Race vs Freestyle Builds: Discussion40:30

Most informative video i have seen in a while?

I think he said our technology isnt good enough for physics to matter?

It seemed frustrating for the racer kid. Everyone kept talking over him. Meanwhile I imagine he felt that he had to answer to numbers not opinions.

I liked the part about how longer arms give more leverage and slow down the response, in my case gives me more control. My experience as an inexperienced flyer is that most of what the industry has settled on doesn’t work for me. I make my own frames from crashed quads and parts kits and I typically end up with 240-260 mm for 5″ machines. 220-210 are too twitchy. I can successfully fly a 250 with 5″. Taking the exact same quad and extending the arms 10mm in each direction doesn’t change the weight much. With stretched-X (it sort of came out but I don’t think as definitively as I experience it is that) by lengthening the pitch axis they’re getting more control/resolution of the throttle.

If any frame makers want to pay attention to what this avid but less skillful flyer needs is very light slightly larger builds. My own machines are 300g (without HD) and 250mm. For me lighter and larger with the same power are what’s more durable and more flyable. The industries offerings don’t work for me.

I LOVE F.P.V.

” I disagree with both of you” proceeds to make the same points both of them made

Has anyone have an opinion on the ImpulseRc helix frame?

Great discussion guys. Thanks. There is still a lot of personal preference involved and much of it is subjective. I learned a lot from everyone’s different approaches and ideas. I now have some new things to try.

they should fly alex his racing copters ! i think bottom mounted lipos with a go pro on top of the frame are extreamly fun to fly freestyle with it ! other than that i am a racer ;D

I seriously don’t get the people who say Vanover’s acting cocky. The guy has the wins to prove what he says carries some substance. Both Stingy and Zach were talking down to him and disregarding the experience that he has gained. On smaller tracks, the cap’n has the skills to zip around with an under pitched prop with a lightweight setup whereas a heavy setup would help a pilot with lesser skills. I would rather listen to someone who wins actual races than the others with regard to racing. Very valid knowledge on the freestyle side of things dropped by Zach and Stingy.

Captain Vanover looked soooo bored!!

Love how logically Joshua explains details. Thanks for this discussion guys!

I feel the kid doesn’t make sense

more challenging doesnt mean slower, but easier has its benefits! if you control it through the small space youll gain/keep more speed but i understand its a balance, different for everyone. i like the downpitch the prop solution for that, simple functional. i think hes got the right idea.

What are the excact specs of Alex’ race quad?

I have learned so much from you guys and some others in the last 5 weeks. I have been taking my time with my actual build. with that being said…I have LOS dialed. happy with my acro progress via sim. I can fly. likely I will have my first two builds done and flown before summers end. much appreciated yallz

What I want to know is why line of sight freestyle guys use the battery under strap while FPV freestyle likes it on top ;O

Wow you guys only lightly touched on the main difference between freestyle and racing quads like one time. You didn’t even make it a subject…

Where you mount the battery. You touched on it a little but it was to bulster another point you were making. I was imagining that one of the main points would’ve been where the battery is mounted…. but you guys never even really talked about that at all which is very strange.

When talking about the different frame styles, takes me back to my days of archery, where a long rod (stabiliser) with weights on the end would effectively slow down your movement of the bow when aiming, more weight as long as your strength and endurance can handle it mean’t essentially aiming became less twitchy and easier to hold on target.

Same physics principle regarding arm length and stretched X frames etc.

for durability, you should have asked cricket ??.

YES around 13 minutes in the guy talks about how efficiency. I recently took my 3 inch down from 3052’s to 3028’s thinking i’d get more battery life, and instead what happened is that I got A LOT LESS battery life! I needed more throttle to hover, the motors had to spin much faster, I even had to increase filtering because the motors were getting too hot. It was very surprising but in the end made a lot of sense.

So to summarise the difference is basically the energy required to change the momentum of the quad-copter, the faster you change the state the less efficient it becomes but in certain applications you need a faster state change so its about optimising the energy required to do that.

ask Zoe

and here i am building 3d Freestyl quads with 500g

It’s nice to see people get really animated and excited about flying… I think I’m going to gravitate to wherever I find the excitement going on… because that’s where the action and innovation is happening.

Awesome discussion guys, It is an educational experience from some of the best FPV pilots out there! LTRIP!™

Racer Dude in the middle is cringing at all these heavier frames on certain tracks discussion?

When is your camp coming to San Francisco

old guys: Our math and theories say blah blah blah blah Young kid: Hold my beer old guys

100% best vlog loved lots of great tips,lots learned thx rr

At 14:05 Vanover is like aah there he goes again…

Momentum of a heavy quad will carry speed better than a little quad. Also glide factor of the belly pan of body can increase float.

Fantastic video. Thanks for such a great discussion.

moment of inertia increases by square, while “force” moment is linear. ie a 2x the width comparing only motor weight/position for trust, will yeal 4x of inertian of the original and “only” twice the moment.
