The flight performance of the Firstar has been very disappointing, mainly I think because of the effect of the negative thrust angle which effectively just increases the wing loading.
So, like I'd long considered with the Floater Jet but never actually did, I've replaced the pusher prop with a low-mounted 70mm EDF installed directly on the body mount used for the stock motor tower with large cable tie straps screwed in place.
The EDF is rated at about 1.2kg thrust, far more than required, so I'm only running it at 60% speed on a 3000 4S lipo, which is more than adequate. In conjunction I've also replaced the stock 30A ESC with a 50A unit.
The thrust line of the EDF is virtually through the centre of lift on the wing, and this shows on launch with the V2 flying straight and then beginning to climb as the speed climbs, in stark contrast to its behavior with the tall pusher prop where it always nosed in and was reluctant to climb.
The much sleeker form, with the tower and foam shroud, means that it's also faster through the air, if required, and glides very well. And, if you needed more benefits, it also sounds brilliant...
