Either will work but I also use 10% with this engine. I also use a small amount of castor oil in the fuel particularly when the engine is new. My standard fuel mix is 10% nitro, 5% castor oil, 15% synthetic oil and 70% methanol. We have found that these engines also run perfectly without muffler pressure. Just take the vent line from the tank to a place where it will not be in a negative air pressure area. A good solution is to run it along the side of the engine mount so it points forward into the prop.
Hi all I have a question, I just got a phoenix model Sukhoi SU-31 flying weight of around 6 lbs or 2800 kg, recommended engine 46 two stroke or 52 four stroke. Should i install an ASP 61 four stroke or an ASP 91 four stroke? I'm looking for good aerobatic and 3D capabilities. Thanks.
for aerobatic, a asp 70 would be best for 46 replacement. asp 91 would give you more power, but you have to be careful about the weight, you might be nose heavy, then if you need to add ballast at the back, its a dead weight.
hello I have a corsair of phoenixmodel the rebound 46-55 or 52-70 4-stroke engine recommended, its weight is 2800kg to 3200kg and seen who speak well of obio asp is not you but as you say price relationship, my question is the privateer carries much weight in the nose to bring it to the point where the center of gravity would combeniente put a 91 4-stroke engine, the other question is I use 3 blade propeller and being so serious tronpudo combeniente prop used to measure for this 61 asp 4 stroke.
waiting for your reply if anyone has used this plane I could tell the less the weight carried in the nose.
I await your response thanks a great greetings
pd: sorry my English is not very good
I'd use a .61 with a 12x7 2-blade propellor to start with. The .91 will be too heavy and also use more fuel and need a larger mount - I would not use it. The ASP engines run well, you should have no problems with them. If you *must* have a three blade prop then try 11x6.
Hi everybody, I just ordered the B-25 from Hangar9 wingspan 2050mm it has a flying weight of 13.5–*15.5 lb (6.1 kg–*7.0 kg), and i was wondering if two of these would be enough? and if yes, what kind of 3 bladed propeller would you use?
thank you very much
I have this engine in my hangar 9 p-51 and it's great. It has just the right amount a power and seems to be very reliable. For the price I don't think it can be beat.
Oi Daniela. Vai até* sobrar potê*ncia. O 61-4tempos equivale ao 46-2tempos, e vc vai inclusive poder fazer umas manobras mais folgadas. Mas se vc quiser fazer um vô*o mais escala, considere dois 52 ou 56 4tempos. Abcs!
I'm sorry my english is not very good, so I want to ask I do not understand I have a phoenix tukano 46-55. Which do you think would be appropriate to the ASP engine 61 0r 91( four stroke)
I have two PC9s and a Tucano, all three in the same class 46-61, I have flown them on SC52fs and found them slightly underpowered, depends on your comfort zone, anyway i now have ASP61s in them and find the combination ideal. It is a matter of personal choice, and don't forget, prop size can also make a big differance. I would not say you need a 61 two stroke or a 91 four stroke, probably a little too much if you are fairly new to the hobby. If you decide to stick with the engines you have mentioned the 61 two stroke will probably give you more air speed. THe choice is yours.
Omer are you asking is the engine, a 91 (0.91ci) or a 61 (0.61ci). This is a 61 (4 stroke). I does say from 9.95cc which is about 0.61ci. Also the product name also helps. ASP FS61AR Four Stroke Glow Engine. It is a easy to get it confused. We name most engine after cubic inches. Yet displacement here is in Cubic Centre Meters! Good Flying
Hi Good Life, Yes the carb is at the back of the engine and , it has 2 needle valve high speed and low speed , this could be fun to use a 4 stroke , good luck , have a nice flight for storage pleas dont keep the engine dry it might get rusted inside
Hi all i have a question, i've recently bought a graupner scale cessna 172 1,7 wingspan, the recommended engines are os46 ax or os fs52, but club mates told me that this engines won't pull very well the plane cause it weights 3,5 kg, i'm looking for an asp 4stroke but a 61 is not enough and 91 seems too big (the os 46 and 52 weight around 500g, and the asp fs 91 640 g) what will you do?? i hope the asp fs91 fits well maybe . TY all
