"While the Meng Dr.1 is the Wingnuts plastic, I understand the Meng kit will not have the Wingnuts instructions booklet with it."
Thanks for the confirmation, Dave. I had assumed they would print their own instructions and decals as these would not have been part of the Wingnuts/Meng moulding contract.
So.... I am ignoring box-art, instructions, decals etc and regarding this as a way of buying the complete Wingnuts over trees set for a Triplane at less than half the cost a fully-released Wingnuts kit. I don't think you can go wrong if you approach it this way. If the Meng book and decals are any good it's a bonus! I have three on order from LuckyModels at around 135USD including shipping all-in. So, I can add Ray's book and Pheon/Aviattic decals and still be quids in.
