Something along the lines of 10" x 12" to hang above my desk. reply | | Karl Reese, 30.03.2010 03:24 Where could I find a three-view? Thanks reply | | Ray Cox, e-mail, 02.10.2007 01:00 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. reply | |
| | Simon Gunson, e-mail, 25.02.2007 21:36 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 reply |
