speed recording
Hey all,
I am putting together a composite electric speed plane and need to know what is a good way to record maximum speed. I saw one device but it requires drilling holes in wing for air tubes. I rather not drill holes in this beautiful plane. I have heard some do it with handheld GPS units which are accurate but not sure how small they come and probably wont be an abundance of room inside sleek fuse. Any ideas?
Thanks
