You guys are killing me...

This will be moved into the Manufacturer's forum, just like all advertising that I run across...

I've said this before...most of us Mods have real jobs, we can't sit on here and surf all day.

Re: MLD-28 gasoline engine 28cc

My bad on posting in the wrong place. Jeff was cool in moving it to the right place. The engine includes everything from electronic (auto advance) ignition, mounts, template, wrench, side muffler and hardware. The MLD-28 (MLD28) is a gas engine designed to rival that of OS FX160 (160FX) and FS200 (FS-200U), but at with a street price, $299.99.

Conceptual requirements behind MLD-28 (I believe we reached most if not all);
(1) Improve fuel cost
(2) Easier cleanup
(3) Push 3D performance envelope
(4) Increase power to weight ratio
(5) Turn lager diameter prop
(6) Maintain vibration expectations
(7) User/start friendly
(8) Retain high RPM capability
(9) Price friendly

The airplanes that MLD-28 was designed around;
Aeroworks 80" Profile Extra
Aeroworks 72" Yak54 QB
CA Models (Aeroworks) Genesis
Cermark / Topgun Spitfire
Cermark Scale Series 70" - Edge 540
Cermark Scale Series 70" - Extra 260
Cermark Scale Series 70" - Yak 54
DPM Extra 330L
DPM (Dave Patrick Models) Piper PA-18 Super Cub
DPM Piper PA-18 Clipped Wing Super Cub
Extreme Flight, 74" Yak-54 1.60
Hangar9 1/4 Scale J-3 Cub ARF
Hangar9 P-51D Mustang 150
Hangar9 P-47D Thunderbolt 150
Pacific Aeromodel Clipped Wing MonoCoupe
Pacific Aeromodel Gee Bee Y 84"
QQ 73 in. YAK-54

Re: MLD-28 gasoline engine 28cc

$300 is a good price, that's what they cost from at least one Chinese box-dropper.

I just dislike side-draft piston-port engines because of the issues they sometimes have with turbulence inside the cowl or the way you sometimes have to ugly-up your cowl to fit them in.

Re: MLD-28 gasoline engine 28cc

Here is video that we put together with Cermark's new Scale Series 70 EDGE 540 with a new MLD-28S engine. The video is a composition of the 1st 3 flight of the airplane with a brand new (not broken-in) MLD28 or 28cc gasoline engine.

Here is the link:

Re: MLD-28 gasoline engine 28cc

Steven,

I hope the MLD28 has more output than the SPE26. I'm running a SPE26 in a 70" Cermark Edge 540 and would have to say the performance is boarderline disappointing. I"m located in Canada and at our altitude this engine is not very well received around here due to it's inability to turn a 18 "or 17" prop at a productive RPM.

I hope the ignition on MLD has been reworked as well, because I went through two on my SPE26 before my plane even got off the ground, and am now using a RCEXL ignition.

In the promo video, you will notice there are never extended shots of this plane pulling any long vertical uplines, it doesn't have the jam to do it.

Food for thought.................

Glenn

Re: MLD-28 gasoline engine 28cc

I have yet to see one, one being in the small gassers in the under 30cc range that runs like a bat from hum unless the plane is around 9 lbs or less for most flyers needs

Re: MLD-28 gasoline engine 28cc

Flyer88, I also have the Cermark 70" Edge but I have the MLD28 and I have a friend with the SPE26 and I can tell you there is a considerable amount of difference in the power. Both our planes weigh 10 lbs or just a hair over. His will just barely hover the plane at full power. My MLD28 will hover and half power and has very good pull out. I also have the Cermark 70" Yak with a OS120AX and I love it, but the MLD28 is diffinately stronger.

Re: MLD-28 gasoline engine 28cc

Bluehawkbm, thanks for the info. I've been thinking of grabbing one due to the fact it bolts directly up to the 26 mount, and I won't have to do anymore cutting to my cowl. Thanks for the update. I'll wait for them to arrive at my LHS.

Cheers

Fly it Low !!
