Default H9 F22 Raptor



Thought I'd try this


I have the Grey version with HiTec 625 all surfaces.

She has a Custom Motor mount out of composite and a new OS61FX swinging a 11 * 8 APC prop at 12,300 RPM

Presently she has 5 Flts on her.

Watching her Fly I can tell she is just a tad to short coupled the fuselage really needed to have a few more inches in length for the Speeds mine is moving at.
I Estimate she is running in the 80 MPH range.

The CG at 6" is close to perfect but the Main Gear should have been furthur aft.

Thats my 2 cents.

Next I might put a Macs Tune Pipe on her with a Long Drop and try the 10 * 10 APC.

Seems all the 10" Diameter props actually work very well for the F22 on Take Off.

Is she wiggling her tail in the turns?

I was asked to maiden the RTF version. I was quite impressed with how it flew. It was faster than I expected with flaps locked down and lift enhancement (training configuration).
We did change the prop to an APC two blade because the factory prop lost a blade in his car trunk. I liked it better than the H9 Mustang trainer. It did fly a bit belly heavy when I put it in a roll. The landing approach was super smooth and flared nicely. This plane had a Evolution 46 in it. I bet it would haul a** when you get the OS 60 fx peeked up in it!
