2.4GHz vs 27mhz range
Hi All
Im still fairly new to the R/Cscene Iam wondering if there is a range difference between 27mhz and 2.4ghz.
Wasn't able to come up with a precise answer doing a forum search.
Icurrently have a 1/10th HSPXSTR buggy with 27mhz transmitter. And Iordered a 2.4ghz version of the same vehicle.
Will a 2.4ghz stock system get more range than a 27mhz or vice versa?
Thanks

in comparison my 27 mhz radios went around 200feet away and would start glitching a little, my 2.4ghz system goes past the point I can actually see my RC's and stays in perfect control the whole time

RE: 2.4GHz vs 27mhz range
Thats good to hear.
The 27mhz system initially "stuttered"at about 100-150 feet, but Ibelieve it could have been interference or maybe wasn't poiting the antenna at the vehicle properly.
After a few runs Inoticed the range increased more. Can't wait to try the 2.4ghz brushless
thanks for the replies so far.

Haven't visited Hobby Hobby yet. But http://www.bigboyswithcooltoys.ca/ was ok. Also Galaxy Hobby is not bad but expensive.
For people starting out RCIrecommend http://www.*********outlet.com/ (mostly HSPbrands there but they work)
I'll be doing most of my hobby purchases online as these hobby stores have really heavy premiums.

2.4Ghz range depends on which brand you buy it seems. I use a losi 2.4 GHz system which is the same as spektrum and the range isn't so great. It actually runs out of range while i can still see the rc pretty well.

Ok thats what I've been guessing. The brand name is HSPbut Ihave no idea what kind of electronics are on it. Only know that the motor and esc are Novatech.

RE: 2.4GHz vs 27mhz range
I dont own one but friends say that they go farther, less radio interference from random things, more responsive, and no pain in the ***** crystals you have to change if someone has the same as you(this is a problem for me because i have 3 friends with a slash and we all run together and 1 friend got theirs, i got mine and it had same crystal as his so i had to get a new set, then another friend got one after me and it has the same as my new set so he had to get a new set as well, the 2.4ghz connects to a set reciever as i believe and not have to worry at all about other drivers radio interfering

RE: 2.4GHz vs 27mhz range
2.4 GHz probably is more or less the same range, but there shouldn't be anything in the way with the 2.4 GHz system....it's definately line-of-sight. Drive behind a tree and you might lose contact.
An AM radio can be designed to transmit further, but finding a 4 watt AM RC transmitter isn't too common. Maybe for aircraft radios.
2.4GHz is much less prone to interference. It's frequency is much higher than outside interference, and much higher than any significant RF harmonics generated by metal-to-metal contact.
2.4Ghz also employs frequency hopping that helps eliminate glitching from interference as well as the signals are coded so other similiar transmitters can't control your vehicle.
I'm pretty sure 2.4 GHz works with digital servos while AM may,, but generally only works with analog servos, so you can get better precision with 2.4 GHz.
For a ground vehicle with a vertical antenna, you should hold your transmitter so the antenna is vertical as well. Signal strength is greatly reduced if you point your antenna at the vehicle.

You can run a digital servo on anything you want... the reason for digital is so you can plug it into a tuner and change its throw and curve.

On the other hand, besides your reason for digital servos, there are other benifits such as higher resolution, faster response, and better holding power.

Yes, I was wrong about that. I was thinking about HRS mode benifits with digital servos, but confused myself.....LOL. I think only 2.4 Ghz radios have an HRS option, but I'm not 100% sure.

The system I'm familiar with has both PPM and HRS:

Actually, the advertising in the link tells a lot about the benifits of 2.4GHz....so the OP may want to take a look.
