Sig Hog Bipe build
 

Hey kit peeps... Got a Sig Hog Bipe the other day and was searching for build threads or advice on what to avoid while building.
Anyone build this and have advice?

Was hoping to build and fly her in the next few weeks. Doable? off work on the 16th / 17th, and again on the 30 / 1st for jewish holiday (not jewish, but loving working for a jewish company :D) and wanted to have her out and flying by then...

You're gonna love this plane - I still regret selling mine. Here's a link to a review I wrote in '98 (gosh, time sure flies!)

RE: Sig Hog Bipe build
 

Thanks luvbipes!

Question: Did the turtledeck behind the cockpit get sheeted? I hate the exposed stringer look...
I flipped through the instructions briefly on the can and dont' remember seeing this, nor sheeting in the box for it...

RE: Sig Hog Bipe build
 

Just finished mine a couple of weeks ago, but with work etc, I've only got three flights on it...well 2 and a bit flights...I had one of the older guys, pardon me, "more experienced" :D guys do the first flight...I did fly it, but he took it off and landed it.

Yes the turtle deck is sheeted. You have to cut the pieces for it from the sheets in the box. Mods I made were to move the main gear ahead about an inch, dual servos for the ailerons(easy to do since the instructions/kit came with all the extra bits) and a Sullivan tail wheel. Mod I wish I had done was use a size or two larger blindnuts for the main gear to allow for using larger nylon bolts.

As for how long to build...I can't give a good answer...with work etc, I'm a slow builder...but remember, with two wings to build, it will take longer!

If the weather is OK, maybe I'll get another flight in on it this weekend!

RE: Sig Hog Bipe build
 

Let us know how it flies, I am covering one now.

Eric's Fubar Hill has a ton of info on Hog-Bipes in various trim schemes, with construction mods, engines, etc.

RE: Sig Hog Bipe build
 

Sweet thing you got, very aerobatic an fun to fly.

RE: Sig Hog Bipe build
 

I have put more than 50 flights on mine this year. It is a great plane for allround fun.

RE: Sig Hog Bipe build
 

Good stuff here swooper! Thanks!

Planned on moving up the landing gear as was mentioned before... what I'm thinking is: try the stock, and if I don't like I can move up an inch by reinforcing the ply infront of the landing gear plate... drill some holes, 1/4 20 blind nuts and nylon bolts...
Also on the tank making a hatch... hate not having enough fuel specially on a fun plane to fly :D

ps swooper... the one image on Matt Winter's P-47 (another kit in the works) 1st image has a bad link to a popup thingey (link is http://zeus.rcwizard.com/fubar_hill/images/mattjug.JPG but people do not click it!)

RE: Sig Hog Bipe build
 

Plan on a stronger servo for the rudder helps a lot when you knife the plane, which engine are you planing to install?

RE: Sig Hog Bipe build
 

funny you should ask.... kit reccomends a .60 to .65 size, AND NO LARGER muhahhahhahahahaha

I was hoping to get a Supertigre G-75 for her. I bought a G-51 ringed and am in love with it. I can flip the nose cone backwards and she fires to life with a click up of throttle... I was gonna ask what yall thought of .10 over the recommended engine range.

If it wont work or I get cheap I have a TT .61 I used for the engine mount size. May maiden her and fly with that one for awhile.

RE: Sig Hog Bipe build
 

I am finishing a Hog Bipe.

Was thinking of using a OS 70 four stroke. Or would a 91 be better ?


Thanks,

RE: Sig Hog Bipe build
 

LMProd...

How long did the build take you? I've had the kit for a few days and already have the fuse done and the top wing 3/4 done. Think it's gonna be done by next thursday? I WANNA FLY IT!!!!!!!!!

RE: Sig Hog Bipe build
 

LMProd, the 70 flew my HB just fine, but if you're into "hot dogging" a .91 is the way to go. A 13X6 APC is a good prop to start w/, on the .70 by the way .

RE: Sig Hog Bipe build
 

LuvBipes, Thanks for the info

I am not into Hog Doging and I thought a 70 Fourstroke would work well. Plus I can use the 91 in a Tiger Moth.


Crash Johnson:
It has taken me an estimated two years to build. Set is aside for a while, Got busy, built to ARF, and went back to flying full size. Missed building and flying RC planes.
So I dusted off the Hog Bipe and finishing it.

RE: Sig Hog Bipe build
 

The 70 will make it fly, the 91 will make you enjoy it.

RE: Sig Hog Bipe build
 

Crash, my first Hog-Bipe first had the ST G-75 and was very powerful at 6000 ft. You should love it!
Later it got a Thunder Tiger .91 4-stroke, which later went into my 2nd one. Looks, sounds, and flies great.

RE: Sig Hog Bipe build
 

I've got a Fox 74 in mine w/ 13x6 zinger. It tachs 10,900 rpm with 0% nitro. Fly 3/4 throttle all day. Might just take it vertical if I leaned it out. Had a ST75 in a four star, its not as powerful as the Fox and about 4 oz heavier. The ST 75 will be great in your bipe. I love this plane and you will too wether you put in a 60 or the 75. Definetly move the gear up but I would think an inch is too much. I'd try 1/4 to 1/2" I've heard some thoughts that the landing gear area is a little weak moving it up gets it further from the bulkhead that adds strength. With gear on orginal postion the plane likes to nose over on a grass feild taxi. I tried moving gear up 1/4" by drilling new holes in the gear. handling is improved but gear was shaky, ended up moving it back. I have to take off with full up elevator. The big 16 oz tank compounds the problem a smaller tank would help but I like to fly.

