FlightClub Neutron Prototype : FPV Race Frame

You might be wondering, why is this PROton so small?  Well, that’s because it’s not a PROton.  This is the FlightClub Neutron.  The Neutron is basically a slightly smaller and slightly lighter PROton that’s designed specifically for the smaller 20×20 components.

It’s got all the features you love from the PROton, just shrunk down.

Specifications

* This is the v1 prototype so some things might change

  • CNC 7075 Aluminum Nucleus plate with threaded holes for the motor screws
  • Butter mount – will have custom butter mounts for M3 and M2 screws
  • at least 4.5mm arms
  • 5″ is about 210mm
  • Skeleton or Hybrid canopy.  The pod is designed by MayDay FPV
  • Skeleton plate has a slot for the PROton GoPro mount
  • Will have different arm options 5″ 22xx, 5″ 14xx, 4″ 14xx and 5″ SX
  • Goal is to get the weight around 60g.  currently about 65g

It still features the nucleus plate with threaded holes for the arms.  This will eliminate additional nuts needed to hold the arm screws and makes arm swaps a breeze.

Yes it has the butter mount also.  If you aren’t familiar with the butter mount, it’s a way of mounting the flight controller stack I invented that completely isolates the flight controller from any vibrations.  These custom butter mount grommets prevents any hard surfaces from the frame to touch the flight controller screws.  Since some 20×20 stacks use 3mm holes and some use 2mm holes, there will be a new custom butter mount grommet that will let you use the 2mm hole components.

It will have countersunk holes like the PROton for a completely flat bottom.

 

Just like the PROton there will be many arm options for the neutron.  There will be a 5″ 22xx motor pattern  and stretch X version later.  I’ve had a lot of people wanting arms for the smaller 14xx or 15xx motors so I made it for the Neutron.

This Neutron has the 5″ 14xx motor pattern holes with the Brotherhobby 1507 2800kv.  It’s using the HGLRC F440 40A BLHeli32 3-5s F4 stack.  The build weight of this one is about 175g and can use 5″ props.  4″ with 5s would be fun on this setup!

The Neutron v1 prototype weights around 65g, around 15g lighter than the PROton 5″ race.  It doesn’t sound like a lot but when you factor in the weight savings of using 20×20 components it comes out to around 30g less than an exact build but using 30×30 components.

These two quads are using the exact parts except for the stack.  The PROton, on the left, is using the RaceFlight Bolt32 with RevoltOSD and weighs 282g.  The Neutron is using a 20×20 RaceFlight Spark v2 ESC with MillivoltOSD flight controller and weighs 248g.  The difference in weight is 34g.  That’s like flying around with 1 less motor.

PROton vs Neutron

 

The Skeleton top plate (Neutron left, PROton right) will still have the slot for the GoPro mount.

The Neutron Nucleus plate (left) still has the threaded holes and butter mount.  It’s 2.5mm vs 3mm on the PROton.  Both are still milled out of 7075 aluminum.  I’m testing if 2.5mm is thick enough for the CNC plate.  Don’t worry, I know what you are thinking…”what if I strip the threads?”  Of all the PROtons out there, we haven’t heard of a single Nucleus plate with stripped threads.

Even though the PROton can use 20x20mm components, because of the placement of the arms, the rear two holes of the 20×20 holes need to use the arm screws.

So does this mean the Neutron is replacing the PROton?  No, I don’t think so.  Even though it’s smaller and lighter, 20×20 electronics are still pretty new.  PROton will still be the flagship race frame.  It’s about having options and having the right tool for the job.

This is the v1 Neutron prototype so there’s a lot of testing that needs to be done.  I’ve got v2 arms that are thinner, lighter and 5mm arms coming too.

Will you be adding a Neutron to your fleet?  Let me know your thoughts in the comments below.

    I will definitely be getting a neutron I tried to fit a 20×20 aio and found it really hard plus 2 of the screws were not butter mounted so the neutron will solve this as well as being lighter and smaller! So Mike do it bro !!

