On the 1.80 I have been tinkering with mine. The APC 18x6W on 15% nitro is a little week. It does not give me the spool up I want. I have a wood Zinger 17x8 on it now and it's pretty good. I have a Zinger pro 18x6 to try and a APC17x6 to try. The 18x6W is just to heavy. 30% would bring it to life and I may end up there. I am just not ready to do that. I was hoping to find a good 3D prop on 15% fuel.
