Just a fun thought here. Has anybody thought of using those big old metal Tonka Toys to build a Devestator with? It would be a massive undertaking, but I bet it would be freaking cool as shit! You know what I'm talking about, we all had one or two Tonka construction toys as kids. They were pretty big too and we all had fun playing with them in the sand didn't we? Imagine putting together a G1 Devestator with that! WOW! That thing would be 15 foot tall? Maybe 20?
If you do some digging in the Radicons, you'll find a guy who's attempting a leader class Demolisher out of a Large Tonka esque Excavator.
I don't think it would be 20ft tall. I think they just looked larger to us as kids because we were young/small. http://www.tfw2005.com/boards/radicons-customs/218863-5-g-1-devastator-tribute-v2-tonka-trucks.html Here's one that KINGBOTZ did a while back. If you haven't seen it yet, check it out--it's around 5ft tall.
dont knwo that the guy finshed it but there was a guy doing masterpiece sized constructicons stumbled on it a few months back
