Looks like we are defining it differently...
Looking at plans from Dave Patrick, Miles Reed, Bob Godfrey and others, they all have positive incidence in the stab... and usually 0 in the wings... the right thrust suggested varies, but the down is usually 0 too...
At any rate... built as is, it's a fine plane... but it will most likely balloon under power...

hmm.... maybe we are defining "ballooning" differently. I consider ballooning to be a sudden jump upwards under power. My miniplanes did climb under power, but that trimmed out with thrust adjustments.
