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).

Crashability
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)

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

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

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

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..

The iFlight XL5 V3 is a fantastic freestyle frame for the price. It features chamfered edges on some very nice quality carbon fiber. My goal for this build was to use high quality components at a relatively low price. Not only that, but I managed to reduce the number of solder points to the bare minimum. I've never built such a plug-in-play quad! The flight controller has an integrated VTX and doesn't..
