hi ,
pls tell what are accessories needed for gas engines that do not work for methanol engines. like i heard that the methanol engien fuel pipe dissolves in petrol. like that what are other thing ?

The main thing I have seen is that people use "noeprene" lines for clunk (inside the tank) and "tygon" for the others.

You need tygon tubing and most important part for the fuel tank is the stopper.

1. You need a gas stopper which is made by dubro and can be bought on tower hobbies or from Radical works in Delhi. There may be other local hobby shops selling this, but i am not sure.

2. You need to buy seperate pushrods. These are made by Sullivan and are made from some plastic. This basically does not carry in any signals that the ignition units produces. Otherwise, it will glitch with your receiver and servos. Basically, if you are installing a gasser on a tri-cycle plane, you will need to use one for the throttle and one for the nose wheel steering, otherwise just one. The pushrods consists of 2 tubes, a red outer tube and a yellow inner tube. There is also a more rigid one which has a blue outer tube and a yellow inner one. The more rigid one is used when the linkages are more or less straight and the red and yellow one is used when you dont have a more or less straight setup. Again, Radical Works in Delhi carries this unless you plan on ordering from the USA.

3. An ignition kill switch is optional but is always safe to have one.

Apart from these 2 things, there is nothing else i can think off.

Hope this helps.

And 2.4 radios are recommended

Really! I wasn't aware of that. Why is it?

In summary, less susceptible to "ignition interference".
