THE VEKTA IS A BEAST!!!!!!
I want one...will probably be my next buy...but for you... with the racing thingy....I think a few thnigs come into play.
-First off, the DBXL and the Vekta cant even really be compared to each other...the Vekta is on this level the DBXL isn't even close too. Im not downing the DBXL, i own one, it is what it is, and what its NOT, is on the same level as the Vekta. Build materials and quality out the box doesn't even come close. Vekta wins that one, hand down.
-Whats your budget?
-Do you wanna race just to race or do you wanna race competitively and win?
-If you have the money for a Vekta ($1500-$2000) you could get a DBXL ($1000) and upgrade the hell out of it and have a beastly machine.. or consider the Losi 5ive t or 5ive B...aftermarket support for both is already established and they are both racing platforms.
-For that kind of coin you could get rollers and upgrade them to be exactly what you want/need them to be.
-Vekta 5 looks like its gonna handle better in rough terrain.
-The losi 5ives and DBXL may handle better in everything else....lower center of gravity...less roll..etc.. There are guys getting podiums races against 5ives with the DBXL
-The DBXL has some issues with the driveline and shocks but both are upgradeable and still would come in costing less than a Vekta with a motor.
-Vekta is 38lbs WITHOUT a motor...gonna need AT LEAST a 32cc w/pipe to make it move. Same motor in a smaller RC would have a much better power to weight ratio....but would probably start breaking things on the DBXL drivetrain....which can be upgraded.
