Hello to all.

Only just joined model boats a week ago , really enjoying looking around.I need some advice on the workings of wiring in the reciever set up in my radio gear. You see I built a balsa boat kit some 30 years ago. I bought a r/c set up about the same time.

About  1982 I bought new Ni-Cd’s and had the radio certified. I dont remember the last time I used the radio or the boat, was always going to get rid of them both.  The other day I draged the boat and radio gear out of the shed and guess what the Ni-Cd’s had exploded in both the reciever and the transmiter.

 Now the problem is there are 3 wires going to the Ni-Cd pack for the reciever pack a RED a GREEN and a YELLOW .The acid from the batteries had removed all traces of where they went in the battery pack. The reciever pack has only 4 Ni-Cd baterys in it while the transmiter had 8 I’d like put some cheap AA baterys in just to test every thing and hopefully get sailing again. I hope to get some pics of the wiring as soon as I get organised. 

G’day  Chas  Thanks for the reply.

Firstly the servos have 3 wires to them, there is a outlet from the receiver marked battery then to a switch then 2 banks of wires from that 1 to the charger plug the other to the battery pack and this is the 3  wires with no home. Nearly all the wires are red green and yellow. There are 7 more out lets from the receiver pack 1 = elevator, 2 = motor,  3 = rudder,  4 = aileron, 5  = aux 1, 6 =aux 2, 7 = aux 3,  and the first one marked battery .

The radio is an Australian made P S A  narrow band FM 9000 @ 36.45 MHZ   it  was supposedly running a helicopter before i bought it but that may have been a sales pitch.

As for the boat I have no idea what kit it was, it has a small cabin, and a deck at the back like an observation platform, It has pressing marks of doors and windows at the rear as well but i used to rather fancy it as a trawler though it never had nets or booms and rigging it must of been some sort of ferry maybe .I have not got the box or the plans any more. I will send in some photos of it and the wiring as soon as i can shrink my photos down , they are coming out of the camera at 2.3 mg and if i save for the web i cant get them under 950 kb. Hopefully my son can help me with this problem when he is home ( he works away only home between jobs at the mines ).If i get the photos small enough then i would like to know what the boat is an then i can give it some fittings and a face lift.  In the mean time i have some photos here of some 1/8 scale trucks i made that i’d like to share with you. 

thank you for your interest Chas

All the best Glen

Hello again Chas

Have worked out how to get these photos down to size without any programs other than windows XP so here are some of the wiring.

I guess the red is positive , green the negative but whats the yellow for and where does it plug on to.Chas i gust spent an age with this computer getting pics and a lengthy text together only to have it rejected cause it was to big so here goes in a few passes bear with me please Glen

Hey Chas hang in there nearly done mate.

In these photos will give you a bit of idea of her size .Shes 985 mm long and 225 mm across her widest part. if that 3″ door equalled 7′ then i reckon her overal length would be about 90 odd foot long ? Photo 2 shows where the 2 6 volt bike batteries went and the battery pack and receiver pack. Photo 4 shows the motor and its a johnson 970 rated @ 6-24 volts so i was told but i only ever had 12 volts in it. Hope you can help me with the wiring and also to identify what model it is.

Thanks for your patience

regards Glen

PS any one wanting to shrink any photos and only wants to use windos XP give me a hoy will be glad to help

Hello to you Vinnie

Not sure if many R/C units use recharge Ni-Cd’s these days most of the younger blokes with their cars use standard AA type and buy new ones as needed. The Nickel Metal Hydride sound the part do they come in AA type size and what would be the cost I’d need 12 @ 1.2 volts (if I get my radio workin that is). My thoughts often go back to my earlyer boating days when the batteries must of been getting low on power and my boat just went off  down the lake at full speed occationaly  doing the odd donut, ignoring my calls and jestures.  I left my wife to keep guard on one side of the lake  and I took the car to the other side .Eventually we got it much to all the bystanders delight. Anyway Vinnie i havent had any thing but NiCd’s but willing to look at all bets.

All the best Glen  

Hello to Revell Walker & Len Ochiltree

Firstly  Len is right . I’m in Australia and I’m not sure of the channels for boats and aircraft but my old radio gear is a X plane-aircraft type and yes Revell you are right I don’t want to hassel any one with a plane while using my boat. I would of liked to use it but havent got a problem with buying a new one but would suss out first this 2.4 gig sets that Len mentioned cause if I buy the right gear now I’ll have something worthy to hand on to the grand children  later on.I did buy an Australian book the other day called Radio Control Modeller. It covers a lot but is aimed at the aircraft sceen. Its got prices and gives me a direction there. Will start on the boat soon and once going will probably build another boat Have been bitten by the bug after seeing the keen models on this site.Have sent an email to a few english sites to get an idea of prices for kits and plans but haven’t gone any farther yet. Plenty of time get one thing at a time working and enjoy each one Thanks for your replys guys ang will look forward to talking to each of yous as time permits. Revell the boat of yours that I saw being built is first class and will be great. I’m no expert but I think its a winner already

thanks again to you both have heaps to say but must go now see yous soon

All the best glen

Hello rev

Yes thats good advise mate.  I will look up a new  2 channel set  that should get me going quick smart  Now I need to get my finger out and get the boat shipshape. Thanks again

All the best Glen.
