TOPIC: Gas scale unlimited hydros

Gas scale unlimited hydros 2 years 1 month ago #558

Hi

Is there any interest in getting a new class started for Gas Scale Unlimited Hydros? Is the IMPBA possibly looking at adding this class? From what I am reading it is probably the fastest growing class out west right now. Personally I am going to build one and hope that the IMPBA will someday look at sanctioning this class.

Hey Rick. I have not seen any interest in a gas scale hydro class around here. I know they are running them on the left coast and we will see if it gets peoples attention. As of now there are no plans on making this an IMPBA class.

Thanks for the reply. I think it is a great class and will generate a lot of attention in the near future.

Well Rick it looks like interest is growing for the gas scale class. IMPBA will be adopting rules for the class in the near future.

Failure to adequately meet the validation requirements can result in disqualification.

b. Complete all major lettering and paint schemes
c. Gasoline engine and complete exhaust system excluding up to 1" of exhaust outlet must be concealed with fake engine or cowling as per prototype boat.
