It looks like the bore is the same as the DLE-120, but the stroke is a little longer. That obviously means a different crank, rods, and probably a new crankcase. The port timing would be different so the jugs would change as well.

More information on the DLE130

DLE130 test, 1500m above sea level. 106" Edge 540 Demonstrator.Falcon carbon fiber propeller constant ground heat stable speed:
27 X 11, 7200rpm
28 X 10, 6900rpm
28 X 11, 6400rpm
29 X 9, 6700rpm
And, three blade 25x12, 6500rpm

Not too bad for close to 1 mile above sea level.. that's Denver's altitude.

The compression ratio is also up, which is good.

If assuming the same port timing as the regular DLE120, it should prove to be a pretty good stump puller of an engine. Bigger props in the sweet spot of where we like to fly.

Hey, seeing is believing and I'm seeing a lot of out dated,no parts available DLE 120's in the near future for sale.

Any word on price point?

12 to 13 oz heavier than the 120. Will that 1 extra horsepower and design changes make up for the extra weight?

Been running a DLE 120 all season in a Ziroli Corsair swinging a Falcon 27 x 12 carbon 2 blade. I guess the engine is really breaking in and making a ton of power, especially with the cool air now since it is ripping the holy hell out of the prop straight and level. I’ve got to find a good 3 blade to quiet it down, but I really dont want to lose any performance. Any reccomendations?
I’ve been researching but cant really land on any thing.

Thanks

You are always going to loose performance from 2 to 3 blades props. On my DLE 120 I used a Mejzlik 25x12s 3 blades. Nice sound, plane feels more locked in but not the same power when I was useing Mejzlik 27x12TH 2 blades prop.
Plane H9 Extra 300 35% 12k weight. Only IMAC.

About $129 Aud more than a 120

Just installing a new 120. do the ignition plugs have to be pushed on like on the 35ra? where you end up with a dent in your palm for a couple weeks after? I put them on, and pushed pretty good. they seem on there good, i cant just pull them off without some effort.
Just double checking as i dont want to put that much force on them if i dont have to.

As long as the cap covers the hex part of the plug you're good to go. Use a small block of wood to push them on the first time or two. Why damage your hand?

I've tried using the gasket that comes with the engine but after 15 or 20 hours of running, the gasket shrinks and the header becomes loose. I also use permatex high-temp RTV silicone gasket maker and it works great. What is everyone else doing with regard to this?

Normally the trick is to when the is nice and hot shut it off, ie after a flight and then torque them up, But you must have nice clean bolts and threads, After you do this afew times it should never come loose as the gasket has compressed to its final thickness and the bolts when get tighter when the cool down as the contract.

I use the gaskets that DA sells. It is a better gasket material than the OE DLE ones. Never an issue.

Or get some auto gasket paper and make your own

But yes pre made are much easier

1) So why would anyone buy a DLE-120 when the DLE-130 is available?
2) Are headers that fit the 111/120/130 interchangeable?
