Default old equipment

I'm wanting to get back into RC racing and have some questions about the equipment. How much has technology advanced in ESCs and radios? All the equipment I have is from around '93 or so. Would these be at a major disadvantage in todays RC world? What about motors and batteries? I've got a truckload of old equipment and am curious as to how much would still be usable. Thanks in advance.

If you have batteries that have been stored since '93 (11 years ) then I would suggest getting new ones for racing. You will be able to notice a big difference between flat cells and fresh new matches cells! ESC's have come along way too. Radios and motors can go either way I guess. If you can rebuild and tune a motor I think you'll be alright. I think radios are pretty much personal preference since I don't think many people can tell the difference betwenn .09 and .07 seconds. I can't anyways!

Most people will tell you that there is no substitute for practice and teqchnique. So I would start there. And then just replace what you got with something newer and better once you've outgrown your equipment.

If you have some experience under your belt and take time to tune and pracitce, you shouldn't be at a major disadvantage.

But then again, what do I know?

Default Equip from the last millenium

Well spoken, j240z.

Some of my equipment are from the last millenium: KO Presto, HPI Pro2, LRP v7.1. And I do pretty fine at club level.

But for batteries, I'll also tend to say you're better of getting some new ones. This might require a new charger, almost all new cells are 3300 NiMh. Get GP, dont buy Sanyo, too high IR.

What car will you be driving? Either off road or on road have totally changed since then. You might want to upgrade you kit or sell it to me real cheap if it's a Tamiya .

i've got an RC10L pan car and a JR-XXT stadium truck. The speed controllers are Novak and have two futaba radios and one airtronics radio.

huskercheese,

Your 10L will still be competetive (with fresh tires of course!). If you're racing stock then the Losi truck should do fine as well.

The ESC's will do. You'll need new batt's (and a charger that's able to safely charge NiMH if you go that route). If you're running stock it would be well worth the investment to get a modern rebuildable stock motor.

Your only major concearn will be with your transmitters & receivers. If they are on 75MHz they may not be of the current narrow band variety. The "space" between channels on 75 was reduced to allow for extra frequencies. Currently there are even (channel's 62 to 90) and odd (channel's 61-89). If your stuff is old "wide band" format then you will cause interference to adjacent odd frequencies as well as be interfered with by the newer "narrow band" frequencies on the odd numbered channel's. There are some great radios out there right now that are FM computer radios (Futaba, Airtronics & JR) that are attractivly priced and some are also available with synthesized frequency selection (no crystals, just dial in your desired channel).

If your radio equipment is on 27 MHz nothing has changed. Your only concearn would be the large number of RTR's that are around. The vast majority of those come equiped with 27 MHz systems (all Traxxas, Associated, HPI RTR's).

Good luck and welcome back to racin'!!

how would I know about the radio frequencies? I would assume that I have the older frequencies but am not certain.

Look at the crystals. If it's 27.xxx, it's a 27. 75.xxx is 75.

I know that! I was referring to the new "narrow band" frequencies. How do identify if they are in the "narrow band"??

cheese,

Following is a list of 75 MHz frequecies. Just find your frequecy (75.xxx) and if it's an odd # (definite narrow band) then you're golden and ready to go. If it's an even # (could be wide or narrow band) then you'll need to check the transmitter & receiver for a silver sticker stating "narrow band" or something to that affect. If all else fails you can email the serial # to the manufacture and they can tell you.

Ch Freq
61 75.410
62 75.430
63 75.450
64 75.470
65 75.490
66 75.510
67 75.530
68 75.550
69 75.570
70 75.590
71 75.610
72 75.630
73 75.650
74 75.670
75 75.690
76 75.710
77 75.730
78 75.750
79 75.770
80 75.790
81 75.810
82 75.830
83 75.850
84 75.870
85 75.890
86 75.910
87 75.930
88 75.950
89 75.970
90 75.990


Hope this helps!

Ahhh, I see. Sorry. I did also wonder about your question, but now it makes sense.