    • Mike Tseng 04/13/2018 at 6:13 pm - Reply

      yeah i understand. you’ll love this neutron. it feels a lot smaller than the proton

    Please no weird hardware like the chameleon. Std M3 screws only and 5mm arms. Thx!

    • Mike Tseng 04/13/2018 at 9:02 pm - Reply

      yeah everything will be M3 unless you are using a stack that uses m2 holes. i have 5mm arms coming

  14. Adam 04/17/2018 at 11:24 am - Reply

    Still seems heavy for 4 inch Mike, my 4 inch are mostly about 40g frames including metal and 3D printed. For 5 inch looking at light props even in the 2800kv, 2 blade 5040 glass nylon or carbon nylon work well on 4s with cobra 1407 3200kv, rotorgeeks 2800 and even 3200, 850mah pushes the flight time for a race at high throttle, but 1050mah should get you there.

    • Mike Tseng 04/17/2018 at 3:56 pm - Reply

      these are really 5″ racers that can do 4″. these scream on 5″

    Awww man! I just finished 3 Proton builds. Now I gotta get me some Neutrons too? Haha. The fleet is getting bigger every day! I am not sure about the v1 AXII mount you have pictured. I really like the v2 AXII mount on the Proton. Nice work on the new frame, Mike. Keep em coming.

    It’s too bad you couldn’t make the Neutron and Proton arms exactly the same. I would love the ability to just have 1 set of arms for both the frames.

    Do you know if the Neutron will fit a spark 32 esc mike?

    • Mike Tseng 04/17/2018 at 11:15 pm - Reply

      right now no, i’m really debating if I wanna design for those gigantic “20×20” stacks. those escs are about the size of full size 6s 4in1’s with 20×20 mount holes. why not just go with a full size quad?

      • Jeffrey Gustin 04/22/2018 at 9:44 am - Reply

        I think it would be helpful to use a 60g frame for a 6s build lighter componets can help with the hevey battery…. that’s the only reason I asked about the spark32… it’s prob just the back stand offs keeping it from fitting I’m guessing?

        • Mike Tseng 04/22/2018 at 12:49 pm - Reply

          yeah, that spark32 is not really a 20×20. that thing is bigger than a standard 30×30 esc. the issue is if I make the neutron fit those huge 20×20 stacks it will be the size of a proton almost

          • Jeffrey Gustin 04/22/2018 at 8:05 pm

            i got you bro.. i guess HGLRC Makes a 40 Amp ESC…

    I would love to see a 3″ practice version for around the neighborhood with 5mm arms.

    Hello Mr. Mike, very nice job! I really appreciate the fact that you are always on your game. You seem to always be looking for and or experimenting with new ideas for faster, lighter, more responsive, race winning, Super Quads.
    I, for one, really appreciate your build videos, which in my opinion are some of, if not THE BEST build videos On YouTube. Concise, Relaxed, no nonsense, well exicuted builds that are very consistent. I especially like the wire length cheat sheet. That’s “thinking out of the box” and I like it!! We need more Men and Women in this world that are as passionate about their field as You are! Great work!
    PS: curious if you are familiar with Kabobs latest “Drone theory” with the latest Floss frame. This may be geared more for “freestyle” Pilots but, im curious how this would fair on the racetrack. He was saying on his latest YouTube video that many of his R&D Test Pilots are having extremely improved handling, no prop wash and more by using 6” arms but, they 5”props. Obviously, just the props being a little further apart is gonna assure clean air for each prop. I’m curious of your thoughts on this subject. Sorry for the Novel but, the bottom line; You are the Man, keep up your great work!!! 👍👍

    • Mike Tseng 05/03/2018 at 10:43 am - Reply

      hey Lewis, thanks for the words! appreciate it!

      no not really, I don’t pay attention to what other frame designers are doing. i use to but then it makes it really hard to design unique quads. everything i drew up looked like some other frame i saw so I dont look at other frames anymore, ha

      yeah you may get less prop was but using super long arms will kill the responsiveness. really with the new software like butterflight, prop was is almost non existent. you have to really try hard to get prop was.

