Thanks for the positive comments my first Covit project, we are now in lock down so no chance of testing it now.
I have had time to make a few changes though, steerable tail skid, bolly prop which gave me an extra 1 kg f thrust and made a jig to balance it properly.
Lots o 3d printed parts on this model, wheels, guns, pilot, cover plates windscreen etc.
I am confident it will be a better flyer now with the extra thrust.
