剛剛係網上睇到呢段料﹐用 Futaba 控既機師不妨研究下﹐睇下有無幫助﹐我用 JR 控, 所以睇唔明。


The Hidden Secret of OFST

One secret most miss is OFST for Ch. 5 & 6. Futaba only gives 45 deg. flap travel off the throttle stick. Most users, to overcome the lack of travel and obtain 90 deg. flaps, use an extra long control horn on the servo or the hole closes to the flap on the flap horn to get the travel. This makes it almost impossible for the ailerons to line up with the flaps in camber. But using 2 mixers with OFST as master for 5 & 6 allows you to change center of the servo. I would not suggest going past 70% or you will have little or no end point adjustment to balance the flaps later. The best set up is to use the same servos, the same length servo arms and the same hole position on those arms for flaps and ailerons.

The more accurate the servo the more accurate the camber a flap setup. Use End Point adjustment to obtain maximum throw and balance the two channels.

The use of mixers 2 & 3 are just my preference.

In the ADVANCE Menu

Mix 2 MIX - ON
MAS - OFST
SLV - FLP1
SW - C
POSI - NULL
RATE - 0to70
Mix 3 MIX - ON
MAS - OFST
SLV - FLP1
SW - C
POSI - NULL
RATE - 0to70

似乎咁樣set法比較復雜。我嘅做法就用 SUBTRIM 去set 各 channel 嘅中位,然後再用 ATV 去set個 travel range, 非常容易真接了當,個 flap 同 aileron 可以齊上齊落,70 至 80 度 flap 應該冇問題。
