| Why not going for 2 cells ???Based on my current infos, I think that I really prefer going with the “standard Rx” route (AR6300) than the 1 cell convertion for the 4-1. This will allow me to use my curent Graupner "big programable' Transmiter.
But before I do this, I still have one question: What is the real advantage to go 1 cell rather than 2 cells.
In my understanding, the 2 gr weight advantage on the battery ( 11 gr for 1s400mA instead of may be 13gr for 2s 220 mA) really don’t pay for the complication on the Rx'sconversion and obligation to use a Spektrum Rx, the Servos (and gyros ?) that will not work at full speed/torque, and, more important, the motor that will under 1 cell be less efficient that a similar motor (with lower Kv of course) under 2 cells ?
In addition, under 2s, we can use some very light tail motors like this 1,4 grammes (the weight saved here pay by irself the extra weight of the 2 Lipos! ): http://www.wes-technik.de/English/Motors-Brushless.htm
And also use this type of Falcom Combo at 4,8 grammes for 2 servos + FM Rx. Again, the weight saving pays for the 2s battery.
But since most people go the 1 cell operation route, I must be wrong somewere ? What did I miss ? J
Thanks for your kindness
UPDATE: je viens d'apprendre de FALCOM que leur combo 4,8 gr fonctionne aussi sous 3 volts. Donc, c'est aussi une solution pour ceux qui veulenbt rester en 1 cell(a condition que les 2 servos digitaux inclus aient assez de peche sous 3,5 volts !) |
