Welcome to the forums! Merrick!

Advice:
you already got it right with the wheels, so that's good. √
instead of pink battery packs, you should use one nifty for this bot.
instead of normal Z-Teks, you should use the HPZ-Teks for drive motors.
DDTs are the way to go when it comes to MW-HW hammers. √
there is a glitch called "DSA" you will have to restart you bot, but it's easy:
all you have to do is when you starting you bot, and you usually click the armor tab, just skip it.
this glitch amour is as strong as steel, and weighs the same as aluminium. im not lying! really! :P
i thought that square extenders were stronger back in the day, but there not.
all they do is weigh more then the other extenders and are just as strong. so don't uses them.
