Throttle curves - No governor
Until spirit works on firmware to make the governor usable for nitro helis, I'll be running throttle curves. I'm a bit new to curves for nitro machines though.
Not interested in adding an external governor at this time because it would require purchasing not only a governor but a receiver, more wiring b/s, and more money - I'll just wait for firmware or switch fbl units in the future. Based on some manuals I looked at, throttle curves seem to be along the lines of linear for normal mode, 90, 50, 90 for IU1 and 100, 50, 100 for IU2 (of course, filling in the other numbers between mid stick and full deflection). Does that sound about right?

Seems reasonable to start with
But of course you need to fly it and fine tune the curves to make the rpm the most consistent as possible through all the pitch stick range. BR |

I don't run gov's on any of my nitros...had too many issues getting it set, main issue was glitches due to improper sensor/magnet setup. Pulled the gov- no more problems.
on my non-gov 90 I'm running the following vibe90 norm: 10%, inh, 55.5%, inh, 80% expo on Idle-1: 80.5, inh, 70.5, inh, 80.5 Expo off idle-2 90, inh 80%, inh, 90% Expo off raptor 90 norm: 12.0, 43%, 65%, 76.5%, 80%, Expo on Idle-1 85, inh, 75%, inh, 85%, expo on idle-2 90, inh, 80, inh 90, expo on I could have run 100% on my end points in idle 2 but personally I don't like to run 100%...just don't like running the engine all out- run a little cooler, a little less stress. I did run 100% but was blowing plugs too often, cut back a little and no more issues...I know, probably a tuning issue.

I fly a Trex 700N with an OS105 on 15% cool power.
It is very dangerous to run a nitro at 100% flat, way too easy to blow your engine, plus you have no room when you do load your disk. I run: IU1 90, 75, 70, 75, 90 IU2 100, 80, 75, 80, 100 this looks like a nice 'U' so I do not have a lot of RPM change around hover or basic sport, but when I want to throw it around I have the full power available. |

I stopped using throttle curves when the GV-1 first came on the market.
Get rid of the Spirit and get an MSH Brain. $120. All problems solved. You will spend at least $100 on the rebuild of the motor if you get it wrong. |

lets not get too hastey
Tice while I agree that if you blow a motor it will cost a ton I respectfully have to challenge suggesting the op scrap is fbl controller in favor of one you prefer, imo that is doing him an injustice. Besides we are more likely to blow an engine from poor tuning than a 'v' or 'u' throttle curve.
if he wants a gov. he can pick up an external one for ~$40, for the op's sake lets not get into the merits of integrated gov vs. external. |

I just sold my two MSH brains to buy the spirits. Don't remind me of how stupid I was to not do more research about the lack of a working nitro governor in the spirit. It's totally fine for electrics. Also, I just rebuilt the motor and haven't flown it yet, so the last thing I would want to do is go through another rebuild again. Sadly, I know that you're right, and that the easiest thing I could do is just buy another brain and slap it on the 700N for now, especially because I'm already familiar with them and setup would be a breeze. If spirit doesn't put out new firmware with a fixed nitro governor by the spring time, that's exactly what I'll do. I'm not selling my spirit pros that I just bought and haven't even flown yet though. That would be a waste of money, and honestly I'm over the brain units because they're a B**** to get the tail tuned. It always took ridiculous efforts to get the tails to hold on all of my helis, though the end result was good. I am not adding an external governor because for that to work with the spirit I would have to buy a receiver instead of using two satellites, combine that with the price of the governor, and I could just buy a different FBL unit that has a reliable governor. Not to mention all the extra stuff that I'd have to cram into the heli. Which is why I'm asking about throttle curves to use for now, as I'm confident that spirit will make the governor usable in the next firmware update.

MSH has a deal where if you buy a Protos Max V2, for $700, they "give" you a Brain (full size, plastic case) Some guys already have VBar or Skookum and don't want the Brain. I got three new "in the bag" Brains for $80 to $100 each |

The reason I got rid of the brains was because all my computers are macs, and I wanted something that has software for OSX. It was a pain to have to swap a harddrive with windows into my laptop every time I wanted to make adjustments. Putting windows on my main harddrive and having bootcamp or similar is not an option right now for various reasons.
Sure, they released the IOS app shortly before I sold them, but the freaking bluetooth adapter was $70. I have three other helis I can fly for now anyways so I'll just wait until spirit updates the governor. I really don't think running throttle curves is going to hurt anything, I can be conservative with the settings to play it safe.

Why couldn't you just use an imulator for your Mac?

It's not an emulator. You have to partition your harddrive, install windows on that partition, and then either run bootcamp so that you can boot straight into windows as an option, or use software like vmware fusion or parallels to run windows inside of mac osx.
Why can't I do this? Because I use both of my computers for work, the harddrives are constantly filled to the max, there's literally no space for me to do it, nor do I have the time to do this. Buying larger harddrives right now is not an option, as I need solid state drives and in a larger capacity they are still in the $350 range, and I just can't do that at the moment. I'll likely be upgrading my laptop later this year and the new macbook pro's use pci-e while my current one uses sata, so buying a larger sata drive now will be a waste of money since it won't be transferable into the new computer. And I certainly would not order a macbook pro with a large enough capacity drive from the factory because they charge absurd premiums on internal components. Running osx native software is the best option. I'm sure that some time in the future I'll have a windows partition again, but I don't know when that will be.

You could get a windows lappy used for way cheaper than a SS HDD. Just use it for windows only progs. Dont need to be anything special really

I could swap the FBL unit for the same or less money.
The point is that I don't want to invest in more stuff right now, otherwise the additional RX and external governor would be ok. I just bought the three spirits, upgraded servos on two helis, and some other parts so I'm not in any position to really buy anything right now. My next computer might just be a windows machine though, because apple has been on my last nerve lately. The added benefit would be more sims to select from as well. Thanks everyone that posted some basic throttle curve setups, I'll try those out.

you can always get a cheap laptop at best buy...like sub 500 cheap. Use it to do all your windows app's for the hobby. No reason to spend big bucks unnecessarily.
