RE: BME 58 Extreme
 

did the prop break
landing gear come lose or what ?

RE: BME 58 Extreme
 

I am hoping it will turn an average 23x8 above 7000+ on a stock exhaust. For that weight and power it would be awesome.

RE: BME 58 Extreme
 

yeah that would be the ticket bme is closed until 1 aug if i recall correct

RE: BME 58 Extreme
 

I liked you original number better.

RE: BME 58 Extreme
 

Hey guys, I have one of the original ten, but I won't be able to get it on a plane for at least 3-4 months. I would give it up if some one can use it before then.

RE: BME 58 Extreme
 

I'm kind of in the same boat as torqmeister. I have one of the engines but really don't have an airframe to put it on. I have a G.P. Yak with a Brillelli 54 on it that I could put it on but would rather have a 88" wing span yak for this engine. the G.P. Yak is 80" or so. I'm also thinking of getting either a G.P. Ulitmate or trying to find a Chip Hyde Double Vision for it.
Either way I won't have a lot of time the rest of this year to spend fooling with it.

RE: BME 58 Extreme
 

Will this engine balance properly in a an 88" plane? You would have to push everything as forward as possible. A pipe might be hard to do. But this is a nice problem to have. [8D]

RE: BME 58 Extreme
 

Joe I will do the EF Yak with one of the 58 if i pull the trigger on that deal and it may be tail heavy but i will still fly it that way:D

RE: BME 58 Extreme
 

there is a Chip Hyde DV in the RCU market place NIB.

RE: BME 58 Extreme
 

Someone has had to have run on of these by now?????

RE: BME 58 Extreme
 

RTK i feel ya mum is the word around those engines

RE: BME 58 Extreme
 

I have about 10 flights on mine. I have not tached it yet. It hauls my PAU 30% Edge around with ease. The power is great. The CG was not an issue. I mounted things as far forward as possible and did not have to add balast. I couldn't be happier.

RE: BME 58 Extreme
 

why,

what prop r u breaking her N on?

RE: BME 58 Extreme
 

You guys are keeping us all in suspense ... we need to see some numbers pronto.

Karol

RE: BME 58 Extreme
 

Ditto....Bump.....Nudge!

RE: BME 58 Extreme
 

no numbers yet,whats going on,well i guess it don't matter probably can't buy one yet.:D

RE: BME 58 Extreme
 

XOAR 23x8

I used to fly a Futaba 9Z and never needed a seperate tach. I haven't gotten around to getting a tach since switching radios.

RE: BME 58 Extreme
 

Guys,



I have been just moving along with the house. Out of curiosity I removed the 23A Vess to try RPM wise a BME 24 x 8 prop. I re-tacked the 23A and it was over 7500 RPM with less than ½ gallon on the motor so I think on up lines I am screaming more RPM than I really need to be. The up lines are very fast with the 23A. I did not fly the 24 x 8 BME prop. Here are the vid I just did on that deal. I have to let my radio fly around on my neck strap to be able to hold both the camera and tach is why it’s sloppy. I know some of you could care less about RPM. This Vid is to help me confirm to go to a bigger prop to bring the RPM down along with seeing how I like the way this prop handles the Yak. I am feeling like with that big nose getting more air past it could only be better. If anyone has any input on different brands of 24" prop please share them as I do not have any other 24" props to try but i do have plenty of 22" props which is what my Brison loves.

Set up is BME 58

11” Carl from Canada 1” header

ES Carbon Fiber Pipe

EF Yak 54

RE: BME 58 Extreme
 

I had a chance to run my 58 today. It is set up with a stock muffler, which is the same as the 115, but with the exhaust flange moved. The engine came very rich so I had to lean it quite a bit. When all was said and done it would turn a menz-s 23x8 at 7200 rpm. Total run time was about 10 minutes. The engine does not seem to vibrate at idle very much, and throttle response is linear and smooth.
Now I have to move my batteries from behind my canopy to the motor box.

RE: BME 58 Extreme
 

I put in six or so flights today on my 58. The first thing I can say is that my EF Yak finally flies well. It is amazing how much better a plane can fly when it is 2+lbs lighter. Everyone raved about that Yak, and to tell you at 19lbs it is not that good, but get it below 17 and it is a much different plane when it comes to 3D.

First off, I don't baby any of my engines. My break in, is to set the needles to proper running and fly it like you would any other plane. I beat the crap out of it today. Lots of WOT and hoovering, (not that I can hover all that long, maybe 1 minute) not recommend on a new engine, try at your own risk.
I just about have the needles to where I like them. The low will take a few more flights to make perfect, but I am in no hurry because it is really nice where it is anyway.
So, if this engine will last the test of time, (which I have no doubt) It's a winner.
Now it is time to pipe it and have unrealistic power.

RE: BME 58 Extreme
 

If only I could coerce BME Tom into sendng me the parts to straighten out my 115...........

I'd be happy to send them whatever they charged but I first need to know they will actually ship something. Too many broken BME promises for me to trust anymore. They've been sitting on Altavillan's reed block paid for since last April.

RE: BME 58 Extreme
 

I was sposed to fly with Ralph tomorrow but nooo! he couldn't wait and went out and played today! Now he has to do honey doo's tomorrow. I'll pen him down eventualy.

RE: BME 58 Extreme
 

What can I say, I was like a kid with a new toy:D Don't worry, as soon as I get my header parts I'll let you make me a bud cannister:)

RE: BME 58 Extreme
 

RTK,

What was your set up to drop 2 lbs? Mine weighted in at 17 lbs 4 or 6 oz with a Brison 3.2. Of course I have pulled the Brison off and will put it back on a DP EXtra. I have not weighted the plane with the motor swap out. I know the BME is suppose to be lighter but I am not sure by how much. I shifted my battery to the firewall and I am back natural on inverted flying now. I love the fact that a 24 x 8 prop spins very easily with this motor.

Tired Old Man what parts are you waiting on? I just installed my Reed block on my BME 111 (a 115 bottom end on 100 jugs). I did not fly it but it ran well on the ground. I took the time to set it back up with a throttle servo move so I had to re do my throttle mix. I spin a 26 x 10 Mejzlik at 6900-7k. I will be looking at trying a Vess on it soon as I start back flying it more. I think I have about 3-5 gallons on it. I never had any issues that the 115 guys experience but I still rated the block so I sent it for it as one day I may pull my 100 jugs and pistons off to put on the 115/16 parts.

I worked in the garage all day on my birds that have had their share of sitting this year and things came together pretty well. I think I will be looking to take out my Extra and Ultimate tomorrow as I will call this big bird day of flying .

RE: BME 58 Extreme
 

krayzc I had a g62 on a pipe in it. The 58 weighs 3lbs1oz with muffler, the 62 with header/pipe weighs 5lbs+. The plane came in at 19lbs with the old configuration, so now I should be just below 17. It sure made a world of difference in how it flies.
