Have any of you guys used the hen long RX-18 control board. If so what type of transmitter is used with it?</p>

The Heng Long Transmitter. I think they have come out with a different 2.4ghz RX-18 to do spectrum radios.

75mhz FM radios are used by the standard HL RX18. easy to get crystals available on e-bay if you need to change the channels.

So I could use any 75mhz FM futaba radio to control the RX18?

No you need to use a Heng long transmitter that is meant for the RX18, the only way to get away from using the HL tx is by getting an add on of some sort to be able to use an aftermarket tx.

FreakyDude, I've read that the typical Heng Long tank over the last few years uses the 27MHz FM frequency chips, while some of the much older ones may have used 40MHz.
I did check both my current HL tanks &amp; the chips do have 27MHz FM printed on them.

01 fm 27 .145
02 fm 27 .195
03 fm 27 . 095
04 fm 27 . 550
05 fm 27 . 245
06 fm 27 . 295
07 fm 27 . 345
08 fm 27 . 600
09 fm 27 . 650
10 fm 27 . 680

Hey John if your wondering about radios Freakydude at http://www.shop.immortalhobbies.com/...1212121203.htm sells an upgrade system

Johnny

By the time you faf about with all the addons you may as well get a Clark board with a cheap hobby king 2.4ghz radio. Or a second hand dx5e

Agreed

I am trying to keep the cost down. I have a bunch of futaba radios and I saw one time that there was a motor controler they could use any TX. My motherboard in the tank seems to be out and I noticed there was a company on the net called RCCOMMAND that sold them but they appear to be out of business....

There is this you could use.

The RX 18 is a good board now. I have used them lots and many people who have DBC3 use them. I wouldn't be so quick to throw it out.

An RX 18 when mated to a DBC3 is a good combo. One of the many things a DBC3 does is add the ability for you to use your Futaba receiver with the RX 18. Again the thing I am pushing is that you can move one DBC3 around a Fleet of RX 18 stock Heng longs, and not have to invest in a new board in every tank. The plug and play DBC 3 requires you to plug in the 3 wire control cable from the RX 18 , and that is it. IF you mount the DBC3 and a Receiver on a small board this unit can be moved around very easily.

A DBC3 cost $9.00 more then that other product and for that 9 dollars you get a fully Tamiya compatible battle system and momentum. So shop around, find out what you need. Lots of options are available,

Cheers

Where can I get the DBC3?

The early (Very Early) no S & S HL tanks were on 27 & 40. They had a switchable A-B-C setting to be synced with the tank. Many worked only on one of the ABC settings. Later when the smoke and sound tanks came out, they went to the crystals HL# 1 to 4 on 27MHz. Six more are available in the aftermarket. FYI, these are not the same as Traxas crystals. Good luck.

The absolute best option is to go with a Clark TK20 board. Very few systems out there can compete from a value point and here is why<div>1. Both 75mhz and 2.4ghz Radio ready ( even am radio compliant) - Futaba compliant as well</div><div>2. Supports both battle systems either HL or Tamiya</div><div>3. Competes with the top of the line sound systems</div><div>4. Does not rely or use the RX18 which has a host of issues all of us tankers have been working to get rid of</div><div>5. BB to IR conversion is too simple if that is the way you want to go</div><div>6. Proportional ie you can move your turret 1/4" accurately and you are no longer stuck cycling through the gun elevation.</div><div>There are more reasons but if the the 6 above don't make you at least investigate a TK20</div><div>then how about the cost at $66.00</div><div></div><div>There is no system out there on the market in the world that is a better value</div><div></div><div>If you want low cost though I can sell an RC2HL radio adapter that will allow you to use your 75mhz Futaba Radio for a low cost of $45.00</div><div>it is just a Radio adapter though and does nothing to help the quirks of the RX18

Oh and Craig is right the RX18 is 27 mhz but the Futaba is 75 which was on my brain when i posted the message earlier</div><div></div><div></div><div></div>

The Clark Board is a great value, and just about what everyone wanted at a cost that is incredible. I would like to hear how it performs on the battlefield to remove all doubt about it.

The ones I have stop the tank in it's tracks when you fire, but that might be just something to do with the set up.

Believe it or not that is my one reservation about this unit. There are so many options in the set up, that every tank can almost have unique settings. I think very quickly, clubs will have to determine how they want these things configured when they show up at battle days. However in keeping with the IRCTO standards, Clark( with help from his friends on the forums) has developed a system that can be dumbed down to play wiith Tamiya, uses the Tamiya apple, and still incorporates all kinds of user definable set points to enhance game play. Kudos to him for doing the impossible, and has produced an incredible piece of tank electonics for a Price I thought was impossible. It makes it hard on resellers because his margins are so low, but he is doing the tank hobbist and incredible service for selling these at $66. His delivery price of $3 alone make it a very hard product to compete against. I can't mail in a parking ticket fine to city hall for that amount

As far as service goes. I had two very early boards that weren't quite ready for prime time. He has offered to exchange both of them for the upgrade ones that will be for sale.

So I agree with Freaky, you have to look at the Clark board very seriously, and as long as it is durable could be your best bet. I am going to hold off calling it your absolute best option, only because we have heard very little from people who have battled with them. I have to return the two I have and get them replaced with the updated versions before I can personally recommend buying them. The two I have only have an IR range of 8 meters which just doesn't cut it. This issue has been resolved though in the TK 20E and TK22. One needs to be aware of this though. Personally I would go with the Tk22 with momentum It is $80, but still a great price. .
