Air Wolf On 600n

id rather pay £40 for a box of nitro than 200quid for a battery to be honest,

10 mins of flight on a tank and re-fillable. not 7 mins and wait for 2 hours for it to recharge

Yes, but when you have 3 battery packs it's not a problem

For scale I prefer electric as no matter how you set up a nitro heli in a fuselage it always ends up an oily mess inside, electric is clean with no mess, you just have to buy your fuel in advance.

its easy really , the oily mess is produced via the exhaust. how do you avoid oily mess in your car? the exhaust is external , same thing again ill simply build an extension for the exhaust and make it an exit hole, i have access to exhaust making machinery , ie the crazy machine that bends metal tubes in all directions

By not having the engine in the car

In the heli, the carb can and will splutter, so will the head and the baseplate and the manofold and the exhaust back pressure nipple over time.

The other thing that generates mess is the wind blowing the exhaust fumes around the heli (or backwards flight, or inverted flight etc ) - and extending a pipe off the muffler stands a good chance of altering the tuning of that muffler... what effect, if any, that would have on the performance, I'm not really sure.

Not trying to put you off

all very valid points mate , but i cant afford to buy a load of lipo's to be totally honest.

[Boggy]

just give the inside a good coat of 2pac laquer or fuel proofer, before you build it then its just a matter of cleaning up after flying!! there are loads of nitro scale heli's its not that big a problem

[robgt]

Just buy some wet wipes instead
Not to power it with, of course
LOL

or a steam cleaner!!!

thats £28.50 a min. and then loads of doing nothing. with nitro £20 gets you a gal of 30% and that could be ten 15 min flights could be up to 15 15 min flights and that is with a 90 raptor not a 50 size, a 50 would be even better on fuel. that four hours of flying. for less that what would pay for 7 mins. you might get 17 hours out of that battery but it would take you two weeks non stop flying to get the 17 hours

come talk on the chat

Thats quite misleading and/or wrong in my opinion...
One at a time

thats £28.50 a min.

You're not taking into account lifetime of a pack. If a Lipo costs £200, and you get 200 cycles out of it, that's £1 per flight (which could be around 6 minutes each, ballpark). Some lipos cost less than £200 and will give you more than 200 cycles.
Some don't and won't.

with nitro £20 gets you a gal of 30%

That's right

and that could be ten 15 min flights

On a 30 size helicopter, yeah, in fact, you would get more than 10 flights, and possibly longer than 15 minutes per flight too.
You won't get a 15 minute flight out of any other sized nitro powered heli - currently.

could be up to 15 15 min flights and that is with a 90 raptor not a 50 size

I disagree.
A 90 size helicopter's fuel tank will be filled, at most, 9 times from 1 gallon, depending on the size of the tank being filled. When we're talking US gallons, that drops to 8 at most. I get 7 tanks from a US gallon in my Vibe 90 which has a very large tank (plus header).

You might get around 10 or 12 flights on a Trex600 sized tank (50 nitro) from a US gallon. But you won't get 15 minutes of flying time on a 50 or a 90.

that four hours of flying

I think we've discounted this now?
1 US gallon on a Trex600 (50 nitro size) would give you approximately (and generously) 10 minutes per tank, so 12x 10 minute flights = 2 hours.

1 US gallon on a Vibe 90 gives you approximately 8 to 10 minutes per tank, so 7x 10 minute flights = 1 hour 10 minutes.

I just think it's worth doing the sums somewhere near right - Lipo costs have fallen significantly enough to justify choosing that route over nitro on a cost per flight basis. The downside, in my opinion, is that you carry ALL of your fuel on EVERY flight - and if you crash hard enoughto damage the LiPo, you lose that investment in fuel. For me, nitro wins this argument because of this point.

I did not have a calculator on me last night, so i am flying sat morning i will time my flights and check the tank size and tell what my heli does to the the pound, the point I was making is when you fly with batteries you do more spending and waiting than you do flying with nitro. And I want to fly the thing and get better at it, that has to be done by time in the air not on the ground charging. If I had £600 spare it would be spent on a top range 90 or a 50 and a scale body,..not three batteries.

True
No argument from me there.

im going to go with the nitro , boggy is right if i flash in a couple of coats of lacquer the body is protected it really is a case of cleaning it up
