Well Jordster I would like to see it. These day car engines are made for just that job. The have built in starters and much better cooling. Back in my dads day the Boat, Car and Plane motors differed little. This would make a great FAN car. Please just be careful with the prop. FIT A GUARD.

Hello, my friend. No. Only Airplane

 Allison 1357 points

So Lilkrazy the answer is NO. This is a engine that it meant to swing a PROP (weather that is on a Plane or Air Boat or a Monster Fan Truck).

 henrique899 9 points

Hello, my friend. Only Airplane Propeller 10x6,5 or 11x5

 Allison 1357 points

Well it does say in the listing ""This high torque glow engine can swing a 11x5 prop on standard 0% nitro mix."" but I though most 46's swing a 11 inch prop. I have seen one with a 9 x 7 or 9 x 6. It was in a smaller sporty plane.

 Kellyann 16226 points

Adiboy no but very cool idea. I did have a small AIR glow boat. The only mistake I mad was not to point the motor forward (I pointed it rearwards) Hence it got very hot. If I had pointed it forward the air flow would have keep it cooler. What do you think.

Hello, my frined. No. Only Airplane

 Allison 1357 points

Why this engine will work fine as long as you fit a prop to it. SO FAN BOAT, FAN CAR or PLANE. Please remember safety safety safety safety. You cannot buy fingers anywhere!!

I think I figured out why some seem to run awesome, and some destroy themselves after little use. It's a quality control issue with the carb. I've had two, one wrecked the liner fit after two flights, the other is great. I finally dissassembled them completely to find out. On the one that works good, the spray bar on the carb points down into the engine. On the one that trashed the liner early, the spray bar points directly up out of the engine. So if you get or have one of these, make sure you can't see the little slit in the little brass tube you can see when you look down the intake, otherwise it's wrong! What happens is you can tune the high end right, and you can tune the low end right, but the mid range is lean. Lots of flying happens at mid range, so this quicly overheats and wears it out.

 meatshield 16 points

To fix, remove the little screw on the intake side of the carb, then you can slide the barrel out sideways. There's a brass tube that's left sticking into the carb throat. Remove the needle, and !important! unscrew the needle holder from the carb body and remove the gasket. Then you can gently tap the brass tube out from the carb barrel hole on the right side of the carb. Then insert the brass bit back in, in the correct orientation, and push it back in. Give it a tap to seat it. Reassemble and continue with break in. If your engine has been running good for some time, you don't need to worry.

 Allison 1357 points

Like wow. So is it just assembled wrong or what. Good fix and thank. Great to know

 meatshield 16 points

yup, just assembled wrong. Easy fix, but by the time I'd figured it out, the mid range had leaned enough to wreck the liner and I needed a new liner/piston. But that's another easy fix if you can find the parts.

 Allison 1357 points

So this is a great little FIX. You need to save you instructions in a Word Doc call Ideal fix and post it under the "File" section. Then in months to come when others have the same problem (and they will) we can find it.

 Youssef 191 points

both are in the same size. but os engine another brand

 Javier 1 points

Its basically the same size. I beleive LEO is a liitle heavier compared to an OS same size.
Very important the break in process. Make at least 5 or 6 tanks before the first flight.

 Allison 1357 points

So NO Jean. You can not compare a OS to a LEO. It is like comparing a Hyundia to a BMW. The both make a 2 liter engine but far different. The LEO is a ABC engine where the OS is all matched. Well the piston and liner is.

 Bellakelpie 63 points

The Leo Piston and Liner are a perfect drop in replacement if you need to rebuild the AAC version of the OS SF.46. And the Leo Liner is Chromed Brass, unlike the OS's Chromed Aluminium. The OS 4d carby that came with the SF is superior in quality to the Leo Carby.

precisa de glow plug, nistarter tanque de combustivel.

 Allison 1357 points

Ashwin Please understand this is NOT electric motor. This is a fuel engine. It is powerful and messy. I you wish a electric motor have a look at Brushless Motors at this web site. PLEASE

 ashwin 36 points

I'm well aware that this is NOT electric and that this uses nitro fuel. I want to know what else I should buy to make this work

 Devz_irl 23 points

Of course 5pcntmin nitro fuel,you will need a glow plug (not on hobbyking)as they do not come with one,Engine mounts for your model,Fuel tank and fuel line.For this engine a propeller size of 10x6.To start it a glow driver and a chicken stick or battery powered spinner.

