Hi da Rock: "Are you really going to use just washers" No, I just said that to show how downthrust is a easy fix to my problem. If I do put in downthrust I will make a tapered shim so all of the metal mount flange of the motor sits flush to the firewall.

" Since your model is going to be significantly heavy " Actually , I thought I did very good to get this kit at 27 pounds all up flying wieght ( without fuel ). This plane has full detail, fiberglass, paint, panel lines, full cockpit, full pilot, etc. So for a TopFlite kit I think the wieght is ok. Sure, an ARF would be much lighter and a TF kit that was just Monocoat covered would be lighter, but I am used to the higher wing loading.

So it sounds like you think downthrust would be ok. Thanks for your reply
I will make the shim removable so I could try the plane both ways.

Hi, thanks for the note on the 2+ degrees down thrust.

ThunderBoat42: The plans show no downthrust.


I may just experiment, although I would like to hear more about the subject.
