Bird-Of-Prey,
Here's an update on the flight characterisitics.
Most of the flight was done on low rates (low rates throws are set per the assembly). The flight lasted 11 minutes.
I checked the stall characteristics and was very pleased. I pulled the throttle back to idle and applied up elevator. I was expecting the machine to snap when it stalled. To my surprise, the nose dropped and there was a slight, and I mean very slight wing drop. (As of yet, I haven’t checked the lateral balance on the 300 so that may be a contributor).
Next I placed the model in knife edge flight. The knife edge tracked like it was on rails. I literally took my hands of the right gimbal and watch the machine tracking right to left across the sky while only applying rudder. This is the first machine I’ve every flown that locked into a KE and didn’t require major inputs to keep it there.
I wanted to see if the DA 50 would have any issues pulling this machine vertical. It has unlimited vertical. After checking the vertical performance, I put the model into a hover (I’m still in low rates) and it didn’t have any bad tendencies. It pulled out of the hover with very good authority.
I attempted an inverted flat spin (still in low rates). It would spin but I couldn’t get it into a flat spin, even when applying throttle through the maneuver. I needed more control surface movement but being unfamiliar with the machine I want to be very comfortable before I use the high rates. Very happy with the results of this maneuver.
This past weekend I flipped on high rates and the 300 locked into a Knife edge spin with ease. Flat spins are a piece of cake. Just add a little throtte and you're locked in. Hovering is much easier on high rates. Waterfalls are very tight.
Again, this machine is a floater. I really have to slow in down on base before turning onto final so I can loose altitude. I found the sweet spot. A little nose up attitude to loose altitude and just a wee-bit of throttle and the 300 descent is very predictable and since it does not have any tendency to snap at slow speeds, it makes the landing almost mundane.
As far as any build issues with this machine. I didn't find any. I did re-enforce the firewall with some tri-stock and went over the model and checked for areas that could use additional glue. I didn't do anything for this machine that I don't do for others when I assemble. I did remove the ball from the DA50 choke so I could use a mini-servo instead of a standard size servo. Also, since I'm still learning how to assemble giant scale ARF's I installed the throttle and choke linkage as close to the engine as I could.
That’s all folks.
I'd recommend the WH 300 to anyone who wants a solid flying machine, that's built well, and the cost is very reasonable.

On the bright side however, is that Probuild had another in stock, so is all ordered!!! Have to say... an awesome plane indeed!!! Also, the Mejzlik prop. carbon spinner, and 3w 56iB2, and canisters survived unscathed! So, just the bare airframe is needed to get airborne again!
