The Q-Talk article describing the JimBob 6-pack can be found here: http://www.quickheads.com/index.php?option=com_content&view=article&id=1165:q-talk-108-the-jim-bob-6-pack&catid=48&Itemid=101
I went through it in August as I was baselining the current work completed on my airframe. Voice of zero experience here, but perusing this list, the archives, and Sam's new and old blogs led me to believe the following revisions may be in order: 1. The bellcrank can be eliminated for the Hoskins setup, reducing weight, build time, and complexity (esp. if combined with the plans quick disconnect). To finish rigging my current bellcrank I think I'll have to wear the tailcone as a hat. Not looking forward to annuals either. 2. The LaRue brake mod is good but superceded by the Coughlin/Hoskins mounting. If reports that you can reuse the stock mounts and wheel covers are true then that's more build time saved. Grainger now sells threaded hollow steel rod of the correct size, making construction of the Coughlin version much easier. 3. The full-swivel tailwheel is nice to have but *potentially* unnecessary (or at least a decision/modification that can be deferred). 4. The Gall wheel alignment must also be completed as the 7th item on a taildragger, especially if operating at high gross weights (the existing alignment problem gets progressively worse as weight increases). 5. Having some sort of independent hydraulic brakes is more important than them strictly being the Matco-type toe brakes called out in the article. I considered heel brakes as a compromise to keep my hands free but a simple bungee rope parking brake across both finger levers may adequately solve the problem... My aircraft currently has the entire 6-pack and Gall alignment completed per the earlier link, except for retaining a stock tailwheel. I intend to revisit items 1, 2, 3, and 5 *after* flying the 40 hours and revising my opinion then (so JP/MD/JM don't burn me at the stake). -- -MD #2827 (still thinking about planning on visualizing how to finish building)

I put dual cylinder finger brakes for that directional control.
From: main@Q-List.groups.io <main@Q-List.groups.io> On Behalf Of Sam Hoskins
The problem with the single pull brake is a safety issue. If the tailspring should break, you lose all directional control. With differential brakes you would be able to keep steering the aircraft.
When I had around 1,000 hours on my Q-200, I was getting my BFR and the tailspring broke. I had the per-plans installation. So, touching down at 70 mph and no steering available. We went off the runway and I forced a groundloop my throwing the control stick to the right. Adverse yaw induced the groundloop. The left wheelpant broke off and bounced off the canopy. The resulting prop strike trashed the prob and bent the crankshaft. And, I didn't even get my BFR signed off!
So, during the repair I installed differential braking and split the cables so an independent cable is connected to the rudder and to the tailwheel.
Of course, if I had a tailspring that didn't break, the problem wouldn't have happened, but that's another topic.
Aside from the loss of control issue, I like differential braking a lot more than single pull. You can turn a tighter corner and generally have better control on the ground.

Re: Q2/200 configurations
I have toe brakes, but that is standard for the Tri-gear. However, in anticipation of maintenance, I did two things. Both of these can be done on a taildragger, to the same effect. 1. I created two ports in the sides of the fuselage for better access.
2. I built the rudder pedals and brake assembly on a removable platform that bolts into the canard and firewall. Note the aluminum angle attached to the platform that allows brake cylinder angle adjustment. I also have a rudder trim servo attached, but that is a little overkill (https://youtu.be/sKq6PnsM8XU ).
The platform approach gives the most flexibility if you need to do a brake cylinder replacement, or rudder assembly overhaul, or you wish to change the position of the rudder pedals easily, should there be a shorter pilot that takes over after I have had my fun.
Pictures of both mods attached. The platform is held down by two bolts and two nuts (on studs mounted to the canard). The platform can be lifted outside the airplane through the port without disconnecting the brake lines if needed.

I have a really nice finger brake module I designed that you can build entirely out of the airplane and then just glass in place with some tapes. It allows for easy removal and maintenance of all of the components.
I don’t have the space for feet and brakes and I found the maintenance to be an issue.

It isn’t needed, but it sure makes doing annuals easier.
From: main@Q-List.groups.io <main@Q-List.groups.io> On Behalf Of Sam Hoskins
I am going to throw in my opposing two cents worth. I think that the additional JimBob bellcrank is an unneeded modification. I think it is a fix in search of a problem.
Yes, if you have the stock setup, with the rudder cables going to the tailwheel bracket, then to the rudder bellcrank, it is a bad design due to the complete loss of rudder if the tail spring breaks. I have first-hand knowledge of this problem. Rather, a simpler way is to simply tie in a second cable that goes to the tail. This way, there are separate cables; one to the rudder and one to the tailwheel. I'll attach a photo to show what I mean.
I know that several guys installed the JimBob bellcrank, but I don't think it is needed. What is needed, is to make sure that the Gall Wheel Alignment has been performed correctly. The root cause of most handling issues is the improper wheel alignment method what was called out in the QAC plans. When QAC wrote the Q-2/Q-200 plans, they simply cut and pasted the Q-1 wheel alignment. Doesn't apply to a substantially heavier airframe.

Re: Q2/200 configurations
Hi Mike, A case in point was Tom Moore’s Q200 that Brad Olsen bought. He began taxi testing and was all over the place. So I went for a hi speed run to see what was going on. The plane seemed very twitchy and not predictable, I didn’t like the handling, so Bob F and I suggested he install the sixpack and he did. The subsequent hi speed taxi’s, take off and landings were totally tamed. It is a nice looking good handling, fast airplane. If I were building or finishing my plane again, I would incorporate the same mods. They allow for more input finesse. Just another view. That’s why they call um experimental.
Whenever we get to go for a ride in mine, I will show you.

Mike,
I think it’s a matter of personal preference based on whether you have toe brakes or finger brakes already installed And are flying with them. As a practical matter, toe brake cylinders are much harder to install and service and I think that deters a lot of people. I love having toe brakes so my hands are free for other things. To each his own!
Also as Paul stated, if the tail rod brakes you still have total control of the rudders and brakes with our Jim/Bob bellcrank modification.

All true. The pivot in the tail cone splits to separate the rudder from the tail wheel. Great control results from that mod! Bruce