 Kellyann 16226 points

Sir for most things a 4 stroke engine give more torque than a 2 stroke. But with aircraft engines RPM is most important. Hence a 2 stroke for the same cc will swing a bigger prop faster. So it is 2 stroke OK I hope this helps

 Thomas 16 points

2 stroke engines

 F100CUFFLINK 886 points

4 stroke has moe power but less RPM AND SOUNDS MORE REALISTIC .

 Eduardo 5 points

comprei o motor e demorou para chegar devido a greve que estava no brasil, ao chegar ao amaciar no terceiro tanque quebrou a biela e perdi o motor, agora nao encontro onde comprar as peças de reposição.

 Mike 3 points

Yes should be fine test it before you do any crazy 3D with it. Prop selection will make a huge difference

 Balazs 4 points

Thank you for reply! :)

 boingk 257 points

I do not think this would be good for a 3D aircraft weighing 2500g - it would only give you about 1200g of thrust with a 10x7 or 11x6 prop. If you mean will it make for a good aerobatic plane, then yes, but not full hovering & vertical climbing 3D. Try to keep overall weight in the 900~1000g range for full 3D... hard to do with smaller glow planes!

 Rothmans 1377 points

Balazs, had you test this engine is it capable for 3D flying? What plane are you install for this engine.

 viana 25 points

so passei raiva com este motor nã*o recomendo.

 Hugo Antonio 2 points

advised not to do this, this type of mixture carbonize the engine Too I do not have a good yield, the better are the appropriate fuel.
recommend for this engine 10pcnt nitro 18pcnt oil

 noclassmac1972 44 points

As with most abc engines you can run 15% oil and if you wish 0% nitro but you need to take a shim out of the head , at present I am running 5% nitro just for consistancey and ease of needle setting. Works well.. Remember if the F2A boys can do 190mph on no nitro we can go a lot slower

 Vicon 4 points

Hi, can You tell me what is basic substance in the mixture?. X% oil, X%nitro into what? BR. Vicon

 Kellyann 16226 points

Sir I like you thinking. When I started in this I use to mix all my own fuel. All the advice above is good. Some a bit hard. Just make sure you measure carefully. Do not mix to much at once. The fuel start to age as so as you mix it. Above all things have fun and try different things. Also let us know what results you have. Just remember do not run to hot or to lean. The oil is in the fuel MMM. I hope this helps

 Adriano 14 points

I'm flying over a month with homemade fuel, using methanol and 16% castor oil. Engine works very well, of course a bit of work but after the adjustments is only joy. My tip to whether or not using nitrous is: Use candle to A3 rich mixture to avoid burning.

 gibbo1 11 points

mate number 8 is the most common one used

 Adriano 14 points

The number 8 has a better idle and longer life. You can use the number 3 but will change more often.

 Hugo Antonio 2 points

number 8.

 Polardegos 54 points

What does this mean? Number 8? Number 8 what? Is that a specific brand of plugs, or is it a common way of telling plugs apart?

 leandro 21 points

no, this engine is the engine model airplane,engine heli you will find in section glow along with this.

 hm138 24 points

I can't give you any figures but I have this engine on a Seagull Boomerang trainer and the fuel consumption is surprisingly good. Hamid

 leandro 21 points

hello, I have this motor with a normal tank and it can fly 10 to 15 minutes, and it need not be regulated because they're in the range allowed for flights, not only for flights which have public, as well as squares and etc. ..

 Hugo Antonio 2 points

o motor pode esta carbonizado dependendo da mistura de conbustivel que usa.fassa a regulagen do motor novamente.

 Eduardo 5 points

Comprei segundo indicacoes de o motor ser muito bom, o meu naoi chegou ainda, apos chegar posto o resultado..

Hello David, I have 2 of these engines running with 11x6 propeller without problem, with these propeler they will stay more stronger and with less speed.

no trouble at all men, its a good size for engine

 RC Fun 371 points

I am told a OS will fit but they cost nearly the same as a complete engen from HC so I went for a whole new motor

 siqueira753 24 points

estou aguardando o meu mas ouvi dizer que e bom

 Olderflier72 5 points

what problem are you having with LEO carb. i just put one in my model and had very little trouble getting it runing.it had to be very wet to start and i had to use ele. starter, something i do not like to do. once started at a rich setting, i then began to lean it out staying on the rich side. i ran it 3 times for about 5 to 8 min. cooling down down for a short between runs. i run it the first 2 with a 10 x7 zinger with is kind of a wide prop, then changed to a topflight 10 x6, wich is a narrowe

 marcao cantor 14 points

good you can use a spine which either 2.25 or 2.50 this is a very good and very beautiful and guaranteed

 Miguel 2 points

propeller: 10X6 10X7 or 11X6 after fine tuning you can easy start it manually but be careful with your hands because this engine kicks really good. suggestion: use gloves. sugesttion 2: fix the prop till the end wen the engine starts to break with the prop in vertical.

