Looks like a better choice than MT now, and cheapter than the GT Pro.
How i wish I hadnt ordered the GT PRO a few weeks back !

I think the $20 you are spending extra on the GT PRO is well worth the money

Why so ? What are the significant advantages of GT PRO over GT ?
They claim that the GT i also full alloy ?

And these are not simple changes for cosmetic reasons.  I find most of these as significant advantages (and that too from someone who basically learnt all RC flying using such helis).
