Hi after the first fly of my pitts special with one of the cheap £20
brushless sets from al's models ,its to underpowered I have tried the
recommended 10X4.7 and 9X4.7 and a 9X3.8 apc slow fly props, with the
current setup its just over 400 grams with an 1800mah LiPo 11.1v pack
it fly's just like a trainer not like a pitts do I need to get motor calc or
similar to work out a better setup or could somebody recommend a similar
motor set up that will pull this plane vertical for not much extra weight

Not nearly enough information.

And little details like wingspan, area, and battery back would be useful.

as its supposedly a 3d model and supposed to hover 1/2 throttleI thought
weight was the limiting factor rather than all the dimensions or am I
barking up the wrong tree?
but from the box its a pitts special bi-plane with wingspan: 710 mmLength:
660 mmWing area: 24,8 dm² Airframe weight: 300 g Surface loading: 12 g/dm²
and as soon as I remember my password I will post in rc groups
