Here is a new engine to be available soon..This is a prototype..25cc..1.9 lbs..electronic ignition..16-8 prop, 8300 rpm...19-8 prop, 7500 rpm..Price, $179...NOT a misprint, more info to follow after some extensive testing...Looks GREAT so far...
Any takers ?

Ralph, this is wonderful news. We need a lightweight gasser that is price competitive. I just bought an electronic ignition module and paid more than $179.

This is not someone's fairy tale, the engine looks very good and parts and service WILL be available...

This would be a good match for a lot of 1/4 scale vintage type taildragger airplanes. I have a Nosen Citabria that could have used a gas powerplant to these specs. and $$! [] But, I'm still happy with my tried and true Saito 150 even though I have to throttle way back for just about everything.[8D]

It has my interests.
Are the RPMs you posted just data furnished to you? or are they your readings taken in Williams at 7000 ft.? Are the readings without pipe or muffler? Is the exhaust system included in the price?

Awaiting more information.

Readings were furnished, I have to get an engine and do some serious testing on my Phaeton 90 bipe...I don't have a lot of information, the rpm was most likely checked without a muffler...Prop was a Bolly...For $179 you will have to get your own muffler, there are good ones available for $40 or less...
Just wanted to get an idea of what the demand would be before going overboard with production....

We are totally lacking in engines that are lightweight AND cheap, there will be a huge demand. How bout a DA50 equivalent for $299, any takers?

If it's $99.00 or less, I'm in.

hi all,

i just started to look for my first gasser and the prices are just ... [] well, U know!

i need a good poweplant for a 1/4 Wedell-Williams racer. Specs are for 50 cc...

can anyone point me in the right direction?

thanks,
Vasek

I'm in. Looks good.

I'll buy one. Where can I get it?

doubledee

I wasn't told when, just trying to get a feel for demand.....

Hi Ralph. Sounds like there is plenty of interest. I'm going to build (assemble) another "Kangke" Waco biplane. This sounds like a good engine for it. I'll take one if they are up to your standards. Just email me when it's ready or give me a call. Bob

I too am interested! Please keep us updated!

nah, not interested. but i have to admit its a realy good price.

Any name given it yet, or will it be an RS25 (Ralph Special) The specs including price make this engine look real intresting. Will it be fitted with your ignition or some other.

How about a few more pic's Ralph? Looks promising.

Put me in for one.Heck at that price maybe two for a B-25.

Ralph, it appears that a good part of interest rightfully stems from your quality standards for your ignitions and conversion ability.

The main reason I don't have more big gasser planes is the price I have to pay for the engine. I have one gasser, a G-23, great little engine, but would love to have more than one. Currently I have pulled the G-23 from my Super Stearman, and am installing it on my GP Giant Big Stik. I would certainly like to have one or more at that price.

I haven't seen one apart...Yet....
Castle AFB is the West Coast location for the IMAA meet on Memorial Day weekend.....I'm trying to get one in time to make it...We'll see what it looks like and go from there...

Looks good - what about prop extensions - 4 to 6 inches - available?

It could be done, but would need an extension to the case...I once extended a 3W twin about 10 inches...Threaded the front of the case, made a long aluminum tube to thread onto that..Made a long shaft with a taper on the end, but a bearing at the end of the tube..Worked fine, just a lot of extra work...

1.9 pounds? Seems pretty light. Is that number the weight without muffler, standoffs, ignition? I just bought a SPE26cc, which looks very similar to your engine -- and I thought that engine was incredibly light at 2.4 pounds.

The back of the case is flat and square, no standoffs needed.
The 1.9 (30 OZ) is as pictured...
Ignition is about 4 oz, muffler 3 or 4 more, depends on the brand...
Engine and ignition, 34 oz..Close to a G26, but no contest on the price...I have not tested it myself, we'll see what it does with my 18-6 Mejzlik test prop...9000 rpm is a hard act to follow
