KR> Speeds

[Doran Jaffas]

Hello Everyone
   I've read quite abit about expected airspeeds. Some contradicting each
other.
   Depending on the engines used there seems to be quite a variation
   My question is simply this; On a stock retractable gear KR2 what is the
maximum safe continous safe real world operating speed assuming a properly
built aircraft?
     May have been already asked so feel free to point me in the right
direction.
           Thank You
