MODEL: Sunriser
DESIGNER: Jamara (germany)
DATE: 1995-ish
WING SPAN (in): 97.5
WING AREA (in^2): 608
AIRFOIL: Eppler 205
LENGTH (in): 48.5
AUW (oz): 48.5
W/L(oz/sq-ft): 11.5
POWER: turnigy 2830 motor with (I think) 10x6 prop
NOTES: Very nifty twin boom design (nifty but fragile). This was from an ARF kit w/ some mods to wing joiner areas for additional shear web/strength. Per the notes on the manual: “The well-known record pilot Dr. Hackstein, set two world records with a flight time of approx. 10 hours and a distance of 240 km”. Modified fuse for brushless motor. Larger than necessary 3S, 11.1V, 2200 mah lipo and 4.8v, sub-c 3600 mah receiver battery - I think because it was designed for large NiCd battery needed the additional weight in the nose to get proper CG. Original RCM, review published AUW was ~50oz so not too far off of that.

WING SPAN (in): 118
WING AREA (in^2): 1470
AIRFOIL: Flat bottom (~10%, est), max chord = 12 inch
LENGTH (in): 51.25
AUW (oz): 77.2
W/L(oz/sq-ft): 7.6
POWER: Great Planes AMMO inrunner 28-56, 3200kv w/feigao 380 planetary garbox (unkown ratio – maybe 4:1). 13x7 HK CF prop and 36mm diam aeronaut spinner w/ 4mm collet. I have no idea what the gear ratio is on this planetary gearbox, but it seems fine.
NOTES: RES w/ wings per Plan and modified fuselage for electric pod/boom. Initially built fuselage per plan but was super –dooooper tail heavy so rather than put a half ton of lead in the nose modified with rather heavy geared motor and carbon fiber shaft boom.
