Joe,

what catracer said. But are the cores cut with a flat front or a sharp LE? Either way, it works out best to have a balsa LE from a construction standpoint. So sheet, then cut back and sand. It is also easier to fix a ding in a piece of balsa than in a sheeted foam LE section. Use the lightest 1/16" contest balsa and laminating epoxy for sheeting or some good 1/32". I'd go 1/32" - everything about this design tells me it ought to be 3.5 lbs but back in the day everything was built much heavier...

If you make a sketch of the wing and stab core planform with dimensions and trace the root and tip airfoils, I can draw up a set of CAD plans them. Something like the drawing below which is in progress (this one is framed up of course).

You will like the 32F's - true ABC engines. I can't pass them up, just picked up another recently. The Webra's with TN2 carbs are nice too although I haven't run one yet. I hear that they can tend to spit fuel a bit but I'm not sure if this is a carb issue or a front end design issue. I have a 32 with a Dynamix carb and a 25 with a TN2. I plan to test them with each carb. The TN2 is probably easier to set and might transition nicely. The Dynamix probably has more top end power - it has a larger throat. The 32F's are a good solid engine though.

Thanks for the pics of the plans. I'll take a look at them in more detail during the day.

David.
