My wood frame quad with kk 2.0

My wood frame quad with kk 2.0

My wood frame quad with kk 2.0


Specs:

Frame made out of wood
KK 2.0 FC with Ver 1.6 firmware with X motor layout
Avionic M2230/15 KV1780 MICRO brushless motor
Hk 20amp esc flashed with simon k firmware
Wolfpack 2200mah 35C 7.4V
8043 props
AUW 600gms approx
Getting 10mins of flight time in hover,5-6 mins in acro mode(still learning)

Well it took me 2 months to get it up, but major cause of delay were the props not fitting on the prop saver properly due to  slope on the prop savers, which caused the props to slip away. Smaller O rings dint help much.
Initially used fevicol to glue the props but dint work, feviquick too wasn't up-to the mark, then used epoxy which is holding on for now.

Went through this forum and various other forums on assembling and trouble shooting issues. Most of the info is out there easily accessible on searching (google!), so it couldn't get much easier than that.

Now i just had some questions:

1) Can i use 2 batteries in parallel with different discharge rates and capacity(ex 2200mah 35C+1300mah 25C 2S lipos)?
I understand that current output will be total of both the batteries, but 1300mah lipo will be depleted before the 2200mah lipo. Would that be a problem?

2) Would it be fine to use 3S lipo with these motors with an inch smaller prop?
I have no means to measure the current draw, tried the 3$ wattmeter on RCG but it isnt working in my case probably because of my clamp meter, altho the esc's are not getting warm with the current battery, yet i would like some advice/opinion.

3) I'm using a Hk V2 6CH tx/rx and there is a slight jitter in elevator and aileron sticks, such that i cannot exactly trim them to "0", they keep hopping by 1 or 2 +/- trims. Can i sort this out by myself?

Awesome simple quad!  Clap  Thumbs Up
Flight video?

I see you've used an electrical connector in between the motor, ESC and battery, I reckon they conduct atleast 10A continuous load, faced any heating problems? I wanted to use it in a project, I was too lazy to get one and test it. Cheesy

hi,

pretty desi style! Smiley
congrats for the quad...please upload some video.
you can check all the parameters about quad parts here: http://www.ecalc.ch/xcoptercalc.htm?ecalc&lang=en
one suggestion: make some vents below the motors to allow more flow of air and proper cooling of the motors.

lol, desi indeed,
budget and availability of parts led to this quad.

Anjan you are right, they are rated for 10amps but the shopkeeper told me they can handle 20amps, i took his advice with a grain of salt,however haven't faced any heating issues yet,but i don't know how much amps my motor are pulling so...
However they also had ceramic connectors, or something like that which can handle more current, you should check that out.

Aman i dont have all the data required to use the ecalc, altho i did try it earlier,
and if i drill more holes on that frame it may become very weak however i will try it on my next frame.

Right now i'm flying it on my roof, and im alone, will post video in some time, altho it flies well and is stable but wont hold position, but im working on it.

Thanks for the info, what are these connectors called, BTW? Cheesy

You could have tried the 3.5mm bullet connectors, they can handle upto 50A and much secure too.

I told them that i need "connectors", thats it,
and i needed 12 pairs of bullet connectors which wasnt available at places i looked, together, so i gave it a skip.
I wish small parts such as connectors, dean plugs, props, shrink wrap etc etc were produced locally/cheaply.

Initially i wanted to build a much smaller quad with an AUW of 300-400, but props were a problem, so was esc that can be flashed with simon k firmware. Anyways my quad is done so it doesnt matter for now.
