Hi I have too an eco 8 with full option (a little more heavy 100-200g) powered by an mega 22/20/3 and 10 Cell of NiCad and have done a flight with a second pack of 10 Cell as payload for TEST (I Think it's ~ 600 gor more) . It has fly ;) I think it's no problem for embed an IMU board (100g) and an IPAQ + wifi or gprs (300g) ! ;) We 'll see together Jean-Pierre Trammell Hudson wrote: >On Fri, Jul 04, 2003 at 05:26:43PM -0700, Dino Alessandro Gigliotti wrote: > > >>[...] Currently I have one fixed wing .25 sized aircraft and a Ikarus >>ECO8 electric helicopter.
