It's obvious from some of those kits that the designs were meant to be 1/16" but 1/20" was substituted to mitigate heavy wood.
It's alright saying that you get more accurate parts by cutting them out yourself, but when you take some of the kits you throw the rubber, the prop, and the wood away, all you are able to use Is the canopy, the wheels and the plan so why bother? Where's the value?
The laser cut kit of the beaver I bought is super, it's not the lightest wood in the world, but it's good when compared to the price of the kit and all of the other stuff you get in the box. Out of that kit the only thing you can't really use is the rubber - I wish they would sort that out too!
The little 900 series bird dog will be a real winner when they laser cut it.
