In those olden days, they didn't even have tail gyros !

Glad I was NOT part of that group of pioneers !!

Been there, done that and old enough to know better.....

It really depends on how far back you want to go, but I know they had gyros In 73, as I bought a Kavan unit, and still have it. There were however, no Heli radios, and it all had to be done mechanically. Sometimes very frustrating indeed. You have no idea how easy it is to get into and fly heli's today.

Nothing happens except the Heli is a little strange in FFF and you will need to experiment with different blade weights to suit to your liking......also nowhere near as fun

Just set the 750 to tail gyro / gov mode only. You don't have to run the gov. But there is an option. To run just the tail and gov with out the fbl.

No where near as stable, no adjustability in seconds, not point and shoot....etc.

What happens if you go FBL with only a tail gyro?
You'll have a) the most fun you've ever had (even in just the hover) with a heli and b) learn a lot about how to control the machine...

heli-cuzz coined the term NOBAR for just standard CCPM mixing on a FBL heli with no stabilization, and that's what you'll have with just the tail gyro.

I flew my 700's NOBAR for several months and it was a total blast. You can spend the entire flight hovering if there's a stiff wind (i.e. 20mph +) and never get bored with NOBAR. Slow piros while NOBAR are the meaning of the word 'excitement' in every sense lol.....

I'm back to the Beast on my machines currently since I'm experimenting with ultra-low headspeeds and need the extra stability, but I still highly recommend a good dose of NOBAR at at least some point in your FBL flying activities.

The main thing about NOBAR is the trim effects of the wind; the pilot has to do the compensating that the FBL unit normally does for him or her.

If you try it, I suggest a lower rotor speed (i.e. 1600 or so) and set of heavy FAI blades. A standard Bell rotor head is off the hook responsive by itself so you want it calmed down a little bit at first while you get used to it. It's like balancing a marble on top of a table for a little while, and then it's a lot of fun.

Also, don't use any expo. You have to hold corrections in when there's a relative wind through the rotor and expo will aggravate how much stick you have to hold, which can be uncomfortable on the thumbs. Low rotor speed and heavy blades will accomplish the initial calming down effect instead.

The hover is very natural without the gyros, even tho you have to hold corrections in. And autos are a lot more like your old flybar in the flare and touchdown....

In FF, it no longer flies like a pattern plane but much more like that old Tower Hobbies .60 trainer you had such a blast with first learning to fly r/c on, with the ballooning and tendency to roll in one direction, etc....

Not for the faint at heart, but absolutely the most fun you'll ever have with a heli ever.... and yes it will make you a better pilot since it really teaches you how to control the machine.

If you want real stability, you need an older X-cell, or a Hirobo Fai Machine. The align heli's where not designed to be a smooth stable flyer. You could maybe change the ratios, but never ever get it as smooth as an X-cell or a Hirobo FAI machine.

The head speed you are wanting to try, is what we all used to use, and not this crazy high stress crap you need for 3-D.

No matter, you still need to fly the heli, I never had one that did not need attention most of the time in a 20mph wind.

Anyway it kind of reminds me of flying Full Size Hughs 500E,Stable, but you need to fly it and pay attention. Rather than move the stick, you think your direction and it goes. Not much stick movement. Climbs like a "homesick angel", and if you get behind the power curve on a decent, your "Dead" as you will become a cement block.

Yep, you gotta fly them darn helicopters all the time, models or fullsize.
