    Problem with Skysport 4 transmitter TV4F
    Ah! OK see what you mean - low self discharge.πŸ‘ But at least they are honest enough to warn of the drawbacks! Should be fine for TX power thoughπŸ‘ BTW It's not really recommendable to charge any NiMh at more than 1A, despite what it says on the case! Fast charging shortens the battery's life, reduces the number of cycles and the maximum capacity. Cheers, Doug

    motor rotation indication
    If the reason for an LED indicator is that you want to be able to tell when the motor is still going, but very slowly, then a simple LED will not be very bright when the pulse rate is low. You could smooth the pulses with a capacitor to keep the voltage up - a bit or experimentation may be needed (1uf?) - or go the whole hog and use a latching circuit, perhaps with a 555?

    Fishtailing
    Ron, I was referring to posting videos so that we could all see them. You posted this question- "I have two videos but am not sure how to post them on youtube. Is there anyone who I could send them along to? " I sent you a PM offering my help and asked in this thread how big the video file is. I got no response to either except "Are you on Facebook?" Doug 😎

    Mixing throttle and rudder
    I did this, well sort of, by using the settings in my transmitter, which at the time was a spektrum DX6i. You use dual rates, and exponential settings, I would imagine most modern 2.4 sets have this feature. In simple language, dual rates (D/R) will limit the throw, so by experimenting you flick the switch, and all of a sudden you have limited the throw of the rudder, flick it back for slower speeds and you have full movement. Exponential (expo) nulls the centre stick movement, and is generally on the same switch, so it makes the stick (rudder) in your case less sensitive, so easier to use at higher speed. Just remember though, most transmitters and receiver have aeroplane terminology, so, if your rudder is right stick, this is labelled as the aileron in the instructions, menu and so on

    Martin Westquay's Piper Cub ;-)
    Hi Martin, most of us played with the Keil Kraft & Veron kits in our youth. The small kits fitted the pocket money slot very well - most succumbed early - have memories of Jetex units climbing away from your new model on their own - never to be found. Others succumbed to the force of a penny Ronden "Flash Bomb" lit on launch - spectacular. Then there were the larger kits - rubber powered built with fathers assistance - home carved propellers - which flew out of sight - also never to be seen again. One climbed out on a thermal until a dot in the sky - turned up on a farm 20 miles away unscathed - always had name and address/phone no on a small card on the models.....Later the usual ED Bee's , Allan Mercury 1.5's etc . Watched a 40" span Piper of mine trying to take off with a friends clapped out Bee - ran the length of the rugby field and lifted just in time to intercept the posts............ Have 90% of the flying scale model plans - always mean to build one but designing and making commercial kids kits on the Laser intervenes. So far Land Rover series 1 , Defender, Suzuki SJ410 , Generic Jeep, Willys 1946 Jeep, Pitts Special , Tiger Moth and Eurocopter - all made with 3mm MDF - either fully designed or heavily modified by myself.

    futaba radio and receivers
    I also have been using Orange FASST Futaba RECs since they first came out and have never had an issue with range( far as you can see). Also the Corona R6FA, R8FA and the FRSky TFR6 7ch have been faultless as well. I've been using a Futaba 6EX with all of these since 2010 with no problems. Also been using a few FHSS radios for ground use (boats) with no problems either. There don't seem to be many 3CH FASST receivers but a 4 or 6CH FASST should work ok. A 6CH will work on 3,4,5,6,7,8CH RECs (you only run out of switches if you use a bigger one) Corona makes a R4FA but HK doesn't sell them now. plenty of Corona 6s and 8s around for about $ 25 US. I notice that the Futaba 3PK is discontinued so samc may want to look at a newer radio.

