Default Best plug in a HPI F4.1

Hey
What is the best plug made by O.S. to be run in a 4.1? I have never been able to get this thing to run right, and I have been using O.S. #8 plugs, as it is what I use in my jato. Is a O.S. A5 or O.S. A3 a better choice? the weather here is 85 degrees and 50-60 percent humidity almost every day. It has always been hard to start and tune, as well as cutting out.
Thanks

I run an A4 plug in mine and the temps around pa right now are in 80s-90s and it runs very well.
