<DIV>There are a lot of folks in the Sportsman and Intermediate classes that fly smaller electrics. One very popular plane for newcomers dabbling in Sportsman is the GP Venus. This plane has been extensively covered on the RCGroups electric conversion forums and on RCU. It can be outfitted for significantly less than a full blown 2m ship. There are some new big outrunner motors that are suitable for .90 size and 2m ships that will help lower motor costs and eliminate gearbox hassles. Most people it seems go straight for the 2 meter conversions, so not many .90 power conversions are documented from what I've seen. The Quest is one that I've read about being done a couple of times. Batteries are still the big dollar items at these sizes, but battery performance is going up, so the bang-for-buck factor is getting better. There are also new competitors emerging on the LiPo market.</DIV>

<DIV>You fellows have done a good economic review of the flat-out electric</DIV>
<DIV>airplane.</DIV>
<DIV>How about considering a lower level entry airplane? Are they at all</DIV>
<DIV>competitive price wise?</DIV>
<DIV>Consider something with ONE of those $325 batteries... Is that enough to</DIV>
<DIV>power a 90-size airplane?</DIV>
<DIV> </DIV>
<DIV>Also, I am not believing electric motors and gear boxes run forever. Are</DIV>
<DIV>they rebuildable or are they junk at some end-of-life?</DIV>

<DIV>> If one were to run the numbers for Thunder Power batteries @ $325 each</DIV>
<DIV>> half, it works out to $1300 for two batteries. If you only have two</DIV>
<DIV>> batteries, I hope you enjoy watching other people fly (or take your glow</DIV>
<DIV>> plane). Personally, I consider three batteries the bare minimum for</DIV>
<DIV>> practicing pattern, which puts that at $1950 for batteries only.</DIV>
<DIV>></DIV>
<DIV>> Guessing 200 flights per battery (probably a overestimation), that is</DIV>
<DIV>> $3.25 per flight.</DIV>
<DIV>> Guessing 6 flights per gallon with a 1.60DZ (perhaps an overestimation),</DIV>
<DIV>> that is $3.33 per flight.</DIV>
<DIV>></DIV>
<DIV>> The 160DZ is most comparable with the higher performance electric motors</DIV>
<DIV>> (Plettenberg Xtra 25 and Hacker C50XL), each costing $400. A controller is</DIV>
<DIV>> $250-350.</DIV>
<DIV>></DIV>
<DIV>> Two battery chargers is also a bare minimum. They will last forever, so</DIV>
<DIV>> spending extra on more is a good investment.</DIV>
