  • Bonka 2200mAh 75C 5S
  • Dinogy 1800mAh 80C 5S

I'll be using 7inch and 6inch props :

  • DAL T7056C
  • Master Airscrew 6045 RS
  • Gemfan Flash 6042

I normally use CL Racing F4S on all of my builds but decided to make an exception for this build and instead used JBF4 v2 FC, it's basically identically designed flight controller (even using the CL Racing F4S firmware) but it's rated up to 240A and probably more suitable for this setup with 7inch props and potentially 4000mAh 65C 6S battery. One major disadvantage is the fact that JBF4 comes with no SD card reader for the blackbox, instead only onboard dataflash memory is used and at 16MB it's not very usefull (it can record only one 5min flight before it gets full and then it takes 15 minutes to download the log file).

AUW with GoPro Hero6 and 1800mAh 5S battery is 855g.
Built as a long range surfer it's actually reasonably agile quad even on a tight track.

Hey, have another question about your mic?
can you tell me how you wired in the mic with smart audio? I've always got static and a bit of prop noise but mostly just noise that is not usable at all. I've seen the schematics for adding a 100uF cap on the smart audio line? I've also got a RaceDayQuads Mach 3 1000mW VTX with mic built in and the audio. I'd figure the designers of that board would add the caps or anyting else needed for it to work without issue? but, I just get the same thing all noise. if the quads just sitting there armed you can here just fine, or if its just plugged into battery and not armed it sounds great too. wonder if you have any suggestions or advice?

thanks for your help,

thanks for all the info I appreciate it. that 100uf cap what voltage is it rated for? that I cannot figure out. and where to get one? would really help. thanks again for your time.

pete_oz   Feb 06, 2019 

btw. it's 100nF (not 100uF), I'm in Australia and this is the only one that local shop had in stock (this one is rated to 50V) : https://www.jaycar.com.au/100nf-50vdc-ceramic-capacitors-pack-of-2/p/RC5360

Offset   Feb 06, 2019 

hi thre, thanks for the link, I figure it was going to be a ceramic circle type, didnt expect it to be rated for 50Volts. sorry was just a typo on the 100nf, I appologize. appreicate your help and your time, I hope you have a good sleep. goodnight

hey, wanted to get your opinion on those Cyclone props? they look like they'd be better then the HQ 7" props. what are you thougts?
thanks again,


pete_oz   Feb 06, 2019 

those cyclone 7056 props are the best 7inch props, if you get a good sample that is. mine came all bent in all directions so from 5 sets of props I was lucky to pick up 4 props that are good enough to fly, but maybe it was just me unlucky with the package and shipping method. HQ 7035 are not good, very "flexi" and they flatten when you pin them up (high throttle). same goes for Gemfan bi-blades 7042. the only other reasonable prop is HQ bi-blade 7045 but only the carbon version.

Nice build dood, I wish these frames were either true X or stretched X frames I'd consider a 7" long build if they did. Wondering if you can tell me if thats a Mic or a Baro? inside that clear bubble with foam out the top beside the Crossfire Nano on the left side. appreciate your time.

pete_oz   Feb 06, 2019 

mic questioned answered above. in regards to Epic frames - I normally prefer true X, all my other long range quads and all my 5 inch quads are all true-X, regardless I convinvinced myself to try the Epic and was pleasently surprised with the flight characteristics, I now own 3 Epics (5.5, 6 & 7"). my concern was pitch stability in view of the fact that this is wide-X frame, but in fact it's not that wide, the width is only marginally longer than the length, it's actually very stable on the pitch (and it goes without saying it's very stable on the roll as well). the guy who makes these frames will not make true-X nor stretched-X in my opinion. he is a good guy, very helpful and you know this is a small family business, he works from home and has another job. he has no resources to make and support various differrent versions of the frame.

Beautiful build! I like the painted carbon.... need to try it out one day.

Can you post a picture with the battery plugged in? I like the idea of the rear battery connector

pete_oz   Jan 05, 2019 

I usually feed the antenna between the battery leads to prevent leads getting tangled in props, probably wouldn't happen anyway with short battery leads, but some batteries come with longer cables.

that looks pretty decent, thanks

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..

This is the 4th installment to my popular "Wizard Killer" series, and is based on the popular Wizard X220HV 6S. As usual, the goal was to build a substantially better quad, yet come in below the retail price of the BNF kit. Here are some of the improvements: Higher quality EMAX ECO 2306 1700kv motors Foxeer's top-of-the-line Falkor mini camera Eachine 25mw-1000mw Leaf VTX with microphone Tools This..
