Good afternoon all, i need help selecting a servo that has adequate torque and speed for my model, i have an alfa models micro p-51 mustang, the instructions recommend 3 gram servos but unlike other alfa models does not give the minimum torque requirements (does say not to use linear servos) i would like to use the lightest servos as possible, below i have put all the info i have on the control surfaces, auw of airframe etc and the servo i would like to use and also a youtube link to a video of the model, if someone can help me out with what i need, i would be very grateful

Wingspan: 460mm/18.11in. Wing area: 3.7dm2/ Weight: 65 grams/2.3oz. Motor: 7gram 2000kv brushless outrunner. Elevator: 165mm/6 1/2" width, 2mm thick at leading edge, 14 area, 6mm deflection up and down, pushrod controlled. Ailerons: 90mm/ 3 1/2" width each, 3.5mm thick at leading edge, total area 23.4, 6mm deflection, both ailerons controlled by single servo via two pushrods.

Here is the servo i was thinking of using; Tactic TSX1.9 coreless Weight: 1.9g Torque: @4.8v Speed: 0.04sec/60 degrees @ 4.8v

Here is the youtube link for flying characteristics and general speed envelope:

Can anyone tell me what type this plug is called? It's for my jr x2720 and want to make some charging leads for my tx batteries, the closest plug I can find is a jst-ph but probably won't fit, when I search on Google it's just called a jr plug, not very helpfully. Pictures to follow. Any help would be great.

Does anyone know of why my frsky 2.4ghz 4 channel receiver will work with everyone of my planes except my skyeasy glider which I just get a beeping sound from the motor? The green light comes on the receiver so it's binded to the tx, bit confusing lol

Hi everyone, im hoping some one can recommend a good 4 and 6 channel 35mhz synthesized receiver or other receivers that will work with my JR x2720 transmitter, i have micro planes and small foamies so im looking for a light weight receiver thats lighter than the JR receivers but more reliable than corona ones, i have bought 4 corona receivers and 2 didnt work and the other 2 didnt work very well. Hope some one can point me in the right direction. Any help would be appreciated.
