OK ! TIME FOR A WHINGE FEST !!!
I received the SK3 motor today , and when i looked at it i wasn't impressed , the outrunner casing has a spigot where the stub shaft bolts onto the casing and 4x 3mm tapped holes !!!! these 4 holes are equally spaced on a radius around the spigot , the problem is there are 5 cooling vents in the casing , which means 2 of the tapped holes comes very close to the vents ( poor design ) tapping it out to 4mm isnt an option .
the thing is this motor can swing a 22 inch prop @ upto 4000 watts all on 3mm bolts tapped into aluminium less than 3mm deep , combine this with the fact the shaft is only 8mm diametre and it's hollow !!!! adding further the stub shaft recess is too small for the spigot , they wont mate together without a mod !!!!
on the other end of the motor where the mount plate fits , the bolts are 4mm !!! and not helicoiled like they advertise , this is a heavy motor which needs to be spaced farward from the firewall !!! which will compound the stress on the 4mm bolts .
for a motor of this size , which is marketed as the next step up from HK . i'm dissapointed upon inspection . to me it is poorly designed . one prop strike will probably cause a lot of damage .
rant off with the motor .
now to rant on the K'FORCE ESC 120V . this version has a spark arrestor with 5 capacitors between the 2 battery leads dangling off wire cables about as thick as the hair on my balding scalp . nough said . remember this has to be fitted to a 3d aeroplane .
cheap switch ! bought the only switch in stock at the hk ausie warehouse , heaps of comments about failures with this switch as its a single rail switch , looking at it i strongly agree , i bought a few switches from jaycar to use instead , which means a lot of wring and soldering in the GARAGE !!
CAN ANY ONE TELL I'VE JUST WOKEN UP FROM NIGHT SHIFT ?
Yeah i guess your right GAZZ . IT'S WRONG TO ADVERTISE higher quality than standard , as you can see the bearing in tho motor will be good for a go kart wheel , yet the the 3mm screws swinging a high rpm large prop .
did you imply that i could remove those 4 capacitors if i want from the ESC ?
