Wheel pants for RV

Recommended Posts

Dear colleagues, can you tell me how much are the wheel pants for the RV in demand?

Which material is preferable - fiberglass, carbon fiber?

They look beautiful Meglin.  Pity I don't have an RV but plenty do.. More so in the SAAA. where the weight limit doesn't restrict like it does Here .   Regards Nev

Vans supply fibreglass wheelpants. They are optional kit items but nearly every RV has them. Pilots sometimes don't install them if they are flying off grass or rough surfaces but you won't find many RV's that don't have them.

How good this work can be objectively judged only after:

1) comparing the weight,

2) comparing the condition after five years of operation in harsh ultraviolet conditions.

Heated fiberglass epoxy provides significant advantages on both counts.

Those are very impressive wheel spats. 

I built my own, which are not as neat, but it taught me to admire good workmanship when I see it!

In our slower aircraft, well-designed spats can reduce drag as much as a retractable undercariage.

My flight tests showed a reduction of up to 13% in fuel burn.

On the RV-12 which cruises at 110-115 knots they add about 4-5 kts to the top speed. On the faster RV’s that cruise at 150-170 kts I believe they account for about 9-10 kts.
