DA-100, BME 115, 3W 106?

[Izzy]

Hey guys, I just wanted to see what you all had to say from experience about these engines. I'm planning on building a 100CC plane and keep it as light as possible. From the specs, the BME 115 has the most amount of power for the least amount of weight, more than the specs of a DA-85. I would rather have a twin cylinder, but might go with a DA-85 for weight's sake.

I'm planning on building a CompARF 2.6m extra or 2.6m yak. It looks like the DA-85 would be perfect for it, but the BME 115 is a twin.

Any experience with these engines? I know that DA has incredible service and that 3W engines are very powerful, but I don't knot much about BME's service/reliability/etc.

Any help is appreciated!

Cheers,
Izzy

Let's please keep this to experience, as I'm not trying to start a brand battle

all of those are motors that i would consider but if weight is a concern you must pick in that order....

My experiences:

DA-100: Powerful, reliable, excellent service, but I've seen a lot of them need service after 300 or so flights.

3W106: VERY powerful (way more than DA). Very reliable as well. Excellent service as well through www.AircraftInternational.com. Mine has about 240 flights and going strong.

BME: A friend of mine had a 110 and yes it was light, but he needed a lot of nose weight to balance on an H9 Extra, which is a smaller lighter plane. It definitely is not as powerful as they hype it up to be. Gave nothing but problems and he could never figure it out. He then changed to another brand engine.

Again, those are just MY experiences. I would go with the 3W HANDS DOWN. Good luck.

If there was such a thing, that 2.6 would be WAY overpowered with the 115! But since there is no such thing as too much power...
I have experience with their 110 and their service. The engine never died on me in the air, but it was not the powerhouse that it was hyped up to be - at least not to me. Kieth has excellent customer service, though.
If you want light, the BME 115 is the answer.

My experience.....

DA is just a out of the box power house (especially if you do not like fusing with engines).
3W just keep getting stonger the longer you run it (will last a long time).
BME runs great, quite and light. However I do not believe it has as much power (personnel opinion).
Do not know about the 85. I hear is low on viberation and light....
You will probable be happy any of these choices, but if you need a light engine, the BME might be your best choice.

I agree with the power hype of the BME. My 106 will out pull it any day and yes I did have both. The main thing is I never worry about my 3W flaming out. Keith does have a new carb coming for the 115 so maybe that will help.

everybody really told it like it is-good advice

You mean your BME flaming out?

I have the 115 and it is a power house. The 110 and original 115 were a little tricky to tune, but once you knew what you were doing they ran super. I have also had good luck with 3W. Never owned a DA.
Service is good from all. But power rankings would be 115, 106 then 100.
It really isn't hard to balance that plane with a 115, you should not have to add any extra weight.
When it comes to reliability I think they all are about the same. You will more than likely crash your plane before you wear any of them out.

I'd go with DA or 3W just for reliability.

On my 110 I once turned a 27x10 prop into a 10x10 prop, when I collapsed a gear, sent it in because I was sure I twisted the crank, got it back in 7 business days and Keith said no damage was done all was still straight.

I think it's between the DA-85 and the BME 115. If I can keep the plane at or below 24 lbs it will have balls to the walls power and float around like a foamy. I hope Keith at BME has come out with the new carbs for the BME. I heard he has great service, and even if it puts out the same power as a DA100 it's almost 2 lbs lighter and you can't go wrong with that. If the DA-85 doesn't shake too much it will also be a pretty good choice to keep the weight down and power up. I can only imagine what a 24 lb plane will look like with an engine that puts out close to 60 lbs of thrust lol
