Hi: The all up weight is around 22 lbs (ish) with the retracts. Retracts are now optional but but for 349.95 you get Air up -Air-down retracts with oleo struts and also aluminum wheels with rubber tires. The retracts we are offering with this kit and alll new planes in 2008 are coming with all new generation of retracts. If you buy the airplanes with the retarcts at the time of the original aircraft purchase we offer a combo special. Please ask your LHS to bring one in for you or if there is none in your area we can ship you direct.
