I also have a GV1 but have read only good stuff on the TJ. But I really like having the big screen on the GV1 to set it up.

I just got a TJ for my 50v2. Works as advertised. I got the remote adjustment version and can switch between 2 headspeeds. Installation and setup was quick and straightforward following the instructions. The stock fan has built in recess for the magnet so it's real simple to install. I actually installed the magnet and sensor brace without dropping the engine.

Performance wise, I couldn't be happier. I was so occupied with testing the TJ by throwing multiple flips/rolls to see if I could bog it that I actually ran out of fuel (never happened before).

I would recommend it to anyone. Please note that you will need to optically tach it to confirm the actual headspeed. The calculated atv's will get you in the ballpark but everyone's setup is slightly different.

Both the adjustable (ATV) and single setting TJ are excellent units. No need to use anything else. As previously stated, optical tacho is a good idea for fine tuning.

I have a TJ on my R50v2. So far, it works great. I agree with using the optical tach to dial in the headspeed.

Throttle Jockey

Get the TJ. Use the money you just saved on fuel and go fly. No, really, the TJ is an awesome little device. Folks have compared the TJ and the GV-1 back-to-back in the same heli and the TJ did a better job.

I watched two guys trying to get their GV-1s setup this weekend. I just chuckled and told them they should have bought TJs. The TJ is simpler, smaller, lighter, and it does a better job. What more could you ask for?

What about the helimax?

I fly 3 helimax govs, and at $65( approx) at tower the price is right too. I have them on my ys80 ys91 and OS32 , and all work as advertised.
My head speed hold as good as any GV-1 I've seen.

Alexander,
I apologize if I made it sound as if the there is no place where the GV-1 might do better. In fact, you rightly pointed out that a "flaw" of the GV-1 may actually be of benefit (that being the overshoot acting as a bit of a cyclic booster).

As to setup errors with the TJ, yes, they have occured but it always seems to be the user, not the device itself. It just does what you tell it. I just couldn't get over those two guys spending over thirty minutes going through their GV-1 menu screens trying to get things setup.

I think the hitec 525 is the best choice for the money, very fast and allmost corless like centering.

I overheard a conversation at my field the other day which I found interesting. I was thinking about a TJ for my R50 after I get an 8103 and some 811 servos, so it's not a huge issue for me, especially since I'm still doing loops and curcuits.

Basically, the conversation was about fats throttle servos with a governer...

When using a normal setup it is good to have a faster throttle than collective servo so the engine doesn't fall behind the collective.

What about with a governer? If the governer can only input to the servo at a certain speed, would a fast servo be overkill since the servo would be faster than the governer?

Whats the rating on the GV1 vs the TJ?

Two places (three if you find one in the classifieds)

Heliproz is a tad cheaper.

> can the TJ be tweaked like that?

No, it can not. But it also does not need to be tweaked by the user. It uses an adaptive feed-forward control loop which automatically "tweaks" itself to your flying style and your helicopter. Works like a charm.

From the looks of those "hidden" GV-1 parameters it would appear to be a good 'ol PID control loop.

Throttle Jockey

Hi Everyone,

The throttle jockey has been an improvment for me over the GV-1 governors. I switched 6 GV-1's out for the throttle jockeys about two months ago in raptor 50's and 90's. It holds rotor rpm better then the GV-1, as a practical matter for us sport fliers. That is what a governor is all about. It installs easier in less space. Support for the T.J. is also much better for it from Model Avionics, then the GV-1 from the empire. Ask me how I know.

The unit is rugged, and uses a sensor which won't shatter the plastic case and is easy to install. There is no display, and it does not need it. That is also one less thing to break in a crash. Because the unit is small and light, it does not break as quick in a crash. There is a simple version of the T.J. also which offers one setting for speed with an adjustable pot if you prefer this. It is so simple to install and set up most could install in to flying in less then a half hour start to finish.

I am not a pro concerning radio systems and acc. I use what is simple, works well, and is prudent to buy. This equipment is changing so fast with the tech. out there today, better equipment at resonable prices is now hitting the market every month. The GV-1 is a good governor, and was the first governor system that worked pretty well. It is now becomeing a dinosaur of sorts in tech. Compared to the throttle jockey governor system, it is pretty slow at correcting our engine speed now. The GV-1 can only run the throttle servo at one speed, no matter how fast the throttle servo is.

If you have run a T.J. and still like the Futaba better that is great. If you have a Futaba GV-1, give the throttle jockey governor system a try. Set it up the way the directions tell you. If you have the available engine power in your helicopter, the T.J. govenor system will delight you with it's performance over the GV-1 for solid control of the engine speed. Even through the fastest moves. You won't be fiddling with menus. Just install the T.J. with good end points on the throttle servo, as the directions show you and explain. Run the calibration, and the T.J. will do the rest.

I am pleased with the performance of the T.J. system over the current version of the GV-1 system. You guys try one, and follow the setup directions, you will be surprized at the performance gain it provides controling engine speed over the current production model of the GV-1 system. The T.J. governor is also half the cost of the GV-1 system. Again as a practical matter, the T.J. is at the very least as good as the GV-1 system, and is simpler to install and cheaper to purchase. It holds engine rpm's better if the available engine power is there. No governor will work well without ample engine power output for the job, through hard 3D type flying.

The T.J. price is great, and the product support is excellent from the MFG. It is also much newer tech. and was designed correctly for the job we need it to do with todays high powered stuff. Throttle response and corrections are acomplished very fast and accurately by the T.J. If you are a sport flier, or an all out 3D monster, the throttle jockey will perform engine control perfectly. Nothing is more constant then change, and our electronics are subject to this rule also. Try the throttle jockey if you need a governor. Or if you want another governor for a second helicopter, most of you will be more then happy you tried one.

TJ Fan

Hey guys, great info on both the GV-1 and the Throttle Jockey, I myself am a huge fan of the Throttle Jockey. Here comes a company (Model Avionics) that produces a product that does as well or better what the GV-1's 2+ year old unit does. The Throttle Jockey is simple to use, which adds to it's appeal. For those high-end guys that love to tinker with their 9-zap radios and GV-1 gov. that's great, I just want to fly (or try to stay out of the dirt here lately ). Hat's off to Model Avionics for a great product and support.
