Piper Cub Posted July 19, 2011 Share Posted July 19, 2011 Not sure where to put this as it could probably go in a number of different places. I've always loved glider especially scale but the big problem was getting them into the air from a flat field. Brushless and leccie have certainly helped in that respect. So, lots of gliders on the market now come with folding props (OK, I know they're not new) so when you cut the power the prop folds back to reduce air resistance. But, stopped throttle is normally bottom stick and throttle stick (mode 2) also has rudder. Now at bottom throttle stick there's not a lot of waggle room for rudder movement. The obvious position for stopped motor and folded prop is middle stick, this gives plenty of movement for rudder without banging against the stops compared to bottom stick. However how many people fly like this (stopped motor at middle stick, throttle operating above this point)? Is it common to always set throttle off at bottom stick on a powered glider? For leccie, is it easy to set the motor to only start above half stick? Quote Link to comment Share on other sites More sharing options...
PatMc Posted July 19, 2011 Share Posted July 19, 2011 The side movement of the stick is the same top, middle or bottom on every Tx I've come across.I fly mode 2 with several motor gliders without any problem. Quote Link to comment Share on other sites More sharing options...
Olly Giles Posted July 19, 2011 Share Posted July 19, 2011 pat is right there is no difference in the ammount of movement from the middle to the bottom of the movement. If its more comfortable to have the stick in the centre you could experiment with different throttle curves or the End point adjustment.

PatMc Posted July 19, 2011 Share Posted July 19, 2011 Some folks use either a switch or slider on the Tx for throttle control on motor gliders. This means it's either on/off throttle or proportional but coarse throttle control. They then use the throttle stick for full proportional control of spoilers or flaps.

My transmitter allows me to set a "centre beep" which warns my when I move the stick up to the middle, before power comes on. Quote Link to comment Share on other sites More sharing options...
Alan Williams Posted July 20, 2011 Share Posted July 20, 2011 You havent said wherther the glider is rudder elevator or has ailerons.If RE just put rudder on ch.1.I fly my re gliders that way.Alan Williams Quote Link to comment Share on other sites More sharing options...

Martin Harris - Moderator Posted July 20, 2011 Share Posted July 20, 2011 Got me wondering if it could be done with some mixes utilising a 5 point curve and some spare channels - I might have a play tonight! Quote Link to comment Share on other sites More sharing options...

Lee Smalley Posted July 20, 2011 Share Posted July 20, 2011 i use a flight mode switch only in launch flight mode is the throttle active after that it does nothing unless in land mode where it controls the crow braking Quote Link to comment Share on other sites More sharing options...

Edited By Tom Satinet on 20/07/2011 10:53:27 Turnigy 9X, using er9x firmware So your saying the movement of the stick (left to right) is restricted when the throttle is "down"?

Frank Skilbeck Posted July 20, 2011 Share Posted July 20, 2011 I've not seen rudder movement restricted when throttle is either full open or shut, would make doing stall turns a bit difficult if it was restricted. Quote Link to comment Share on other sites More sharing options...

Bob Moore Posted July 20, 2011 Share Posted July 20, 2011 I can appreciate what you mean about using the left stick when it's in a bottom of the range position. I set up my Westwings Orion leccy glider so that the right stick (as in ailerons left right) controls the rudder. I just plugged the rudder servo into rx channel 1? It feels very natural as it's the stick I move to turn left right? Just to clarify, that's throttle left, elevator and rudder right.

Similarly in mode 1 rudder would be on the left stick for a model without ailerons. Quote Link to comment Share on other sites More sharing options...

Pat, I thought mode 1 only swapped ele and throttle, so primary turn would still be on the right, ie rudder for RET, aileron for full-house?Edited By Bob Cotsford on 20/07/2011 14:08:58 Quote Link to comment Share on other sites More sharing options...
andy watson Posted July 20, 2011 Share Posted July 20, 2011 I might be wrong here, but isn't it the case that these models have throttle pretty much on or off? In which case you could assign the throttle channel to a switch. If you need a mid range then a 3 position switch could be used. Alternatively is there scope for a load of expo on the throttle channel so slight upwards movements of the stick don't fire the engine?

Lee Smalley Posted July 20, 2011 Share Posted July 20, 2011 andy no if you want to just cruise over to a thermal that you can see why would you want full power!! on my glider full power sends it like a rocket skywards if i just need to climb a tad then i dont want to flick a switch and get a kick up the backside, also on launch i dont want full power as it comes out of my hand i want half get the wings and surfaces working then hit the power, its much smoother than BANG!!!!

PatMc Posted July 20, 2011 Share Posted July 20, 2011 Beereycalfs, I use the throttle stick for motor gliders but I nearly always just bang full power & climb upwind at a steep angle for 15 - 30 secs then glide. It's a near simulation of the launch pattern of a glider from a hand or power winch or from a bungee. TBH a switch would be just as useful for me so long as I could operate it with my left hand.

Gaz Elliott Posted July 20, 2011 Share Posted July 20, 2011 why not set the throttle to one of the switches eg channel 5 or 6 switch for gear/flaps. If you have flaps these can then be programmed to use the throttle stick to give a varied amount of flap. I have not done this my self but have read about it some where. It certainly would resolve your dilema I think Quote Link to comment Share on other sites More sharing options...
John Privett Posted July 20, 2011 Share Posted July 20, 2011 One of our club members flies some high-powered F5B-type leccy gliders. On those the "throttle" is on a switch - but mainly because the current taken by the motor is rather more than the ESC is rated at. As long as the ESC is either "off" or "on" it's OK, but at a part throttle setting it would let the magic smoke out in under a second - or so he tells us! Hence the switch - either full on or full off, so no chance of fumbling the throttle stick and leaving it on part throttle... Quote Link to comment Share on other sites More sharing options...
