My first winter approaches in the new RV. I've been getting a fair bit of air movement inside the cockpit and what was pleasant in the summer months was becoming uncomfortable as the air temperature dropped.
Time to take some draft exclusion measures then......
If i'd started with drafts that equal "10"
- Fitted aileron push tube seals = 6
- Sealed around penetrations for pitot and wiring fuz to cabin = 5
- Sealed around rear edge of canopy slider to fuz = 5 (no change)
- Sealed edges of cabin floor to fuz sides = 5 (no change)
I was getting fed up, so had a really close look and decided to fit the seals in the photos attached and also seal the main wing spar penetration hole with some gaffer tape at the same time.
Difference was dramatic to say the least - I'd say not even a "1" on the above scale now. The only detectable air movement now is a little leakage from the cabin air vents. I'm Happy - Wifey's delighted !
I'm convinced that the real winner here was the seals on the canopy side skirts. They are domestic door "brush" seals that have been fitted under the slider canopy rails. I cut the brush to stand 1/8" above the fuz side and they seal perfectly with very little drag on the canopy action.
