Re: 40'' Seaplane Tender, new build U

Hi MT, sound units are actually for cars but have a choice of 58 sounds from V8s to diesels and are the only ones I've seen which seem to sound ok. You have to go through all the sounds and try them through the throttle range but there are a number which sound ok for boats. You can also plug them into your computer and make a few changes such as throttle sensitivity, turbo sound and volume etc. The sounds are proportional, from starting to full throttle and are all WAV sounds which seem to be split up into small 'samples' and as such, some are not quite linear but are useable. There are 2 different models, One is the 'GT Power' sound and lights model - version 2 (the better I think) which comes with all the pre wired and plugged LEDs needed for a car, (h/l, t/l, indicators etc) and comes as a module and separate speaker, (you can plug 2 speakers into this module for better sound). The other model is the 'GT Power' Car Engine Sound 'mini' which is just the sound module and speaker in one box. This works the same as the version 2 model but at present I'm having a problem with the Mini, which has the wrong model for USB adjustment installed, (sounds can be selected manually on the module but when you plug the module into the comp and open the module control panel, it's for the wrong model, - sound files are still viewable though) I'll have to contact GT Power for a fix (going by their on line help page, they seem quite ready to sort problems out and give solutions) Cost is around $56 NZ for the version 2, and around $ 51 for the 'Mini' version which is comparable to most other sound units available, but with more features than some. Apparently, if you send the GT Power tech/help guy a complete WAV sound file (ie, start, idle, and steady slow acceleration to full and back they will make a sound file for your unit and email it back to you,(yet to try but would be brilliant if true) Units are sold on Ebay, Ali Express and Banggood (and many other model shops) and it's worth shopping around all of them, as there are big price differences. These are also sold as GOOL RC sound units but are made by GT Power. ( http://www.gt-rc.com/en/msgBoard.jsp ) You will see the home page on there. I use a number of their products such as battery chargers, rev counters, etc and all seem very reliable and work well. I don't think they sell direct, but they are sold everywhere. For Rooky Sailors benefit, the motors are Gool RC 540-45T 7.4V brushed car motors which have ball bearings and replaceable brushes (motor is rebuildable). Haven't tried them on the water yet, but the 45T (12000rpm) should be tourqy enough (different turn Nos are available) John B
