Test, Test........this is just to see if I am getting thru........sent a response earlier, but did not get posted........Rich.

....ok, seems to be working now..........Jeff, the rims were designed by me on AutoCad from original Cessna drawings supplied to the AAF and printed in their maintenance manual..........there were built for me by a friend who was a self employed machine's.......the rims and back plates were made on a lathe.....the five openings that form the spokes were done on a standard mill.......he even installed ball bearings......they are so well balanced that when you spin them, they will continue to spin for over a minute.......He built these a long time ago and is no longer in that business......He is now a professional photographer .......but, i do have the original AAF drawings and the AutoCad drawings that I created, so if you are interested in having them machined, then I will gladly send copies of what I have..

Rich,
Yes please do send the wheel drawings. I have a buddy that can get them 3d printed. They have been doing some testing with 40 pounds WW2 fighter type planes and the wheels are holding up. Not as good as machined aluminum, but WAY more economical!
My email is [email protected]
Thanks!

Ok Jeff, I will gather what I have, make copies and let you know when they are ready to send...

Rich - Really enjoyed your soap box oratory skills . I would vote for you for President especially since my guy Kasich is not getting any legs in the campaign. Glad God gave us both a second chance to enjoy this hobby and actually building our models. Stay safe and Stay well. Chic

Thanks for the nice complement Chic.........I do have a problem with type-o's ......so I proof read several times and still make mistakes.........that's why it's better to have someone else do the proof reading because they can see the mistakes that I keep missing..........I live alone except for my Cat, she likes to walk all over the keyboard..........and knows nothing about proof reading.........and, thanks for your vote for President.........I am very worried and uneasy about the possible outcome.......like you said, I hope we can still enjoy our hobby, and continue to fly without Government regulations.

Hi Rich,
Glad to see that you are returned to this thread and back with the build. Looking forward to seeing your progress and before long the completed model.

My project was stalled due to work and a house move. Have now moved again but once I have my workshop sorted I will be able to start the build. I have the plans, cut parts, retracts and am nearly ready to go. Still trying to decide between glow and electric power. Head says electric but the heart says glow. (2 Saito radials).
I also would be interested in 2 engine kits (if you can manage to mould any more) and if you can ship to Europe. Let me know what you feel on this. Can send payment to you via PayPal.

Really happy that this thread is alive and kicking again. Watching with interest.

Hello David!!!!.........great to hear from you!!.........Good to hear that you have settled into your home and putting the shop back in order.....I am also rebuilding my shop because I have purchased some new equipment and need more space........I am trying to speed that along now that I have been able to return from my setbacks.........so, it sounds like you have almost everything you need to get a good start......now, to the type of power used on the Bobcat.........nothing but a multi cylinder four cycle engine can reproduce the sweet sound of of those L-4M"s ......especially at idle....... But, don't get me wrong, the electric motor has found its place in the model world......I too have them on non scale models........I guess you could place a playing card in the path of the propeller, so it will produce sound, like the ole days when we were kids and attached a playing card to the chain stay with a wooden clothes pin to produce the sound of a motorcycle.......True, the electric way is the least expensive by far......Last time I checked the Saito three cylinder's were going for about $700 ea......quite an investment........But, I paid around $600 for two OS 160 twins.......so, not much difference........but I love the sound of both at idle.......Also David, do you have the vacuumed formed canopy?...............I think it is still available thru Balsa USA.............and finally, I will include you on my expanding list of engine castings.........looks like I need to make more molds to keep up..............."Cheers"........rich..

David......go to page 26 thru 29......threads #640 thru #704.........E Couch from Richland Texas built the Don Smith as an electric.......good info and photos of it in flight........I know you will enjoy the read..........Rich.

rhsmrt50

David, I talked with Ed Couch this morning and asked him to come back to our thread.............he said he would be glad to.......He said that there is a sound module that will replicate the Radial engine........I think he said it can also reproduce the sound of twins........he said it was loud enough to be heard in flight..........I built a Dumas 1930 Chris Craft triple cockpit runabout back in 1994..........it was electric powered, but did not sound anything like the original Grey Marine engine with duel exhaust..........But, I discovered that even way back then the engine sound module was available...........the one I purchased and installed could be programmed to sound like a diesel or gas engine......it came with a small radio speaker which worked well up close.......but could not be heard from a distance......Ed said they do not use the ole style paper coned speaker like I had on the boat twenty years ago.......it is far better.........so, stay tuned, ......Ed said he can satisfy your brain's desire for the electric and your heart pounding love of those beautiful Jacobs raspy sound.........Rich.

Hi There Jeff..........I have found my cad drawings with all the dimension's necessary to reproduce the rims........also, a copy of the real rim as viewed looking at the profile from front to back, or should I say the thickness instead of the outboard to inboard view.........the rims are conical shaped from the hub inward and curve up to the rim edge........the process was done one step at a time on a standard mill, each cut required a new setting, which too a long time to complete........but, with these same dimensions they can be programmed on a CNC Mil in a matter of minutes.........we did not have one way back then........in the old days.....if you know what I mean..........Jeff, I would rather send these copies thru USPS, simply because they have such small text....and.the quality will be better, so if you have a physical address, like a po box or other.......you can send to my email [email protected].

....Well in the meantime..........how about some more "eye candy"..........

Ed Couch

Richard contacted me this morning on the question of electric power of the Cessna T-50 or in my case the JR-1 (I'm Navy). I just put about two paragraphs together and the dang thread blew it away so we will try things again. Presently I have four multi-motored not engines large aircraft flying and that alone says that electrics work. Take a look at You Tube and watch and notice the number of aircraft attrited due to engine failure on takeoff or during the flight especially around turning final. One thing that electrics give you is piece of mind that my motor will be working when I need them. That is not there on gas or fuel engines. I hear all the time is "I hate not having the engine noise I am used to. Are you saying the weed eater motor you are running sounds like a growling P and W, come on who are we kidding. I use a couple of RC Sound systems in a couple of vehicles including the JR-1 and when the vehicle (and it does) calls contact and the two motors start to grind and spit and sputter for about a minute the only thing missing is the smoke and damned if he has not come up with that as well. Throttle is advanced after the motors have settled down and away you go. The four speaker system puts out over 110 db in power and will run you out of the shop. Does it work in the air, yes it does. Now we have the sound and reliability you need to pull the illusion off of a honest to god flying scale vehicle. My earlier post outline the systems and operation of the electric Bomber. Any questions I will be glad to help answer. The Bobcat was and is a joy to fly and my Gray Lady or Sweet Caroline is just a hoot and a beautiful addition to my fleet.

Thanks Ed for your input, great wright-up!! ........so, there's the info.......decision time.........Ed can also let you know what motors that he uses and the correct brand of propeller that works and sounds best to further enhance the sound and performance............Rich.

Hey Rich! Glad to see you are back at it! We haven't talked in a while...suppose we should catch up on the phone one of these days! Trust you are doing OK and that prop vs. thumb incident hasn't impacted your building skills to any extent!

.......Beautiful......no doubt "Ole #12" as we called her........NC-59188 was featured in the July 1987 issue of AOPA PILOT .....Cover and center fold with seven pages, owned by the Mathlers at the time..........this was the very first piece of reference material that I required for my build......it was given to me by a fellow employee when he heard that I was building a UC-78..........A good friend of mine who goes by "Murphy" on this thread, was fortunate enough to go up in Ole #12..........Tell me me more about finished project......engines, radio, details.....etc..........Rich.
