I have just ordered my first plane which will have retracts (no Idea how its taken me so long!)

It is a seagull super tucano (90 size) which i´ll be fitting with a DLE 20...

In this plane (4.7kg flying weight according to the manual). Just ONE retract servo is used.. which is installed in the fuselage and every day you fly, as you mount the wings on the wing tubes you also have to install the wings undercarriage´s pushrods into a clevis inside the fuselage!

I can just see that being a headache and needing adjusting every time...

SO.. I just happen to have from a previous order I screwed up some mini retract servos I could very easily hide in the wing... BUT

If the manual looks for 1x 12kg servo for all 3 wheels..... Would I be ok with 3x 3.4kg servos? (roughly close to 4x3=12)??????

In short: is 3.4kg/48oz-in enough torque for one retract on a 90 size model?
