The new BME 150LT in a 35% plane? You betcha!
I started this post on the other major RC website. I'll start it here too because it's interesting and fun. Let's have some fun!
While I won't be the first person to grossly over-power a plane, I might be the first to put the new BME 150LT in a 35% plane. The 150 will replace my nearly new DA 100 in my WildHAre 35% Extra. The Extra is an awesome plane with the DA 100 in it. It weighs in at 28 pounds even. After the engine swap, the weight will be nearly the same as the BME 150LT is a within a few ounces of the DA 100. I thought this combo would be a no-brainer. IMO, the 35%WildHare Extra is the perfect plane for this engine swap. At 28 pounds, the weight is good for the 100, and should be unreal with the 150. This plane is BIG and long. The beefy engine mount of the Extra will handle the 150 with ease. The plane and landing gear is plenty tall enough to handle a larger prop. Tom at BME said the BME 150 will run great on the big bladed 30" props like the Mejelik and MSC. So, call me a fool, or say what the hey, lets see how it does.
Are you interested?

RE: The new BME 150LT in a 35% plane? You betcha!
I will compare the BME 150LT to the DA 100 just for comparison's sake; to get a feel for the size difference for the swap.
The weight of each engine is similar. The entire setup for the BME 150 came in at 7 pounds, 8 ounces. That's the engine, mufflers, ignition, plugs, and bolts.
The weight of the DA 100 setup is 7 pounds even. That's an only an 8 ounce difference.
The overall measurements are similar. The mounting pattern of the BME is about 1/4" wider. Both engines are a bit over 6.5" hub to backplate. The BME is about a half inch narrower than the DA 100. Mufflers from both are about the same size. The exhaust opening of the 150 muffs is much larger than the 100, as it should be. Looking at the pictures in the next post, you'd think the BME is larger, but it's not. It just "fills up the area" of the overall dimensions more.

RE: The new BME 150LT in a 35% plane? You betcha!
I am a little surprised with the weight of the BME 150. The BME website gives a weight of 5.58 pounds for the engine. I am going to assume the mufflers are 10-12 ounces and the ignition is about 6-7 ounces, which means the engine must weight close to 6.5 pounds and not the 5.58 pounds shown at their website.
BTW, this should be very interesting. It would be nice if someone developed a 31-32 pound ARF for this engine with wing area of about 2300-2400 sq inches

Almost every single engine manf weighs the motor with "Nothing" attached...at least BME throws in the prop bolts and prop washer. But i can't think of another engine Manf that adds in mufflers , ign and so forth. Either way...the BME 150 will come in a good 2 - 2.5lbs lighter than any other 150 on the market...and that a lot of weight when it's strapped to front of an airplane. It also takes up the same amount of room as a DA-100. It also weighs less than a 3W-106 , or new 110 as well.....with way more power.

I do know that my RTF 35% WildHare Extra with the BME 150LT is 27 pounds, 5 ounces.

It is quite likely that existing designs in the 40% area might have issues balancing with an engine that is two pounds lighter in the nose area.
I couldn't help but notice the comparison is done with the old DA-100. The DA-100L Brings the overall weight down by some 6.6 oz.. Nevertheless, the dimension and weight of this BME are impressive...

For break-in I have a 30" Mejelik. There is 5.75" of ground clearance with the plane on all 3 wheels. So, I guess it would be 4.75" with a 32" prop. Should be enough for me.

RE: The new BME 150LT in a 35% plane? You betcha!
Marzo....when do you plan on doing the maiden? Over on the other site , a guy that tests BME's mentioned that he thought the Mej 28.5 X 12 3 Blade was to much load for the motor , a 32" 2 blade might well be to much as well. Over on the Mejzlik website they list a 27"X 12 TH 3 blade that think would work great though. And for the 2 blades he mentioned just sticking with a 30". I'm curious to see how your 35% bird will slow down for landings and so forth. can't wait for a report from ya!

RE: The new BME 150LT in a 35% plane? You betcha!
I took the BME to the field today. The engine started right up as soon as the fuel hit the carb. It needed to be leaned a couple screwdrivers widths so it didn't stumble. I didn't optimize needle settings yet. I only had an hour, so all I did is run it for 5 minutes and get in two quick flights. I didn't really get on it too hard at all. As we all know the power will be/is unreal in this plane. Point the plane skyward and 1/3rd throttle will pull it like my DA 100 did WOT. Go to half then full-throttle and it looks like a rocket. The plane turns into a tiny speck in about 3 seconds.
The plane flies, handles, and lands just like it did before, except for what "seems" like twice the power. This engine/plane has no nitrous, but it sure looks like it does.

That is simply friggin' awesome! Gives more and more hope for my next build. I always wanted a pathetically over powered airplane HAHA!!

Some of the WildHare planes come with 2 wingtube locations. A nice feature to help balance the plane. Big single engines use the back position. Twins can use the front. Pretty neat,huh?

When i designed the plane using the BME-115 was an option, also a DA-85 or ZDZ-80. It can be a problem trying to balance a plane with these super lightweight engines, so I added a second wing location.

Hi Marzo91,
Any update on BME 150LT? Any reliabilityissue?I am considering it for my Composite ARF Corsair.
Thanks.

I've been flying the new 58 Extreme quite a bit too. Both engines are excellent.

While I won't be the first person to grossly over-power a plane, I might be the first to put the new BME 150LT in a 35% plane. The 150 will replace my nearly new DA 100 in my WildHAre 35% Extra. The Extra is an awesome plane with the DA 100 in it. It weighs in at 28 pounds even. After the engine swap, the weight will be nearly the same as the BME 150LT is a within a few ounces of the DA 100. I thought this combo would be a no-brainer. IMO, the 35%WildHare Extra is the perfect plane for this engine swap. At 28 pounds, the weight is good for the 100, and should be unreal with the 150. This plane is BIG and long. The beefy engine mount of the Extra will handle the 150 with ease. The plane and landing gear is plenty tall enough to handle a larger prop. Tom at BME said the BME 150 will run great on the big bladed 30'' props like the Mejelik and MSC. So, call me a fool, or say what the hey, lets see how it does.
Are you interested?

I am very interested, I just ordered the 35% Russian Thunder scheme Yak 54 and I've got a 3W106CS but the idea of a 150 at almost the same weight is intriguing.
