<P>-------------- Original message -------------- <BR><BR>> I agree with Chris. <BR>> <BR>> Other ideas (which you may already have done) to reduce weight for NATS: <BR>> <BR>> 1. Lightened back-plate on the spinner. THE SPINNER IS ALREADY LIGHT BACK PLATE. <BR>> 2. Remove wheel pants. YES, WE ARE CONSIDERING.<BR>> 3. Smaller fuel tank. 14 OZ FOR THE ZDZ 40. I THINK THIS IS THE SMALLER WE CAN GO.<BR>> 4. Lithium battery. I AGREE. THE AIRBORNE IS ALREADY LITHIUM. WE HAVE NIMH 5 CELL NO REGULATOR FOR THE IGNITION AND PLANING TO GO LITHIUM. WE DISCOVERED THAT THE IGNITION CAN NOT WORK OVER 6.2 VOLTS SO NEED TO GO DOWN TO 4 CELLS OR SMALL LITHIUM WITH REGULATOR. <BR>> 5. Remove voltage regulator if you're using one with 5 cell battery. </P>
<P>> 6. Remove switch and plug in each time powering on RX (really need removable <BR>> canopy for this). NO CANOPY. BUT WE HAVE HEAVY DUTY SWITCHES AND WE COULD GO LIGHT DUTY. I WONDER HOW MUCH WE CAN SAVE HERE<BR>> <BR>> Sounds like you're already doing VERY well being that close with a gas <BR>> engine. Hope you make it, it would be great to have this as another option! I THINK WE WILL BE OK.
