Changing to this will make it respond more accurately, but even with default +/-100 it should still work at middle to high range stick positions. It would be the same as you setting Min and Max in Outputs for ch 8 to +/- 78%. This is what Spektrum uses for their servos.

The pump directions says that full low (off) should be 1100 us, and full high (max flow) be 1900 us. If they are, then things are close in the TX and you should be getting the pump doing something. If they aren't changing, you have something wrong in Inputs or Mixing. So, first check - are the numbers changing as you move the throttle stick? Probably from 988 to 1704 with your curve, but don't worry if they are different, we just want to make sure it is sending something out! Default OpenTX defines 'Min' as -512, and 'Max' as +512, but shows it as +/-100% on the outputs page settings for each channel. At the very top of the screen you should see the millisecond pulse width currently being sent out on the channel, for different stick positions. Look at your Outputs screen on the radio, and move the cursor down so that Ch 8 is selected. All it takes is just one of those components to fail and it's DOOM.Never heard of the pump before, but a quick search and it looks like a neat addition for a multi-cylinder engine! Always assume that at any point during a flight any ONE component could fail resulting in 'death from the sky': A motor, a propeller, a speed controller, the battery, a connector, the flight controller, the receiver, the battery, the frame, etc. It's enough to kill someone and/or do very expensive damage to a house, car, or whatever it happens to crash into. A 450mm frame outfitted with a GPS, 2200mAh battery, and a camera can weigh 5-6 pounds and yet can fly well above 400 feet (actually ~5x higher but don't do that!). Always be aware of how much your quad weighs when flying. Stay safe: Charge your batteries in the bag and also keep them stored in the bag when not in use.Ĥ. They also go up every time you charge it. The chances are small, yes, but those chances go up every time you crash or if you let the charge of the battery get too low. Lithium Polymer batteries, sitting by themselves on the shelf, hooked up to nothing, will occasionally EXPLODE INTO FLAMES THAT CANNOT BE PUT OUT. Get at least one LiPo 'charge bag' (~$2).

The Taranis has basically made every other Tx obsolete and every Tx over $200 is now a huge waste of money.ģ. Not to mention one that does everything the Taranis can do (logging to SD card, audio feedback, jillions of switches/knobs/hats, etc). Before the Taranis, to get a Tx that supported even 12 channels was a $1200-2000 investment.

It runs the open-source OpenTx firmware (infinitely hackable), supports 32 channels plus a new bi-directional communications system named, 'Smart Port' (support for which was hacked into MulitWii by yours truly). The Turnigy 9X Tx (aka 'remote control' for the uninitiated =) is pretty good but the FrSky Taranis (~$200: ) is vastly superior. If you build your PVC frame with a 'T fitting' field repairs usually take just two minutes to swap out a broken arm (flamewheel repairs take forever in comparison).Ģ.

) or learn how to make your own frame out of thin-walled PVC (which really is super quick and easy if you have a heat gun-takes a lot more time using the boiling water method spend $20 and get a bog-standard heat gun). F330, F450, etc) get something that's much more difficult to break like a One-Piece Quad (OPQ) frame (. Instead of buying a cheap, easily-broken 'flamewheel' frame (e.g. If you're looking to get into this hobby I highly recommend a number of things instead of just putting those items in your shopping cart:ġ.
