Agreed - ail diff decreases yaw (which is caused by drag of the down going aileron. On slope soarers with no rudder, I start with 100 up / 50 down and tweak from there.

Thanks very much for the quick replies and info gentlemen. I’ve set the ESC at 7.5v which provides a nice balance between the lower and upper limit for the servos - all the best to you, Andy

Gents, my ESC is an AM116A…and has selectable BEC outputs of 5.8, 7.2 or 8.4v. My rx is a r3008sb and my servos are Theta 989. The Futaba rated and operating voltages ranges in the manual seem reversed. I’d assume the ‘operating voltage’ upper and lower limit would be within the ‘rated voltage’ limits. But Futaba have this the wrong way round! My question is can I select an 8.4v BEC output and NOT blow up my receiver? Thank You The reason I’d want to do this is to get fastest response from the Theta 989’s with them working at 8.4v as opposed to 5.8v

Aileron differential creates yaw, and rudder corrects yaw. In slope soarers with v-tail I.e. no rudder per se, aileron differential is very relevant. In almost all other cases, it will help a plane roll axially…but if you’re interested in aileron differential, chances are you use the rudder anyway rendering it little more than an interesting academic discussion bearing little relevance to most of us!

Thanks Adrian - good to know but my Tx is the T16SZ not the IZ. I have speech working for the timer (time remaining)… but I think speech is a more advanced function on your newer TX model.

Hi - I have a couple of models where I’m interested in installing the SBS-01C current sensor. It’s a pricey unit and as I’m not keen (at all) to glance at the display whilst flying to read current, voltage and battery capacity consumed, does anyone know if the speech warnings actually work on the T16Z for this telemetry sensor. And if they do, what do they actually vocalise… Many Thanks, Andy

Interesting, so can I ask how? The T6K has only one rotary dial, and I need a thumb on the ‘throttle’ and the other one on aileron/elevator…meaning I can use the slider at the same time to tweak the elevator trim whilst braking

Hi Simon - think about it for a second…the charger you’re referring to is a physical device with constraints on space within the housing, fan size and component temperature thresholds. Unless you use a dedicated discharger which will have heavy multiple heat sinks within its housing and a bigger, faster exhaust fan and different components, the charger will determine how quickly it can discharge a battery to a specific voltage. It’s really not suprising. If it allowed you to determine the discharge current, it would probably explode, go on fire or fail…probably all three simultaneously. It’s the same as a bass audio speaker - needs to move a big amount of air slowly, so requires a huge magnet often with heat sinks as opposed to a tweeter which moves a small amount of air quickly and using a small magnet.

Thanks so much guys for the input - I’m going to go with TFHSS for this one. I’ve been using a R3106GF in a 60” Edge and it’s been flawless, but want the benefit of diversity in this slightly bigger model. I’ll probably use a 430 Optiguard pack too as a main batt backup. Hey Mark, I’m doing some club instructing and the TX’s the club purchased are Spektrum…the menu structure is incredibly methodical and much as I love and use Futaba myself, the ‘Futabese’ manual and use case descriptions (especially for slope soaring) really do leave much to be desired in comparison 😁

No - the charger does not let you set the discharge rate as it has the responsibility (as it were) to dissipate the energy…not you. So by all means set the discharge rate to whatever you want but the charger will determine the rate used based on its construction, heat dissipation, heat sinks, cooling etc

You’re maybe overthinking it - the charger will almost always determine the discharge rate. When you think about it, where does the energy dissipate to??? - it’s certainly not a motor! If you want to discharge lipos quickly, you’d need a purpose made discharger

Interesting thread - I love my T6K but found it limiting when needing to adjust the amount of elevator deflection when engaging flaps (crow) for landing using the throttle stick. Presetting flap/elevator and testing in flight at altitude is great BUT if your presets are off the mark, you’ve got to land without brakes/crow, which can be messy as the T6K has no sliders to do this in real-time and you can’t use the vario as your left hand is managing rudder and your right hand managing ailerons. I got a T16SZ and the options available are easier to set up as there are many many more wing types and mixes available … and the sliders are pretty much essential imo

I know this may not help but I upgraded to a 16sz as the T6K whilst terrific for fixed wing, was limiting for slope soaring - specifically being able to trim elevator when crow for landing was assigned to throttle. The SZ has a slider so I can adjust elevator trim in flight rather than bringing in crow with a predetermined amount of elevator and hope it stays a tad nose down. It’s a great radio but the SZ is significantly better

Hi - Is there are requirement to use FASTTest in preference over S or TFHSS receivers in a 67” Extreme Flight model? Many Thanks Andy

If it’s an electric model, the first step is to change THR to Motor. If you don’t, and it’s an electric model, you’ll ‘test’ the switch when the throttle stick is at around. 15% (almost no one tests throttle cut running the motor or engine at 100%) and it cuts the motor (seemingly all as expected) BUT if you do it again and this time the stick is at around 30%+, toggling the switch WILL NOT stop the motor! This is downright dangerous so changing THR to Motor is an important first step, Some dude called Chip Hyde did a video on this and even he messed up how electric set up should be done as it relates to safety.
