making a signal booster
I am thinking of making a signal boaster for my FM transmitter (for audio purposes, not related to r/c)
currently my fm transmitter signal transmission is very weak and there are a lot of distortions on the receiver side.
Is it possible to just do a simple add-on amplifier circuit (comprises of a op-amp, maybe) on the end of the antenna wire? or the whole transmitter circuitry needs to be redesigned?

cheeyw... correct, the whole thing needs to be redesigned, and be aware, though i think you know... modification of the RF circuitry of any RC transmitter without a HAM license is illegal in most of the world

Just add an RF amplifier before the antenna.
Here's an example with two RF Amp stages:-
4 Watt FM Transmitter
Or if 4W isn't enough, try this:-
40W broadband VHF RF Power Amplifier for FM broadcast
