| Do I need to replace my Radio system?
Hello, I have an axial wraith and I was told to but an external BEC on there because I am running a Hitec servo with 611 oz. of torque (HS-7985th) anyway my problem lies with when I drive about 30 feet it looses connection and It has been doing this for about a month now, it just stops and starts going forward by itself, know when I say "going forward" it just about 4 inches away from where it stoped, it doesn't brown out or run away from me its not that. Should I put a Spektrum DX3c system or is it something else? I need to know so I can order what I need and not worry about it anymore. The ESC I am running is a Tekin RS with a 13.5t motor and will be change soon to a 10.5t but I have to fix the lose of connection issues before I do so. And there is NO interference, I made sure of that. If anyone can help me I would really appreciate it Thank you. |

How are the TX batteries? One of them could be low. Is the RX antenna away from the ESC, motor & motor wires? It should be. Is the RX antenna wadded up or stretched out? It should be stretched out. |

Hello, thank you for your help. I replaced batteries in my radio system but did not fix the problem. So I just ordered a brand new futaba 3 pm 3 channel with the 3 channel receiver and should be in by the 22, cant wait, yeah 180 on the card! |

So you run a 611 ozin servo with no external BEC?? if yes then I think you will still run into problems even the new radio may solved your range problem. BTW waht is a 7985TH servo? never heard on this one and can't seems to able to search it... Is it a 7980TH? Last edited by Colgout; 05-19-2013 at 07:31 PM. |

Yes I do have an external 10 amp BEC from Castle Creations and my mistake the servo is the HS-7980TH with 611 oz., I was told by a few other techs. that I called and he told me to replace the radio system which I ordered about 2 hours ago (Futaba 3 pm) and anyway, when I get that new radio system all mounted up and made sure the TX have batteries what happens if it still loses connection? Because my tekin RS ESC is working just fine so is the motor and the BEC is working 100%, as well as my hitec, so it couldn't be anything else besides the radio system. And with a 2s lipo. Thank you for replying, I do appreciate it. |

| Re: Do I need to replace my Radio system?
Can I ask why? The futaba is priced liked that on every website that I check, and like I stated earlier I only need a 3 channel, I think futaba's are more reliable than flysky NO OFFENESE that's just I what I buy, I heard that the 3 pm is way better than spectrum and is very good system. Besides I have been spending tons of money on my wraith so far and cant afford to much anymore aalready put $1300 into it, I really don't feel like spending anymore money than I just did on that radio system. And a few techs. that I called told me to put this system in it, and emailed them they also sed the same thing, I just wanted to double check before buying this system, Is the futaba better quality than flysky? |

What losikid is saying for that amount of money you may aswell get something much better and more worth while. Does the 3 pm have a 3 pos switch? If it doesn't...well thats wayyyy too much, and if it does it's still too much. Losikid stocks hacked flyskys that do everything you could ever want and more for just over $100 with heaps of options. You can have 6ch's easy and can have proprtional mixing, 4ws, run multiple acessories no problem. With very good quality. Futaba has good quality it's just the price and what your getting. Go with flysky hacked and you'll never regret it. Just my 0.02.

| Re: Do I need to replace my Radio system?
If you want a futaba, thats fine its a great radio. BUT i recommend 100% against a futaba 3pm for $180. The Futaba 4pl is 1000x better and only costs a hair more for a new one or buy a used one for less than $180...also, the 3pm is not way better than a spektrum, i'd rather have a spektrum dx3r than a 3pm. I think most people will agree, i'm kinda a radio guru....and i'm confident you will regret buying that 3pm. |

I don't have one, but i'd almost bet that someone has a old 3pm laying around they'd sale for less than 50 bucks (I'd probably give it away)....they are kinda worthless, the 3pmx is alittle better but the 4pl is still a much better radio than that 3pm

The 3pmx does have alot more options switch wise (its has 3 position and a step rate type switch)...which makes it alot more capable but still far from a $180 radio. | |

| Re: Do I need to replace my Radio system?
Ok, can you tell me why though? I look up used ones for up to 340 bucks around their so don't hold me to it. But for that money I can buy 3 lipos and other parts, I don't need more than a 3 channel radio , and yes I think they are worth it, because it works great, I just had to adjust my trims that's all. So the 4pl is way to much money, I cant even fork out an extra dime on this wraith. and besides, the 3pm-x was recommended by a few techs I called and few other guys that race, I don't need anything to fancy, I now that you are trying to help, its just that the 3 pm-x is a great radio system for me, and Its all ready to go in the wraith all mounted up, wires organized, and ready to bash! But thanks for your help, I do appreciate it .

| Re: Do I need to replace my Radio system?
I run several radios from Dx3e, Dx3s, 2PL, 4PL, and a handful of cheapy RTR 2.4Ghz Team Associated radios in case I ever want to sell the entire r/c as ARTR just add batteries. I even run a 12+ year old Tamiya FM 2 channel radio in my TT-01E simply because it's just a fast basher car with minor aluminum upgrades such as aluminum center drive shaft, Sidewinder SV2/6900kv and some old HPI Sprint aluminum oil filled shocks to replace the stock plastic ones. If you don't care too much about digital response speed from TX to RX which in turn would affect your lap times in racing on/off road you really don't need anything more than a Dx3e for crawling unless you want to get into mixing for dual MOA rigs. Really the benefit of the 4PL is targeted as an awesome sport radio for racers and crawlers alike. Digital mixing, easy setups, awesome adjustments, easy EPA's since it's all digital, fail safes, etc....list goes on and on. But for surface radios I will always choose Futaba hands down. I've had too many issues with my Dx3e and my Dx3s 20% of the time bugs out...either won't link with the receiver or I have to recalibrate the TX to the ESC again. Something about Spektrum....oh well. Maybe their new Dx4e is a significant improvement... |

I run a 3PM-x in my 2.2 Bully and like it. I ran a servo dig in it at first, then a WantAmix with dual ESC's. My only real issue with the 3PM-x is that additional RX's are almost the cost of a hacked GT3B. | |

| Re: Do I need to replace my Radio system? Simple, you'll regret it when you get a dual esc moa or want to add accessories to a scalar thats controlled by your controller. Quote:
I also see them in the rcc classifieds every now and then for less than $200 and i've seen sells where they are $215 .... I keep up with the prices to make sure my flyskys are still more affordable Quote:
I'm not saying its a bad radio, but a futaba 3pm (as you orginally said) isn't worth anywhere close to 180...even a 3pmx isn't worth that unless you're racing and need the FASST. The 3pmx is the budget racing radio and the 4pl is the budget crawling radio. The 4pks is the do it all radio. See above....you are misinformed. Then why buy such an expensive radio? Quote:
I'm trying to save you $180 ... believe me, i'm a radio guru and i get emails all the time about people switching from their radios to my flysky's. Only radios, crawler wise, i can't/won't argue about you getting for crawler stuff is my flyskys, the futaba 4pl, or a futaba 4pks. If you're on a budget or need the extra channels, get one of my flysky's. The 4pl is a budget higher quality radio, and the 4pks is the expensive 4 channel do it all radio (my flysky's still has more channels though , so it can do more in depending on the application) Quote:
