Hi Doc,

I had the new corsair. Please do a search on JTWILLIE and you will find my write up. Bottom line is I believe the H9 Corsair has a SERIOUS quality problem that must get fixed. The firewall busted loose from my plane the first time I took it to full throttle. This was on the bench when setting the needle valve. Luckily nobody was hurt at the engine left the plan. My hobby shop is in contact with Horizon Hobby about this.
I would wait until they have worked out the bugs.

But it was a great looking finished product. But at this time I would only hang it from the ceiling.

Cheers
JT Williams
