Jim, I'm not sure when it was that you tried the Spirit but the software has got much easier to understand and use compared to the early versions. To be honest with most of these FBL controllers it's mostly about familiarity. I can set a Vbar up in my sleep but that's mainly because I've done...

These were the two helis i had out this weekend, it's not hard to see where the DNA for the Devil 420 originates from!

Dennis, The developer said two to three months and that was at least a month ago.... So if it goes to plan it should be withing the next couple of months. As i'm sure you know, sometimes these technological products can run late so dont set your heart on it just yet. He did say that the...

The accelerometers in the 6 axis sensor detect the direction of gravity during initialisation. From that they know which direction is up and which is down. It's the same technology that allows the display on your smart -phone to flip around when you hold the phone sideways i.e. your phone is...

Each to their own but I've given up using an Rx battery on any of my helis. I now use HV BECs (or ESCs with BECs) on them all and they all draw power from the main flight pack, it's lighter takes up less space and is hassle free, this includes seven 700 and 600 size helis so i can say for sure...

I've not used one but I always considered the Skookum 720 'Black' to be the 'Rolls Royce' of FBL. The Skookum has full GPS compatibility and it uses top spec 'Pinpoint' 3 axis gyros which are more vibration resistant than the mobile phone type gyros uses in most other FBL controllers. The only...

Uri, you probably know this already but for anyone reading who doesnt.... Bear in mind that sensored motors are for RC cars, not planes and helis. The advantage of a sensored motor is that it can produce full torque right from stationary because the sensors tell the ESC exactly where the rotor...

The mini Comet and Fireball do look interesting, the direct drive motor especially. The one thing that puts me off (if i was in the market for that size heli) is the weight... The data published says about 900g which is extremely heavy for a heli of that size.

Yes, that's right. The current speed model will be discontinued to make way for the Comet. The Comet is a complete new design from the ground up, it's got nothing in common with previous Goblins. Some dealers here in the UK already have the Comet available for pre-order but there is no delivery...

Thanks Uri, it's just curiosity to be honest I don't think I'll be getting one anytime soon.

PS... I heard something about the 770 being phased out too, but if that will only be replaced by a 'BlackThunder 770' or some very similar size heli that shares 95% of parts only time will tell. Did your field ref mention anything about the new Goblin Comet 700 size speed heli?... SAB have had...

I just had a go at working out a rule of thumb, what I came up with is 3 watt-Hours of battery energy per Kg of weight per minute of flight. So flight time = Watt-Hours/(3 x weight) Battery energy = 3.7Ah x 22.2V x 2 = 164.3Wh Weight (Kg) = 12lb/2.2 = 5.5Kg Flight time = 164.3/(3 x 5.5) = 10...

SAB do seem to 'refresh' their heli lineup quite regularly. Often the changes are largely cosmetic, like the phasing out of the 630 and introduction of the 'Black Thunder 650'... In reality they are the same helicopter with a few largely cosmetic changes. You could always fit up to 660mm blades...

Uri, I didn't know that the 570 was being phased out, that's interesting. I wouldn't be surprised if they replace it with a heli that's basically the same. SAB did this with the 630, it was discontinued and replaced by the 'BlackThunder 650', but they are basically the same heli, all components...

I think Tony's video is the Align 3GX, not the Demon 3SX (VERY different units). I'll go with Holtneil's recommendation for the Spirit Pro, what sets it aside more than anything is the rate that the developers at Spirit are adding new features.

Dennis, the purpose of the arms is really quite simple. All the arm(s) do is drive the inner part of the swash round so that the inner part of the swash rotates along with the head. The outer part of the swash of course is fixed in position to the fuselage, usually using an anti rotation guide...

It;s the radius arm/ follower arm . It's there to drive the swash round. DFC heads dont need them as they have rigid pitch links, but conventional heads have to have them to turn the swash.. Read this: DFC Rotor Heads Demystified

Welcome to the forum imakethecalls. A sim is a good learning tool for sure. Personally i find them a bit boring so cant use one for more than a few minutes but I'm sure that if i could condition myself to use the sim more often i'd be a better pilot. So what helis are you flying?... Got any photos?

The AR7200BX doesnt have 'stability' or 'rescue' functionality which is a serious omission for a beginner.

Only thing I'd add is that anything much above 30C is basically 'made up', almost all battery manufacturers exaggerate C ratings. You are still ok with the setup you have but if you ever did max out all the motors at once you would be working the battery VERY hard. Chances are that you wont ever...
