I feel like subscribing to your channel was one of the really good decisions for my progress with the racing part of the hobby. Yesterday was another practice day and I was totally overwhelmed by the quad's power in sharp turns. Now I know what to do to start tightening those lines up. Thanks a lot for sharing and keep up the good work!
I think for those of us who aren't as fast, the added resolution is really the benefit on offer - 20% more throttle resolution for pilots that are still thrilled about finishing each heat they go up in is going to be a pretty noticeable improvement in results, especially for race formats that favor consistent finishes under pressure instead of getting one mistake-free heat. Particularly for use weekend warriors, that's going to mean less crashes that are going to put us off our game and cause second-guessing abilities on a race day - the intangibles are definitely in favor of throttle limiting, then if feeling good do the same process of gradually bringing them up to get more pace.
I think that running throttle cap from 50% to 100% will help pilots find their lines, but in the small local races, there are not enough practice sessions to take many packs on each throttle cap.
Great video John E, this is something I've had reasonable success with myself - there were a few first gate incidents due to the extra power on starts though, so that's worth keeping in mind. That aside, I can think of a lot of pilots who would benefit from taking this approach - they all look at me like I'm mad when I tell them I'm capping the throttle, more power = faster in their minds.
More power equals a quad that goes faster... doesn't mean it gets around the track in less time :). I don't think people really appreciate just how important race lines are in FPV racing at this point. It'll come though... What do you mean by first gate incidents though? That others have more power, so while you may get the jump on the holeshot, you had mid-airs because they are faster in a straight line?
@@JohnEFly we usually fly fairly small tracks and with mixed ability heats so it's good to get the holeshot and stay out of trouble, problem comes when the first gate is really close to the start line and you've just increased your throttle - I found there wasn't enough time to both adjust to the new limit and to get the holeshot, so I was either hitting the top of the gate or over compensating and hitting the floor lol
I don't think I'm going to make a video dedicated to the Floss 3.0L. But I do plan on doing a video about my entire setup, and why I chose the components that I did. That will, of course, include the Floss 3.0L as part of it.
Not to be poking the bear, but why were there no runs done at 90%? It isn't mentioned why. Just seems like it is inclusive data to not include any 90% throttle cap runs and just going straight from 80% to 100%. Was it an issue with the Spektrum radio where only certian outputs could be done? Or was there an outside factor that is not mentioned? (Limited flying time etc). Will say, throttle caps are a good learning tool as mentioned towards the end of the video. I'd say definitely use them for say, a UTT track or similar when learning the course, or if deemed necessary at a race.
Thanks for the info! I’ve really never thought about it on a 5” but now I’m seriously considering it. I’ve done it on my toothpicks but not on my 5” racers. After yesterday’s race and knowing now that I can finally hang with the big boys in the open class (3rd place overall yesterday woohoo!!) I’m definitely going to start training a lot harder than I have been. My internet has been sooo slow. I started uploading dvr yesterday(Sunday 10/6 at 4pm, here it is Monday at 9am and it still hasn’t finished. Lol.
I did it through the radio, so I can't say I compared them all and determiend the best way. I also can't comment on the available methods within FlightOne. However, I would assume that limiting throttle input (not motor output) would be the best way to apply a throttle cap. And it would probably be ideal to change it on the FC so have maximum resolution from the transmitter, but doing it on the FC is a WAY bigger process if you plan to keep changing it, so that's why I did it from the radio.
John E Fly gotcha. 👍 I’ll mess around with it. I know there’s a few ways to do it on the radio and I know there’s a spot on Flightone that you can adjust it but I’ve never played with it. But watching vids now on setting a cap and I see that even the way I did it on my toothpick isn’t the right way lol. I just basically lowered the end point on the throttle which did drop it to 80% but it seems like it didn’t do it the way I was thinking it would. I did mine Similar to the way that Justin skinner did on his throttle cap vid. It works but not the best way to do it.
@@JohnEFly If you're trying to run high-KV high-voltage, I'd run the FC motor out limit in addition to the transmitter - e.g. setting an 80% motor command out limit, and 70% transmitter limit on a 5S 2600KV or 6S 2250KV setup. I personally rely on the transmitter since it's easier to make changes on the fly, and I don't have to be powered up or have a computer in the field to reliable see where the limit is.
