After looking at it, It looks a lot like my Super Taiji .40 from Airborne models. I don't know the kit quality of the Oasis, but it looks like it would be a good pattern plane and the price is quite reasonable.
On the other hand, You usually get what you pay for, So it might take some finagling to get it all together. I'll inclose a link to the Super Taiji from Airborne Models. This is a quality kit and it flies well. The only thing that I would do different If I were to build another one, Would be to put the El and Rud servo's in the rear of the plane, To help achieve the C/G as the plane comes out too nose heavy with the El and Rud servo's in the front. The Oasis already has this set-up with the El and Rud servo's in the rear.
