It seems that most need to use the furthest position on the control horns to get MAX throws....
Same on their entire .50 size glow planes...

Exp. The Reactor .46.
I have the model but you cannot get max throw with the bevel they have on this model.
I had to cut wood to get the correct bevel to allow enough through (50 deg) to do 3d properly...
My point is, most people that have the Reactor do not get the necessary throw for 3d, and there for do not use the Lowest Control horn position
Because they do not need too
If the bevels were cut greater, then most would HAVE to use the lower position with the stock FUtaba servo horns (ridiculously short they need to update those things)
We would then see many issues with flutter....

2- things need to happen..
GP needs to supply dif. rods with there kits and or specify the use of longer servo horns (1inch or more)
Futaba needs to get with the times and have realistic servo horn lengths..
300oz servo with a 3/4inch servo horn??/ alrighty then....!