RE: Sig Hog Bipe build
 

Cool thanks for the advice guys!

Got some SERIOUS building done Sunday and should be ready to go hopefully this Friday or Sat. Got the fuse, top and bottom wings framed and ready to start covering :D

RE: Sig Hog Bipe build
 

My son will be building this as his first build. I'll be helping, of course. I love your scheme, and I think that we will copy the pre WWII scheme for the Bipe.

Thanks,
Lew B

RE: Sig Hog Bipe build
 

Just about done covering mine going to put a 91 saito in the nose, need some advice on a prop.

RE: Sig Hog Bipe build
 

I got my SuperTigre 75 and I'm going with a 12x5 or 13x5. Not looking for super killer speed, I don't fly too fast, looking more for hover capability. Chances are may have to go with a 14x5 to hover her.

Prop selection all depends on what you wanna do with the plane. Sport flying for fun, go with the recommended prop for the engine.

RE: Sig Hog Bipe build
 

I'm glad to see a post on the HB. I purchased a Mag 80 on sale for 129.00(couldn't resist the price, after I said I would never buy a 4 stroke). I plan on building a HB soon, probably this winter. The Mag 80 should be ok for this plane?

RE: Sig Hog Bipe build
 

Keep on posting!, I got one in the box for this winter build, it will be powered by a Thunder Tiger 91 FS, I don't think I'll modify anything since I fly off asphalt runway, any input on this?
Joe

RE: Sig Hog Bipe build
 

Don't know first hand about the Mag 80 on it as I am still about 75% done on the build. Should work out and if it isn't as powerful as you need, just upgrade :D

In hindsight I sorta wish I did a build thread on this plane... Was gonna in the begining but ya know how that goes. By the time you realize it's half done and who wants a half build thread?
I'll get some pic's of the uncovered fuse for yall for motivation ;)

RE: Sig Hog Bipe build
 

oh yea.. modifications:

I kept the gear where it was, and if I wanna move it I'll add some ply and move them up. Doing the dual aileron servo's, and gonna make a tank hatch to increase the fuel tank if 14oz aint enough.

thinking about smoke on her :D gonna figure that part out after the season is over and have time to mess with it. Don;t know what mine is going to weigh, and don't wanna make it much heavier then the recommendations.

RE: Sig Hog Bipe build
 

Joe, I shortened the nose 1/2-inch for my TT .91 4-stroke and it balanced nicely, but I can't run a spinner (too heavy). Therefore, I don't think you need all that nose length with this heavy engine. Here's mine in Ultracote.

RE: Sig Hog Bipe build
 

I put a 14x6 prop on my Saito .91. Great combo

RE: Sig Hog Bipe build
 

Just fineshed my HOGBIPE!! Red and yellow monokote. I'll try that 14x6 this will be my first bipe is there anything I should know before the maiden flight??

RE: Sig Hog Bipe build
 

I built one a few years back, then bashed it to a Pitts wannabee. The windshield gave me fits, so I made a solid canopy, ditched the headrest, and made a sportier look out of it. I flew it off of a OS .61 with great results. Stronger tailwheel and landing gear were my first mods after flying the first few times. I learned quickly that with some biplanes two wings equal more lift, but also more drag.

I tried bashing it, unsuccessfully, into a Pitts wannabee. I added foam to the fuse sides to beef it out and put a Super Chipmunk cowl on the front. Changed the tail to more rounded control surfaces. Then it came out really heavy. Looked cool, but really flew like a hog after all of that. I couldn't make it go through loops without falling out 3/4 of the way up. Stall turns were a breeze though....

I still have the wings in perfect condition if anybody is interested. I could probably let them go for really cheap, I was thinking of buying a replacement fuse kit, but then bought a Skybolt instead.

RE: Sig Hog Bipe build
 

Hans just remember to apply a little right rudder on takeoff and remember to have fun :)

RE: Sig Hog Bipe build
 

Well, about a month later and I am finally done :D

Got some images as well. Put in ALOT of time on it (probably 200 - 300 hours total). Going to maiden it out at the field today / tomorrow / friday / sat / sun...

Oh yea, on the covering job.... going to do the same thing on the feathers that I did on the tops of the wings... red leading edge and a blue strip with stars cut out.

Bottoms are white now (no time to get detailed, wanna make sure she flies good first and is worth the effort :D) but I plan on doing the middle of the wings by the fuse with blue and cut out stars, and extending towards the wingtips red stripes so the bottoms will loook like the american flag. It's my little homage to the men and women who fight for our freedom. least I could do.

RE: Sig Hog Bipe build
 

Looks great Crash, I got one in the box, still trying to figure out witch winter project I'm going to tackle, the kits are starting to pile up rather fast, lot's of planes that I want, but no time to build them[:@]
Joe[8D]

I built a Hog Bipe once,It preaty straight forward,Except the only challange was lining up your wing stand offs. And you want to make shure your ailorons for top and bottom wing have identical throw.
