I liked the extreme manuverability of my CAPs... but the landings....
I played around with no horizontal at all... broke 3 props trying to take off, gave up on that.. reinstalled the horizontal at the bottom of the fuselage.. receiver battery failed in flight!
The Byron CAP flew like a CAP... great in the air. Knife edge close to the ground and mooning the coffee club in the pits was not a good idea!

Incredible design- but much maligned by some .
I always get a kick out of the " importance of the horizontal stab placement " proponents..
the downwash/ hogwash arguments
that one and the "spiraling slipstream".
better than Alice in Wonderland.
The setup for each design is simply different
strange, ain't it!

Of course. Removing the stabilizer moves the neutral point forward

Having no horizontal and the prop a goodly distance above the wheels is more of an influence, with nothing to hold the tail down at very low speeds with the propellor slipstream.
Howsomever, these planes made the transition to tailless nicely...
The profile Somethin' Extra had those large elevons, the Krafty 25 had the nosewheel.

Those pesky short airplanes
Fun to play with but not very forgiving at slow speeds
To me, aircrafts are all about lever arms and short levers tend to make short work of things ---

I still have the taillless Fazer in that photo. It's been covered and ready to have the equipment and motor installed.... since 2002!
.
All that's needed to make a tailless is cut the tail off, move the c.g. to 12-15%, reflex the ailerons which have become elevons.. go fly. For a while.

My flying wing experiences started loooooooooooooong ago with a control line O&H 23 powered delta like thing
The recent bout was with small electric stuf flying disc and other stuff.
The extremely broad speed envelope is interesting .
The new AS3X stabilized flight rx by Spektrum should proove to be an advantage for a really fast wing setup.. We havebeen flying these on "tricky" small fast models - makes em as docile as a bunny rabbit.

49.....FORTY NINE>>>>>> geez.. years ago I was flying AMA pylon with Cox Olympic .15s delta wings. I found out then I was not suited for high speed flight... spent more time analyzing why the plane was doing whatever instead of flying it. As well as wondering which point was the front. Amazing how much territory the parts can be found in after impact...
Slopers turned out to be a better venue for my peculiar flying skills with odd shaped airplanes... and the hike to the bottom of the hill and back up is good for the body..

I tired of racing - mostly spooked by the new racers who overcooked em on turns - and would crash too close for comfort.

Pattern & IMAC, much safer -

hey guys,I am new here and i had just tested my R.C plane a day ago.As soon as i tried to take off my plane flipped to the left on the ground and i destroyed my wing and the rudder as it snapped.The plane would not take off but would simply flip and roll.I was flying into the wind but i suspect my firewall was tilted.Is this the reason?Or is it because i may have had a larger polyhyderal on one side?The plane was a ft old speedster and i am very eager to improve myself ad get it in the air.I am a begginner and i know my question may sound dumb but please try help.Thanks guys.

I have re-posted your question here https://www.rcgroups.com/forums/show....php?t=2704184

in this forum https://www.rcgroups.com/beginner-tr...ft-electric-8/

check there for a series of Q/A to help determine what happened and why and how to fix and avoid that in the future

It appears that it will use skin sensors to change and adapt the flight control surfaces to fly the airplane.
Sounds a bit like how a bird flys, you know, the one that poops on your car.
For miltary purposes, that sounds OK.
I doubt you will see it on a commercial jetliner for awhile.
Don't want to wipe out 500 people if the computers decide to go offline because a bit of ice in an air data port....

The full sized one will definitely have some means to sense any sideslip and compensate it before it becomes too great for the drag rudders to handle. I imagine that it might also have some form of emergency drag chute, but on a fighter plane if all control systems fail the last resort is always the ejector seat. Replicating this in a model is probably feasible, but not trivial. Maybe using two pressure sensors on static ports on the fuselage sides and comparing their values?
