I did look into the Xray as well yes. i have been looking through on ebay at many, trying to find a suitable roller to use a tekno kit on. sadly the xray doenst not have one available. I know its sad to say i want a "easy" conversion, but im kinda looking for a tried true and tested version that will accept the parts i already have and preform well. Now with this being sadi im sure there will be complications but i hope for the best. plus there's a ton of knowledge and builds on here i can always search through if i do encounter bumps.
im not saying that the MBX5t is the for sure it will all depend on the roller i find first that appeals to me and has a good base to build off.
id say,
Xray
Losi 8ight t
MBX5t
mbx6t
rc8t
are all in contention at the moment. Any one have one for sale?
