This engine sound simulator is principally intended for radio controlled model boats but has also found application in trucks, tanks, cars, rock-crawlers and even aircraft.
The MK3 is functionally identical to the MK2 but packaged in a smaller, lower profile 3D printed case. This marks an amicable agreement with Technobots (the original distributors of my design) to market the unit myself under the Forge Electronics brand - a company I founded in 2012 to market my model aircraft related products.
At this juncture, I have decided to discontinue the seperate petrol/diesel/steam variants and just offer the combo version which incorporates all three types - with the benefit that additional petrol/diesel sounds and many more user adjustments are available for a small extra cost.
The fall in the pound/dollar has significantly increased the cost of the components and as a small cottage industry I also have to pay VAT on the components so the selling price (£30) is necessarily slightly higher than for the discontinued MK2 petrol/diesel/steam variants (£27) but rather cheaper than the discontinued MK2 combo (£37). First-Class-Signed-For postage in the UK is £3.00, elsewhere at cost.
A wide range of adjustments are user accessible via a simple system utilising a pushbutton on the unit in conjunction with the transmitter’s throttle joystick (see the bullet points below). The red/green LED indicates both the neutral and the run conditions and pulses in sympathy with the engine speed when the latter is running.
Users can set the unit to match both the neutral and span parameters of their transmitter joystick anywhere within its 1-2mSec range thereby accommodating forward only systems and pistol type controllers with a 70/30 forward/reverse range.
A further feature is the ‘Demo’ mode which is of use in static displays at exhibitions. This allows the model’s sound capability to be demonstrated without passing the throttle signal through to the model’s ESC – instead, a neutral (stop) signal is sent to the ESC.
- 9 different engine 'voices' to choose from - 8 'petrol/diesel' and 1 'steam
- automatic throttle activated start/stop
- start-up and run-down sounds ('petrol/diesel' only)
- simple user adjustment of
o top speed
o idling timeout period
o engine 'voice'
o cylinder count
- 'demo' mode
- bi-colour LED indicates neutral and run conditions
- option for remote set-up
I've made one example of each of the eight 'petrol'/'diesel' sounds plus the 'steam' - remember that the tickover and top speed can be set to suit your preferences and that for each voice there are four more cylinder count variants to try. If you are listening on a laptop, tablet or even worse a smartphone, expect to be disappointed as the punchy bass of a decent size speaker is required - otherwise they can sound like a woodpecker on steroids !
