I just finished up a ARC Brodak Bi-Slob.

This is a great kit. Parts are all laser cut and fit well together. The wood seems good. Not sure I could tell you if it is contest type wood, but not sure you want it in a Slob.

Here are some of my thoughts. None of this is in the instruction booklet, but I think it should be like a extra note for dummy's like me.

• You will need to trim down the exhaust side of the fuse to keep the exhaust stack from blowing right on the wood.
• You will also need to trim about 1/4 inch off the right side of the motor mount and trim the fuse so the prop will clear the nose. If you don't the prop will not turn over.
• You should mark the bottom and top wing and double check where the tip weight is located before you glue the wing in. Ask me how I know.
• And make sure you get the flaps glued on the same way on both wings. If not you will have to cut out the connector horn or the hinges. Either way you are cutting. Again ask me how I know.  

Bottom line this is a great kit and for the experenced builder it is a slam dunk. But I hope this helps people like me, that still struggle a little with each build.
And it is a kick in the pants to fly!

Next one you do , don't cut the front of the fuse to clear the prop. I made a plywood disc and fit that to the Fox 35 shaft for the clearence that I needed. I don't remember any outboard wt on the wings but if you say it is there then it is, however aligning the rod hookup tabs will automatically guarentee you that you have the weight where it belongs.
Now get out there and have fun. I did tell you that I fly mine on a paved circle. Nothing like the smell of asphault to get your blood flowing with a slob.

I have 2 one with an OS 35 s and the other with a Fox 35 . 58 foot lines a10/5 prop  and the largest tank that will fit 4or 41/2 oz.

Paul; I added a little tip weight to both wings, and then added a square piece of 1/8" ply to each side of the outboard strut. I drilled a hole in the ply for a 4-40 socket head cap screw and an elastic aircraft nut to hold lead weights. Shuzam! A Red Neck tip weight box.

Paul, I do have to say, that is probably the best looking Slob out there, now don't ruin it

Ken Cook said:  "I installed 1/32 doublers within my fuse from motor mounts and just past the bellcrank platform."

The plans I drew for the Flying Models article has doublers as you describe. I have never seen the kit or Arf plans, but that doubler should be there.

As for the prop clearance at the nose, either sand the outboard side down , or install the engine a little further forward. No big deal.

Interestingly, all of Ron Pavloer's "Slobs" had card board fuselages. The original "Slobs" used A Fox .35 or the original style Fox .25

My "Slobs" have a 4 ounce tank. I also add a blind nut in the middle of the outboard strut. This will allow you to bolt on additional weight is necessary.

Neal is right on with the line length.

     This based solely on my experience so I'm not looking to get flamed here. I have assembled the ARF version and built the kit version. I love them both. My son flies the kit version while I fly the ARF. I don't know if the ARC has the aluminum plate within the motor mount area or not. I believe it was added due to the wood that was removed out of the hardwood mount for the engine offset. In my opinion way too much material has been removed and there is too much offset. This offset is not needed and my kit version has no offset and it flies with the best of them. The offset as stated above is so great that the prop is hitting the cheek on the outboard side. The problem with the ARF version is that the holes are already drilled and without a major rework its just as easy to just take down the cheek and install the engine. I can't comment on the ARC as I don't know about its construction or if the holes are drilled. We fly many slobs on a regular basis and for those that are concerned with that engine offset I know its not needed to the degree the ARF's provide. Now as for the rudder, don't change that as I've found its very important to its flying ability. I snapped it off inverted one day and decided its really not a big deal so I put it in the air again. I did learn not to do that again as it kept trying to almost roll inboard. Ken

I just bought an ARC, maybe I'll get it before the holiday. Lots of great info guys, I'll use one of my Fox 35's. We fly at the Mt Joy airport so no muffler required. None of the guy's at the flying field have one that I know of so it should give us some laugh's. can't wait