If the recommended engine for your plane is a FS52 - then the FS61AR would work very well indeed.
It packs a lot more punch than the FS52 and weighs less that a FS52.
It should be more than powerful enough to use in the 1.7m Cessna.
The FS61 develops 15pcnt more power than the FS52. If a FS52 is recommended then the FS61 will do the job. I you want a bigger power margin then use the ASP FS70ASR. I have used the FS61 in a 72" Thunder Tiger TT60 with out problems.
Hi lilkrazy,
This 4-stroke engine is for airplane use only. Not fit for Rc cars or buggies. I suggest you to buy EG Race 25 Two Stroke Glow Engine (PRODUCT ID: 22000013)
Hi fqahmad.
I have been flying with ASP Four Stroke Motors for years. I have been using a 5pcnt Nitro, 20pcnt Castor Methanol mix.
Glow Plugs - I use OS Type F or ASP Dual Plug - depending on what is available.
If you have not yet ran your FS61AR in - you should be able to run it on a straight 20pcnt Castor & Methanol mix.
Hi! Will be this engine enough for hangar 9 corsair 50 they recomand 4-stroke .72 - .82? I dont want to buy biger engine - i dont need fly half or les trottle like on my kyosho me 109 it has 0.46 2-stroke and it is too much for me. They are same wingspan about 1.4m.
I think this gets about5-5.5lbs of thrust on a 13x4 k series master airscrew prop. So, the plane will be under powered. ********** has a asp 70fs for just a little more.
you have to use a motor helice four times, the master Airscrew K series, or even use an APC 11x6 just do not use as the manual says that the motor rotates too much, hitting valve, use 12x6 up.
Hi, my brother has the bigger FS91AR in the .46 plane... :) verticals at 1/2 throttle.
About mine, I bought this FS61AR for Ultimate-40 airplane, I think is the right powerplant for unlimited verticals. My other planes are all overpowered of 1 class... it's not for beginner, but for advanced pilots.
the FS61AR is not over kill in a 46 size plane as I run on in a hanger 9 P51 D the engine does swing a larger prop at lower revs than a 46 2 stroke but the higher torque makes it. go ahead and give it a try you wony be disapointed
Hola Valdecir,tenes que usar un combustible para 4 tiempos y que tenga un porcentaje minimo de nitro del 10%,la vela o bujia es una O.S modelo F funciona de maravillas.Aca en la patagonia argentina yo lo uso con el 5% de nitro y funciona bien,pero es mejor un 10% o mejor aun un 15% de nitro
works better whith 11/7 two blades dependeds on your model im mount to spitfire 50-3.5 kg. mounting to your plane and first prove to pull up!second takeoff!
I'm going to be upswing this Ina boat I'm building it's got plenty of cooling but what boat prop should I use? It seems like a fine running engine for the price.. Or should I jus use the 15cc gaser? It's 36 inch shovel nose hydro. Thanks in advance
Be careful. 4 stroke aircraft engines run very hot.
And thats with the prop cooling it.
I recomend a water cooled engine from hobbyking.
However i dont think they have a 4 stroke version.
Good luck.
whith 0,4 fly 10 min and landing whith 1/4 tank glow

46 thumbs up!
I bought two of these engines , both started straight away and run perfect even down to a low idle using 10pcnt nitro - plenty of power using a 12 x 6 propeller and economical on fuel. smooth transition from idle to full throttle. i am very happy with the motors for the price.

This engine is out standing. It started on the first try, no problems. It was pre set from the factory so I didn't need to do a lot of adjusting to it. It's worth the money believe me.
Wow! super engine. I use mine in a 40 size low winged trainer. Plenty of power, easy to start and running clean. Would recomend this to anyone! Perfect to use later on a 40 size acro plane too. nice!

Great engine , I was suprised how well is runing .I am having it in a Texan .46 and 12x7 prop. I will buy the .91 too. Stefan
Great engine - very happy. Make sure you prime it until it is literally soaking in fuel and then it starts easier than any other engine I have come across. With a 500cc fuel tank I get around 15 minutes of mostly full throttle running a little on the rich side with a 11x7 prop.
