he already has.
now im gonna juse 2 gold motors to power my 4 weels. 1 or 2 HTI motors to power my spinning disk. and SANYO 3600 nimh accus. and make one blok of accu (14.4 volt to power my motors.
is this ok?
I would use 2 HTI motors for the Disc
ok... but do i have enough on one accu, if i power al my motors whit one accupack... (i wanne use an accupack whit SANYO 3600 nimh on 14.4 volts)
I think it will do, if you get the gearing right. The lower the rpms your motor due to a too a poor chosen gear ratio, the more amps you will draw. And with four wheel drive which tends to draw more current to make corners anyway it is very important to keep a good gear ratio.
I dont know the specs for the HTIs exactly but they seemed like high power drillmotors to me. As long as they get the disk quickly up to speed, the current draw should drop quite quickly.
All in all it will be close, but I think 12 cells should do it. Specially since those Sanyos are great cells, they do pack a punch.
While on the subject of motors. I just bought a second hand Astro cobalt 940. I saw on the Astroflight website they are discontinued, anyone know a place where i might find a replacement in case of an emergency?
try team whyachi
we use a 5 to 1 ratio on the HTI for the Disc 6 to 1 would probaly be better they get up to speed very fast about 2 seconds.
According to the Astroflight site the 940 is still listed. http://www.astroflight.com/e/env/store/store-Industrial.html?sid=0001a0PRDdPofIgqdM7S401&link=/store/store-type-tem.html&item=products:af-940http://www.astroflight.com/e/env/sto...001a0PRDdPofIg qdM7S401&link=/store/store-type-tem.html&item=products:af-940
They have changed the design slightly but it is still the same specs.
but my voltage to the HTI motors is 14.4 volts, and kishar juses 24 volts...will 14.4 volts be enough? (my disk is gonna weight +/- 2 kilos)
and sould i juse beld or chain from my motors to my disk. (i planned to juse 2)
