Dear JetsMunt dealer,
As you know, currently the fuel pump is the component on the RC turbines
that is the cause of most of the problems. The cheap motors used on them are
unstable, wear fast and are difficult to control accurately.
We have been working the last two years in to solve this problem, and
finally we have succeeded in our efforts. We have developed a new pump that
uses a brushless motor, and the electronics necessary to accurately control
it. The pump has been designed and is manufactured in professional grade,
ready for to run for many hours without wear. It has ball bearings and
automotive grade seals.
The use of a brushless motor gives several benefits. No brushes to wear or
to contaminate, in fact the pump run the same submerged in fuel, and full
digital control, meaning that the ecu control exactly the speed that the
pump run, in a 1 rpm resolution. In RC turbine use, the improvement in the
engine running characteristics is brilliant, start-up is always the same
independently of if the pump is new or used, if cold or hot, if Monday or
Tuesday!. Once the engine is started, the rpm control is greatly improved;
stability at idle and all other throttle settings is very good, allowing
changing the thrust quickly but with great precision.
Very soon the M100X and the M140X will be available with this new ecu and
pump. Price will continue the same, and during some time we will offer to
customers the option of pump type, but from our experience in our test
planes, we think that quickly the brushed pumps will be a thing of the past.
Deliveries of the M100XBL will be from June, 10 and the M140XBL in June, 17.
So the M140XBL will become our (and world) first "full brushless" engine
(starter and pump). The M100 will receive the brushless starter in later
date, together with a performance improvement.
The VT80 will continue as now, we don't want to do anything on this engine
that increases the price. The M160 will be upgraded to 200N later this year.
Best regards,
Jets Munt Team
