    Love your videos! I purchased my Bison XT in March of 2023. Thank God Motion RC fixed it so that the tires came preassembled and gluing no longer required! As for the tire air adjustment and wing tip scrapes, I learned the hard way..... Less air is way better, she handles like you said as an extension of the shocks.

    I always have to start with nice flying because that is just a fact. I think it would be helpful for those pilots that are average to consider continuing to fly with the slats to improve their skills. You have demonstrated that the plane can be flown well even with the slats. If you always fly in your comfort zone your skills will either not improve at all or improve very slowly. Just one man's humble opinion.

People are different and can look at it any way they want I guess, but I can't imagine ever not wanting to learn more and get better. My journey in model aviation has been very consistent and predictable. As my modeling, set up, and flying skills increased...the fun and confidence I had did as well, and my frustration decreased. Win win. Happy flying!

    If you haven't tried an Avios Grand Tundra, you owe it to yourself to try one. It flies on 4, 5 or 6s and is a real STOL hotrod on 6s. 67" of very well designed, tough as nails bush plane that I use in weather when you just wouldn't try anything else. Comes with switchable landing lights, off, on , or flashing and all nav lights. Robarts style gear, Horner tips and huge soft tires as well.

    Good Job On the vid and an option when having a problem. I am looking to use the slats, but snow and wind, here in Montana have postponed that. Reading and watching things on Bison caused me to use a conservative approach to the slats. The first thing I noticed, the slats would not close completely. The second at full extend slats were too far up. Any gap at the rear of the slats means slats are still working and raised more than the curve of the wing causes downforce. My remedy was removing the linkage covers and ending by cutting off four or five threads from the hook that extends the slat. After a closer adjustment of slats, I ended up with a tight seal at closed and a parallel curve when fully deployed. Can hardly wait to fly. Recommend having the slats positioned properly and practice sometimes. Pilots may realize how much fun stol can be instead of neutering the Bison to a regular wing.

    • @sanexup1038
      @sanexup1038 2 роки тому

      I'm just curious because I haven't seen the mechanics of the slats, but do you think it would be possible to install separate lightweight servos to work the slats? I know some foam modifications would have to be made but does it seem feasible or a waste of time?

    • @ModelAV8RChannel
      @ModelAV8RChannel  2 роки тому

      Thanks for watching and the comment Stephen! Believe me...I have explained how slats work, and how to properly fly with them in detail on the Hobby Squawk forum for this thing. (If you'd like to read it my name there is "Starck Mad" after a P-51 I used to fly) Some blame the plane, some admit they just don't want to learn how to use rudder and throttle well. I love it with slats...our first two videos of the Bison are with them. We just wanted to give our take on what some are doing with it. Different strokes for different folks I guess...not everybody wants to learn new skills.
      That is a creative mod, but you may not want to close them all the way. They are not aerodynamic slats (slats that go fully flush with the leading edge from front to back), they are fixed articulating slats...which means the leading edge of the slats (where they pivot from) are always separated from the leading edge of the wing. If you close the trailing edge airflow will still enter at the front of the slat, but have no where to go...so it will roll back out and disrupt airflow over the leading edge. Not sure how adverse the affect will be, but it will be an adverse affect.
      What full scale STOL pilots with fixed articulating slats do to render them ineffective (and bear in mind they have independent control of the slats and flaps) is they rotate the trailing edge of the slat up slightly...not enough to become a spoiler and kill airflow, but just enough so the air flows between the wing and slat normally instead of hitting the bottom of the slat immediately and accelerating through the narrow gap over the wing the way it does when the slat is in the proper position to work as a slat. Also bear in mind this is all done slow, upon landing when the pilot doesn't want the angle of attack to increase too much...as in when they are going in to a back country place they've never been and they want to see whats ahead of them over the nose. Riding the slats with them in the proper position and flaps down with the angle of attack high would be what they chose landing in a controlled environment...like at a STOL contest when they absolutely want to get as slow as possible and only need to see a landing line out the side window.
      Fixed and fixed articulating slats will cause some drag no matter the position. Even in the proper (working slats) position when you're flying straight and level at speed they are ineffective anyway. They don't start working until the angle of attack increases when you get slow...that is when the most of the airflow starts to go between the wing leading edge and the slat and that is when the magic happens. At speed (level, low angle of attack) most of the air flows over the slat anyway. In our first two videos on the Bison everything you see...fast flying, aerobatics, slow flight, etc. is with the slats in the working slat position...open following the same contour of the wing.
      Sorry for the long response, but I wanted you to know the "why" of what I'm saying instead of just saying "do this". In a nut shell...there is no need to close the trailing edge of the slats...you are not improving aerodynamics by doing that. If you could close both ends and get the whole slat flush with the leading edge of the wing that would decrease drag and improve aerodynamics...that would also then be an aerodynamic slat. With only the trailing edge of the slat closed...at speed it will just be more drag (as some air will still get in the gap with no where to go), but once you get slow or change the angle of attack much in a sudden maneuver...it will be a bigger issue when most of the air has no where to go. I would just forgo the cool moving part, lock the slats in the proper position, and fly it. That's what we did...been working so far. I hope this helps my friend!