      I’m loving the smaller 205mm neutron with 5s or 6s. it’s the best of both worlds, small light quad with instant power/zero sag

    FPV FlightClub FTW! I will never buy from another company again. DTF vs bnf…. DTF wins! Set my radio up, downloaded files and I was in the air! However I did take a chance, as I needed a 3″ modular version to fly(noobs and crash alot) at home so I do not have to travel into town to practice, and again bnf has let me down… my first was the vortex 150…. had to send that one back with my radio just for them to get it in the air. I will be doing the same for this new bnf 3″ as well.

    I am so blown away Mike, with you and your company by the amount time you spend on answering customers questions. Also having served in the USMC/0311 I can appreciate “YOUR” attention to detail…. which is OUTSTANDING! My family is now FPV FlightClub for life! Thank you for making it easy for us noobs to get into this competitive hobby and it is my hope, as I have 3 man cubs, to fly with them together using FlightClub Machines! Thanks Mike…. can’t wait to see this one and hope you will offer 3″ arms for us neighborhood flyers. Just love the modular platform.

  21. Rocket 05/11/2018 at 2:36 pm - Reply

    Will it fit the flight one spark32 4-in-1 esc? I know its bigger than most 20×20 stack. But its currently the only flight one option for flightone users for 20×20. Looking at the pictures, it looks like the rear stand-offs will interfere with the power connection side of the board.

    • Mike Tseng 05/11/2018 at 7:08 pm - Reply

      most likely i wont make this frame fit the spark32. that board is bigger than standard 36×36 boards. why not just build a full size quad? you can use the spark v2 which is 20×20 and the millivolt. I have this in one of my neutrons and it works fine

      • Anthony 05/11/2018 at 7:16 pm - Reply

        Thanks Mike. I do understand your point. Kind of defeats the purpose I guess. Looks like hglrc f440 is my only choice for 5s. Do you have an ETA yet for when this frame will come out. I’m definitely interested in a couple for sure.

        • Mike Tseng 05/12/2018 at 9:32 pm - Reply

          It will be sometime next month. Still testing the frame. i’ll post something when i get the new prototypes next week

      • Anthony 05/12/2018 at 12:09 am - Reply

        do you have an ETA for release on the Neutron? I will definitely get a couple. Will probably be my go to lightweight frame for 2018. I really like the proton but I find that im wishing it was a tiny bit more compact and lighter. Neutron fits the bill perfectly. I was going to go for the xhover win5L, glad I saw this post….

    Will there be a true X version? or just stretch x?

    • Mike Tseng 05/11/2018 at 7:09 pm - Reply

      The true X will release first, followed by SX later

    How did the 6s fly go? Would be great to have options for a 6s setup (as 6s and low kv motors are the future)

    • Mike Tseng 05/12/2018 at 9:35 pm - Reply

      not good so far. 20×20 electronics are still fairly new. there’s not a lot of real 20×20 stacks that can handle 6s. i’m sure there will be a lot of new gear coming out this year for 6s

  24. detailedj 05/14/2018 at 5:50 pm - Reply

    I hear that .. would love to see a 6s video with this quad. 4s is old stuff later this year … going to be about 5 and 6s for the next year! This would be pure future proof and a nice racer out of the gate at 6s!

    Will F1 Spark32 and MillivoltOSD fit this frame? If yes then my trigger finger is ready for some checkout :D.

    • Mike Tseng 05/15/2018 at 12:10 pm - Reply

      no it wont fit that esc. that’s not really a 20×20, it’s actually bigger than a 36×36 ESC with 20×20 holes. why not just build a full size frame?

    Cant wait! I have a proton and a phukket. I originally wanted to get the proton for 20×20 but the neutron should do it. I have two different 20×20 stacks waiting for this frame along with 2204 hyperlight motors.
