I have a 27% Extra 300s and I have a G45 in it but was thinking about putting a electric ignition motor in it and have herd yes and no about going with a DA engine or a 3W. I've herd more about DA's then 3W's but I don't know I'm just getting started in gas engines and don't know.

I have both a DA50 and a 3w55......The 3w is harder to tune than the DA.....but I think the 3W has more power. DA has the better customer service.

Both are good engines

Convert your 45 to EI via Ralph at RCIGNITIONS. DA and 3W are both excellent choices, but why not save some money and get some great life out of your 45 since you are just getting started? EI and a good exhaust system will go a very long ways with the 45, and narrow the 'worth it' margin when contemplating the purchase of a new engine.

For this plane, either engine is overpowered and will not even need a pipe to get great performance.

DA engines are fantastic, still good price level, as they are made in the US. Very good customer service and can be found used for $500.

If you take the DL-50, you will get similar performance at a price closer to $300.

Check the weights. DA is built light. The 3W is built strong but heavy. In your 27% plane the flying will suffer a bunch from 3W's weight. But put it in a 88" span newer type 50cc plane and it will shine big time. Better to ask which "one" you should get first. If you go 3W get the rear carb. Learning to do engine mounting around a rear carb isn't that hard compared to having to chop a cowl up to fit around the carb on a side intake engine.

Does this guy have a web site?

www.rcignitions.com however it is not kept up to date, and is not NEAR as user friendly as Ralph is himself. You really want to just get him on the phone! He is a good man to do business with.

His address and phone number were provided above.

I heard that 3w engines are lighter. At least that their twin cylinders are.

http://www.chiefaircraft.com/rcmsec/Models/Model.html Chief shows specs for lots of engines. And are very good people.
http://www.aircraftinternational.com/ The 3W importer/repair center/ one stop 3W palce.

I've also been told that a G45 is alot of power for my plane?

If you want to go to the field and fly and have fun buy a DA. If you enjoy going to the field and working on your motor trying to get it run correctly, buy a 3W.

....some among us still insist on advertizing how little they know about the quality engines available to us in our hobby.

And that they read a word or two, assume they don't need to read more cause they know all thats important and blast away.

Exactly.

I've seen just as many problems at the field with da as 3w. Da has the edge in service and 3w usually has the edge in power. If you have never run a gas engine and do not know anything about gas engines, or do not know anyone to help you with gas engines I would buy a Da.

I just got my first gas engine, a DA-50 with a Pitts muffler. Put it in a Wild Hare Extra 300. It started right out of the box. I now have 50 flights on it and just completed using the fuel with break-in oil. It started up easily on all 50 flights and has run very well. After about 20 flights I had to lean the carb but that is all I have done. I power the ignition with a 2300 mah A123 battery pack and have had no problems. I highly recommend the DA.

In a case as described, I would recommend Zenoah. The G26, G38, G45, and G62 are all good ,reliable, user friendly, with many years of service built in, albeit heavier gas engines. I have had, or currently have Zenoah, DA, DL, 3W, CRRC, Thor, Sacks Dolmer, Brison, AM, among others, and they all will do the job, as long as you have them on the appropriate plane, and can adjust and maintain them properly. In general, I like my 3W for raw power on aerobatic planes, and my Zenoahs on the expensive heavy metal war birds. I am putting a 3W 80cc on my new giant P-47 though, over the GT 80. We are blessed with many good choices these days, IMO.

Lou, you can reduce your ignition battery to a 1100mah pack and it will still be enough for over 10 flights a day (a flight consumes roughly 60mah on a DA-50R ignition). That would save you some weight in the nose...
