Mr. Thang built all these or at one time in the past, the owner of all of these.
He gave me the BD-5 (lower right, placed ontop of the Flybear which he also gave me).

I hot-glued my WLToys receiver board, glued back the 0720 motor (he did the changing of the motor wires), loosen and rebind the pushrods (his receiver was linear type and mine is rotary, so the wire right angle and keeper in the pushrods were 90 degrees out), put in 260mah Turnigy (he bought for me from HobbyKing) and had many good flights yesterday.

He's a sticker for 7mm, I am a proponent for 8.5mm. It flies ok in the still air early in the morning, but when the wind became stronger, it was not so easy to fly. I find the 7mm is barely enough in that condition. In still air, I could be puttering around at half throttle, but in windier condition I was on full. The throttle response is just not linear for these small motors. The difference with 50% or 100% on throttle stick is marginal.

It can't loop from level, even an initial dive is not enough. I find that the model is draggy, losing airspeed very quickly, and this model needs to build up airspeed otherwise it stalls. In windy conditions, I could not bring the model high up, a definite sign of insufficient thrust.

We consulted and while I wanted to use 8.5mm motor, but since the 7mm motor is already glued in, we thought we could try to use the 65mm prop  that I brought to the field. He thinks the 65mm will be too much for 7mm, I tend to agree but we are game to try. He cut off the nose cone of the 65mm (he has a sharp knife) and while pushing the prop onto the shaft, the motor innards got pushed into the model. Now we have to try 8.5mm. Decision has been reached by events.
