There's obviously a lot of money to be made if the come up with a header that will work so maybe they will. At my field you have to either have a canister or a 3 bladed prop, and I don't want a 3 bladed prop.

That's exactly how my DLE55 on MTW can starts. And in summer I only have to use choke for the first start of the day.
A year and half old engine, so can't comment on reliability yet...

A lot of DLE's work well. I think the difference between them and DA is that you have much higher chances of getting an engine that has a bad tendency that just can't be fixed.

k! Al this dle talk in a da thread is horribly annoying.

Go to the dle threads and tell each other how your engines start.

It's a very funny thing how a DA doesn't need a Bowman ring.

Boy the DLE's and the Bowman ring - hummm Sounds like DLE is missing something...
Guess that makes em better somehow?

Don't get it..

hrm...

I think the da-70 will cost the same as the DA-85, weigh more and put out less power...

...but run smooth as silk compared to a large single. My guess is power equal to the 60. The fun will be trying to fit it inside a cowl without hacking it up.

A Da-85 runs smoother than a DA-120, there is a myth that twins always run smoother they don't. I think a QUAD is the only thing that runs smoother than a twin because they stagger fire.

May be if the twin ran staggered it would be smoother but a BOXER twin, nah its not smother.

So the 70 is going to vibrate less than a 85 but its not going to be anything dramatically different.

In fact I saw a DLE-55 and than the same model being upgraded to a DLE-60, vibration was exactly the same (looking at the aleiron tips moving up and down)

i wonder how many folks just swap out their rings for the bowman on per se da's or 3w's?

i guess if it comes from china, buy an engine, then a walbro carb (for those that dont get equipped with walbros) carb arms, rings, crankpins, rod bearings, etc.

no thanks ill stick with my DA's

i wouldnt judge aileron tip movement as vibration. resonance and vibration are two different things. one is the result of another, sometimes.

i also agree the smoothness is related directly to its setup. a single cylinder engine doesnt produce more vibration than a twin, and vice versa.

Yep rotational vibration is going to be pretty much the same since both cylinders fire at the same time. Translational vibration (vibes in a straight line) will be less with a twin.

Not sure if a two stroke twin could be made to stagger fire; I guess the they could if each cylinder had a totally isolated intake path. Since the crankcase is part of the intake system, each would need an issolated crankcase chamber.

easy, manipulate the ignition system. Basic input output system.