 Henry 1 points

this is very good engine brake in so easy

 Olderflier72 5 points

on hard starting eng. i have,and it seems a little strange to some of my other flyers, that if you flip the prop backwards the eng. will crank quite easily. sometimes if it is to rich it willrun backwards but you can hit the front of the spiner with you hand and it will correct itself of die. i have did for years on 60 and 90 size eng. and you don't get your hit.

very good engine! I'm building my first SPAD, a scale. A Cub of 1.9m wing span ..... I was going to buy a G60 Electric but finally ordered a .46 LEO ! I have already another One ! Seems to be a very good engine !

Yes thanks I am normnally electric man myself but I suppose sometimes you have to have Noise with beauty dont you????

Do not open the engine to be sure, but it seems to be rolling, and works great!

 Basstronics2 90 points

Wow thats not even worth posting. The dang thing better turn over and work- its new. I just wanted to know if it has ball bearings or not before I order- or not.

 Olderflier72 5 points

normaly when the area right behind the shaft entrance is larger than the rest of the case it means that it has a front bearing also.

allen

 F100CUFFLINK 886 points

this is a ball bearing engine but for few bucks more i would get the ASP much better engine , the leo is a remake of the ROYAL engine from 20 years ago and they were not very well built, so to play it safe i would get the asp .52 much much better

 Miguel 2 points

it´s ball bearing, very durable and easy to work. i got one. very nice engine for the price

 HobbyKing_Admin 8862 points

Cufflink, 20yrs ago I was flying with a Leo28. I dont think they are remakes. Where did you read that?

 Turbobeaver 1336 points

The Leo engine is not and never has been a remake of a Royal engine.Royal was a trade mark name of a hobby distribution company originally in the US(Colarado).They had RC gear manufactured with their name and logo on it.Some engines came from the Leo plant and some engines such as the Royal .45,came from the Thunder Tiger plant.The Royal.45 was identical to the Magnum .45 produced by Thunder Tiger with exception to their logos.The parts were totally interchangeable.

shaft dia. is 6 mm, any large spinner for glow engine will suit

 00554236351088 31 points

The shaft diameter is identical to any other engine of equal size (.40 to .50). Use a 11X6 prop and will be perfect, use helice 10x7 and be fast. The spinner is ideal (Nylon Spinner 2.25inch www.link

 Miguel 2 points

diameter is 6mm. any normal spinner for that engine size(.46) will work just fine.

 Olderflier72 5 points

about spinners,the size of the spinner is according to what the modeler wants. the center area of the prop has no pull. the largeness of the spinner does not have a lot to do with anything. you know when it's to big, it looks ****y on the model. if the nose of the modelis shaped you want the spinner to look right. the smallness is decided by the prop. as long as the spinner does not touch the prop on either side it is ok. if you need a smaller spinner you can trim a little off the spinner to cle

 maurortiz 2 points

wayfive,,, you need a 11x5 prop, and the diammeter is 7mm

 F100CUFFLINK 886 points

What the heck are you talking about you guys ?
you need what ever spinner the plane calls for ,why are you saying 2 1/2"

 Aleksandr 6 points

for a start through a starter, aluminium or plastic spinner is needed. And for a start a hand, spinner unnecessarily.

 celio 6 points

coloca uma helice 10x7 fica um canhão.

 Miguel 2 points

you don't have to buy aluminum, it can be plastic.usually the spinner measures are for the motor sizes ,so just by one for .46 motors .

 Henry 1 points

better don use aluminium.

 Sheko 140 points

i faced lots of problem with the low end neadle
i turned it 1/4 turn clock wise

 RCGraeme 7 points

I have been running in my Leo 46 and cannot believe it run 1st time. Factory idle mixture. Wound out needle 2.5 turns, fuelled up and it started first time. I have run it 3 times now and have just had it up to full speed and turned the needle back 1 turn. ie, 1.5 turns out. The venturi is almost shut and not as wide as I would have thought. I think is an OS46FX copy so I used that engine manual. Good luck.

 Willie 6 points

Try using a 10 X7 or a 10 X 8 prop, set the needle valve as per the instructions on the engine manual
