wish i could say i had good luck with ak models but that was not the case. i ordered two canopies for my cmp texan 160. and since i wanted them in a hurry i opted to pay extra for fex ex instead of regular shipping( 14.00 vs 5.50). i did not get a tracking number so i knew something was wrong. took almost two weeks to get my parts and when i did i noticed it came regular shipping. i called alex to tell him i did not get what i paid for. he didnt call back but did contact me by e-mail asking what the problem was. i told him and sent him a picture of the shipping label asking for a refund for differance in shipping . fair request. that was two weeks ago no calls no e-mails no refund
