Perplexed ?
« on: July 27, 2015, 10:00:39 am »

One of the great things about model boats is the wide spectrum of different ship types and propulsion systems.  However, there is one rapidly growing trend that leaves me baffled.
Take a high RPM brushless motor, encase it in a water jacket to limit melt down, then add a high current 30S Lipo battery plus a “100A” ESC.  It can be expected to go like a bat out of hell for a very short time.

If you are very, very, lucky it may run the length of the lake without melting the motor: ESC; or even wiring solder joints.   Continued good fortune may allow the Fail Safe to cut the power before the Lipo becomes a Biblical pillar of smoke by day, or a pillar of fire by night.
With a run time that can total mere seconds you then have to wait twenty minutes for a club rescue Springer to bring you back in.

Why?  I really can’t figure what the fun is in a short run time with such a highly volatile pseudo rocket.  Unless you have plenty of spares and extra batteries your sailing session is over for the day. 

Perplexed, I will continue to use big SLA’s and NiMh’s so I can sail for two to three hours at a realistic speed without having to bring it in for a ‘refuel’

Perhaps this is the  result of spending many formative years sat in front of a gaming console playing adrenaline boosting games. The brain subconsciously develops the 'need for speed' and filters into any other pursuits and pastimes the person becomes interested in.

Thanks Dave  (tee hee)

My post was a little tongue in cheek.  It takes all kinds boat challenges, and a lot of posts on these recently. The one I particularly noted was the melting solder joints  %%
