Do you guys think a 1.20 Surpass pumped would be too much in a Hog Bipe? I plan on putting a smoke system in it and have the tanks at CG. I was thinking maybe a 91 FS would be good enough, but have an opertunity to get a 1.20 Surpass with pump.

Anyone have a hog with a 120? Thanks and I'd like all opinions.

I like to fly with lots of power, But if it's gonna ruin the flight carracteristics then I don't wanna do that.

I used to have a Hog Bipe with a .91 four stroke in it... in my opinion it was not enough motor so the 120 would probably be better. That's my .02.

My son has one that flies beautifully with a Saito 91. However, if you are one of THOSE for whom overpowering is a compulsion not a choice, then the V-8 put out by Toyota has great power and it responds to input very quickly. Now a motor mount could be a problem..... Sunny_B

Well, I want good verticle with it. I had a Saito 91 in a Funtana 40. That was a bit overkill and thought that it would power the hog just fine. But if I'd prop. the 1.20 right, so it wouldn't be so fast then I'd be happy. I just am wondering if the extra 10oz. of weight would be bad for the plane?? That's the difference between a 91 and 1.20.

I do like my planes overpowered, for those knee buckling times. I'm just seeing if anyone else has put one in the Hog and how it flies.

I have an OS .91 that does a great job. Extra weight (and loading) might be an issue. Working with different props has made a big difference. Initially I went to a 15x6. Messed around with a few and landed (pun intended) on an APC 14x8.

I have a friend that built the Hog bipe and put an OS 91 four stroke in it. Because he is still on a trainer, I get to fly his other stuff, like the Hog bipe. In my opinion, it has enough power for what the plane was designed to do. If he had built it a bit lighter, it would be that much nicer. If you are worried about weight and want more power, look into the YS 110. What I am doing on my 120 sized planes is going to a bigger prop / less pitch. On my QQ Yak with a YS 140 L, I am running an 18x6W. I have the power I want where I want it.

Well I have a FPE 2.4 and a guy offered to trade me for his NIB OS 1.20 pumped with Slimline pitts. I guess if someone offered me a trade for a YS 1.10 or 1.40 i would take that. Cuz I could use the 1.40 in my 120 Edge.

But I'm getting a Hog Bipe soon and will need to fill it. I think I want to put either a 91 FS in it or a YS 1.10. But the 1.20 will be too much weight and power. I could however put the 1.20 pumped in my CG Sukhoi. It isn't finished yet. Just one wing half built. I ran outta steam. ARFs are ruining me. AHHHHH

I've had 3 Hog Bipes and all I can say is the plane WAS designed for a 91 4-stroke. if you put that huge 120 on it you're gonna have several problems. first off is weight, you're gonna have to add a ton of weight to the tail to compensate for that big engine up front. second off, all that extra weight is gonna put a lot of strain on the landing gear, beef up the the area around the landing gear in case you have a less than perfect landing. The hog bipe wasn't made to 3D, so you don't need a motor that big on it. A 91 4-stroke has all the power that the Sig Pig will ever need. If you just absolutely have to 3D a biplane, then don't get a Hog Bibe, but rather get an Ultimate Bipe or Chip Hyde's Double Vision because those ARE designed for 3D.

just adding my .02 cents worth

Ok. that's what I was wondering. I'm leaning way more towards a 90-100 Saito or OS. I just had a good offer on a 1.20. That's why I was asking. I don't want to beef everything up and fly a brick. Because I know bipes are pretty much bricks with wings anyways.. thanks RCKEN

I have the 120 S in A Boing Bipe, the F4B-2 that was 12 pounds when complete but due to the incorrect CG given on the plans I had to add several pounds to the cowl, it is now 15 pounds and the 120 pulls it around very well as far as scale flying goes. Just give that some thought and you will see the over kill you would have. I used the 110 YS in A 8 pound Krier Kraft and with A 16X6 it was beyond great for vertical but I slowed it down with A 14X10 so it wasn't so fast. The Hogs I have got to fly have all had the OS 91 in them and it is more then enough for such and nice light plane. Still, I just love my YS and plan on building another plane around it.

iowasilvia, i fly a "bashed" hog bipe, with a saito 91 & 14 x 8 apc. it's a bit heavy, due to sheeting the tail feathers, and internal pine stiffeners. fuel consumption is about an ounce a minute. my TAUBE has a 120 pumper. 96" span and it uses TWICE THE FUEL.
i have another HOG on the board now (stretching both wings two rib bays) and i plan a saito 91 for it. trying to build lighter and still resemble a 1925 curtiss hawk.

Just maidened my Hog Bipe last weekend. a couple of things... I've got a Saito 100 on it, flew it with a 15/6 zinger, and it's plenty of power! If you're going to put that 120 in it, seriously consider doing some calcs, and move the firewall back! They come out kinda heavy as it is, so you don't need to add more weight to balance, move the firewall.

if you go any larger than a 15" dia. prop, you're gonna have trouble. The 15 just barely clears, and you'd better grease the landings or you're going be breaking things. with the 100 on it, it's got more than enough vertical penetration. I found myself flying it at 1/2 power most of the time, only opening up the throttle for LONG uplines.
