Is it safe to use more than 50% H2O2 mixtures

Team ARCA (http://www.arcaspace.ro/) just posted about about a successful
test flight of thier prototype. Of interest to me it is mentioned that they
use 60% and 68% peroxide mixed with alochol and seem to have little problems
with getting thier motor started. Is this high a percent peroxide safe? Do
they mix in less alochol to keep it safe?
Do you think that Armadillo's motors would run better with a higher peroxide
percentage? This is the first time I have heard of anyone using a mixed
peroxide with more than 50% peroxide repeatly.

Mixed pure peroxide and alcohol is a powerful explosive.
You need the water there.
