Give me a date - next sunday about 11.30?

Still got this 'mis fire' and servo chatter. The Rx in the Truman is a FP R118 F (now discontinued) and came with the TX and I have no problems at all, the one in the Kuznetsov is a R 137F. Both are FM and I have managed to establish that the R118F is a Narrow Band - some compatability list or other would be a help, but can't find anything on the Futaba website. Any help accepted

Hi Paul Have you tried changing crystals ?

Just to be sure, you don't have your antenna touching any power leads, leads across prop shafts, etc?

The Kuznetsov goes on the water fairly often - usually to test something or other in a real situation. If you have a mind to take a look at it 'so far' I would be happy to take her to Colwyn Bay one Sunday afternoon to suit you.

General question for anyone to have a go at !!

Still having radio problems with the Kuznetsov and am running out of ideas - does anyone know if Tx and Rx units are matched? The Kuznetsov is built along the same lines as my Truman and I have no problems with her at all - the only differance I can say is the Rx is the one that came with F14 Tx

Paul Bannnon
Hi Paul I would very much like to see your Kuznetzov on the water. Perhaps we can arrange a mutual date ? My F14 Tx and Rx are matched and I have no problems . What sort of problems are your having ? glitches or dead spots ?

Would be interesting to see the Admiral Kuznetsov and the Kiev sail together. Would be a great picture.
I plan when my Admiral Kuznetsov and hopefully the Kiev being built in Wagga come together get some really great shots. Both are at scale 1/72 and hopefully a carrier weekend. Can you imagine at scale 1/72 sailing together the USS Enterprise (Fitting out), Admiral Kuznetsov (under construction), Kiev (under construction), Giuseppe Garibaldi (Sailing), Lexington (under construction), Graf Zeppelin (under construction) and Shinano (on the drawing board).
All we need then is a camera..... :lol_3: Can't wait for that day to arrive.

Yes, 2.4Ghz is the way to go, expensive though and not yet to flexible. On the Truman I have stuck to 40Mhz using a Robbe F14 Navy with a Multi prop decoder, an Action Electronics 4way relay box and a duplicate Rx.

This gives me 6 channels on the Tx, 8 channels on the De Coder - one for each lift, remaining four driving four servos with two latching push switches giving control of further 8 curcuits - giving a total of 18 channels, and 22 controlable curcuits - well within the capacity of an F14 set.

The Admiral Kuznetsov will follow the same ideas, I have just ordered the De Coder.

I sail with six other builders on a local private lake, usually on a Friday afternoon - can't really give more detail over the open net. It;s about 25 miles East Colwyn Bay
Paul Bannon
I also have an F14 , great unit if not a bit bulky . I have it dedicated to the Kiev. Only use 4 channels, I thought of having working lifts but I would have had to make more compromises to the build than I would have liked. Perhaps when your ready for the water you could bring your Kuznetsov over to the lake at Colwyn bay . I'm only 40 mintes drive away.

A bannon . How many channels are you using ? Have you changed over to 2.4gig? I ask this because having working features 2.4 gig ensures that any chance of a clash of frequency is now very low . Where abouts do you sail and are you far from Colwyn bay ?

Forgot a bit of info - Motor is driven through a double pole, double throw, non latching switch operated by a servo on proportional control. Move servo one way supply on two contacts (+ & -) passes through micro switch to motor, motor runs until micro switch breaks, motor stops. Bringing servo back to central will also stop lift at any point between top and bottem. To move the lift the other way the change over switch puts + & - onto the motor the other way around - lift goes opposite way. Can do wiring diagram if this is to awkward to follow. If you connect a small relay to the motor supply you can have bells and whistles working as the lift moves. On the Truman I have flashing yellow LED over door, well lights and a beeper !! Relays are not polarity sensative.

