700N DFC - Nitro noob - what do I need?

[Delarado]

So, I used to have a nitro RC car but never a heli.

Im looking into getting the new 700N DFC and just wanted to know what I'd need... So a few questions:

- What else do I need except the kit? It looks like it comes with 4 servos. Dont I need one for throttle? If so, what sort of servo am I looking at?
- I play to run it with a Vbar blueline/silverline. Potentially on HV too. Any problems with this?
- What starters are good? I dont mind spending good money but dont want to pay for a name over functionality.
- What else will I need? I guess fuel and a pump too. Can anyone link it?

- What engines are available to me? so far it seems I can get a 90, 105 or 120 size engine? not sure what this means but i'm guessing 120s are the most powerful.
- Whats the different like in fuel consumption? are the 120s really prohibitively thirsty?
- What flight times can I expect with each kind of engine?
- Is there much of a difference power wise?
- Is it worth going 710 blades rather than 690?

- Is there anything else I should seriously consider getting, as far as glow starters etc etc?

[Delarado]

Also, is the bundled governor any good? and what does the 2 in 1 do? It says its a voltage regulator, cant you just run a direct 2s lipo?

[Delarado]

scratch that last question, I now see the servos that are bundled arent the HV ones. Anyone know why this is?

[Delarado]

Also, why does it include a GP750 head lock gyro when it has a 3gx in it?

Ill stop replying to my own threads now! Thanks

Morning Mate.

Woohoo, a nitro............. a real mans model lol

Yeah you're right, this oen on Midlands ; Align T-Rex 700N DFC Super Combo | Midland Helicopters Ltd is the non HV version. One would imagine like the 700E DFC there will be an option for HV or non HV shortly, but I cannot say for sure.
Seems there is a typo wity the gyro as you've spotted, as the FBL unit negates the need for one.

Yes, you will need a throttle servo. Another Align DS610/620/615/625 will work well and not break the bank and I am sure could be included in a deal with any model shop you spend your money in.

With the Vbar you can wire a straight 2s LiPo to it for the HV setup, as you know from our meeting I am a fan of regulated power power supplies on my 700 class models, but the Vbar can certainly take 2s direct ok.

The Align starter is very nice, small for factor and good looking. However some have voiced that it's marginal with the larger 100/120 engines, even on a 90's first start it could struggle but eventually did it. The best one is a Sullivan Dynatron on 3~5s Lipo, much heavier and bulkier than the Align but could start your car

Yep, a good fuel pump will be needed. There are loads and some last longer than others, but I cannot remember the good ones at present to tell you

On engines and going by what I've read I would go the OS105, I used to use YS for my F3C models and they were great. However I have read of some problems with the YS lately, nothing major but I know you want to just go fly so maybe the OS is best for you?

As to fuel consumption, the problem with 90's was their need for a lot of nitro this in turn meant you had to run much richer on the needles which in turn flows more fuel and less flight times. The larger engines seem to run well on 15% nitro fuels, so don't need to be so rich, still produce a bit mroe power than the equivelant 90 at this nitro content and fly for the same amount of time, if not slightly more.
Only the hard core 3D'ers would perhaps feel the benefit from 30% in these engines.

With the OS on 15% fuel, going by what I've seen 8~9+ minutes depending on flight style and throttle used.

YS's have always been more torquey and so can run more pitch as a result, OS on the otherhand more BHP. We're not talking mega differences, but there are maybe benefits to both depending on flyign style.

710's will give more auto hang time, will track and fly smoother for sport flying to perhaps. 690's will feel more chuckable by comparison, but both will do the book.

The Align 2in1, while a very good unit and helpful with glow start I'd say is marginal on amp delivery for 700's, especially on FBL and when using 2.4ghz which is not tolerant to power drops like the old 35mhz stuff. So I would also budget on anotehr regulator or not is going straight 2s on a HV model.

Yes, you can. I'd loose the 2in1 on 700 class model.

Some prefer the non-HV servos I think, also the supplied regulator will not allow full use of the HV's you see as it can only output 6 volts. I just remembered this bit.

I wouldn't power the 610's from direst 2S Ian, some do and have no issues but I'd rather stick to what they're specced at.

Well spotted mate, no I wouldn't advise it either on the non-HV servos. As you say some do, but many have failed quickly when doing so to :-/

[Delarado]

yeah I assumed they were HV servos because the normal 700 DFC is. I might wait a bit and see if they bring out a HV Version of this. Has anyone heard any rumors?

Also, I see there are two versions of the OS105; The HZ and the HZ-R. What are the differences? Power? It looks to me as if the HZ-R has a pump but the HZ does not - but I don't really know what I'm on about Also, Theres a huge venturi thing on it. Dont these engines run air filters?

Last but not least, is the align govenor any good? Can I use the Vbar governor, do I need anything else to run it and is it better than the align one?
