Ive seen some of the alternator systems for the 40-70ish engines....

Do they work, and are they worth it? I know that they arent neccessarily needed...but does anyone use them...

I don't want alot of the usual responses here ("I never used one, but i'll sure tell you they're worthless") that i see alot from guys here....

I like the idea of not having to worry about flight time on RX batts...seen a guy a year ago (before i ever bought a plane) lose a very nice scale model because his radio died about 30 seconds before he was landing...just happened to lose power when he was on his approach turn...so it just kept turning down....

Not to mention i can fly all day...i dont get tired of it (Well, i dont get bored watching, i havent had a chance to actually fly mine yet)

This isnt something im looking at for my trainer, but to incorporate it into my next build....

Thanks for any usefull info in advance...
