Fast Electrics in the UK II

By Ian and Lee Pearsons

Hi , this is the second article, I hope you liked the first?

Lee thought we could put a "tip" in for junior racers ( and old timers too) to help them to sharpen up so here we go with 2 of them, One for the last article and one for this.

1. While you are waiting to race, you got your boat ready, you are near the lakeside or jetty, hold the transmitter in your hand (switched off of course), look out onto the race of the heat in front of you, pick out a boat in the race, hold your transmitter and imagine that you are driving it yourself, use the sticks, see if you would do anything different, focus on what is happening, this will help you to get ready for your next race!!.

2. Your boat is out on the water racing, YOU HAVE ROUNDED THE FIRST BUOY and is going straight, look ahead to the next buoy, then glance back to the boat, then back to the buoy, back to the boat until out of the corner of your eye you can see both the boat and the buoy, back the throttle off and round the buoy, accelerate away, then repeat the same routine all over again, and for each buoy or boat you come across during the race.

I said I would talk more about the UK Fast Electric scene, the main issue for many of the top UK racers is the World Championships, this year in the Czech Republic at Duchcov (the last home of Casanova the famous, ladies man?..) well the date gets close and preparations are gaining momentum.

The classes that the UK will be entering are various, with the great debate being the "BRUSHLESS or NOT to BE BRUSHLESS"? Controversy for the 7 and 12 cell classes.

The motors from the European manufacturers, (Kontronics, Pletenburg and Graupner, are being designed specifically for NAVIGA class racing, (4 and 5 min. racing), but are very expensive even here in the UK! but these motors seem to be the choice of the Germans, French and Italians.

Some of the English, (including myself) have gone with the AVEOX even though the company have little experience with their motors for this "enduro" type boat racing, and those who have gone Aveox brushless have all got various motors here in the UK, they have all gone with something slightly different, some are finding it a struggle to make the clock (330 sec’s) with a drain of more than 24 amps! so to get the runtime they are having to get smaller than 40 mm diameter props, which as they get smaller become less and less efficient but less load on the motors!.

The opposite seems to be the case with the milder softer winds, as there is a surplus of amps, big diameter props are needed to get the speed and to overcome their low R.P.M. per Volt, this causes unusual handling and prop walking to overcome due to this, still, it seems that there is a general exchange of ideas and results between these guys and hopefully it will sort itself out.

The 1997 World Champion 12 cell Mono was a Czech who ran with a Aveox motor, although the actual type seems to be a secret (I don't blame him!), but I bet the other European manufacturers are hot on his heels this time.

This seems like a good time to talk about the type of racing here in the UK, over the other side of the pond its called "ENDURO" racing, (but even then I dont think the race time in the US is 5 mins.), here in Europe its 4 min hydro and 5 min mono, Hydro 1,2,3, and Mono 1,2,3, not forgetting the Eco classes.

These races are preceded by a "MILL" time, This is the lead in time to the start of race after the signal from the Starter to "go", Ill explain, the boats are on the jetty, and what the starter would say…. "Are your boats ready". "Place them into the water".  "At some time in the next 10 seconds I will give the signal to start". (The starter will decide on the delay time he wants), Then say "GO!". He will count down from 15 seconds like this," "10"5,4,3,2,1,GO" or "clear", The race boats have until the 0 or clear to get to the line but must not cross it!, if you do your first lap will not start until you cross the start line again, or, at the end of the race 1 lap is deducted from the final count.

The idea of this type of start is that it helps to eliminate the usual first buoy "pile ups" from a drag start, there are some who would say that after watching both type of starts there is little between them in respect of collisions!!!.

Perhaps the answer is a 5-second-staggered start, with electronic timing to sort it all out at the end would be the answer? Still would that REALLY BE RACING!!!! Or just time trialing.

Hopefully there should be some photos of last year’s boats, two of them in action.

Well that's it for now, as before this article is only my ramblings, hope my views haven't upset anyone, and look forward to your feedback.

Cheers for now, Flat out, turn right.
