having a crack at fbl

[trexsteve700]

Hi all, just after a bit of advice.
Im finally gonna bite the bullet and have a go with fbl on my 700n, I've
found a head and 3g system on v1 at a good price as i didnt want to spend a fortune
on something im not sure about. So my question is would this system be good enough
for me just to check it out, if i like it i may upgrade when funds allow.i
I know there are better systems out there but i just want to try it first with something basic.
cheers for any and all help.

Someone I fly with uses 3G on his 500 and it suits him fine.

I personally wouldnt make your decision on FBL with the 3G unit, there are others out there a million miles better.

I have seen a few TotalG units go for peanuts, maybe worth keeping your eye out for one. I found mine really good and would definitely recommend one; I only sold mine as it wasnt compatible with my Outrage HV tail servo at the time (may have been updated since).

I think Ian ( coolice ) seems to have plenty of experience with the 3G maybe give him a shout ;-)

I use a 3g system on my 600N with a Spartan gyro for the tail, getting good results with (coolice's) settings.

I'm flying my 700N with the 3G unit and would advise updating the firmware to V2.1 but no higher and I find it works well enough for me.

Thats a good point, i fogot about weather or not to need the gyro too, its an align 780, would it be ok

I put a 3G on my 450 Pro, with Coolice settings and it flies really nice. May not be the best FBL unit out there, but with a bit of effort and fiddling it works just fine.

The tail gyro built into the 3g as I understand it is based on the GP780 and some find it ok, I personally find the GP780 is prone to a wag problem that I could not resolve so fitted the Spartan and the tail is great now.

Just converted my 600LE to fbl using a 3gx flies fine, using Leon Luke's settings, got the bug now

Didn't MadetoFade post a thread recently on a low cost free ZYX that he thought was worth a look - trying to find the thread.....

Hey.

The 3G as has been mentioned is a good little FBL system for not a lot of money now, Duncan Osbourne is still using them in his 700E's

When it comes to the bench setup it's quite straight forward, entering DIR mode and setting up the collective and cyclic pitch ranges, before moving on to teaching the unit it's limits and directions etc. This is all done via the transmitter and is the easy part.

The not so easy part for some was in the actual flight tuning, knowing what each of the PC changable settings do and how they effected the models flight performance and feel. The latter was made easier I feel if the pilot had a good understanding of how to tune a flybarred heli, in this case what all the various ball positions available on the flybar/arms etc. did and what changes they made.

However, I would not be put off and can honestly say I think you'll find the 3G is a nice introduction into FBL flight performance.
As has been mentioned I spent a lot of time tweeking, flying and tweeking some more, until I had a nice flying model. The settings I came up with and used myself, are being flown by many still today (thanks for the kind words on their performance guys) and so you will always have help available should you get stuck. I will more than gladly answer any questions you may come across and offer any help that I can.

The inbuilt gyro I had great success with to, it held nice and did not let go in any manouvers I threw at it.
When the unit was fitted to my 700N I did employ the Spartan mounting system (thick pad/metal plate/thin pad) to mount the 3G sensor onto the model. I used this method on my 700E to with excellent results.

Also, as mentioned in a previous post I'd stick to V2.1 firmware as it was the best flying one. V3 improved the tail performance, but at the expense of cyclic feel.

My only other piece of advice is to do with regulators, what one are you currently using in the model?
The only gripe some had with the 3G was that only one power wire fed the 3 CCPM servos, you can fashion leads to fix this, but I went with an ElyQ regulator. This unit takes the 3G's servo outputs in one side and has the servos connected on the other, passing them positional signals only. The ElyQ deals with all the power supply and amp draw needs of the servos, eliminating any possible power supply problems.

Thanks for the headsup coolice. Your settings are much employed and respected you must av put more time into setups than i have in flying. Do you have any recomendations on which blades suit the 3g. Im no smack pilot just into generally chucking it about and enjoying it at mo.

>> as i didnt want to spend a fortune on something im not sure about


hint: Either do it properly, or stay away from flybarless.
The in-between is full of badly flying helis, crashes and general unhappyness. Avoid it.
There is nothing wrong with a flybar, especially if you get really good at setting it up.

Hey.

You're welcome buddy, glad to help.

I think for myself the main thing was that I didn't give up on the 3G, but stuck with it to extract it's full potential. The larger models (550/700E) didn't take too long to dial in, my 450 PRO on the otherhand was the most time consuming to get just right.
I must say however that it is great to read all of the good feedback from fliers using my settings files and that they recommend them to others to try. While I love the hobby, it gives me great satisfaction to know I am helping others

On the subject of main blades, initially on my 700N I flew the 690D's and they were good with the 3G. Well behaved in flight and didn't make the model feel twitchy or unstable. Later on I switched to the 690 3G's which are definetly better for FBL use.
However if you currently fly with the 690D's then don't rush out for a set of 3G's, try the ones you have first and then in time if you choose to, try a dedicated set of FBL blades.
