Hey guys. I thought I'd post this question here. I actually posted the specific question in another forum, and I'm not sure I'll get the answers I'm looking for from there.
Here's the link to my question. It's about engine mounting position, and thrust angle.
[link=http://www.rcuniverse.com/forum/Phoenix_Models_Extra_300S_46_ARF_W%2F_PICTURES/m_2565865/tm.htm]The question is in post #12[/link]

Thanks,
Dan

I would mount the engine inverted. I use an Accupoint incidence meter to set the thrust angles. As for the hole for the needle,just use a small piece of control rod as an extention with a very small hole through the cowl.
