I had module failure in a high zoot Hitec radio and never went back to them. At the nats no less. SO pissed at the time. Ended up running Ray Fullers Airtronic radio. End points all screwy. ugh
I suppose it's true of any system. Once you get burned you never trust them again.Noisy personComment

and the GT3C uses only 1 lipo battery for power.
Finally a company that figured out that the present day electronics do NOT need 12 fracken
Volts DC to power the units.................Last edited by carlcisneros; 11-03-2011, 12:13 AM.Comment

My FS GT3B experience
I am not choosing sides here, But this is what recently happen to me. The other day I took my Aquacraft UL-1 hydro to my local boat hole before the Broncos / Colorado game to run. I am running a pro boat esc and motor on 4s. I hand launched her and she jumped up on plane and started flyin. After a few loops at half throttle, I pinned the throttle and cut her loose. She got about 100 ft from the bank and went dead in the water, total signal loss. 
I spent the afternoon lakeside watching my boat float around on the currents. i also missed the ball game too
. a friend showed up after the game with a rescue boat. he paddled out and grabbed her for me. I held the throttle on the way back in & about 85' out, the motor took off again.
The GT3B is a great radio for the price, but its only good for my cars and trucks. because it sucks on the water. I get too much interference off the water and it disperses the signal. I recently bought a proboat rescue duck and a spekky dsm controller. I will be using the spekky marine rx's. I dont know what contributed to the cause, but I wont chance it again.

The Broncos/Colorado game? Don't the Broncos play out of Denver Colorado? Where they playing themselves? I am not choosing sides here, But this is what recently happen to me.

Leave it to me to notice that trivial detail...
On second thought, if you missed the Broncos getting blown out by the Lions, maybe you probably owe the radio a thank you.Last edited by Stinger9D9; 11-02-2011, 11:42 PM.Comment

Yes, I read your earlier post today - it's what started this last 'debate'. You say you used this radio on the water - and the boat quit at 100 ft. And you're getting "too much interference off the water and it disburses the signal". How did you come to that conclusion? (it sounds like low battery level to me). Have you used the boat since with another radio? Other members use the GT3B (on the water) to distances as far as they can see without problems. Do you suppose you just got a bad one (since they're not all like that), or you might have another problem (not related to the radio)? Sure sounds like you're 'choosing sides' (no offense). And your buddy recovers the boat and you hold the throttle in as he brings it back? I think I'm beginning to understand.

we use our GT3B radios here in Dist. 12 (IMPBA) for racing purposes.
One of the guys in my club here uses his in his twin CMB 80 powered Andy Brown Eagle 2 rigger and also his 45 AB rigger as well.
I use mine in just about all of my racing boats (both nitro and FE).
there are a few other guys that have them and are racing with them as well.
NO ONE has had a problem with them at all.
That says alot for those radios if you ask me,,,,,,,,,,,,,,,,,,,,,,,,,,,,Comment

oops
Sorry about the overpost everyone. I knew I posted earlier today, but when I looked I couldn't find it. So I reposted it with a lil more detail. Yes my receiver batteries were fully charged. My buddies pro boat apache has a farther range than my gtb3 does, and hes using a junk tq2 radio temporarily.
I got the other info from a spektrum tekkie. He said that was why spekky didn't recommend using their products on boats, and why they developed the marine rx's. If I use my gt3b on one of my trucks, I can drive it outta sight and still have control of it. I don't know exactly why it has range issues on the water, but it sucks and I spent a couple hundred to remedy the solution. I would of rather purchased one of the mono kits from Chris here at OSE though.

If you watch this video, this is way beyond 100ft, more like 50 to 75 yards and no issue's. New tx batteries rechargable nimh's at that. Had my gt3b since day one and use it on 3 boats. 2 FC Daytona's and 1 Traxxas Spartan. Radio $37.00. Additional rx's, $6.50. Budget cost's, priceless!

Sometimes I wonder whether the world is being run by smart people who are putting us on or by imbeciles who really mean it.

He was holding the throttle wide open to see if it would run when coming into range (never a good habit). He said his receiver batteries were charged - maybe his Tx batteries were low. I suspected that he either read or heard that statement about "too much interference off the water and it disburses the signal" because that was an early suspicion about 'water spray' interference that was debunked (2.4ghz is absorbed by water spray).
