Re: Operation Special Cub

All,
Thanks for the inputs. Couple quick questions. Denny, what is the advantage in sliding the 696 up? Why will the Cabin heat be hard to reach? Thanks for the EGT comment. I knew I was forgetting something.

Skinner, thanks for the radio suggestion. It will be on the short list if I decide to pony up the $$$ on a new one. Regarding the aux input. That sounds awesome. Is there an intercom that incorporates it or do you wire in your own aux?

N419A. Nice looking setup. If you decide to buy panel planner call Gene up and ask him for the $245 Oshkosh special. The website price is $295. I have three beater airplanes that all need panels so I decided it was a worthwhile investment. I haven't regretted that decision. It is the bombdiggity! That said, what brand of EGT and voltage gauges are you using? Those are the ones I had in mind and I searched for them but couldn't figure it out when laying mine out.

Also, I plan to utilize the circuit breaker Toggle Switches that Skinner mentioned to the max extent possible. That said, what circuits can't I do that on? I need an avionics, master, strobe, position lights, landing lights etc. Can't all of theses be on circuit breaker toggles vs actual circuit breakers? advantages/disadvantages?

Re: Operation Special Cub

A lot of the intercoms have the aux input available. I just added one on a PS 2000, plug had accommodations. Also did a PS 1000 install before Christmas and it actually came with the small jack required for it. The PAR 200 has it built right in I believe, but definitely has provisions for it. The newer sigtronics have provisions as well, but te older 400 doesn't. Nice thing with the until that have provisions is that they auto mute when the radio is keyed or transmissions are being received.
While we are spending you money, EI has a rebate on the CGR 30 again. May be worth replacing your rpm with it and getting the added benefits of the bar graph cht/egts and fuel flow...

Re: Operation Special Cub

Hendo,
I have the EI EC-1 single channel CHT/EGT in the cub, I have the same gauge in my 170 but with the switch box for the four channel. It's simple and works fine. The amps/volts is also EI the VA-1 also very basic. I am also moving all my switches to the panel and eliminating the wing root panel and I will use all breaker switches and push pull breakers in a removable plate. We did this in my brothers cub last year and it worked out well. I also have had really good luck buying the Tyco W31 breaker switches and Tyco W23 push pull breakers on ebay for a fraction of the price other shops sell them for, all were new.

Re: Operation Special Cub

Pushing the GPS up has two advantages. First is it allows more room on the panel, second is it allows you a bit more peripheral vision outside the plane as you are trying to find that lake, stream, or other point you are looking for (it is what all the cool pilots are doing). The cabin heat cable nut on the back is what will be hard to reach if it comes loose or you have to replace it. The radio slide in trays won't let you get a wrench in from the side or top. That only leaves the bottom to try to reach up The switch is in the way. Most put a bend on the bottom of the panel to stiffen it, that also can be a pain to work around.

I have my switches/breakers on the bottom of the panel and although I like them there I did sweep a switch off with my Bunny Boot few years ago. Not a big deal, it would have cost a lot more if it was a radio or transponder knob.

Heel brakes really shine when you are in big boots. It only took a few flights for me to convert the from pacer toe brakes I was used to.

Did you get the picture of my panel?

Removed the interior of the cub today. Pretty dirty, but everything looked solid with no rust or corrosion

Removed the battery and the Windows.

Re: Operation Special Cub

Jealous of the CGR-30P Tom! How do you like the Trig? Is the Trig one of the remote models? If so where did you mount the radio unit?

Re: Operation Special Cub

All,
What should one expect to pay to have a cub panel blasted out on a CNC if I provide the design file? I'm getting quotes all over the page. I don't mind paying what it's worth but don't want to pay a premium either. I would like to have a test panel and a final panel cut.

Re: Operation Special Cub

Dump that radio and intercom and put a Garmin GTR200 in. Built in intercom and the aux audio capability. I put one in my previous plane and loved it, great radio and clean easy install. I got mine from Aircraft Spruce and bought their harness option which worked great.

This is a great recommendation. The more I've thought about it the PAR model really is overkill for this type of plane. Even a GTR or icom 220 would be great. And would give you a bit extra to spend elsewhere.
Great thinking Prosaria!

Not sure if you're generalizing when you say CNC (CNC mill is what I think of), but I would recommend a waterjet place do it. It's very cheap and fast. You can pay different amounts for various edge quality (how fast the thing cuts essentially), so the test panel can be cheaper and the final can be nicer. You could also test it on polycarbonate or something so you can see through the material and make sure there are no obstructions behind it. I've never had them make airplane components but I use them for work all the time and I'd estimate $50 for run of the mill aluminum. More over, If all you need is the 2D shape cut out, the price will be lower at a waterjet/laser-specific shop rather than a full up machine shop that happens to have a waterjet/laser. I formerly operated one at our machine shop and we charged a higher rate because the waterjet was helping pay for the less-used machines.

Thanks for posting the updates, I enjoy it!

Edit: To possibly bring down the cost further for the test panel, ask if they have any material they'd charge less for. Material cost isn't the major price here, but you could save a little bit if they're trying to clear out their stock or if they could throw your job in with another one.

Re: Operation Special Cub

Prosaria, thanks for the suggestion. The radio that is in the panel design is a GTR 225, which is the certified version of the 200 (I didn't realize it had a built in intercom...bonus!). I agree with both you and Skinner that cheaper is better for this beater cub. I'd love to throw a GTR 200 in it as it offers more functionality for less $$. That said, and without showing my ass too much, can I install a non TSO'd radio in a certified airplane? I can fly around with my handheld why not a non-certified panel mount?

While we are on the subject. Any recommendations on a transponder? In two years this thing is going to be living on my farm so I'm not worried about ADS-B compatibility. Unfortunately, until then it's living in class C airspace. So, I need a transponder of some sort. I thought people would be giving the old technology away, but they still command a pretty good amount of $$$.

ASA. Thanks for the education on CNC vs. waterjet technology. In my uneducated mind everything is a CNC mill, just like every soda pop is a coke. I really like the polycarbonate idea. I'm seriously concerned with some clearance issues and that would be the ticket. I'll let you know how it goes!

Lots of opinions on that one, but the one that matters is your IA's. Also lots of non-TSO'd radios in certified planes, my previous one and my current one included.

Re: Operation Special Cub

I would go with non TSO'D no problem. Look how many kx 170B radios are out tete flying in certified planes. They don't have a TSO.
A lot of the radios out these days have built in intercoms. The Becker, garmin, icom, and I think even the Trig.
