Q. Do I need an in flight battery charger?

A. No - Here is an excerpt from an e-mail from Steve Kiblinger, that will put this in perspective...

We installed a Grand Rapids Technology Engine Information System... The unit includes the Altitude and Rate of Climb features... The unit operates as advertised right out of the box... It has numerous readings that are managed by setting high/low limits and forgetting it... The usefulness of the instrument is just wonderful... We were concerned that the unit would take too much energy from the total loss battery setup... I use a trickle charger on the batteries and the EIS said we had 13.2 volts when I took off... 4 hours and 200 miles later the voltage was reading 12.4 volts and I had run dual ignition and the EIS full time... It is needless to worry about an onboard charging system for the LEU...

Q. Is the single carb version of the engine plans still available?

A. No the vastly improved dual Mikuni version is now featured. See detailed photos here.
