Building 250 FPV Racer w/ SeeMeFPV Motors!

Postby Jimustanguitar » Sun Nov 01, 2015 10:55 pm

Not much to say yet, I've assembled a frame (the Tarot TL250H from BangGood) and I've strapped some gorgeous SeeMeFPV 1806 motors to it.

The rest of the build will have a Naze32 V6, Arris power distro board, DYS mini ESC's, and a TBD video camera and transmitter (open to suggestions, if you have any).

Here she is, so far!

Ditch the spinners and use nyloc nuts to hold your props on. Those spinners are usually horribly unbalanced and don't stay on.

Apart from that it's looking good :D

As with most projects, I moved it along a little further today by ordering parts :)

I'll spend it together in no time! Oh wait, assemble...

Looks like lots of room inside for all sorts of goodies.

One thing I'd mention is to make sure that you don't support the VTx antenna just by the brass fitting on the end. Support it by using a cable tie around the coax of the antenna. This means that when you crash, the antenna bends instead of breaking off the brass fitting (and possibly breaking the connector off your VTx as well). Just easier to know about this now instead of after you build it :)

Also build light, light is might at this size.

(Disclaimer, I've designed my own quads and have a kit for sale)

Yep, she'll be bare bones and lightweight to try and make up for the extra frame bits. That'll make me more agile, make a battery last longer, and also put less inertia into the crashes.

I'm going to solder up the naze board with only the headers that I plan to use, I'll crimp my own exact length servo wires, the motors will solder directly to the ESC's, etc. I'm also thinking about taking my receiver out of its case to make that lighter. For the VTX, I've got a 10cm SMA extension cable with a 90deg bulkhead on one end, but I haven't mocked it all up to see if the length is appropriate yet. I'll probably end up with my own RF connectors and making that custom length as well.

I've got a printed frame in the works that I hope to be flying in the spring, but this frame is just to get some of the components I've got sitting around up in the air quickly.

Hello Jim,

I was just in here browsing and noticed your build.
Have you had the opportunity to finish your build and have you flown it?
If so, would you please share your experience.
I am in the process of looking to build a Tri or Quad-copter and I have the SeeMeFPV motor package.
Thank you,
JC

I didn't finish this build yet, unfortunately. I've got all the components mounted, and the step that I left off on was soldering the motors to the ESCs with the right polarity. It's set, and works with the wires twisted and taped together, but I never got out the soldering iron to finish it...

Had fun with the Detroit Drones guys at the makerfaire this weekend, which made me drool over having a flying quad again, so this project will probably pick up speed again soon :)

Is anyone still active on this Forum. I been building multirotor's since the 8bit processors and Arduino programming. I never noticed a forum here . Heck the biggest reason I bought my printer was to print parts for my own designs and friends who need things for their stuff lol. If there is any way I can help please don't hesitate to contact me,I have a lot of experience with the newest equipment out today Email is Tafester@optonline.net :ugeek:
Currently I build an Race FPV Quads. I have a problem when it comes to RC stuff.I buy to much . :oops: I have and race Two 210 size, one 190 size, One 130 size (fastest) and a tiny Whoop with updated motors . I do own two sets of goggles, one set is Fatshark V3 dominators with laforge diversity and the others are Skyzones v3 . Its very hard to find the correct info out there today to help you make a good choice on the best equipt to buy. This helps so you can be a little more future proof and say on the front of the wave . My newest thing I am doing is making 5.8ghz antennas for the video link . I have had really good luck in the ones I have made so far for my buddies and myself. The more you fly the easier it gets .. FesterFPV . :mrgreen:

I'd be curious to know more about your Tiny Whoop. I've been thinking about buying or building one, but haven't picked out the parts yet. I'd love to hear your recommendation. Obviously, I can print a frame if needed, so the electronics are the bigger unknown.

How are you building your antennas? Are you printing a form to bend them on?

Yes I printed a few jigs and bend the shapes needed for the design of the antenna. As for the tiny whoop the frame is no concern of course ,but as for the Flight Controlller board I would run a F3 processor with Betaflight firmware . https://www.amazon.com/dp/B01M72IXMU if you use a spektrum radio this is a good board . I would sugest the higher Kv motors and this depens on you experience . The faster motors are harder to fly with and be smooth ,14,000kv for outdoor LOS or moderate FPV or 17,000 kv for crazy LOS or fast FPV or 19,000 Kv for insane punch outs. These motors are brushed so they do wear. There are so many mfg out there for these motors , most of them have the same performance .https://www.amazon.com/dp/B01M4QRVA1. If you really want to jump down the rabbit hole check this web site out https://micro-motor-warehouse.com/collections/tinywhoop hope this helps ...
