This is a project plane that I've wanted to do for quite some time. I finally got around to buying an HK Skyfun PNF. I put my ImmersionRC 5.8ghz 600mw vtx on board with a RHCP Spironet antenna. I probably should have just bought the Skyfun Kit because I replaced the stock (cheesy) nylon gear servos with good metal gear servos. Because I have the FPV cam on the nose, I needed extra weight on the back, so I replaced the stock 2500kv motor with a Turnigy 2826-6 2200kv motor and I replaced the stock 25amp esc with a Turnigy Plush 40amp esc. I still need to get a place to mount the Mobius camera but we'll talk about that later.
Here is the finished plane:

I added some serious carbon fiber spars and I covered the plane with colored packing tape. I removed the cheap canopy latches and I added two T-Nuts underneath, at the front and rear of the canopy, and now I use 1/4-20 nylon bolts to hold down the canopy. I am not gonna have the canopy come off during flight.
I did maiden the Skyfun today (FPV gear not powered up). I had a serious case of 'nerves' during the trimming but the plane did smooth out and flew well. I landed, regained my composure and then loaded up another battery for another flight. Full throttle passes are pretty cool with the Skyfun!
I do have a question, though. I was hoping to get some 6x4 APC props for this plane but my local hobby shop was out of them. They did have some 6.3x4 APC Combat props. These props look to be thicker with a slightly different profile than I remember a 6x4 prop has. During the two flights that I had today, the 6.3x4 Combat prop didn't quite have the same sound that I had anticipated. I dunno, I just anticipated a bit more of a sharper, high pitched, sound as the plane flew by.
Would anyone know if there is really that much of a difference between the 6x4 APC prop and the 6.3x4 APC Combat prop? I did speak to the guys at my LHS and they are going to order a handful of 6x4 APC props for me. I'll pick them up and give the Skyfun another go. Maybe I'll get the sound that I anticipated....maybe not, lol.
