Strictly from a convenience stand point. The nitro Heli wins when everything is working.

First flight of the day I ( currently E only) have to set up the gen top off the flight batteries from storage charge (about 7 minutes), insert batteries and fly. The nitro pilots just unpack turn on the electronics, release the fuel clamp, turn the glow ignighter and fly.

Later on in the day I notice some flooded engines bad glow plugs and dying battery powered starters and flight batteries ( for electronics).

I am more than happy to help a fellow flyer and charge their starter and flight batteries.

Who says N and E cannot get along.

LOL, I hope he doesn't forget to fuel up his heli!

They bring them to the field with tanks full.

Yes, but I often charge my batts at home while I'm getting ready to go to the field...

But in all the years I few N's, I never fueled the tank at home, to easy to do at the field.

That point is moot as you need fuel for both helis, they will each still burn it...so twice the fuel consumption or buy two batteries.
Not a moot point. If I have 5 helis each requiring 2 packs a year to be kept in service, and I only fly 3 of them a few times that year, those bats don't have many cycles on them do they?. Lipos degrade over time even with no use. This can effect cost/flight.
With Nitro, you can stop at the LHS and $30 will put any of your Nitro birds in the air. In fact, I have a couple which are not in service because I don't feel like buying bats for them only to have them go to waste. If they were Nitro and I felt like dragging one out one day, no problem.

If you own a single bird, or share packs, of course this is then a moot point.

I believe part of the reason is they fill up after last flight to displace the exhaust fumes in tank from pressurization, to prevent foam pick from being attacked by fumes (if using one) and also I guess it performs a long term leak test on your fuel system.

Band, you are stretching a bit aren't you? If you run a car on methanol, you are running a renewable fuel considered "Green".

If you run an electric car, you are not, or very, very low percentage. Until our infrastructure is changed from fossel, electricity is not considered a renewable resource, and is very very polluting.

The container is the predominant value...and it is made in China.

These are not big points in my mind, but at least give them to where deserved.

What Ed said and also to reduce exposure of the internal hose and pickup from air...to reduce oxidation. And moisture absorbtion of the fuel.

Nitro only wins in your own mind. Here's the reality check (list). These aren't all bad things - these are the required things for a nitro power system.

I'm really not sure about anyone else, but in 13 months on my electric power system I've never had one occurrence of:
  1. fuel flowing into my muffler (can I get an Amen)
  2. hydro lock.
  3. fooling around with a glow igniter.
  4. sh!t did I charge my glow igniter?
  5. is my glow igniter actually putting out juice?
  6. is my glow plug really glowing while I'm cranking and cranking.
  7. check my receiver battery voltage.
  8. damn, that electric guy might beat me to the flight line. I hope my nitro power system actually starts this time. Oops my glow plug must have died again! Time to do that whole ritual again.
  9. fooling around with starting my engine (and getting the damn rod in the starter nut).
  10. Why is this dang motor not starting? Oh geez, I forgot to unclamp my fuel line. Boy do I feel like a dummy.
  11. gosh dang it did I charge my starter?
  12. fussing with needles because the weather changed.
  13. Why am I suddenly running rich or lean? Oh yea, because the weather changed.
  14. engine quitting.
  15. muffler coming loose or falling off.
  16. changing glow plugs.
  17. should I change my glow plug?
  18. air leaks.
  19. clunks.
  20. fuel filter clogged.
  21. check valve malfunction
  22. ring replacement.
  23. Break-in, after break-in, after break-in.
  24. rear bearing replacement.
  25. after-run oil for storage.
  26. dropping the motor for any reason.
  27. too rich.
  28. too lean.
  29. change fuel bottles every 7 flights.
  30. to continue flying, take another trip to the hobby store for yet more fuel (or place order).
  31. to continue flying, take yet another trip to the store to buy glow plugs
  32. clutch broke.
  33. clutch replacement.
  34. clutch liner replacement.
  35. hey Ted, what elevation are we at? Oh crap I guess that means we have less power at this elevation. I guess we can't fly as hard.
  36. Walking to the flight line and my engine quite. Nooooooo!
  37. The funky chicken.
  38. did I forget anything in this list.

Holy cow, all that for a lousy 2 minutes more per flight. Adding up all that time canceled out the added flight time compared to electric power systems.

Electric = charge, fly, repeat, same power no matter what, 24/7.
No fuss, all fun. Good clean power.

My LHS is hit and miss on the fuel department. If I picked up a .50 sized nitro and wanted to go fly one weekend, I'd be pretty chapped if they didn't have some heli fuel in stock.

My batteries are always ready to go!

High Voltage just works better

The list is not as extensive or as common but here are some I can think of for us E guys.

1: Crash which destroys flight packs ( equivalent to throwing out a case or 2 of fuel).

2: ESC has failure, may burst into flames, possibly totaling Heli.

3: ESC's bec fails on HV system passing flight pack full voltage to electronics toasting most components (ouch!)

4: arrive at field only to find you forgot your flight batteries. Other electric Heli pilot has different connectors. (guilty, only happened once).

Other than that charge and fly.

Gees Sam no wonder you gave up nitro. I would too but I never have had that much trouble.
Electric = charge, fly, repeat, same power no matter what, 24/7, 365 days a year.
as your lipo gets older it's output weakens
if you overdischarge it, it becomes garbage
you BL motor doesn't last forever. the magnets weaken overtime

so umm 24/7 365 days a year, Nah it doesn't happen

ever bring the wrong flight pack to the field?
you put yourself at risk of fire
quality lipos are still very expensive

Esc lost it's programming again.

Only have 2 packs...both puffed.

Anyhow, there are many things that are indeed a benefit for e's but you have to weight them all. For me, the higher power to weight of Nitro has the most weight and wins the day. I do enjoy electrics too though...for all the little things they're good at.

look familiar ??

was in sams gallery

not pointing fingers just saying some have better luck (skillz) than others

"this is not a slam"
pointing out that Sam had a nitro. look on the shelf ^^
and if that list he made was true then it would explain why he switched

There's also more potential for RF noise which often goes mis or un-identified. I knew one guy who couldn't fly for weeks and weeks. Turned out to be an intermittant winding short causing what seemed to be a static problem. Lot of coin spent.

eddiscus you forgot to mention burning the field, when your heli comes careening down from the heaven on fire.

What are they on v4 now? Not sure. My fuel is still on v1

I love when esc loose the programing or just don't want to perform that day until you plug in your castle link again. Boy I bet that is frustrating. At least nitro it’s your glow plug or you still have your fuel pinched. I can't say I have had starting issues.

Sam2b yup as mentioned I think you made a wise choice going to E. good luck on that blistering road.

Now that is a good point. Doesn't even have to be an ESC failure. They have gone up from a crash, shorted wire, etc....
Boy, that's the sort of thing that could have your town looking at you pretty negatively. Perhaps we should be looking to come up with some sort of safeguards for this sort of thing.