Not to difficult, pic's below should be self explantory. As the lift well projects into the hull and the main sliding slot is inside the hull the rack and pinion system works very well - very positive. The slot is cut right through the lift well, piece of styrene with a small piece at the top at right angles. The right angle bit fits through the slot, when racks fitted I joined these small pieces with a 'beam' to take the lift deck ( you can see filler to get lift level) Screwed the deck first and when happy will fill holes and paint. Top and bottem micro switches are shown - as lift comes up switch opens, motor stops - same going down - pivot switches to get stop point. Did find that the gearing stored some energy and ran on a little after motor had stopped put dense foam on actuating arm to compensate. The cables will (I hope) simply go up through drillrd blocks and hang over into the hull tied to lead weights to keep tension and give impression of cable operation. Much easier and more positive than thos I did on the truman - simply because the lift goes into the hull rather than being totaly outside.

Any questions - just ask - do my best to answer

I'm very interested in how you plan to get your lifts working. Could you post a simple diagram of how this will work?
Mine has slowed again but very soon some mode MAJOR work will happen. Once this gets done I will be able to finish the basic hull. At this moment I can't even move it. I want to make sure my landing deck is perfectly level from bow to stern and port to starboard. Gonna be fun :twitch: (except for ski jump of course)

Hi Mick

Going very slowly at the moment - been rather busy with other things. Have got the aft lift fitted and operating and work on a smoke unit is underway coupled to a speed controler to give automatic operation - got to play around with the length of the heater element to get the right volume. Next job will be to build the forward lift, simple repeat of the aft one and then the arials - aim being to get all 8 working off one servo - ultimatly all HF arials will go up and down under Rx control as in the Truman. Overall she doesn't look much differant to the last posted pic's

Bit slow replying - ferite rods would appear to have cured problem but we now find that there may be interferance were we sail - four boats all lost signal at the same place and same time - will take some nivestigating

Set up is basicly as follows:- Futaba F14 Navy Tx operating Futaba 6 channel Rx operating 2 Viper 25amp ESC's,2 Como Drills moters per ESC, each moter with 2;! reduction attached.

Have been told I MAY be getting feed back from ESC's to Rx and should pass leads from ESC's tp Rx through Ferite rings ???

Paul Bannon
This could be a possible course of your motor problem. Also you could surpress the motors and reduce the interference from that source using a suppression kit. I've used a number of different types of motors over the years but have always selected Electronize for my ESC and have experience no problems. Let me know how you get on ?

Sorry, I somehow missed your question about Davits.If memeory serves me right I worked i out from one of your pic's - one of the port side in the area of the boat decks - no boats are in place and if you look carfully one set of davits is in the upright position and one in the down. From this I worked out where I was sure the 'hinge' was.

As I said KZ has gone on hold for a while but I do have a problem with the RC if anyone can help. I have what I can only describe as a 'mis - fire' on the moters. It's accross all or any moters at the same time - as if they had been switched off and straight back on again so I can only assume its something on the line Rx backwards towards Tx. Have fitted new crystals in both Rx and Tx and been through the conections numerous times. A couple of times I appear to loose all control but on getting close and checking the rudder servo is still working - I just loose the moter control.

Any ideas greatfully tried.

The boats will not actually lower down - thats going TOO far but I agree about the motor etc. If I can remember my seamanship the bow and stern cables have to lower together or the boat jams on the way down, also there has to be a system of release that ensures the bow and stern of the boat drop free at the same time. Again, if my memory serves we had to hit a ring with a hammer that freed the hook which held the bow and stern cables allowing a level drop - in theory!! Thankfully I never had to try it for real.

Don't mention Airwings - it's going to get an odd half dozen and that is IT. When the undersides are done on the Kuznetsov she is going on the shelf while I finish a half air wing for my HST - it's not just the aircraft, there are over 2000 Pad eyes to put down, 10 tow tractors, tow arms and chocks, not to mention chains to tie the aircraft down - perhaps it's 11 years service in the Fleet Air Arm that has caused a lack of interest in aircraft!!!
