Thanks for the info Max,
here is my first attempt at 3d modeling. I made a gif. it is 1.6 megs (I forgot to shrink it down some) that shows the basic mechanics that I am hoping to attempt. The size is 2ftX2ft and is pretty close to scale.

BLACK Motor assembly.
YELLOW pulleys 2 8-inch 2 2inch
RED Drive axels (not to scale)
BLUE Bevel gears(not to scale)
WHITE PVC Leg assembly

no problem...just glad I can help out a bit...the model looks great, I'd say you've got a pretty good handle on what you want to build.

Now you realize, being the first in the community to build such a prop, it's up to you to take LOTS of pictures and write the How-To, that way next year we can say "I'm building a Hibla RC spider."

What modeling program are you using?

GMax it's free! Great program..! people use it to make their own 3d models for video games and stuff.I'm flying blind with this program. but slowly figuring it out. WAY Fun! I think you can download it from here [http://www.turbosquid.com/gmax was freeware!

Ok so after a little more thought I have decided not to go with the 12V power wheels motors. If I am going to spend all my time on this thing I dont want to base it around motors that are shaped goofy and hard to replace. I think that a more accessable motor would be a better way to go. I'm thinking electric wheelchair motors or something along that line.

I had seen a DC motor control switch kit online somewhere .I cant find it now, that controled forward and reverse with a POT. I'm not sure what the range of motion was for the POT.

Are there any good places to look for standardised gear sets? Im looking for steel or aluminum worm gear set to fit 1/2 in sloted axel rod. I think it would be more effecient and durable than the original bevel gears I had thought of first.

actually, they're not.....most of the time worm gears are alot more fragile, and often do not tolerate reversing well

try here...you'd be suprised what you can find at one place

WOW! all kinds of....Stuff. thanks for the link. Yeah after some research I found that the worms have a very low effeicency. With all the stuff at that site it really opens up some options.

I realize this is a super old thread but what happened with the spider? My husband and daughter want a big RC scorpion for our display. It wouldn't be for riding, just terrorizing. Did it work out and if so, please tell me you took tons of pictures and did a how to?

I would like to know if they got it going also. Iam a huge rc person i fly planes and helicopters and something like that be cool.
I know he musta wanted huge but if you only did one maybe 4 ft or so you could just buy a hobby grade rc truck and build the thing to mount to the truck then just drive the truck around. At night most wouldnt notice.

Be cool to put another rx in the bodyand hook up servos to have a 2nd person operating the legs and or tail on a scorpion
