Well, after THOROUGH investigation into all the motors that would work in the Xmod....I found out that the Megatech 21T engine will NOT work in an Xmod without adding a turbo ESC/Fett upgrade which I'm sure can be done, but have yet to read the docs on the mini-z sister site to tiny-rc. In fact I emplore you to REALLY review all the info you can on some of these mini-z motors before plopping them in your x-mod because a great# of these REQUIRE the turbo or else its "pop goes the ESC".
now the GOOD news.
I read a lot about that NML guy and it seems he's on the up and up and people love his stuff.....plus according to another post here, he's dropped the price from $60 to just over $30......
Gonna go try the Stage 2 yellow I just stuck in there.....
Anyone with the X-speed motor installed want to comment on if they're happy with it vs. Stage 2???????? B/C $30 may still be just a bit pricey for me......dunno will do more research...
