An in­door mi­cro FPV with out­door per­for­mance

The mi­cro rac­ing craze has taken the first­per­son-view (FPV) world by storm. These amaz­ing lit­tle ma­chines, as ex­em­pli­fied by Blade’s In­duc­trix, turn your house into an FPV race­course, and they’re so light that it’s prac­ti­cally im­pos­si­ble for them to dam­age any­thing. The only two is­sues with these ad­dic­tive lit­tle quads are that they can ven­ture out­side only in calm weather and flight du­ra­tion is rather short. With the new up­size In­duc­trix FPV +, Blade has ad­dressed both these is­sues: The quad is fast and pow­er­ful enough for out­door rac­ing, and a 500mah Lipo pushes flight du­ra­tion up to six min­utes.


The In­duc­trix FPV + takes the orig­i­nal for­mula and stretches it to a 75mm size (mea­sured di­ag­o­nally be­tween mo­tor shafts). Power is boosted by 8mm mo­tors and 40mm props, and a 500mah Lipo of­fers about twice the flight du­ra­tion. The frame has added re­in­force­ment for greater dura­bil­ity, and the cam­era is tilted slightly for a bet­ter view­ing an­gle in high-speed flight. One other nice tweak is that the channel but­ton has been moved from the top of the canopy to off-cen­ter, so you can no longer accidentally change chan­nels by bump­ing the ceil­ing.

The In­duc­trix FPV + sup­ports three flight modes: Al­ti­tude mode, in which bank an­gle is lim­ited and the quad will hold al­ti­tude and self-level when the sticks are re­leased; Sta­bil­ity mode, which lim­its bank an­gle and is self-lev­el­ing; and Agility mode, in which bank an­gle is not lim­ited and the quad is ca­pa­ble of acro, such as flips and rolls. There’s also a handy “Meow” mode: If the quad lands in­verted, you can dou­ble-click the bind but­ton and two mo­tors will give a quick burst of power to flip it up­right. What a great idea! No more walk of shame!

The FPV + is avail­able in both RTF and BNF ver­sions, and pro­gram­ming is so quick that you can have your trans­mit­ter ready be­fore the in­cluded USB charger has the Lipo charged. Ex­tra bat­ter­ies and spare props are in­ex­pen­sive, and lit­tle else is ever likely to break.


It’s im­pos­si­ble not to com­pare the In­duc­trix FPV + with the smaller orig­i­nal In­duc­trix FPV. With its slightly heav­ier weight, the for­mer per­haps isn’t quite as nim­ble and for­giv­ing for fly­ing in re­ally tight spa­ces, but it com­pen­sates with greater power and speed and some in­ter­est­ing fea­tures. If you bump a wall, the FPV + will re­act with a quick burst of power to keep it from drop­ping. It’s fast and pow­er­ful enough for out­door fly­ing, even in a breeze. Best of all is the im­proved flight du­ra­tion; whereas the smaller In­duc­trix is con­strained by its tiny Lipo cell, the 500mah cell of the FPV + can stretch du­ra­tion to more than six min­utes. Im­pres­sive! The 600TVL cam­era and 32-channel 25mw trans­mit­ter pro­vide good video qual­ity and suf­fi­cient range for fly­ing through­out the house and


even out one door and back in another.

Al­ti­tude mode is in­tended for be­gin­ners; you can set the al­ti­tude by tweak­ing the throt­tle and then leave it set that way while you gain fa­mil­iar­ity with the other con­trols. This works well if you leave the throt­tle alone, but if you make a power change while turn­ing, it will abruptly change throt­tle try­ing to find the new al­ti­tude set­ting. In our flight test­ing, Sta­bil­ity mode of­fered the smoothest han­dling, and it’s docile enough even for low-time pi­lots.

In Sta­bil­ity mode, the FPV + tracks well in for­ward flight. Com­pared to its smaller sib­ling, it’s more con­trol­lable in steep de­scents, such as div­ing down stair­ways, and it has a lot more punch for rapid climbs.

In Agility mode, the FPV + can do ba­sic acro, such as flips and rolls. With no self-lev­el­ing, you have to be able to fly your way out of these ma­neu­vers, but you can click back to Sta­bil­ity if you get dis­ori­ented. The in­creased horse­power shows when you’re do­ing acro; it just has a lot more pop. In Agility mode, the top speed is much faster; it can re­ally scoot.

Land­ing is eas­i­est in Sta­bil­ity mode, but hey, it’s a lit­tle quad—if you just re­duce power, you can hardly go wrong. Af­ter land­ing, you need to click the bind but­ton to kill the mo­tors.

The FPV + is a load of fun, and my friends and I reg­u­larly meet at one of our houses for rat rac­ing up and down the stairs. While high-qual­ity gog­gles, like my Fat Shark Dom­i­na­tor HD3S, add to the ex­pe­ri­ence, you can have a ton of fun with a low-cost...

The In­duc­trix FPV + doesn’t look that much larger than the orig­i­nal In­duc­trix, but it weighs al­most twice as much. The boost in power from the 8mm mo­tors and 40mm props is dra­matic, but both ma­chines are en­joy­able in­door fliers. The FPV + is a faster...
