Just picked up the kit yesterday, will start to build after I am finished with my wife's slow-poke, anything I should look for, as in tip's or trick's for the Hog?, already have done a search on it & did not satisfy my need to know.

Mount the gear 1/2" to 1" forward of the normal spot. Make a bigger, thicker gear mounting plate if you like, you'll appreciate it later on.

Don't cheat on the CG. Make sure it's at their suggested location or up to 1 inch forward.

Have plenty of elevator throw (maybe 2" overall) and damp it down with dual rates or expo. You'll need a lot of throw to flare at a low speed.

Glue washers to the wing struts before covering. Without washers the little 4-40 screws will go through that lite ply pretty quickly.

If this is your first bipe, have someone else with experience do the maiden.

What engine are you planning to use?

either a Saito 100, 91 or an 80

Those are all good choices, they will just make for different flying styles.

You can fly the Hog with an OS 46FX, its just gonna fly like an underpowered trainer. I've got a OS 91FX on my new Hog, had a OS Surpass 70 on an older plane.

The 70 four stroke was fine, but marginal with floats. The 91 two stroke pulls it vertical for sure!

With the 91FX I had to move the servos and battery back, behind the fuse opening. You might have to do something like that with the 91 or 100.

rwh, thanks for the help, I am partial to O.S motor's as I have been running them in my truck's & car's for year's & have found them to be a very reliable motor.

The Saito motor's I have never used & they were recommended to me from a fellow flier.

As for someone else taking her up for the maiden flight you betcha, I find after spending all the time putting her together from stick's I would be to nervous, as always, to take her up myself. for some reason when I fly a kit I am just a little bit more cautious than with a RTF.

Yes this is my first bipe, well not really if you count the ones I use to build & cover with tissue, of course that was about 25yrs or so ago, did allot of searching & reading up on the subject & figured the hog would be ideal for my first bipe, I alway's seem to be drawn back into this hobby. ;)

mrisis,
you have nothing to be worried about with the Hog Bibe. I've had 3 of them and it's a very forgiving plane. my only advice for building it would be pay attention to your CG (as stated above) and make sure your wings are at 0 incidence.

as for flying it. it's very forgiving in the air. but if you've never flown a bipe before, your landings are a bit different. you really don't float them in as you would other planes, but rather you are really going to have to fly it in. the glide slope for the bipe is a lot steeper. but other than that, there is nothing to be afraid of with the hog bipe.

RCKen, thanks for the boost in confidence.

I bought one used from the LHS and I'm not sure if it was built right. When I do a roll if I don't pull the nose up to about a 35-45 degree by the time it completes the roll it is pointed to the ground. I have the ailerons at the max deflection and my radio is set as high as it will go and it still does it. I have one club member who says that that is normal and another says it should roll like it was on rails. I am flyng a OS 91 4 stroke with a 13-8 prop. So who is right?

The one who says it should roll like it is on rails. The hog bipe should do a fairly good roll. maybe a little up elevator to keep in on an even line, but it definately shouldn't drop as much as you said it does.

Any suggestions on what could be wrong? CG is set up according to the manual. The engine is tuned right as I have enough power to do stall turns and other vertical manuevers. The servo moves to the stops and is high torque.

Tim :confused:

It sounds like your CG is too far forward. Do the dive test: Climb fairly high and dive straight down at 1/4 or less throttle. Let the elevator stick go to neutral. The plane should continue straight down or pull-out very gradually. If it pulls-out fast, the CG is too far forward and you can add tail weight (1/4 oz at a time!)

You should always make sure the basic alignment and control system of the plane is correct before making changes to the CG.