    Pictures of American river boats...
    Hi all, a friend of a friend, hoping to raise a few bob for a dog rescue centre has several pictures in black and white of the lovely old American steam river boats with some descriptive paperwork. Is anyone interested in a donation in exchange for these? Cheers, Martin

    Caldercraft Clyde Puffer Motor and Prop - Help Needed
    Looks like a standard 385 - its high torque - slow motor with 5 poles - just what you need for the slow scale speed of a puffer. Low current draw too - gives nice long run time. Prop normally 3 or 4 blade . Try starting with 35mm Graupner plastic - check motor for heating after a few minutes - gives you a bit of a pointer - you will have to experiment as Glynn Guest suggests - take a handful of props with you to the pond. Anywhere from 30 to 45 with different pitches. Could use a test tank outside otherwise - even a slow running motor pushes a large volume of water - the indoor test tank would tend to empty quite quickly. Better halves seem to get a bit twitchy about that. You can attach a fishing scale or similar and tether boat via it to any convenient tree etc. That will give a good indication of thrust produced - and you can quickly find out what the motor does heatwise.

    Direction Finder
    Looks good to me Ian πŸ‘ Like an ADF searching for a navigation beacon. DG is correct, it wouldn't continuously rotate on a civilian ship using RDF for navigation purposes. I.e. looking for a specific NDB (Non Directional Beacon). On a warship in the old days it might rotate if the set was being used as a Search receiver. Nowadays the antenna for such purposes does not rotate. Instead a fixed multi-element antenna is used and the detector receiver plots the progress of the RF wavefronts across the elements. Thus deducing where the signal came from. So I reckon your setup looks pretty convincing for an older model DF set Cheers, Doug 😎

    Pond Weed
    Thanks for posting about pond weed control. Biological Control .. best seems to be Grass Carp reported to eat the weeds, we are still investigating. Chemical Control... not allowed to use herbicide as our pond is linked to the River Itchen. However we do use Barley straw extract to control algae. Mechanical Control ... motorised cutters etc are far to expensive and you still have to rake up the cut weeds. In the end throwing a rake out or placed behind roots by guy in a boat and pulling it in is the best solution for us, so far. one in the boat, two each with a rake and barrow. we cut and collected barrow fulls. We continue to use Pond Dye (see biofix and dyofix.co.uk) other shading can be obtained by planting willow trees. Weighted black polythene sheets for 6 months at a time has been suggested as has solar powered fountain or air pumping air bubbles as this reduces infestations and oxygenates the water. Regards, Tall Paul.

    Help identifying this model boat
    Hi Norm, being as how you're in the US and I'm in Oz I reckon it is not much use me recommending a local Oz sail-maker. From what I can gather from other fora (like that? My high school Latin does get some use) in the US a pretty good maker seems to be Carr Sails http://www.carrsails.com/ I am guessing that the cost of a set of sails for your yacht would be similar to those quoted for the Bearospace 'ANNIE'. $225 may sound like a lot but, from what I can gather, his sails are pretty well at the top of the pile. Check with a local sailing club, there are heaps of people around that make their own sails as well as lesser known sail-makers. The club may be able to point you in the right direction. Unashamed plug for the Bearospace range of boats - I have no financial interest. There is a lot of info in these blogs to assist in building and making parts for semi-scale sailers : https://www.rcgroups.com/forums/showthread.php?2990671-Bearospace-Sloop-EMMA https://www.rcgroups.com/forums/showthread.php?2550991-Bearospace-schooner-Irene https://www.rcgroups.com/forums/showthread.php?3294855-Bearospace-Schooner-Annie I hope this can help you. Cheers from Down Under, Terry

    What could this Hull be for?
    Picked up his kit same place as I did - fellow who made them was not intending to sell them - reluctant in fact . Mine is his 3rd attempt I believe - cant check now as he is no longer with us . Think his wife persuaded him to sell them. He was experimenting with molding hulls etc. Think the last one was the one he used for himself. We do some forming with 2mm Perspex - failure rate is about 10% no matter how careful you are so understand why he made a few. The hull is about 2 mm finished size - the superstructure a lot thinner and styrene - not certain but think the hull is ABS. Very few Breede kits around - not sure you can even get a hull anymore - and the plans are no longer available from RNLI.
