Allright, i have a rex 450s. I can get the machine setup for upright and inverted on the pitch curves pretty easly but, have a few questions.
1) After i got the pitch curves set up, i put the gauge on to see where i was at soo i could duplicate it later. It came out to somthing like: +10,+5,0,-3,-6. Has anybody else noticed this or am i really messed up ??
2) Where do you trim your machine? Is it trimmed for upright hover? Maybe trimed for piros? I can think of a few ways to do it and was just wondering what the mass consensis (sp?) is. Does anybody us a mix to help with trim in upright/inverted hover?
3) Does your machine stop in rolls ? I know i have to pull a little on the stick but, i also have to hold back stick when in an inverted hover and think that is why i asked question #2.
4) Will carbon tail blades help speed up the piro rate?
1. first off make sure all the levers in the head and blade grips are level. adjust the links in the head to acheive this. once you do the un plug the motor and move the stick to mid stick and switch into idel up. now with mid stick and in idel up, you should have zero deg pitch on the blades. now when you move the stick full up and full down you should have the same deg of motion in either way.
2. If your heli is set up properly, you should only have to trim it while upright. im pretty sure the "S" has the same battery mount as the SE. so mount the battery onto the small little CF battery mount not underneath it where it is level. this gets the CG closer to center which will help it roll and loop more smoothly. once its trimmed for upright hovering then when inverted it should react just the same way.
3. my rolls are smooth and dont stop. but what i think you mean by stop is hesitate, probably as the heli reaches inverted. well moving the battery to where i said in Q2 should help eliminate this. also collective management will help the heli roll and loop more smoothly.
4. carbon blades wont help speed up anything. they will help the tail be more solid in flight, i assume your using the 401. it would help to know what radio your using too. as for speeding up, just adjust the rudder travel to a higher percent. if its at 100% go to 110% and see how you like it then just adjust from there.
