Flown T3 with a 210 and it’s just fine and it’s would never recommend the 310 because it’s to much power. Quality wise I have never met a disappointed customer of a T3. Don’t think I would put the T3 down for quality being they are all painted outside the mold. Both are great planes it’s all about what you want.
people that have them will say which ever one they bought is the best to justify their decision.
