Is there a style or brand of tank that holds up better to the pressurization?

Yes,

Tettra Tanks are available from Central Hobbies.

You don't need the Bladder style tanks just the Crank tanks are the normal fuel tanks. The bladder tanks are the tettra Bubbless tanks. They have a rubber bladder inside. Many of the guys that Pylon race use this type of tank. With the YS engines than have a pressurized system, the bubbless tank is not really an advantage.

The "Clunk tanks"

I have used these for years and years never had one fail.

I'm using a Hayes tank. They held up great when I had my 63 and they seem to be able to handle my 110. You can really see it puffing up though.

The Hayes tanks are excellent. They will swell a little. Keep an eye on the front edge where the plastic bends that inside corner. Over time it can develop a small crack. Another option to help the life of the Hayes tanks is to put nylon strapping tape around the tank to help keep it from expanding. The Hayes tanks is what we used before the Tettra tanks became available. They'll work just keep an eye on them.


Hey Ben,

Colorado is my old stomping grounds. I grew up in the area between Denver and Cheyenne, WY. Then attended the U or Wyoming. Do you fly at the Loveair field or the little field behind JAX Surplus?

Its been few years and I don't know if the club behind JAX Surplus is still there or not. I lived in Littleton for many years until about 1995-2003. I used to drive up to Longmont to fly. AI grew up flying models at Jeffco. Fond memories of the area, and lots of modeling friends around there.

Yeah, I fly at Love Air. I haven't flown at the field behind Jaxs because there are too many prairie dog holes and too many houses. We have a new field out towards Ault and it's nice. We hosted the Warbirds Over the Rockies event this year and have a contract to do it for another 4.

I moved up here from TX and YS is the only way to go up here lol. My 63 had amazing power even with the elevation. I'm moving back to TX in a few weeks though. I'll be burning up the skies with my 110 down there.

Brian Omera is a friend of mine since I was a kid. He's a really good scale pilot. I think he was the main guy behind the war bird event. Brian's always been pretty cool. My wife and I purchased our car from Brian's Omera Ford dealership. Its one of the biggest Ford dealerships in the Denver area.


Small world eh?

The reason the YS engines do so well up at elevation is the super charger system.

This is what the US WWII fighters did to handle the High altitudes and have performance escorting the bombers. The P-38 was one aircraft that really benefited from the superchargers.

A similar type of thing is what the YS engines do. Thats why they make so much power compared to other 4 strokes and even 2 strokes on the market.

With the supercharger system the engine doesn't suffer as much from the elevation and lack of air as it would without the system.
