L'enfant Terrible du RCIndia

In the good old days when we were building tow line and chucks, the art of trimming the model was drummed into us. It sounded boring and we paid scant heed. As long as it flew, what the hell?!

Here are some fine examples of beautifully trimmed models. An art by itself, it makes Radio Control seem lame.

It is dying a natural death with the profusion of ARFs/RTRs and Radio Controllers.

I plan to resurrect it with my Hobbyzone Champ. I want it to do a full circuit and land near me when I take my hands off the controls.

How do they perfect the synhronisation of rotors.

That is truly a great art.

IN THRUST WE TRUST.....!!
Talking about trimming....  Me and my uncle are working on a chuck glider...  According to him back in the day there were hunter kits available that when launched in head wind would do a immelmen turn and glide in tail wind... 

As of now we are able to get the immelmen turn but it keeps climbing and stalling in its glide path.....

Any suggestions for trimming that...?.??

Practice, and only Practice will make you perfect

Even in rc models trimming is an art, trim changes with, type of Aero foil, cg, Centre of pressure, use of flaps etc. a good aeromodellor will and need to trim the Aeroplane in all conditions of flight, this art too is IMHO a lost art, today people trim once and don't touch the trimmer after and blame the airplane for not performing. Yes, trimming is indeed a lost art,
