It looks like the BME 110 is 3.9 lbs for 10.5 HP whereas the DA 100 proports 9.8Hp at 5.8lbs. It looks like the BME is better performer. Anyone run both of these on similar planes before?

I have run both. Both great performers, with the BME 110 have a little more power on top than my DA. The BME can be tricky to get a plane to balance with it, depending on the airframe you chose for it. I am right up the road from you in Temple. PS, dont pay too much attention to claimed HP numbers, they are not very accurate for our application.

Unfortunately, I can't say the same. Side-by-side, I ran my 110 with a 26X10 menz for a MAX RPM (the highest R's the engine has ever seen on the ground) of 6400. This was the first run of the day for me. I then walked 10 feet over to my buddy's plane, whic has a DA 100 on it and a Mejz 28X10. It was also his forst run up of the day, and I tached 6400 with the same tach. It was an embarassing experience[]
I can tell you that I did personally see one run prior to buying one and it seemed like quite a powerhouse, which is why I decided to purchase one.
I haven't given up on it yet, but I am very disappointed in the lack of power, especially since I get a badgering from all the DA lovers here! I love DA's, too, but my elevation (6500) convinced me to try the lighter engine. I hope that, in the long run, this thing does finally come alive so I can actually manage to get my 25.5 pound plane to climb out of a hover!

Wow, all I have for a 26 pound plane is a Brison 105 and there are far too many people to attest that it will pull that Giles straight up (while accelerating all the way) out of anything on even a very hot day (110 plus) at a field elevation of 1,400' msl. With a 28-10 Biela BTW. OTOH, a friends 110 beats my 105 into the dirt, so perhaps it's not the engine?[8D]

3d-aholic--Don't get hung up on HP numbers, they really do not mean much. (as stated before) Now if the manufacturers would give you torque/hp curves you would have something.

The 110 should spin about 100-300 better than the 100 from what I have seen and read. (both are good engines and you can't go wrong with either) Also the 110 is no longer manufactured, it has been replaced with the 115. The new 115 is "supposed" to turn about 100+ better than the 110, we will see. Not that it means anything, but my 110 will spin a mejz 28x10 at 6500 static on stock mufflers.

Silversurfer,,Was that comment about "beat it into the dirt" about the power of my 110 compared to your 105, or the fact that I did beat my plane into the dirt the last time we flew

The power, not the gardening

You guys have this on the WildHare Giles? Whats the best engine combo for the New WildHare Edge?

I can't give you the "best" because that's subjective and user determined. I would consider a very strong 80cc to 115cc twin for the plane. The lightest and most reliable will be the winner every time. At 5.5 pounds my Brison is on the heavy side and anything heavier would be worse. That includes DA and 3W. A ZDZ 80, possibly a Kroma 100, and the BME 115 when it's released ( which should be very shortly) would be my first 3 choices. The final decision would be based on what it might be needed for later.

Mstroh curently has the only flying big Edge, so he might be a good person to get in touch with via a PM through the W/H forum.
