My mail box has been filled with messages saying in effect, now that RCS
has bought all of the assets of Aerotech the motors have to be

I'm looking to buy a new laptops.  Hopefully under $1200, windows,

Any suggestions?

Does anyone here have instructions on how to modify the Estes T25 Centurion
Boost glider to add a .049 engine to it as is claimed in their ads?  Or do I
just throw it on the front end the best I can?
Thanks.
