Building Hybrids for fun.

Would this be a good balance charger for $30 dollars? It is the

Can I use a cheaper 2.4 radio I already have till I can get a better one? It came with a small hexacopter.

Ive not seen that charger till now so i cant report on if its reliable and accurate or not...Most like the Imax B6 charger from a reputable source..alot of fakes of that charger being produced.

For a hobby quad you need at least a decent radio ..i suppose you could use a cheaper radio if you wanted..the good ones are $100 and up however....As far as the radio you got with a toy quad copter ,i would have to say no, its not going to be usable with anything but the toy quad copter it came with or any other toy quadcopter using the same protocol.

Figure in these costs to build something brushless aside from frame cost

Electronic speed controllers...You need 4 of them at about $12 to $15.00 each.

Motors you need 4 as well at around the same cost or even higher...add in for 4 props and a few spares as well.

Programmable flight controller around $20 to $25.00 for a basic model like a naze 32 or a cc3d.

The transmitter you need to fly it properly figure about $100.00 or more for a decent one.

Now you have to know how to program the esc,s as well as the flight control board itself and set up the radio.

Dont forget about $40.00 for a decent charger and another $40 or so for at least 2 batteries.

Add it up and see what you come up with.

Or spend $60 $65.00 for something you only need to solder a few wires and remove a few screws on to build.

For a first build you could use a KK if you wanted to keep cost down, and the HKTR6a (I own one also) is a great transmitter for the price I have a better radio, but have never needed any more functions than this one while using the KK board. You can also use the simple hobbyking E3 charger (this is actually all I use for most my batteries).

Never seen it, but it is a DC only charger, you'd need a power supply, or a battery to charge it with. They are meant for charging batteries in the field.

The HKTR6a was what I was originally thinking of ordering.

If that is what you need to do to get in the air, then great, but remember to account from shipping and to get from the warehouse nearest toward you, and to buy everything at once (except maybe batteries).

After reading, found your information to be the way I wish to enjoy the hobby, currently I have a syma x5c, and a fy326. both fly well. I am torn, as I want to install the syma x5c board on the PFG 110mm frame, along with the syma x5c 7mm motors, once I complete that, I would then like to put the fy326 on the PFG 135mm frame with 8.5mm motors.

I would like to know what other quads run 8.5mm brushed motors, also I am a novice and want to build mostly micro quads in the 95mm-145mm range, with an eye toward, at some point, flying FPV.
Thus far I have just found these two quads.
Also, what of transmitters/radios though I'll ask about them next time, wish to have all of my quads on the same tranmitter/radio.....

A Devo 7E seems to be the go to Radio to control a number of toy quads but its not cheap..with each different protocol comes the need of yet another module installed onto the transmitter...Its not for a beginner in any way shape or form unless you can understand the programming and downloads needed to make them work properly and can install the modules yourself.

One guy sells them for around $150.00 already modded and ready to bind to a number of protocols but not all of them.

Choosing to use geared motors will disappoint you as they arent designed to be used in direct drive applications....If youre looking for affordable motors, any of the hubsan x4 motors in 7mm or 8.5mm would be a great choice or you have an option to use Chaoli motors at about $30.00 for a set plus shipping.....If this is what you want, the Chaoli 720-14 motors (7mm) would work great with the syma board and the 820-15 (8.5mm) motors would work well for your other project.

Hey ToyQuadBuilder, I am thinking of building a 137mm MMW Hexacopter, using the mjx x600, using 8.5mm motors, it has a7.4v power plant, and is called a "Heavy Lifter Quad". Question is will this configuration work for creating a real beast of a Hex, or will there be severe weight issues??
I plan to harvest all of the electronics from the x600, and fit as much aboard that 137mm frame..Thoughts, ideas, directions......
Also, which radio transmitters will have the models I mostly fly, in their system: I fly the Syma FCB for x5c, x12, the fy326 FCB and the jjrc 1000aFCB(coming). I see lots about the Devo, what are your thoughts??

 

[Mike H.]

Sounds like a fun project...As long as the size of the quad will still allow you to use the props i dont see an issue...Not sure what the size of the 600 is compared to your new frame...As long as the flight board and motors are 7.4v compatible i dont see an issue there either.

As far as weight, (as an example)..the more you can lose the more you can lift...If you can carry 50g now and you lose 20g then it becomes 70g....If your new frame is heavier by 20g then youll lose 20g of weight carrying capacity to make it 30g.

I wouldnt exactly call brushed motor quads heavy lifters however...The syma x8c is the most powerful brushed quad im aware of and the motors and props are more than an 8.5 motor and smaller props could dish out.

Again, the devo is the go to radio to control most all the devo compatible toy models...Not all of them are.

Im reading about more and more using the modules from the toy radios now instead of buying them aftermarket...If its a devo compatible FCB then it can be flown with the proper download and module with the devo 7e transmitter.

I have read a bit regards the Devo7, am interested in knowing which of the FCBs can be controlled by the Devo7. Also regards the mjx x600' it weighs 193g loaded, putting electronics in 15g MMW 137mm Hex frame with Parrot Rolling spider Props with that 700mah 7.4v battery, along with the 170FOV FPV camera, this should end up fast and manoeuvrable, thoughts?? Also any information finding which FCBs are able to be controlled......

 

[Mike H.]

You may want to check out the deviation site for a list of modules that work with certain models...Many quads can share the same module but not the necessarily same programming...Here is a list so far..not sure how updated it is however.. https://docs.google.com/spreadsheets/d/1nBHzT3VWF6ShAhOqRB5y0Bcc7aXFuRFFlQkHn1RIM84/htmlview#

What ever you can safely lift now with the stock MJX600, just add to its capabilities by how much weight you will lose using the different frame.

Rolling spider props are becoming more and more popular with custom brushed builds...if this is what is recommended by MMW then they should work fine.

Hey there TQB, flying the, both no problems to report, though am preparing them for cameras, your advise quite sound, so till at least the fall, I'll continue to simply, safely mod rtf cheap is, which does bring me to this; read at bit about a brushed to brushless motor signal converter allowing me to use brushed motors on cheap on with the stock radio, any comments on this, looking to purchase and experiment with the JJRC H8D, and the appropriately sized brushed motors, and thoughts???
