Model Forum / Radio Controlled / Land Models / February 2006Question about transmitters...
I've got a fairly large RTR that was a gift about 10 years ago called a Supermegatron. It is an electric buggy type, about 20" long, 4x4 with two motors one for front and one for back and runs off a standard 7.2v pack. This thing has really taken a beating over the years and has never had a problem. I recently purchased a new charger and batteries and dug it out of the basement for my 8year old. Problem is it does not have a very good range, only about 50'. I took it apart, and the receiver seems to be built into the internal control board which is sealed inside the plastic chassis, and I don't think it can be replaced. So my question is...will I benefit from purchasing a new and better transmitter even though I won't be able to replace the receiver in the car (27mhz)? I have been considering buying a whole new vehicle (electric not nitro) but just have not been that impressed with what I've seen. I could be wrong, but I have this feeling that what I get will not be much if any better than what I already have. Any help or suggestions would be much appreciated.

Thanks! 1 in 4 chance it's the tx that's bad. You could snag a 27Mhz tx on e-bay for next to nothing so worst case you'd be out a few bucks. It could also be the crystals, or it could be the rx, or it could be interference on the channel you're running on. The only way to tell is to start replacing stuff with known good components until you've ruled everything out. I had an AM 75Mhz system not too long ago with the same problem, about 50' range in all of the areas I run in, covering maybe 25 square miles around where I live. Took it out to the track an hour away and range was infinite. To this day I have no idea why it acted funny in my locale and fine everywhere else. If it were me I'd buy something new for you and the lad. R/C has come a LONG way in 10 years, especially in the electric category.

This is the first time I've been accused of being a troll...curious what about my post makes me a troll. I am definately not an "expert" RC modeler. Something I've been into since I was a kid, but have never done anything more than toyed around in the back yard. Like I said...I got this particular car as a gift from my wife, and the RTR package was in the area of $250. I know that is nothing compared to what you can spend on a decent car with upgrades, especially if it is nitro. I was just hoping to salvage this thing because it still runs like a champ. The only dual engine electric I've seen is the E-Maxx (and some other one that comes with numerous accesories that I already have from Hotbodies). I'm sure the E-Maxx is well worth the money, but then I already have a dual engine electric that may be old but runs good - just with no range. It was a pretty simple question that I felt someone with more experience could answer. Will upgrading my transmitter without replacing the receiver in the car help me? Guess I will follow the first advise I got and see what I can get on Ebay. > > > I have been considering buying a whole new vehicle (electric not nitro) > > > but just have not been that impressed with what I've seen.

Dude...why do you only answer my questions with more questions...which are completely unrelated to my original question. I'll answer it (something you have yet to do with my question in your two posts)...because you are an a.s. You are the troll. Of course I've already searched the internet for more info on the vehicle. I will not repeat myself...my fear is that I will spend a couple of hundred on new vehicle that may not even be on par with what I already have. After all that I have read the last few weeks, I think I may decide to go the route of a nitro monster truck. Need to think on it a little more, and do some more research on my own as far as the transmitter goes. You are a dickhead and have been of no help whatsoever. My first post on this site has not been a good one...thanks for nothing. > > I did a 2 minute google and couldn't find the vehicle you mentioned. > > [quoted text clipped - 16 lines] > whatsoever.

Second best thing in this scenario is for one of use to see schmematic or photos of the working parts of your truck. that's why I asked. Great. I spend a little time thinking I might be helpful and you throw sh.t at me. good luck with the probs on your broken toy truck > "dude", you asked if we could help.

In a perfect world, I would have the schematic and would not need your help would I? OK...Here is your chance if you still want to help. Age old question. First nitro...Savage (I do have some tall grass and obsticles in my yard) or Hellfire - just plain sweet and fast as hell (thus the name). Most important is toughness and reliability, followed closely by go anywhere durability and speed. > > "dude", you asked if we could help.

