Hobby People F450 Quad DIY Starter Kit
I'm getting this HobbyPeople quad.
Has anyone have experience with this model?
|May 10, 2014, 02:22 PM|
I'm an old timer RC Sailplane guy, and I decided to educate myself about quads by building the Hobby People f450. I wasn't patient enough to order online, so I went to the store and bought it. I have spent the last couple of weeks putting it together, and here is a log of my build.
First, the kit should come with the Power Adapter, but it is NOT included in the package. You can't get past step 3 of 11 in the instructions without it, and to not include it in the kit is a crime. I had to go back to the store and of course it was out of stock and I had to wait a week, and then when I got it I realized later you ALSO need a mounting kit. I can't believe the mounting kit is not included with the adapter. Rather than go all the way back to the store, I figured out a way to mount it with zip ties, but still, this omission on the part of Hobby People is nearly unforgivable.
So with that, here is a look at my build...
First, attach top frame to struts. I am keeping the White struts as the FRONT of the craft and the Red struts as the BACK (makes sense, headlights and taillights, right?)
Flip it over and roughly attach ESCs. Keep them close to the access holes in the frame. I moved them closer after this picture was taken, and zip tied around the ESC, rather than the wire.
Flip it upside down again, and insert the Power Adapter and attach the power cables from the ESCs. Make sure the order is correct.
Rather than attach the board with a mounting kit, which was NOT provided, I used 4 zip ties inserted through the connection holes and through the frame.
Then slide another zip tie onto each of the first ties. Notice at this point I labeled each ESC with its correct number (and the eventual rotor direction) with a Sharpy so I didn't need to keep looking at the documentation to remember which is which.
Pull the zip ties tight, clip off the ends, and it seems to hold the power board fairly well. It's not super tight, but the battery will eventually squeeze in under the board and hold it firm. It would probably be best if they just included the mounting hardware WITH THE BOARD, and included the board WITH THE KIT! (curse you, HP!)
ESC cables attached to board. Be careful with polarity!
Attach the motors. The wires hang out to the side.
Solder the pins to the ends of the wires.
Put on the shrink tubing, and then you are ready to attach the motors to the ESCs.
Put on the bottom plate of the frame. Attach the flight controller to the top with the double sided tape. It fits perfectly between the zip ties!
NOTE: I have no idea if this is the right way to wire up the controller, but I think it is correct:
ESC 1 - White
ESC 2 - Grey
ESC 3 - Green
ESC 4 - Orange
are plugged into the bottom corresponding pins on the controller.
The double connector with the Red and Black wires is plugged into the middle and top pin of ESC 5, to hopefully provide power for the controller. CAN ANYONE CONFIRM THIS (while I wait for confirmation from the People at Hobby People)?? This is not clear in the documentation. Nobody at the store had any idea so I called HP headquarters and left a message. This has been the biggest mystery of the whole project, and I still don't have an answer.
With a battery inserted (it BARELY fits, and is held in place with an additional velcro strap), and the props lightly placed on the motors for a photo-op, the thing is almost done. Now I just need a radio and receiver. Basically we are done with the kit build.
Monkus the Test Pilot patiently waits for the final clean-up, calibrations, and radio instructions...
Basically this seems like a solid build so far. The kit, the power board, and a 3S 2200 mAh battery all together cost me about $250. Not too bad. I have no idea how it's going to fly, but when I get the radio going and get it all set up I will post an update. Happy Flying!

InPhase we're both doing the same build, cool!
I've experienced the same issues like you have with circuit board and mounting screws.
I used small mount screws from HomeDepot. Also I added CD holder as housing on top, then got aluminium rod and wooden skid for landing gear. Not maiden yet due to problem binding Rx to Flight Controller. Hopefully will get fixed. Happy flying!

Nice canopy! This kit definitely allows for customization, and the ability to do things in different ways. I almost bailed completely on the idea of the power distribution board, and was going to just solder all the wires together, but then it occurred to me that I will probably be upgrading the ESCs and controller fairly soon, and the circuit board will make that easier down the road. My only expectation for this machine is to get it airborne. If it takes off, hovers, and then lands successfully, I will be happy.
Do you think my wiring at the controller is correct?

InPhase, I have another thread here that speak of my issues (and solutions).
Basically, here's what I've learned from building this quad:
-Follow manual/direction precisely on calibrating ESC, flight-controller.
-On your transmitter; high/low rate MUST be set to HIGH or will not bind.
-Set the DIP setting (3,4) to match what your receiver is using (mine is set 3,4 ON for OrangeRX R710 - DSMX)
-Transmitter check on f/c by press and HOLD on "set" button on f/c.
-Make sure you calibrate the f/c (throttle up, left, HOLD) on level ground.
My maiden flight #1
Adjusting trims and trying out hovering, yaw, etc.

Finally got the machine in the air, thanks to the friendly people at my local Hobby People store. They helped me get the settings correct on my transmitter (needed to reverse the aileron and rudder). The first few test flights were rough. The gain setting on the controller was set too high, and the throttle was impossible to control. This led to a pronounced yo-yo effect. I turned the gain way down in hopes this would make it easier to control. Instead, this led to a crazy wobble. I was very happy to have the help of FPV Guy, Bo Lorentzen (www.fpvguy.com), who helped me dial in the correct gain and trim settings and suddenly the thing flew like a dream. Thanks, Bo!
At long last, my brave test pilot, Monkus, took the thing into the sky for its successful maiden voyage...

Yes, I think the Flight Controller is the weakest thing in this kit, but it seems to be doing the job, at least. I wish I had more control over the parameters. I forgot to mention the other weak link in the kit: the props. In my first test flight, the original props were making an annoying warbling whistling sound. I traded them out for better, sturdier props and the warble went away.
My next step: Replace the monkey with a FPV system, and put myself in the pilot's seat.

It seems we're doing similar things. I also got fpv system(ReadyMade 1.3ghz) ready to mount. But I've decided to get a bigger H-quad to put all the gears; and the distance between my FPV video Tx and 2.4Ghz receiver Tx would be good.
I think if I had to do over again; I would gone different route then the HobbyPeople quad. But it was learning experience. Good luck with your progress!

There was a small manual that comes with this flight-controller; check that.
Also the DIP switch setting must match your receiver type.
