This video documents my build and test flights for a Miles Sparrowhawk built for flying indoors. Extra care was taken to keep the weight to a minimum. The 21 1/2 inch span model weighs 22.10 grams without the rubber motor. Quite pleased with the results. The model was built using oldschool nitrocellulose glue and covered with very light Tuttiro Japanese tissue. Here's links to help you find those items.

The plans I used can be found here, they were reduced down to a 21 1/4 inch span. https://store.flyingmodels.com/produ...