Did you run the 100% at the end of the day? If so maybe this means you were pretty well trained on the track -> you expect to have better times at the end of the day. Also consistency could be more important than ~1s improvement. I track mistakes and crashes too not just lap times.
Great Research & Analysis. Thanks for sharing!! One Question: Why did you skipped 90% :O ? 2nd. question: What do you think about mechanically limiting your throttle stick? (either by getting the famous red racing gimbalsl, or using a 3d printed limiter and re-calibrating your throttle)
Thank you! I'm glad you found it helpful. Regarding your questions: 1. Primarily because we ran out of time. By the time I get off work and get to the field there is very little sun. We just didn't have time to include 90% testing like originally planned. It would have been a good test, but at the same time, I feel like 80% is already pretty close to 100% for me, the difference with 80-90 and 90-100 is less than the difference between 50-60 60-70 70-80... 2. I'm actually a fan of limiting the throttle travel. Assuming you also calibrate your stick travel within your radio so you are not losing throttle resolution. The IX12 actually comes with a restrictor on the throttle now so it's a shorter throw by default. After trying that on the IX12 and really liking it I switched my Taranis to the red short throw gimbal as well. I feel like I can get added throttle response by having a shorter throw.
@@JohnEFly great!!! Will try soon to print some 3d part to limit the throttle travel and calibrate. If I like it (which I think I will), I will buy the red short throw gimbal as well. And will also try limiting the throttle to see if I can enhance my movements. Great contribuition man!
There are many ways to do it. If you have a Taranis there is a good video on Heart of America on how to do it. You can set it in Betaflight if you use Betaflight using a throttle limit and scale. Or you can do it like I did with Spektrum by going into the "Motor Curve" menu and changing the 20% 40% 60% 80% and 100% throttle positions to mean different outputs.
Do you scale the throttle or clip it? So at 60% throttle cap do you hit the 60% when your throttle stick is all the way up (scale) or at 60-100% stick deflection (clip)?
Im wanting to experiment here myself, was looking at how to make the caps in the IX12, are you only changing the end point to say 80% max, or are you changing all the points in the curve, so that quarter throttle is 20% instead of 25% when doing the 80 max. Is my questions making since, are you only changing the highest value, and not messing with the rest, or are you changing all the points in the curve to make it more linear?
It is scaling. It's just a difference in terminology I guess. But I did this via the transmitter and changed it so 100% on the stick was XX% output to the quad. I then updated all points so the curve remained linear.
@@JohnEFly I have mine set to a pot switch to change and another switch to turn it on. Some have it set so that it speaks the number but I just look at the radio and dial it in.
I would recommend trying this approach to force yourself to learn tighter lines regardless of your setup. I'm not saying you should race with a throttle cap, or that you will be faster, but it definitely helped me to be faster once I removed the throttle cap. On some tracks, I'm also faster with the cap. The best recommendation I can make is to try it, and then see if it helps you. Each pilot will be a little bit different.
There is nothing wrong with 2205. And honestly, 2205 is almost like adding a throttle cap to a 2207 quad and making it lighter at the same time. 2205 can be much easier to control, even though it lacks the top end potential. I raced 2205 for most of last year against mostly 2207 pilots and had a lot of success.
you are missing the point. The test should be a day on only 100% all day to see where you max out then try a day where you work through the caps. Also, I tend to start at 75% then just go up 5% until I feel like it's not helping anymore or I'm making too many mistakes. For me this ends up being between 85-90% which you didn't even test.
I think it's a bit tough to say I'm missing the point. My point here is actually to start lower than 75%. Flying at 50% REALLY forces you to focus on the lines. In this particular case I don't think I ever would have found the lines that I did if I had started all the way up at 75%. 50% required a whole different level of thinking, and personally I believe I benefited from it, making my flying at 100% better. Keep in mind, I'm in no way criticizing anything that you're doing. I'm not criticizing using throttle caps, or flying at a set throttle cap. I'm instead just doing testing of something that I wanted to see and sharing it with everyone.
TBH, there isn't improvement to be had above 95% anyway, so you're actually getting to that point. I tend to personally top out at 80-85% equivalent throttle cap performance in terms of overall race times because the consistency starts to drop off (I'll get a couple faster laps, and blow it, then recover quickly), so there's also some racecraft to doing that as well. I also rely (probably too much) on flying inherently slower setups early in the day so that I can work lines and be closer to the performance edge of the quad, usually with the benefit of extra battery life in practice.
