Having experience with large scale electric , dxle 2.0, while amazing, yet my biggest mistake. Had 2 grand into it just to make it dependable...... For the 5 to 10 minutes runtime, 2 to 3 hours of battery charging time with super expensive and undependable batteries I'll never go back. Can run my 2 strokes all day, revo good for 15 minutes but just keep tank full and keep going. X-maxx is different, 30 to 40 minutes depending on how hard of a whooping it's getting. But as for large, 1/5 scale, gas is only way...... just my 2 cents on subject. I think with the 5t clones closing in on price getting close to losi, it's tuff decision on purchasing one,but they are a viable one.
