I made the 3 holes like oval shape.. Also change the button head bolts in the tail clamps they strip easily especially the one inside the tail where you need to tighten through holes in the side... I also added a fan in front of the motor to help with cooling...

I have the Life Saver model, and found i had to sand a bit of the hole for the boom and sanded the curve on the fenestron tail blades at the trailing edge at full travel so they have less chance of hitting the edge of the tail duct , may have to put washers or a plate under the mounting brackets.
