try to work things out more, and decrease the amount i use everyone elses wide bank of expierence
thanks though alex
For what its worth, the whole idea of this forum is to ask questions and gain from others experience.
There is nothing wrong with a little research, but the experience of others is invaluable. Do ask questions. Do think your questions through before asking them.
Thought I would add something in this section as Ive been making a few major adjustments to ploughbot recently.
Specs.
Armour - 4mm hardox, Mild steel, Stainless steel.
Chassis - 100% titanium
Drive - Astroflight 40s, running through custom 15:1 2stage gearboxes. Currently 4wd using the blue wheels, although im now making some interesting changes to this :D.
Batteries - 22.2v, 4500mA Lithium Polymers with 225A discharge (dont think about using Lipos unless you know exactly what your doing with them!!)
Weapon - Lifter with built in self-righting mech. Hardox scoop, down to up in about 1 second. Control for the lifter will also be changing soon.
Speedos - Vantec RDFR23 for drive, making new decision for lifter control.
Weight, 11.1kg.
TX - DX6
Cost - dont ask :uhoh:
Ploughbot evo is still on-going with improvements, and the recent changes in gearboxes, speedo and batteries proved to work better than expected. I now have nearly 1kg to play with and by the UK champs I will have added some other features to bring it a little closer to the limit again.
The new titanium chassis also turned out better than i hoped, saving me well over 1kg compared to the the steel one previously used.
It had a few problems when testing at the weekend, the drive pins need to be better secured and most the problems should be solved to make it more reliable than ever.
I knew my comment would be taken with some cynicism :)
To reassure I obviously dont mean refrain from asking questions at all, but rather do your maths before asking them. The internet is a wealth of guides and pointers which thankfully leaves us people with rather fewer novice questions to repeatedly answer. A comment to be taken with a pinch of salt as always.
Heard many good things of Grants machine, will be good to compete against it come July.

...loosely translates means the drive pin fell out, got carried down the length of the robot by the drive belt and then shorted an un-insulated motor terminal onto the chassis blowing up the Vantec
The master of understatements there Grant ;o)
Only kidding !

Thats exactly what happened :)
Think i got away lightly with the vantec though, appears to be a simple fix - i hope!
Nothing with a Vantec is simple... Trust me on this one!! :sad:
Hannibalito 2 did fairly well last weekend. The power is there, just some issues with control to figure out and because Ed recommended it well think about bottom armour. :)
Leo - I just thought your robot sitting upside down with little hitter pounding seven shades of sh*t out of your drive motors suggested a design flaw ;o)
