Wanted
Want to get into fpv, is 2.4ghz the right tx for me ?
I have now ordered a dji naza f450, and almost about to buy a spectrum Dx8, my question is, is this the right choice of frequency for me, the quad will travel max of 50mph say max I get 15 mins flight, that will give me a max distance coverage of 6.25 miles then the same back, so I guess I'm looking at something that will range 10 miles will a 2.4ghz spectrum be capable of this?
What extra things will I need to buy? Will 5.8ghz fpv gear also travel this far? What are my options ? I'm looking to travel as far as I can without a huge setup something I could carry in say a rucksack. As I said I'm new to this and the ten miles I know is a lot but want to have enough because I know I will lose a lot of signal through noise and other interference Any help would be greatly appreciated Thank you |

No 2.4 radio will not travel that far. You must use 433mhz for radio and probably 1.3 or 2.4 for video.

How far could I go with a 2.4 ? With the booster ect they have, the 433 MHz gets interference won't it ? I fly near alot of houses and didnt want to get shot down,
How far would a 2.4ghz tx and 5.8 ghz fpv gear go How far would 433 MHz tx Nd 2.4 ghz fpv go standard Thanks for the quick reply |

I use both 433 mhz LRS (ez uhf) and 2.4 ghz control for my FPV and for quads, I feel that 2.4 ghz is TOTALLY adequate as long as you are using the right system (and Spektrum is not it....). A reliable 2.4 system with genuine diversity such as FRsky will get you out a couple KM and that can be safely extended to several miles with an inexpensive 1wt booster. Many folks in to FPV use this system with great success, and you hear it called "the poor man's LRS" because it's so much cheaper then going with one of the standard LRS systems like dragon link or ez uhf. With a quad you are VERY limited by your battery capacity and I would wager that 99% of all quad based FPV is done within a mile or so from the base station. For this reason, I think a system such as Frsky works just great, and is an inexpensive alternative for guys trying out FPV for the first time. Most everyone (including me) will tell you to steer clear of Spektrum stuff for FPV though, as range is very poor and unreliable even with a booster. FRsky systens plug into Futaba orJR radios equipted with a module in the back, or you can buy the system also that you put inside your existing radio (any brand). All the modules, receivers, etc can (each) be purchased for around $20 and a booster will run you around $50 if you shop around. As a plus, FRsky has the option for inexpensive telemetry, and has real failsafe on ALL channels which you will learn is a really important feature for FPV. Here's a link to a US distributor of their equipment...

Ok thank you for that info, the only reason I mentioned the spectrum is that one is going cheap and I am on a budget is it possible to get the power booster for the spectrum ? If it is I may just stick with that as say limit to 3 km or so is that possible to do then if I enjoy it as much as I think I will I could then invest in some decent gear and get a plane ect

If you are on a budget, then I'd still steer-clear of Spektrum and lean towards the Turnigy 9X.
It has the JR module and is another favorite among the FPV crowd. They sell for $50 (much cheaper then a 6i or dx7). Spektrum with a booster will get you your 3km. but you will have a sketchy link and only a questionable throttle failsafe. I was just pointing you to options that are the same price or cheaper, but that will be safe, reliable, and will grow with you. Sorry, but it just sucks to see someone new spend a tidy sum on outfitting a nice FPV plane/quad only to see it crash or fly away because of an inadequate control link. Take it for what it is..(free advice) and have fun which ever route you go!! |

I'm on here asking questions because I need the help as I don't know what is best, I'm aware you guys know a lot better than me which is why I'm asking, don't be sorry, I'm grateful that I got those reply as you said the last thing I want to do is sulk for days because I crashed my model from ignorance,
So if I go turnigy or flysky think they are the same right ? And I buy the module thing Is it easy to fit ? Will I have failsafe on all channels ? Will I have enough switches for gps hold IOC atti mAnual ect? What fpv would I need? Ghz any booster ect? What range would I have ? Also if I go for the433 MHz Will I get a lot of interference in rural areas? Is that system hard to set up ? What will my range be ? Will I have enough switches to do as above gps ect? I do appreciate everyone's advise so don't hold back tell me as it is, thanks for your help Harry |

