[NSRCA-discussion] Fuel Weight - unsponsored opinion?

Fri Feb 17 15:48:50 AKST 2006

 All good points Eric, there will probably always be glow around, and will be the best choice for many. Glow to me is more of and excuse the term plug and play than electric, the electric you really have to do lots of reading and be very careful with handling and checking and double check components, charging and so on. So many times I have seen guys on the forums asking what do I charge my Lipo's at, these are the guys that won't read and do there reasrch, they will also be the ones that have fires, packs over discharged, over amped and so on.
 I'm definently keep my glow for backup LOL.

Del,
       I have a mail-box-folder full of notes from Electric enthusiasts because I don't rave enough about electrics. Maybe it is because I raised my issues a bit too soon and should have waited until the "honeymoon " was over?

I am not for or against electric. I just see some reporting once in a while that needs to be challenged. I'm not attacking the author of a pro-electric write-up, but quite often the response can get a bit personal, especially from the sponsored contingent.

After Jason won the Nat's with his electric-IMPACT I bought a replica of everything that "they" were all using. In my case it did not match up to what we were all being told. So I spoke out and raised a lot of questions. Now when I write about electrics I brace myself for a rebuttal even when one is not really needed.

Having said the above, I would like to illustrate a "big difference" that I experienced. It may only apply to me but I think it may be the same for others?.

In the case of the OS's and YS's that I ran, I always felt that I could fix them at the field as long as it was not a complete "blow-up". I would carry some spares and spare engines to be ready for such an event. I have even been seen "cooking" crankcases on contest food BBQ grill's to "pop" out a bad bearing between rounds. I had the skill and the knowledge to solve most of the engine problems that came my way. If not there was always plenty of supporting advice to help me.

In the case of my electric motors I felt especially helpless. If a motor stopped due to an internal fault it was dead to me. If a controller "smoked" I could not fix it. If a battery was losing power, I had no solution. Everything I knew about powering the plane was now redundant.

I touched a prop on a landing and the shaft snapped. Could not field repair it. I had a gearbox unscrew on a Hacker and twist the motor wires out of the speed controller. Could solder back together it but it was dead.

I think that when we stop burning fossil fuels in our cars and use electricity to power them, we will go through the same thing. I'll also wager that we will be paying more of e-power than we do today for gas!

Regards,

Eric.

P.S. I can still sell my YS's 10 years later. I gave away my Li-Po batteries. Food for thought?

Well I Don't see anyone selling off their used out dated electric stuff so glow power is still the only choice for some. I don't see battery manufacturers truly putting in practice a good battery guarantee that you can count on getting 2 to 3 hundred cycles out of them before they are no longer competitive.  Way to disposable for my sport budget.

It may be cheaper in the end, but laying out the $$$ to get started is the hard thing.(4 sets of batteries, chargers, power supplies/generator).

Electricity is a whole lot cheaper than glow fuel - it's just the darn tanks that are expensive (and heavy)!

24oz is .1875 gallons. Nitro fuel weighs about 7.5# / gal. The fuel weight would be 22.5oz, but, a pound and a half is close enough for government work.

I didn't look up the weight of electrons, but one of my battery packs weighs 2.5lb and cost $740 and I still think electric is cheaper ------- and, it doesen't take creative accounting.                         Nat
