Short Description, Larger Canopy

I'm going to deviate from the usual long winded description and keep it short. Shown is the 20x20 canopy which was a little tight, so I made it a little larger. Now you can easily add a GPS receiver behind the camera (on the inside of the canopy with double sided tape).

So far the frame is proving to be a lot tougher than it looks and a huge improvement over the first version. Lots of crash reports from pilots, but only 1 (2 "spars") reported broken. This is due to the “Conditional Flexibility” which helps to alleviate the problem of shear stresses associated with rigid frames. In other words, the frame is allowed to flex only under high impacts:

  • During flight, a very high level of stiffness is maintained between the flight controller and motors for low mechanical feedback latency (this can be felt if you try to flex the frame between the flight controller and one of the motors).
  • Under impact ,when forces are high enough, energy is transferred to the center plates and perpendicular arms which are allowed to flex slightly to help diffuse the impact forces (this can be felt if you try to flex the frame between motors)

Any thoughts about the F722 mini? I'm thinking of using one for a build. Great looking quad!

Thanks! I finally flew a little more today, and yes - I would definitely recommend the F722

WHOOOHOOOO! I finally got to fly mine (Gemfan 6042's\F60 Pro III's\HGLRC FD445)! It took a little help from Ryan to help get me tuned, but WOW! It's like that first time you launched off the pad all over again!

is the cg better matched with the centre of thrust with inverted motors? if so, could that make it faster? also, nice build

The goal of this one isn't speed, although it is very fast. You'll have no issues breaking 100mph with just about any setup.

Wow this is really next level with the new canopy. Great work!

It's a pretty sweet canopy. Just enough room to fit everything and the quality is A1

That battery connector looks like the pony tail in that pootie tang movie and he deflected bullets with it and stuff. My friend thought he could deflect Billy clubs cause he knows karate so i threw dog biscuits at him and he couldn't even deflect those

You really are a gem

what KV do you run on 6s in this setup?

QuadStar Drones   Apr 12, 2019 

I haven't made the switch to lower kv motors for 6s yet. The only reason I have 6s is for speed runs with 2450kv motors

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..