    Very interesting video Adam, I refrained from fitting the slats on my Timber as I just didn't fancy using them!! But its surprising seeing how much more they can reduce the speed of a plane!! Although the Bison seemed to be flying quite slow without them, very interesting to see how the choice of wheels can also affect the STOL characteristics of a plane too!! Very enjoyable and informative video, and some great filming from Heidi 😄👍

      I dunno Al. I enjoyed the Bison, that said...this plane was episode 1, our very first review, and the plane we kicked the channel off with. The timing was good as it was brand new, and we were the first video other than MRC out there. That episode taught me a lot about doing reviews. I liked it, liked flying it, and flew it well. What I didn't consider was how much rudder it required to fly well. Coordinated turns are a must. Also when I flew it slow, and really got the nose up...I was using 3D pilot harrier skill to do it. That stuff is second nature to me, but when other folks started getting them...most had problems flying them well. It taught me to think about other pilots and what skill is required to fly a specific plane. This one is one of the hardest foam bush planes out there to fly well. I enjoy that kind of challenge...most others did not. There are a lot of bush planes I'd suggest you put on your list, but this one would be at the bottom of that list honestly. For a bit more than this, the Carbon Z Cub or 150 are the best ones out there in my opinion (CZ Cub is my personal fav foam bush plane) and are bigger. The Arrows Husky is fantastic as well, and its almost as big as the Bison, and cheaper...and a way better plane.

      Hey Jesse, thanks very much! Glad you are enjoying the channel. To be honest I don't know what the thread size is, but couldn't you use the nut that comes with it? Most aftermarket spinners will have a back plate, and the spinner part will bolt on to that. If not, another option is to take the prop adapter off and take it to a hardware store, then you can find a matching nut. You also may be able to use a Dremel to open the holes in the stock spinner big enough for the 17x10.

      To be honest I didn't even know they had a V2 until I read your comment. Looking at what they have done the FPV guys will be a little bit happier. The gear will be more sturdy, and the tires easier to assemble. That said it sounds like they've added weight which this plane didn't need. It's already heavy for what it is. They still have that goofy flap to slats set up where when you put the flaps down the slats rotate into spoilers which is counter intuitive and makes the plane fly like crap. That's why we originally disconnected that system and just used the slats as fixed slats permanently. It's still a fun airplane but it definitely requires a high level of rudder skill.

    • @ModelAV8RChannel
      @ModelAV8RChannel  2 роки тому +1

      Hey Tim thanks for watching. A few things - we have our CG rear of what is recommended, and we have 50mm of up elevator throw...so we don't require much up trim...some but no where near maxed out. With the slats you have to use power as well as elevator to flare and get the nose up. A typical power off landing is not really possible. With the slats off power off landings are possible, but you will need to have the CG and throw settings where we do. Our full set up is posted on our first Bison review video. (episode 1 on our channel). For this "no slats" episode we did not change anything in the set up other than removing the slats. Hope this helps !

    • @ModelAV8RChannel
      @ModelAV8RChannel  2 роки тому

      Hey Tim, with our 3700's I'm able to slide the back of the battery under the tray about an inch or so before we strap it down. They are a good bit lighter than the 5000's most people use, and a 5000 is to big to slide under the tray any. If you are using the bigger battery you may have to put some ballast back on the tail to get our CG. Shouldn't take much if you put it that far back.
      That said with the slats off it may not be as critical...you may still be able to get a power off landing with a slightly steeper approach. I said "with our CG" because I didn't try it with the CG more forward, so I can only guarantee it works where we had it. If you're thinking of trying it with the slats off test it and see what it does with the bigger batteries if that is what you have...might work fine with the CG forward of where we have it. If not you can take the steps to get the CG back then or decide if its worth getting smaller, lighter batteries.

      Yep, that is what you have to do with the Bison to have slats that actually work like slats. Disengage them from the flaps and permanently lock them in the closed or "slat" position. The fact that they made it so that when you lower the flaps the slats rotate forward and become spoilers/air brakes is just ridiculous.
