ESM warbirds are very good but still not comparable to the level of finish of even the less expensive popular ARF jets coming out of China nowadays.... The only true "ARF" warbirds that are similar in my opinion to the current ARF jets in level of detail are Yellow Aircraft ARF warbirds. Yellows Spitfire and P-40 are available as ARF's, glassed, painted with all the rivets nomenclature etc. factory finished. Do these sums and Yellow's ARF warbirds are also into the jet $ league also!!! ESM warbirds are not comparable. Try asking some of the 3D and heli guy's how much they have tied up in the hobby.... And still its cheaper than golf
