Just got my Roboraptor the other day....pretty cool design....so far have had a lot of fun terrorizing my dog with it..lol Main complaint is the speaker...it needs to be beefed up a bit. Amplification is poor...other than that its a home run.

I just got mine and I love it so far--I'm going to be doing some mods on the foot pads to give it a better grip--I'll post my results when completed!

theres some fabric like stuff that u could put on it to make it get a better grip i think its called owl skin or somthing along those lines

modding the robots is half the fun

ya

oh its called beaver skin you can buy it at spoting goods/camping stores.

Ive been hacking the raptor for a while now, with several mods to the head body and tail.
The roar is easy to make alittle louder, if you look into the mouth you will see a perferated plate. this is the speaker grill , you need to open up the head and take out this plate , drill the center out, and it will help a little towards amping it up. If you open up the body the audio is controled by the single transistor on the front of the board. If you look at the pin out names you will see where the speaker goes, hack a small amp from an elec store into these pins , attach the speaker to the amp and louder sound.
hope this helps.
my new site is at sprockets slog
and some of the raptor hacks are here.
