Hello. I would like information/opinions and or experience with BME engines. Preferably the 105 but any will do. I am considering the 105 for the Hangar 9 Edge.

Thank you in advance,

Robert

BME makes good engines. Some of the bigger ones run a little warmer than their cousins, but they are made lighter. Baffles will cure the heat issue should it arise.

No, I don't run BME, I use another manufacturer, but I personally know others that do and they are quite pleased with them.

I had a used 44 and liked it. Ran good and was strong on the plane I was flying. Sold it. Good luck with your project.

I'm currently using 3 BME's, a 50cc and 2 44cc. No complaints with any of them! I'm sure someone can help you with the 105cc and 110cc engines.

Ripper;
I own a 44, 102, 105 and a 110.
All have proven excellent. I have seen people burn the cylinder walls by not breaking them in properly and not providing ample airflow. These people did not listen to suggestions. A friend has the 540 with BME105, What a combination! You will be very pleased with this match and 1.5lbs lighter than other twins this size and that will translate into a better flying plane.

BME 44 my first gas on my first giant plane: hard to idle from the very beginning, carb leaking fuel. ( I have seen couple of post about this prblem on BME44). Engine quit on me several times, last time it did, I lost my Carden 27% Extra.

Possible explanations: bad luck, also I may got a deffective carburetor, go figure...

If I have time, this winter I may be running this engine in the test stand to troubelshoot the leaking carburator and the idle, any suggestions to fix this?

Albatross-Send it back in for repair. All manufactures will warrenty defective parts. If it came with a bad carb it should be replaced by the manufacture.

I have the 110 in a H9 Sukhoi. The engine performs flawlessly.

I've had a BME 102, a pair of 105s, and now have a pair of 110s. I've been VERY satisfied with both the engines and the service.

I have had a 50 and now the 110, nothing but praise for both, especially my 110 which is noticibly more powerfull than either DA 100 or 3W 106s I have had.

How's their turnaround time on engine repairs?

I have a BME 102 and I can usually get the engine to fire on the first flip. If not, then it is flooded and it takes 5. It runs with no issues and is very strong. I have not had to deal with the service department yet but I hear that they are good at what they do.

If you call 400rpms less than my 106 on my 28x10 noticable more powerful you must be smoking something. Your motor did run very well but it should on a 21lb airframe. I think you need a little more time on a suitable plane before you can make a fair compairison. 6100rpms on a menz 28x10 is a fair number but nothing special for your 110.

We have come to conclusions that rpms on the ground mean nothing, but how it sounds in the air, and the 106 wouldnt rip the prop as loud as the bme, just the facts ! Doesnt matter anyway, power to weight the 110 has no equal.

Spindoc- not to be argumentative but, I have seen a couple hundred rpm difference with 2 props from the same manufacture same day same engine same time.
There are many variables-temp, humidity, elevation, tuning, etc. when trying to compare RPM numbers.
I have not run my BME 110 on a 28x10 yet, but I feel I can match the 3W 106. Oh and by the way I am waaaay lighter too.

Ralph,

You must have finally gotten the move complete and the field work has slowed down a bit. You activity level here has gone up a bit.

Glad to see that you are finally getting a little time for yourself. Hope you're doing well.

Thanks, by the time I ran the engine the warranty was already due. [&o]

It was the same prop swapped from one motor to the other so the different prop theory does not apply. I'll restate that the 110 did run very well on a 21lb airplane, and it should.

6100 rpm can't be right. My 110 is running way strronger. How new is it?
Was 6100 peak rpm? I turned more than that on my first run with my 110.
My last flight I was turning 6450 rpm. I am still breaking it in with lawnboy. Stock mufflers.
Try tweaking those needles a little. 1/8 turn can make a big difference.

The motor had 3.5 gallons through it, lawnboy 32:1, and the top end not peaked being new.

That 21 lb. plane must have been a rocket or at least it would be here at sea level.

I have a BME 102 that turns a 26x10NX 6000rpm.
I installed a 3W intake manifold and the rpm went down to 5750rpm.
I noticed in the air the propeller was louder. I can only assume that I am not getting any blow by in the intake and all the fuel is going into the engine. I think I need to lean it a little or it was too lean before. It didn't run hot and never had a problem! Engine is still tight compared to a couple of others that I have flipped. Does this mean that it is not broken all the way in yet?

I have a BME 100 and a 105. Both engines run great, and as stated above, there are simply no other engines with the power/weight of a BME twin. My 100 is well broken in and turns a 26-10 NX at 6400. I tached my 105 when it was brand new and it turned a 26-10 menz S at 6700. It now has a couple of gallons through it and it is a powerhouse. You can't go wrong with BME.

Gentlemen, this is a great thread. Thank you for all your replies. It takes the stress out of buying an expensive engine that I know nothing about.

Thanks again.

I have 400 flights on my engine.
How many on yours?