If you are going to race you could get either. Hellfire is in truggy class at our track Savage is in monster truck class. For pure bashing and wanting a truck that takes alot of punishment and is real fun...Savage. Being that the Hellfire is new there's a lot less upgrades and less community knowledge about the truck. Here's a 14MB .WMV file with a hellfire on a track: http://www.robertlundquist.com/supercrossrc.htm >> I did a 2 minute google and couldn't find the vehicle you mentioned. >> [quoted text clipped - 16 lines] > whatsoever.

You got the answer you were looking for as the first response to this post (by yours truly). The answer is "maybe." Let's not get into a pissing match about it. I can personally guarantee you that any electric you buy today that is hobby grade will smack the poop out of what you have right now. As for your other question, first let me offer some congrats on two excellent choices. Are you going to bash or race with said vehicle? Hellfire will do both pretty well. Savage needs extensive modification IMO to be track worthy as it is a true monster truck right down to the handling characteristics (not good w/o modification). I bash with a MT (Savage) and Truggy (Sportwerks Mayhem ST) and both are right at home in tall grass, gravel, dirt, mud, you name it. Savage can plow right over stuff I have to drive around in my Mayhem. There are trade offs either way. Doc >>>I have been considering buying a whole new vehicle (electric not nitro) >>>but just have not been that impressed with what I've seen. [quoted text clipped - 24 lines] > Guess I will follow the first advise I got and see what I can get on > Ebay. I am curious to see this RC of yours. Inside and out if that is possible. If you can, just send the pictures to me and I can post them on my site for all to see. The advice given in SOME of the other posts about getting a transmitter on ebay is sound but I would go for a full radio set(Used of course). This way you can replace everything if you are so inclined. It is possible to remove the old system completely and replace it, buuuuuuut (and you knew that was coming) it may take some hacking to get it in there. I have done my share of hacking GOOD radios into RC's that were not ment to accept them but in most cases it takes a bit of imagination and some good tools. If you decide to switch the radio completely there are 2 issues you will encounter. 1) you will need to find a way to install the servo that came with the Radio. usually you can fit it where the old one is with a bit of cutting and getting yourself some servo mounts for it as well(if needed or you can make them) 2) You will either need to get a Mechanical speed control unit(not recommended) or an Electronic Speed Control unit. This is up to you but the Mechanical one will also need to be attached to a servo. MacPhreak Thanks very much to all took the time to think about my issue. Based on what I have heard, I doubt it is worth going to the trouble of replacing the radio. I know none of you have seen the insided of this thing, but I have...and it was clearly meant to be an off the shelf unit. The crystals are swappable, and SOME of the mechanical parts, but what you are proposing sounds a little over the top for the design of the vehicle. I still intend to keep it (at least it works for short range play) probably just as a beater - first RC for my kid. Maybe not on par with the new stuff, but a heck of a lot nicer than what I had at his age. Probably after I get a feel for nitro, it will be retired (or ebay'd). I am actually on my way out - got a long work day ahead of me, but if I find the time later this week, I'll take some pictures and email them to ya. And by the way Doc...everything I've read about the speed and durability of the truggy's makes me lean in that direction. However, most of the use will just be back yard stuff, and I live on a mountain (in PA) more of just a big hill really. But there are lots of rocks (some pretty big) and other obstacles that I'm sure the MT would bounce right over. Wish the wife would let be get one of each - but not gonna happen. Thanks again. > Thanks very much to all took the time to think about my issue.

The largest "weakness" with the truggies IME for bashing is their limited ground clearance. You can crank up the shock pre-load to get the ride height to that of a MT, but it throws the driveline and suspension geometry way off (not good!). The only way to really raise the ride height of a truggy w/o messing up the driveline and steering geometry would be a set of 40 series tires that would allow the geometry to stay the same while raising the truck and inch or so at the same time. My truggy is superior to my MT in every way (speed, durability, handling, jumping, maintenance) except ground clearance which makes some obstacles not drive-overable. Doc |
