Spin is full stall then rudder in the direction you want to spin. You can add aileron the same direction to tighten up the spin or opposite aileron to flatten in out but ailerons aren’t really necessary for spins. Spins in the above video are done with aileron and rudder the same direction. Snap roll is just an abrupt horizontal spin and you do rudder and aileron the same direction for positive (pull) snaps in the video. But with negative snaps in the video you do opposite rudder and aileron so curious as why? A spin/snap is a spin/snap so why the difference if it’s a push instead of a pull entry?
@Hugocraft, You are correct in your statement that aileron is not needed in a spin. This being said, our models spin much better with the use of ailerons. This is especially true in an IMAC spin. It presents much better and is much more predictable/controllable. Additionally, aileron is not used in snaps in a full scale plane but again, we need aileron to perform snaps with our models due to low wing loading, Reynolds numbers, etc. On the comment about a snap being a spin/snap being a spin/snap, this is incorrect. If you are spinning from inverted you would need opposite rudder to aileron to get the same results as same direction movements in a positive spin. The reason for this is because the yaw axis is reversed when inverted but the roll axis remains the same. If you were to fly same direction controls in a negative snap you would end up with a cross controlled snap that will look more like a horizontal knife edge spin than a snap roll. Thank you for your feedback. We hope this helps. Keep the questions coming.
@@FlightReviewz After reading your comment I had to use a stick plane and think about which way the rudder and aileron would be deflected to get the same motion with positive snap versus negative snap. You are right, Example of positive snap to the left would be left aileron and left rudder then negative starting from inverted would be left aileron again but right rudder to rotate to the left. Fun to re-think about it. Left aileron rolls left/counter clockwise and right aileron rolls clock wise no matter if you are upright or inverted. But left rudder while upright is a yaw to the left but when inverted left rudder would cause the plane to yaw right when viewed from the ground.
Good morning from Spain, I have been following your channel for some time, both construction techniques and flight techniques. One of the parts that I follow since I belong to IMAC Spain is that of the IMAC tables or sequences and after the stoppage due to the pandemic it would not be too much if you had time and could make a video of the Sportman 2022. Thanks in advance and greetings.
Greetings, Juan Carlos!! We will do our best to get out and record the 2022 sequences as soon as we can. Jason has a broken ankle currently and it is making it hard but we will do our best.
Can you break down the stick inputs for the outside, 4 point roll. As I watch you fly it, I don't see the rudder inputs I try to make to make to keep the radius so curios what you are thinking and doing as you execute it.
Okay, so that one is going to change based on what model you are flying and also how much airspeed you are carrying. In the video I actually give a little bit off "opposite/down" rudder on both of the knife edge points to keep the radius of the loop consistent. If you slow down too much at the top you will not have to do this as the plane will "fall off" and tend to point toward the ground quicker. I find it easiest to carry at least half throttle through the 4 points. When I do this I just have to find the best rudder inputs to keep the radius the same. With a little practice it is very easy to create a repeatable process to get a nice, round loop with a centered four point at the top. Hope this helps. If you think it would be helpful we could possibly do a video focusing on this type of maneuver.
FlightReviewz I do. For me how to do the inputs in a way that minimizes down grades is what I’m keen on learning from others more so than what the maneuver looks like flown though that’s certainly not to be taken to mean these overall videos aren’t extremely helpful. But once you know the sequence flow, I would like to see follow up video where some of the higher K value maneuvers are broken down and shown how to fly them well and how to adjust them for high wind days. By the way, one of my IMAC planes is the same AJ Lazer you are using. Also, just for a datapoint, it would be interesting to me to see your throttle curve in that Lazer and to know how many rpm on the ground you are turning at mid stick position along with your prop size. A ballpark way to know how much relative to me ‘speed’ you are flying with at mid stick position. Thanks!
Hello my name is daniel for SA, i do like your kind of style the way you fly, I watch most of your videos but I'm flying for more than 7 years and think of leveling up my skills, i don't really know where to begin and if I'm doing some maneuvers right...need guidance where to start and how to upper my skill.
Hello Daniel. Thank you for your kind words. "Leveling Up" your flying can be tough. Are there IMAC competitions in your area? I have found that flying with a "purpose" (practicing a specific set of maneuvers) really helps me improve. If you cannot get involved in IMAC locally I would recommend working on things one at a time and then connecting them down the road. Also, if there are any specific things you would like us to make a video one, please do not hesitate to ask. We will do out best to accommodate.
@@FlightReviewz I do want to upgrade my skill to be become more comfortable doing certain maneuvers...I do want to fly IMAC basic in 2023..I'm not sure if my plane is setup right for the purpose of IMAC..would like to know about the CG for an IMAC plane where it's to be before I add mixing. I do fly the model on factory settings so my expo is at 50% to 70% is it a problem or do i have to bring it to 20%..I just need guides to show me in the right direction where i must look for or what must i bring down or what must i set. thank you for your reply
@@djslabbert2488 CG is a tough thing to specify. It varies greatly from plane to plane, and from pilot to pilot. The most important thing is making sure your plane tracks well. I use the least amount of expo as possible to help keep things smooth. Too much expo will cause the airplane to jump when you get to a certain point. Just my .02 I would download the Basic sequence, learn it, and go to a contest. You will meet plenty of helpful people that will be more than happy to get you pointed in the right direction.
I will check to see if you have videos similar to M. Fargo about 3D etc maneuvers... but you explain at least this type of video,very well almost spoon fed.
Thank you. We are planning to do more 3D how to videos once we get the EF Yak up and flying. We also have a new 120cc 3D plane to build so that will help motivate us there as well.
Really good IMAC video:)
Thank you very much @MaxMorgan!!

@@FlightReviewz thanks for everything ... and that Jason recovered as soon as possible and the ankle is perfect.
Love how it fly's...
A great bird for sure, Jose!

We aren't exactly sure what you mean by, "outside, 4 point roll." Are you referring to the 4-point roll at the top of the loop in maneuver 3?
FlightReviewz yep
