RE: 86 vs 85 Fuse length
Hi, Not sure on the length being shorter but my QQ 86" flyes perfect with no bad habits. Both planes are grade A planes. My friend has the EF with a DA 50 and loves it. I also have a DA 50 as well and love the combo.
If i were you i would decide on what color you like best and qo with it.
Hope this helped.
