dean , order another set of blades from rob and move your exhaust out let. probably your seals in your gearbox would leak first letting you know that it had been heat effected.

The turbo on my old engine used to blow straight out onto the prop and I"m not sure how many hours without looking at the book this took place for but no problems were experienced with the Warp Drive prop.[ Aprox over 2000 hours.] Mongrel engine though !! I"m very pleased to have gotten rid of that excuse for an engine.

Gents,An Airworthiness Alert (AA) has been issued in response to an incident report on this subject.The facts stated in the AA have been confirmed by the prop manufacturer, another Australian prop manufacturer, Jabiru aircraft and a composites expert from the boat building industry.Exhaust heat is not the only source of heat that will cause problems with composites and dark colours on composite structures are the worst culprits.Exhaust heat also affects fixed wing aircraft like the Quik EZE family and this was with wooden props that delaminated attritutable to exhaust heat.Guess my black Raftor is in trouble.Waddles.

After seeing where the exhaust hits the prop, I"m not at all surprised to hear that damage has been done. On my old turbo set up, it hit the prop some third to half way along and then at an angle so the passing air would dissipate some of the blast but even this left a mark that you could see on the prop.Once again, throw the turbo away and if anyone loves turbos that much, buy a 914 !

Heat from the exhaust didn"t cause my prop to fail down at the root inside the aluminum hub.
