I am trying to choose the best 4-stroke glow engine for a Pulse XT 60. http://www.horizonhobby.com/Products...ProdID=HAN4130


The recommended 4-stroke is a FA-100, but with the new FA-115 coming out, I would like to know which would be better. Would the 115 fit without modifications? If so, I would like the extra power.

Thanks for the help!!

The Saito 115 has the same size case as the .91, and more power than the 1.00. It should be a nice combo.

The only thing I would be concerned about is the distance from the firewall to the front of the cowl. I have a Pulse 40, and I put a Saito 82 on it. I had a tough time getting the engine close enough to allow the cowl to be mounted in the proper position.

According to the Saito 2008 catalog, the distance from the rear of the carb to the front of the crankshaft threads is 116 mm. (That is only 12 mm more than the same dimension is for the 82, and exactly the same as for the Saito 91.)

I don't know the distance from the front of the crankshaft to the front of the prop washer. That would have to be deducted from 116 mm to find out what the distance from the rear of the carb to the front of the prop washer would be.

If you had that dimension, then you could download the manual for the 60 sized Pulse, and you would know if this engine would fit well.

Or, you could just buy it and MAKE it fit!

I think that would be a very nice combo!

That pointed me in the right direction. I downloaded the manual for the Pulse XT 60 and it shows the distance from the fire wall to the drive washer as 146mm, so there will be plenty of room. I ordered both, so now I am just hoping the Satio 115 is a good engine. I have only ever owned OS 2 strokes.

Yep, you should have PLENTY of room for your 115.

The 40-sized Pulse has that dimension listed as 102 mm, and the dimension for the Saito 82 I put on it was 104 mm. I had to get pretty creative to get the engine to fit in that space!

I"m sure you will be happy with your plane and engine combo. If you find you have any questions about your engine, come back here and ask. There is a lot of experience and wisdom available here. (Not me, but lots of others.....)

I just checked out the new 1.15 at Horizon's site, it is in the new style case, I've been trying hard to not be interested in getting one but am failing fast. I have an understanding with my LHS which is 370 miles from me, that I get the first of any new Saito model that comes out. Judging by the bore and stroke it should be a revver but will most likely be a torquer like the 1.25. Descisions, descisions.

Billslagle1

Well I have mine ordered, the plane is shipping today but the engine is backordered...supposed to be in late may. What do you think the difference will be compared to the 100? I'm no engine expert. Do you think it will be more torquey than the 100? I am hoping it is better on fuel than the FA-125, I heard that thing is very thirsty.
Also any suggestions on what servos to put in this Pulse XT 60? I have a Futaba T6EX 2.4GHz.

Thanks!

My 1.25 is very economical on fuel.

Will the Pulse 60 fly ok with a saito 91,I have one NIB ????

Ken6PPC

That is the minimum size 4 stroke engine that Horizon recommends for the Pulse 60.

Your 91 should fly that plane just fine.

I was just flying my Pulse 40 Saturday, and I have to admit that I had forgotten how much fun that plane is to fly. If the Pulse 60 is as much fun as the 40 is, I may have to get one!

I have a Saito Fa 125 GK up front of my pulse xt 60( over kill ), no problems fitting it onnor was there any problem in fitting it with cowl, nothing my dremel drill would not shape around engine cowl. One thoughproblem was nose heavy because of wheight of engine, but lead wheights fixed problem witch I put at the backof the fusulage. I did this by drilling holesin the lead wheight andscrewing of nut that holds elevator and rudder then placing lead wheight in to screw, and tightening nuts, so far no problems. Engines is quite, and has heaps of torque, flys superblyat heigh and low speed and lands extremely well at low speeds vertualy floats. But, after 10 flights A screaching noise was present from my saito, Landed plane emediately, all brake in procedures where fastidously done. Still Awaiting news from supplier ( could be bearing). Heard also someone else having some problem and symptoms), a week earlier. Bit disappointed as Saito produce the best 4 strokes in bussines. The 125 does drink fuel but because I am running it rich, I can get 8-12 minutes of flight time with (15% nitro 18% oil and rest meth) ( Thats 7072 turns with mechanical pump 200mm-300mm I think. Etheir way if you dont experience any problems like I have which could be down to bad luck, the motor selection and plane are a fantastic combo and im only a newby at this sport but learning at a rapid rate.
