Ok so my trex gasser is almost ready for flight..There's a couple things that I'm not sure of..First of all it has a trex 800 tail boom with a three bladed tail with 107mm blades....The main blades are 710mm....I figured with the 800 tail boom there shouldn't be a clearance issue. . But looking from the side it looks like the will hit..Do i need shorter tailblases or main blades

I think that will miss but I would have thought there would have been more clearance than that! Are you sure they are 107mm tail blades?

Just push down on the tip of the main blade to see if you can get it to touch a tail blade, don't worry you won't break anything.

60% of the time, it works every time!

The 700N DFC has an extended boom (extra 15mm) for main blades up to 720mm.

Given you have a 800 class boom, 710mm mains and 107mm tail blades, you should have no worries at all.

Another option for "clearance" check is with a piece of string taped off the tip of main blades and something tied to the other end for weight (a.k.a. plumb bob) It will take a few turns to find angle where tail blades will be closest to string.

That looks better than my 700 with 710 mains and 105 tails. I have never had an issue. Lots of autos, no boom strikes.
