How much spar cap tape?

[Phil Kriley]

I'm working on the canard, and the plans call for 42 yds of spar cap tape. I heard that some use a little more, so I ordred 43 -

 

Anyway, we did the lower spar cap layup last night and the remaining roll of tape looked small, so we unrolled it and measured it - only 38 feet left!

 

So I just ordered 20 more yards because I figured I sure don't want to be in the middle of the top spar cap layup and run out. I lost count of the number of layers, but I'm thinking 10 or 11 - the first 3 or 4 were full span.

 

Is this typical to need to order so much more?

I pre-measured the roll and figured ACS shorted me about 10 feet on the roll. I called them and since they said the roll should have been enough they FedEx'd another 20 ft. to me the next day free of charge.

 

Here's a tip: If you have a step ladder you can put a stick through the roll and hang the roll between the legs of the ladder.

I've built canards that took two or three additional layers to fill the spar cap. I would have that much extra on hand.
