RE: Hobbico Superstar EP
My 2" wheel upgrade didn't feel quite large enough and the wheels I had found at home were poor quality so I decided to buy some Du-Bro 2-1/2" (250SL) [link=http://www2.towerhobbies.com/cgi-bin/wti0095p?FVSEARCH=250SL&FVPROFIL=++&search3=Go]Super Lite Wheels[/link] with tread. The center holes were too big for my Superstar gear mains so I used some 5/32 diameter round aluminum tubing for inserts.
With my Phasor motor upgrade, it should easily take off from grass now.
