Tarantulator is very slow! It needs to be faster to be interesting in using it!
Or could it be a bug here?

Thanks

the reason it is slow is because you can fit 7 exo legs
the normal one can only use 3

Even with 7 exo legs he is still slower than spidertron with 1 exo legs. :(

Tarantulator with 7 exo legs is about the same speed as Spidertron with no extra legs. The wavy movement it does after travelling in one direction for a while might be wasting some of the speed from the exo legs.

Changing some numbers in data.lua helps with the speed. The longer legs get a movement acceleration of 0.25, and the short ones 0.025. This makes the Tarantulator veeeery slightly slower than a Spidertron with an equal number of legs, and also preserves the unique leg movement and a tiny bit of the wobble.
