Where could I find a three-view? Thanks

As this aircraft clearly has a horizontal rear stabilizer, I suspect the stub wing at the front provides lift, making the ATTT a Tandem-Wing aircraft.

I notice the canard has anhedral and the main wing dihedral. I take it therefore that this is because there is a real risk of the front wing interfering with or blocking airflow to the main wing ?
Also when Mt Cook Airlines in the 1980s used BN Islanders as skiplanes in New Zealand they found the attachment of undercarriage to a very rigid wing structure caused wing spar cracks. Is this aircraft going to be tested/evaluated for this type of stress ? -Simon Gunson
Do you have any comments about this aircraft ?
