If you’re into flying the Blade Inductrix line of sight (LOS) and like doing “trix” like flips and rolls, then this build is for you! This is my third Inductrix LOS build and I think I finally got it right! Upgrades include a very lightweight carbon-fiber frame brace, upgraded 17,000Kv motors and high quality batteries. This build yields high performance with incredible flight times of over 5 minutes of extremely hard and fast flying!
Sure there are higher Kv motors available but with higher Kv comes increased Amp draw and lower flight times. I nixed the stock 10,000Kv motors and went with a set of Lumenier 17,000Kv purple can motors for a good mix of thrust and Amp draw. For comparison, a typical 14,000Kv motor draws 1A, 17,000Kv motor draws 1.5A and 19,000Kv motor draws 2A. The stock Inductrix ~10,000Kv motors draw probably 0.5-0.75 Amps.
As you may already know, weight is a deficit with these micro quads so anywhere you can save weight is a bonus. Ready Made RC (RMRC) currently produces the lightest Inductrix frame brace on the market today. It’s 0.5mm carbon-fiber and half the weight of any other Inductrix frame brace! In addition to being extremely lightweight, the RMRC Inductrix CF frame brace has a built-in battery “keeper” which keeps the battery in place while flying and bashing. I have flown 150, 205 and 220mAh batteries with this brace and all have worked well as far as positioning and CG.

- Weight: 0.4g Advertised; 0.368g Measured
Frame Brace Retention
In the past I have used heat-shrink tubing around the Inductrix airframe motor tubes to retain a carbon-fiber frame brace. This works okay but the tubing eventually slides down so you need to keep pushing it back up. This time I used a couple wraps of Permacel PTFE or Teflon 1/4″ tape. You could use pretty much any narrow or cut-down tape though.
Battery weight can be an issue. Sure there are 1S batteries larger than 220mAh but unlike Thunder Power Adrenaline 50C batteries, you will find many have inflated specs. For example, Tattu 1S 220mAh 45C batteries weigh the same and have almost identical flight times to most 205mAh 25C batteries. Thunder Power 220mAh Adrenaline 50C batteries seem to have a true capacity rating because they actually provide longer flight times than 205mAh batteries.
