I use it - on very small model -
the radio is setup to give flaperons -one switch
then flaps only in two positions - on another switch
This works extremely well for short landings /takeoffs
The model weighs 40 grams including battery
fully porportional with exponential and coupled controls as desired
Working with these new tiny setups are a boon for experimenting - cost is minimal and you actually see what can be done -
You can't beat experience
