[Johannes.Laubenthal]

Hi !
Rebel 603 is ready to take off. After nearly 3,7 years my Rebel is finished.I
bought the kit in Epinal France december 1997 from Brian Godden. It has a
springgear ,Lycoming 0-320 160 hp ,Lasar Ignition System,Airwolf filter system,
Warp 4 blade HP Prop 2 inchs massive aluminium prop-spacer,Insight Gem
610,electr.Turn&bank,electr. Attitude Indicator;VDO Motorinstr.;Icom
receiver,King Transponder,and a Flightcom System (german Ultralight scene).A
german Varta Gel Battery 12V 40Ah weight 30 lbs is movable mounted in the
tailcone also ELT fix.My empty weight is 1017lbs CofG 13,3 Inches battery in
most backward position.After modification of the brakes Rebel R 603 taxis very
nice (the Fixed plate BRK-6 touched the 7/8" Extrusion BRK 13). In order to get
the allowance to fly the german LBA (Luftfahrt Bundesamt equivalent of the US
NTSB? )wants a Loading test of my rebel to check out my assembling quality
,skill,kit qualities ?? :-( :-( By the way it will be one of the first flying
german rebels.