A Turnigy 9x with a FRsky module will be all you need to start and you will have almost a mile of range, failsafes on each channel and plenty of switches for your quad with Naza. No need for 433mhz at your point. Just keep it simple and enjoy learning FPV. Take your time and spend any extra time reading and watching the videos on this thread. All the contributors on it are all eager to help you with all your questions too since that's what IBCrazy started it for.
https://www.rcgroups.com/forums/show....php?t=1355327 If I can give you two pieces of advice for starters, it would be to read, read, read, then read a little more. You can ask, ask, ask, but people on here will begin to get frustrated with you if just ask the questions without first putting in some research and effort here on the forum. I promise you, it's all here and easy to find. For instance, there are probably a hundred individual answers to each of your questions above, that can all be found just on the link I've just provided you. Second piece of advice, is to just keep it simple. your quad,a reliable radio/link, a simple 5.8 ghz transmitter, camera, receiver, and goggles or an LCD are all you need to start enjoying and learning the sport. suggestions on actual brands and specific components are all listed on the provided link. Best of luck and have a blast!!!!! FPV can be the most fun you will ever have with RC, but it can also turn out to be a really expensive and frustrating waist of time if you don't take the time to thoroughly research and learn what you're doing... Cheers, Mel |

2.4GHz is a lonely frequency to use for video. I have 8 friends using 2.4GHz for controls. No one would be able to fly Fpv using a 2.4GHz vtx as they would never get any video signal due to inference. So one would have to fly alone and hope no one fires up a spektrum or 2.4GHz. If you don't fly with anyone our have no plans to fly with anyone, go with it.
Frsky IS a great way to start. Way better than spektrum, but then again, everything is better than spektrum when it comes to Fpv. I fly dragonlink 433 and 1.2...never had a problem. Also haven't reached a limit on range yet although I'm sure I'll get at least 5-10 miles without worry. 5.8GHz just doesn't penetrate well.its like Los to say the least. Although I have gone 2k with a helical and spw on diversity. 5.8GHz is the simpler set up. Smaller antennas. 2.4GHz, 1.2/1.3GHz, 900mhz need tweaking, filters, shielded wires, and certain do's and dont's about spacing the components. It Can be overwhelming if your just starting. Best advice:One word: ibcrazy...there's about 1-2 hrs of video with this Guy explaining everything you need to know about Fpv. Google him. Put his name on rcgroups search engine. YouTube him. Good luck |

I also have a turnigy 9x/fs-9x that has grown with me. I put in a frsky module. Never needed a booster as I got a little over a mile with it. Made the very easy transition into the dragon link. Same TX. Modded a xbox controller for pan and tilt, again, same TX. Now my TX looks so space age, non flyers stare at it more than they do my plane...lol the 9x is a perfect TX from entry to intermediate, even advanced pilots.

Ok thanks for that info but I think I may have been misunderstood
I'm sticking with the turnigy 2.4ggz tx as that is what I have been led towards by everyone's help on fpv, All I now need is the correct link to purchase a frsky module, and say a 500mw booster, I will worry about the fpv gear once I have set up trimmed and become used to the quad and its characteristics, though I will be 5.8 ghz on the vtx that should give me a good few miles if done right I just don't want to order stuff that is wrong and waste money Thanks again for all the help |

Why bother will all the booster and stuff?
Until you have built and flown the model 100m away, why buy anything extra for 1km? Best thing is to keep it simple, and buy the minimum you need to get started. Over time and with practice you will know what you need to accomplish more goals. And you WILL probably crash, so get extra parts like arms for the DJI F450, extra props, etc. Everyone crashes, especially learning so save your money for repairs until you are good enough to move on. I would get the Turnigy Tx, the FRsky module, the FRsky Rx, and a Immersion RC 5.8 ghz video system. That will get you lots of fun and experience. |
