WelshZeCorgi Posted August 11, 2016 Share Posted August 11, 2016 I can snap roll the FW-190 and P-51, but can't seem to do it in the BF-109 because of the leading slats? Is there a special way to snap roll the BF-109 or is it just not possible? Link to comment Share on other sites More sharing options...
LURKINGBADGER Posted August 12, 2016 Share Posted August 12, 2016 Yes i tried it to, to me it looks/feels like the ruder does not have the authority to do that, i notice it when i do landings with crosswinds with the 109 compared against the 51d.

SlipBall Posted August 12, 2016 Share Posted August 12, 2016 I have been saying for a long time now that the rudder lacks authority both on the ground and in the air...I have shown this visual evidence before, just look at that turn prior to touch down, and the pilots use of the rudder both on the ground and up in the air.

Ala13_ManOWar Posted August 13, 2016 Share Posted August 13, 2016 Last time I checked snap rolls were performed by a quick stick flick leading into a sudden stall, only marginally aid by rudder. You sure you are looking for it correctly? S! "I went into the British Army believing that if you want peace you must prepare for war.

Shahdoh Posted August 13, 2016 Share Posted August 13, 2016 A snap roll is achieved by stalling out 1 wing before the other. At no time are ailerons utilized in a proper snap roll. At an appropriate speed for the a/c, pull back on the stick, then input rudder into the desired direction of the roll. The induced yaw will have the advancing wing generating significantly more lift and the other wing will stall out. The miss match in lift will roll the a/c around, no ailerons required. To stop the snap roll, neutralize the pull and a bit of opposite rudder initially. The trick is in the timing to stop the a/c at the desired attitude. Here, Kirby Chambliss describes the manuever, a bit over dramatic IMHO, but the results are the same. http://www.popularmechanics.com/adventure/sports/a6585/how-to-snap-roll-a-stunt-plane/ Link to comment Share on other sites More sharing options...
RedShoes Posted August 13, 2016 Share Posted August 13, 2016 You do not snap roll a Bf-109, the Bf-109 takes you out for a snap roll when she so decides.

At no time are ailerons utilized in a proper snap roll.Did I say it is a roll flick? ;-) Anyway, opposite roll while stepping rudder and holding stick back helps the snap roll. But yes, no need for it. S! "I went into the British Army believing that if you want peace you must prepare for war.

Farlander Posted August 15, 2016 Share Posted August 15, 2016 (edited) A snap roll is achieved by stalling out 1 wing before the other. At no time are ailerons utilized in a proper snap roll. http://www.popularmechanics.com/adventure/sports/a6585/how-to-snap-roll-a-stunt-plane/ It would be highly dependant on type of aircraft i would guess. All books i've looked at for description of aerobatic manouvers for gliding suggest use of aileron when doing a snap-roll. like this To anyone who doesn't get why you would roll opposite to the way you want to snap, here is why If you roll away from the flick, the aileron goes down on the side it will flick making the AoA on that wing greater, and create more drag(Fig D). Neutral means same AoAand drag on both wings, and if you would roll into the direction you want to snap you would be giving the wing a lesser AoA, thus also less drag(Fig B) (Extreme edits: Snap rolls are not done exactly like this for all airplanes. It is very aircraft dependant as to what control inputs you need to make. You just want the plane to rotate fast, stall out (autorotation, really). How you get it doesn't matter that much, it's the result of it that matters.) Edited August 16, 2016 by Farlander Link to comment Share on other sites More sharing options...
WelshZeCorgi Posted August 26, 2016 Author Share Posted August 26, 2016 Still can't do it, tried both suggestions but the slats on the stalling wing keep deploying and catching the stalling wing before a full snap roll is accomplished. Can anyone post a video of a successful snap roll in the Bf-109 in DCS? There are none on Google. Link to comment Share on other sites More sharing options...

Stuge Posted August 26, 2016 Share Posted August 26, 2016 If I remember correctly the manual does not recommend performing snap rolls because they cannot be performed reliably. http://www.104thphoenix.com Link to comment Share on other sites More sharing options...

ED Team NineLine Posted September 13, 2016 ED Team Share Posted September 13, 2016 Sorry I hadnt got back to you sooner, I did one the other day, I was in our internal testing version so not sure I can share the vid, so I will have to redo in another version. It was a pretty lazy snap roll, but then I wasnt expecting a acrobatic plane looking one either... It is tough, it wants to stay on its side if you try and back off too soon. But it does seem possible. Forum Rules • My YouTube • My Discord - NineLine#0440• **How to Report a Bug** Link to comment Share on other sites More sharing options...
