I have yet to see a positive story come out from one of these gassers, both of these companies need to have a long hard look at themselves and the product they are selling , why put it on the market when the failure rate I so high.
when I was in the market for my gasser I looked long and hard at both trucks , I chose the octane because here in oz losi and especially the xxl line is not very well backed and after being a traxxas man for years I thought I should give the opposing team a shot. truck itself cost me $1059 and after the first tank I was not happy with many things , the engine was sweet but the rest of the truck was crap. I would say I have spent close to 2k on the truck and upgrades and now its a better truck , not my favourite but still, after 12 tanks it needed a new engine due to no compression , which was eventually replaced under warranty nearly 3 months after the fact , partly due to my lhs's inability to follow thing through and I ended up sorting it out with hpi Australia directly and putting the truck back together myself I was really unhappy with the process altogether.
I really hope you get a new engine from losi as the amount of money we are shelling out for these trucks is silly for it to be sitting on a bench in pieces...
