After 32 pages of thread in one forum, and 15 in another... I pretty much determined that the hoverfoam is doable..although extremely difficult to actually fly. This is due in part to a lot of balance and coupling problems causing shortfalls that have to be mentally overcome to fly it.

I mentioned that we should carry on the thread thinking "hoverfoam" and how to better it.... well , that is not going to work as 32 pages later , they still haven't come close.

Some of them , I believe started of in the right direction ...but never continued by suggesting a)a duct tube and smaller control surfaces...and b) a counter -rotating prop at the top to kill torque. This adds weight and only adds a marginal lift factor. There is another project called the Levjet that looked to be sorta viable(more closer cousin to what I am doing) but I have not seen any discussions about the mix for that bird.

In the hoverfoam thread, there was some clues as to what might actually work.

Here's my take

Ok.. lets use a servo per fin.

Horizontal goes to elevator stick
Vertical goes to aileron stick
all surfaces work as a whole...elev operates both horizontal surfaces...aileron operates both vertical surfaces..

now lets use 4 stand alone outboard mixers...

we plug each servo into a mixer...and the original input to the mixer.

now we take the rudder output (what I want to use to create twist) and split it 4 ways and plug to second channel of each mixer.

everything should work correct...and when the rudder is used, they should twist .This may have to be modified to make sure the twist is in same direction . I suspect one fin axis may have to be reversed...but it has to be reversed at the mixer...not at the rudder/reciever....or transmitter..



RCmaniac,

Whatever that thingie is in the pic seem to be doing just that....but I can't tell what it is as the pic is too small.

Maybe this will get the thread "on track"

If there is a mix that can be achieved in say a Futaba 6 AX transmitter, then that is the mix I need...or maybe someone has modded the mixes to get to that end.
