" Does a Rabe Rudder reduce line tension? "
Yes & No .
Was getting hysterical with this bloke , last saturday ,as the RUDDER is Not Connected .
EXPLAINED IT , as , Mr Rabe put it . In a P-51 , with 1650 Cu. In. or Horsepower or suchlike . When it traslates from tailwheel to level , or V.c.V. ,
He Found ( and one or two other people ) that it skived off into the sceneary ,UNLESS you kicked Rudder In , at the Transition !
THIS is where his ' P ' effect - one prop blade near vertical - the other at double pitch - ( shall we say ) has things askew .
2/.
If theres MUSH ( Vertical yaw ) you get 'P' effect in manouvres .
3/. GYRO . try ' sopwith Camel; '
https://vintageaviationecho.com/sopwith-camel/This is why LIGHT propellors are GOOD , not to say there arnt other reasons . And Nobody uses a Rotary engine for Control Line aerobatics .
4/. It Should get the LINE TENSION - EVEN .
The Ten Ton STREGA withoout the Rudder Connected , Yanked your arm in the top of the insides in Sq 8's , and floated across the tops of outsides . More or Less .
Connecting the Rudder got the Tension pretty much even . In the wind its arm stretching , but 70 or 80 ounces does that . But still as a scriber is excellent .
IF it has enough power .
RIGHT ,
So Mr Mustang swings on rotation . Kick the rudder and she dont .
this might be regarded as YAW .
So our widdle wudder stops the wobble , yaw - dutch roll , weave , wobble, pitching, and bobble . We Hope
PARTICULARLY on something like the Sea fury etc , with Thrust line , side are , wing Center , and most other things OFFSET , as compared to the renowned ' in Line ' efforts .
SO ,
Like a TRIUMPH or NORTON ,
At The Limit , would drift , a jap. job would flex wobble weave & bite unfortunate inept opperators .
A thouroughly offset contraption like above , may benifit enourmously , stopping it going free flight at the top of the hourglass & into the clover ,
If your HAMMERING IT , ' Hitting ' the Corner . The plane set up so you can ' HIT ' Full controll without it stalling or other misbehaviors .
YOUR AVERAGE , not so scale device might not benifit to such a degree . But , As a Windy Bloke says " Over 12 inch of propellor ' its a neccesity . tickly weighty ones .
As they Swing the nose ,
ALL the rotateing weighty stuff , prop, spinner , prop driver , crankshaft , is IT . Wich is WHY Triumphs with CENTRAL FLYWHEELS outmanouvre inline displaced flywheel / counterweight jap fours ! .
WHEN the plane falls in a hole in the air , and throttles up , as its getting blown to eterity & back *, The amplitude of the forces can vary significatly . In MULTIPLES even . as in 2, 3, 4 times the load .
* ( with an ' N' . )
This is when you have to hang on , dig in , and dont falter . Helps if the aeroplane does too . The rudder can help there , proportionately .
Havnt used em a lot at all , but the one i did followed the straight , 1/8 T.E. out , 3/8 t.E. out - up level, down , set up . Fine Tuning - Wots That .
Throw it in the ballpark'n live'n'lean . So you dont back into a hole .
