Multiplex Fun Jet
||I make models are able to fly
fast many time. Because high speed flight is one of my favorites. This
time, I try to
make lighter. Looking for heavy parts in standard setting, I found,
it's motor ! Original motor is
2825-2700. Weight is 135g + "connector about 4g". If choose Warp4 or
MEGA 15/16/x, its weight is about 75g. My choice is "Warp4 2T kv3880 +
4.1x4.1" 430W input power. Pitch speed is approx 210km/h. The Fun Jet
is able to fly over 100mph, isn't it ?
After maiden flight, changed motor TURNIGY
2836-3200 & propeller APC S400 4.5x5.5. The motor is out
runner brushless and max input power 650w. However its setting power is
output 320W, pitch speed 210km/h. Is it enough ?
Of cause My power unit has bigger than
Hitec Multiplex original power unit. 1.8times power and 46%weight diet.
Total 554g weight it is 15% diet compering original weight desigm.
Same company product Micro Jet
, its parts
much better, ex. under cover plastic sheet and linkage
parts. However Fun Jet parts are ordinary one. ELAPOR® is just
foam. I feel
Jet price is expensive comparing Chinese EPO and other foam Jet plane.
But motor mount is very very nice ! It is adjustable down/upper
