Seems we are on a role here!!!!!
Here is a pic of Matney Models Zoomer that died a early death in being sorted out. Not nearly as quick as the new YJ II. Now that I look at both airframes, appears that the Zoomer had some influence on the Yellow Jacket design. In reality, the Q-500, formulas and zoomer are incorporated in the YJ which will hopefully prove to be another home brew knightmare for the local gang. Yes, thats a Viper wing, just cut down to 45". Still lands like a trainer, being CG sorted out now.
