150+ MPH RACING DRONE FOR UNDER $150 DOLLARS!00:00

Great video! That was flying!! Thanks for the maths ?

wow thats bloody quick, all those fancy motors they use in there how to build video’s, that cost 35 dollars au. cheap racerstar motors beat them all so far, well done.

I’ll probably go straight for 6s…

Hmm

You can get gps and return to home setup but it is kinda beside the point. Same with battery life.
You can get 3-5 minutes of battery life but at that speed it’s plenty. You generally come to the park with 10 or so batteries. It’s definitely an exhilarating experience and you crash a lot, especially learning acro flight.

@Randy Chilldres it really depends on your setup. Basic gear will get you 1km but I run a different frequency that can go up to 15km. Again kind of beside the point as it’s far more fun(and legal) to fly in and around trees. Have a look at some of my other drone flying videos.

Also if you want to get into the hobby jump on intofpv forums and ask around, my username on there is “bffigjam”, we can show you everything required to get setup.

What do you suggest for a controller and goggles? Not looking to break the bank

@daveefordays Thank you! Have you thought about doing a build guide at all?

Did you have to solder the FC and VTX to the frame?

@daveefordays I suppose I meant did you have to do any soldering at all? I want to make one myself but I don’t have a soldering kit or tools in general. I also don’t think I can afford to spend much beyond the $150 on tools but I really want to try to build a drone like this one. This particular model might be a little too ambitious for a first build but I want to go all out. Thank you so much for the links and video!

Can you show us how did you build that

daveefordays are you putting a throttle limit or just 6s with nothing at all?

Check out my 6s drone 70amp 2750kv motors that show over 150mph on gps with no issues.

I have never flown a race quad in real life, but I have 400 hours in the dcl sim. Would you consider this to be a good purchase for me?

You should put a throttle cap or get the lower KV. I will be trying them on 6S with no throttle cap soon.

What is the esc and propeller.

The high KV basically simulates 6S.

I have tested it multiple ways, including a radar gun and got similar speeds.

Probably 3 minutes.

@daveefordays thx great flying. Please upload more fpv videos

@Annika B it pulls about 180 amps, it is very light though. Only 400g with a battery

That’s truly amazing! I would love to build one (maybe with a 60A esc) and also it would be awesome if you could show as how it handles 6s! Actually i was thinking that a 5 inch toothpick frame such as the betafpv x knight 5 would give it better speed, acceleration and flight time in comprise of durability. But if it crashes at such speeds maybe durability isn’t worth it…

Please show as more about this project!

@daveefordays plz

Toothpick stuff is surprisingly durable IF your motors are lighg enough. Lightweight small motors don’t have as much torque, but they rev faster and cause dramatically less damage in a crash because weight at the motors is what causes lots of the damage in a crash. I highly recommend looking into high rpm smaller motors with toothpicks. You can go even faster than 150mph with the right setup. “deez nuts” brand lock nuts are also excellent for small motors because they are half the weight of normal lock nuts. This means your low torque smaller motors can actually reach a higher rpm and overtake the big motors with their lower rpms. Using the right props is important too. I’ve made 3 and 4 inch toothpicks that were this fast by taking advantage of small motors and high rpms with extreeeeemely low weights in conjunction with proper props. Both my 3 inch and 4 inch have around 18:1 thrust to weight ratio and are extreeeemely fast. Lookup “green light” on rotorbuilds. That was a 4 inch i built and sold. My 3 inch was arguably more impressive but I sold it before I posted the build.

@Xaris Rig There are so many ways to come up with the speeds you are looking for. Big motors and heavy drones aren’t bad, but they can do more damage to a frame or to someone’s property in the event of a crash. Personally I chose the ultra lightweight approach mostly because I wanted all my drones well under 250 grams for legal reasons. When I built them they were under a different set of laws because they were technically considered “toys” based on their weight despite being able to go over 150mph in seconds. My setups can’t fly for shit with extra weight like a go pro though. They will still fly, just not well lol. The same is true of super aggresive props, they just don’t do well since I’m already using undersized motors. I use cobra 1407 in my 4 inch, which is technically a 3 inch class motor, but they are 4100kv and put out 900grams of thrust a piece with the 4 inch props im using. This totals to around 3600 grams of thrust on a 208 gram quad (this is AUW including batteries and strap etc). The 1407 cobra motors can do aggresive 2 blade or really mild 3 blade props but anything else is wonky. Even with the right props, my setup absolutely has to stay under about 240-250 grams or the cobra motors won’t be able hit full rpms. With big powerful motors like in this video prop selection is still an issue, but MUCH less so than with undersized motors like I use. That said, setups like mine can turn a hell of a lot better, they ARE harder to fly though. I mostly built and sold them. I’m honestly not skilled enough to fly that shit all out lol. Don’t really want to break something before I can sell it lol. Edit: don’t forget to look up the light weight locknuts. Any motor can benefit from them. They hold GREAT despite being half the height of normal locknuts. Plus the brand name is just too funny lol. The brand is (no joke) “deez nuts”.

How would you improve the video feed, maybe a better camera or vtx or goggles

Which controller do you use?

Sir size of props?

What brand your receiver sir

Yeah they are suprisingly decent!

@Oxidon there are many fpv 5” build tutorials out there 🙂
