Do you know the weight of the aluminium top part (the canopy) with its screws and standoffs? Without the carbon base frame. Thanks!

cjdavies Aug 13, 2018

No idea I'm afraid & I'm not planning to pull it apart to rebuild it quite yet!

I'm trying to design my first build and I am thinking about putting these 1408 4100kv motors on the 145mm GEPRC frame. (http://geprc.com/product/geprc-gep-gr1408-4100kv/). I also want to run the runcam split 2 with a 850mAh 4S battery. I'm assuming those motors would give me more punch power, but I do not know as I have never built a quad yet. Is this possible/would it be worth it?

cjdavies Nov 10, 2017

I'm no expert on 3" builds, but I think the consensus is that 14xx is more 4" territory than 3", unless you want to run really heavy/aggressive 3" props (which might give you more punch, but wouldn't necessarily fly as smooth nor as long). These 1306/4000 certainly aren't lacking in punch (

) while still getting a good 5 minutes on an 850 4S - & apparently these Emax ones aren't even considered that good anymore as 13xx motors go!

theAdimal Nov 11, 2017

Hmmm, i'll take your word for it. Those 1306/4000 look very nice and i'll probably run them now. Thanks!

I was tempted to build that frame. It's pretty unique and GEPRC makes a quality frame for the price.

cjdavies Oct 15, 2017

I was pleasantly surprised by the quality, especially considering the pricepoint. I'm still amazed that a 36mm stack with bags of spacing between the boards fits in so easily, it really was a breeze to build.

Whiffles Oct 16, 2017

Yep, it looks to have plenty of space. It would probably be a very good candidate for the Runcam Split.

TransTEC Laser S - How to build a 6S FPV Racer

27 days ago

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..

Wizard Killer X220HV Mark IV - 6S Freestyle on a Budget

Apr 17, 2019

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..
