46" RAF Crash Tender

White it is then. As to it being on the centre line then that may be a little more obscure. It is all down to how the light is observed, its actual visible arc of light. Take a look at how many different positions the stern lights are on RNLI Tamar class lifeboats!! Time to turn in

Mixing throttle and rudder

Thanks. I'll have a play with those Tx settings when I get the boat back on the water, hopefully next week. Currently in dry dock being re-painted. I think the expo setting for the throttle should be useful. While waiting for the paint to dry between coats, I have put together a mixer which, if I have it right, monitors the rudder demand and uses it to impose a maximum value on the throttle input to the ESC. As the turn gets sharper, the maximum throttle demand to the ESC is gradually reduced. That should stop me hitting a turn too quickly.

Hi Doug, Thanks for that. Here are some close ups of the main mast of Cottesmore. The colour and positioning of the lights are from photos and drawings. I am going to have to rewrite my Arduino code for mine hunting mode. That is another mod I will eventually get around to doing. Martin.

motor rotation indication

"....You could smooth the pulses with a capacitor to keep the voltage up - a bit or experimentation may be needed (1uf?)..." Just had a go at this with a Taycol Target on 7.2v - you get a noticeable brightness increase at .5uf - but noticeable isn't the same as useful! 1-2uf is better. 10uf is at the limit, because much more smooths the pulses out so much that the motor runs at fairly full power! I had guessed at 1-10uf earlier, but hadn't thought about what the armature would do with a constant high voltage... It would be more elegant to isolate the indicator circuit by latching the led and resetting as the power went through zero. Or detect revolutions directly with an optical interrupt. Or a frequency-to-voltage converter... but now we are talking about electronics as a hobby rather than model boats... 🤕

EeZeBilts From Keil Kraft

A fellow member of this site saved all the EeZeBilts from extinction by setting up a website - obtaining all the kits or drawings thereof , drawing parts and publishing them free to all. He has done a lot more including trying to save "Orphan" model boat plans in the way Outer Zone and Aerofred have done for model aircraft plans on the Old Boats site. In addition there are websites for Taycol Motors and Adamcraft besides the Vintage and Old boats section of RC groups On the EeZeBilt website is a challenge to produce what he has called EeZeBilt 50+'s being larger models built the same way. So far he has produced most of them ranging from a Steam Launch , PT Boat , a Sea Queen version. Life Boats , Fire Tender and his latest a Russian OSA missile boat. Model Boats magazine has published a few plans in a similar genre lately in A3 sized plans - and a few years ago the story of a build of two of his models featured in the magazine without any kind of acknowledgement. What I would like to do is issue a challenge to fellow members to have a go at designing a new 50+ version over the winter building season . I have been trying for a few years to finish the design of a Miami Crash Boat - SA version R9 which a friend purchased from the SAN many years ago. Determined now to have it finished before Christmas - and publish the plans in the new year. I am willing to help put the plans into usable format (jpg) using Corel Draw for anyone with only hand drawing facilities. Would be nice to see a few fishing boats - more tugs - Cabin Cruisers etc etc.

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.

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 👍 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.

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.
