I'm also not keen about flying over salt water marsh,
Water's bad enough, but salt water of any kind & my heli would stay in the Truck!! I see on a daily basis what effects salt can cause, No place for Heli's!!

PaulH & All

Many thanks for the info guys! I recently bought a G23 ( which I guess I messed-up by buying it!) and I plan on putting it in a older X-Cell 60. I too look forward to some operational tips and any information on Gassers!!

Thanks!!

Brian

Most GASOLINE powered heli's will state a gas engine or petrol engine.

There is nothing in a 30 size that is gasoline powered.

If it has an engine it's probably a nitro, unless it says GAS, GASSER, PETROL.

i.e. if you can't tell, it's nitro.

Default Too much power

Bull1965,

As long as you're not adding too much weight, a little extra power is NEVER a bad thing. I've done R/C for around 20 years now and many times have been saved by having extra 'punch' out power. You may not use it right away, but you will one day so you might as well have it available.

Ken.

Anyone looking for a way to calculate their oil/gas mixture, there's a cup I used during my motocross racing days. It's called "Ratio Rite". It cost like $5 and you should be able to find one at any Honda/Yamaha/Kawasaki dealer that sells dirt bikes, or easily online.

It has lines on it to show you how much oil to use for different ratios per gallon. Makes it super simple.

Quick and easy formula to remember.
Just divide units per galon or liter by the desired ratio.
Example: let's say you want to mix a 40:1 ratio
40:1 would be 128 divided by 40 equals 3.2oz oil per galon
40:1 would be 1000 divided by 40 equals 25ml oil per liter
25:1 would be 128 divided by 25 equal 5.12oz oil per galon
25:1 would be 1000 divided by 25 equals 40ml oil per liter
Sure the ratio right mixers work great but if your without one you can figure out any ratio out. If you want to mix half galon or liter just use 64oz or 500ml divided by the desired ratio.

Quote:
N (1550): 0, 20, 22.5, 25, 100
After i set the curve 0, 25, 50, 75, 100 it's like normal.

It looks like the carb response goes linear. Any ideas?

When you say it won't hover what do you mean? What does it do?

With this curve:
N (1550): 0, 20, 22.5, 25, 100
The main rotor starts to turn in the 3/4 throttle position. In the mid stick (2/4) no turns. And the heli is hovering almost in the full throttle. Nothing more.

The needles
H 1.75 turns
L 1.5 turns

Almost finishing the break in.

I think you need to adjust your linkage and endpoints. Take the aircleaner off and watch the butterfly for full movement from 0 to full throttle.

I did. The butterfly opens perfectly normal from 0 to 100. In 0 throttle, the butterfly is almost close. In full throttle, it is full open. Like my nitro. Is this wrong?

Maybe you wore out your clutch liner?

What does " N(1550)" mean? I assume the "N" means normal mode but what does the 1550 mean? Head rpm set in the governor? If your governor is on and set to 1550 rpm the throttle curve set in your tx does nothing and the governor controlls your servo. If that's the case check your clutch.
