бытует мнение о недостаточной надежности Ротакса-503.
Это мнение тех, кто не летал много и правильно на них.
Из двухтактников (503 и 582)- это САМЫЕ-САМЫЕ надёжные!Нет, не 503и 582 , а только 503 самый надежный!!
[highlight]К вопросу о надежности Р- 582.[/highlight]
Летал в испытательный полет на Бланик-13, оснащенном Ротакс-582. Полет помог организовать A36FLY. И самолет — его. Весь полет проходил на оборотах 6 000.
Взлет и набор высоты — на 6 600. Двигатель не только не чихнул ни разу, даже температура его все время была в норме!
Еще раз огромное спасибо A36FLY за помощь в провдении этого испытания.
Имеющиеся прежде сомнения в надежности Р-582 у меня прошли.

Ребята, сканирование в процессе…
Времени катастрофически не хватает((((
К тому же придется продавать свой аппарат с Р-503…
В выходные выложу в соответствующий раздел..
Если кому интересно будет, заходите в торговлю. Буду продавать недорого
Обстоятельства, нахрен!
Мануал досканирую в любом случае! Обещал хорошему человеку с ником A36FLY

Двигатель не только не чихнул ни разу
А обычно разок другой чихает?
То есть отсутствие чихов для 582го мотора является достижением?
Как же его тогда можно называть авиационным?
Дааа, выходит 503й действительно хороший моторчик!
Вон по 912му уже несколько страниц исписали обсуждая его различные глюки и это у мотора с 2000ч. назначенного ресурса.

А вообще то — типичный пример флуда, Алексей!
Намеренно не замечаете ключевое обстоятельство. Я уже не говорю про уход от темы.
Вы, лучше бы, как человек разносторонних талантов, стихи написали о надежности 503-го и 582-го заодно!

Да, господа, извиняйте… (((
Нет времени дельтом заниматься — начал продавать.

Попросили фоток побольше — не было времени доехать до аэродрома. То ли дни удлинять, то ли ночи укорачивать 
На работе хожу и кошусь на новый скоростной сканер… Скоро инструкция в скане будет!

Для Pilot737. В гугл. есть инструкция для R 503 . Установка эксплуатация и обслуживание. Правда на английском языке. Но мне нужна была электросхема двигателя и цветовая маркировка проводов. Если есть гугл хром , то по запросу найти это всё можно легко. Купил у человека Rotax 503 за 25 т. руб. без документов и родословной, ну и пытаюсь установить его и запустить.

Схему уже выкладывали на форуме пару раз…
Однако ищется она плоховато…
Наверно выложить её здесь ещё раз — будет не лишним.
