I recognize the model but I can't remember its name. I had one in 1954.

I remember it from along time ago like back in the early 60's Ammco or something like that comes to mind as the manufacture. I'd really be tempted to hang that one up as the escapement inside really tells it's age. When removing the escapement please take care as that is truly an antique probably worth more than the model itself. Really good find BTW.

Thanks guys for the help! the only thing that turns me away from a rudderbug is the vertical fin, size of 55", and the sheeting on the LE of wing. However, anyone could have done this to meet their own taste. The model is in really good shape and I plan on converting it to electric and adding elevator. I was even thinking about selling the escapement to help finance the conversion. It is covered with silk and will be silk on the restoration. Any suggestions will always be appreciated!

Slow and easy round the patch!!!

Some one guessed "rudderbug"...and I believe he is right....but there is one other candidate... and that is the Mambo...There was a large one and a Mini-Mambo

Rudderbug was my first answer.

Here are the results of several months of research and the gathering of opinions http://www.rcuniverse.com/forum/m_8147321/tm.htm post number 13. I have began to restore the airplane and since it is an electric conversion I will continue to post my build/restore progress and pics here. Any Ideas you have, throw them out there. Thanks Bill

Default Rudder Bug Restore and Elec. Conversion

After about a year of off and on research and gathering of opinions I have decided to restore my early 50s scratch built Rudder Bug copy but first a little RB history. The Rudder Bug was introduced in the may 1949 issue of MAN. Apparently it was never kitted and would explain the many different versions that I found when I was researching it. Every thing from sheeted and un-sheeted leading edge wings in 85",77",74",72",62",55"and 54",with and without cap strips, different shaped doors, extra doors, windows shaped triangle, square, oval, and round, a lot of individual touches. It became very popular and was finally kitted by Berkeley models around 1954 in 62 inch as the Royal Rudder Bug. In Jan 2004 it was introduced in an electric version the Rudder Bug-E in 54". My airplane was scratch built around 1952 and was scaled down to 55" with some personal touches of the builder.

First order of business was to strip the covering, take care of re-glue, any repairs, replace the fin and rudder and add elevator. I was able to get some measurements from" Skyvolt" who built the 54" electric pictured in last post. The fin the builder put on the airplane just did not have the look of a Rudder Bug.

Simibill, According to all my collected info the original Walt Good 74" RB was not kitted, the plans were introduced in May/June 1949 issue of model Airplane News. In 1954 Berkeley offered a 62" kit "The Royal Rudder Bug". About the only difference other than size was the shape of the wing where the wing attached and the shape of the side doors

Next order of business was to cut in the rear windows. rudder bugs as a rule had rear windows. The builder of my plane chose not to have them. I wanted them so I cut them to match the windows in the doors.

billmod12,


It looks like you and I have been finding some of the same places in our search for information on this classic, but apparently not-so-popular, plane. This is my winter project and I am building the 62” version from plans. I too am going to power it with an electric outrunner of a not yet determined size. I am sticking to the plans and it looks like it will be a “tank” when it’s finished. It will probably be around 3 or 4 pounds but it should be strong. It will be rudder and elevator but no ailerons. I found a blog where someone tried it with ailerons and found it to be far less than advisable even with less dihedral. I will follow the tail feather scheme of Walter’s MultiBug.

David, It seems to have been a popular model till Debolt started making the Live Wire series in 1952 and Guillows Trixter Beam and other shoulder wing craft. Mine At 55" is going to come in at 48-50 oz. The 54" later electric version comes in at 48 oz. Mine has a lot of ply in it but it is very strong. Here is a plan of the Multi-Bug if you can get anything from it. Join in with your build on here if you wish. I have been stareing at this one for about a year and it grew on me. Still working on the power source but trying to get far enough along to get a more accurate weight. As far as controls go, I will be rudder elevator. With the original 74" Bug with 18 degrees DH, Walter advised not to go past 7 degrees(1/8") rudder deflection because the turns would be to tight. My DH has been reduced to about 6.5 degrees. Be in touch!!

Default My Bug

This is just a teaser or more correctly, it is all I have done after several months of intermittent work. Some time has been spent revising the elevator control and on the nose gear. In my first post I said I was sticking to the plans but there are some deviations. In this photo you can see I am using aluminum instead of wire for the main gear and I will also have a steerable nose wheel.

David did you shorten it any or just change the design of the horizontal stab to the multi-bug? Are you going to use a multi-bug fin/rudder design as well?

Well today started out snowing at 26 degrees till we accumulated a whopping 3/4" of snow then it rose to 40 and melted so I figured I would tinker in the shop on the plane. Since last post I plugged all the holes in the nose and did a little house cleaning in the cabin. Sheeted the bottom which was originally silk because I land on sticks occasionally and in handling it is prone to getting punctured. Next step is to order more silk and dye it yellow, I will use a red/yellow scheme. Next, install servos and pushrods cover everything, paint and get a final weight and choose a power system.

billmod12,

I did shorten it aft of the wing TE because I thought the electric motor would be lighter than a .19 size glow engine. Now I’m not too sure that was necessary. The battery will be up close to the back side of the firewall and the motor mount will be adjusted forward or back for the final balance adjustment. It looks like your plane has a slightly longer nose section than the original design.

The only change to the yet-to-be-built fin/rudder will be to make the rudder a little wider.

I would like to cover mine with silk/dope but I have to try to determine if plastic film may be lighter. This is probable not the right place to try to make up for the excessive weight I have already built in.

We are expecting temps of ~30+ deg. today so I will probably not do much work on my Bug but will be out flying after some other errands.

David

Today,Tackled what I think is the worst part of the job, stripping the wing. I am kinda excited about restoring this model since it has only been covered one time with red silk and no paint. Usually when I restore an ole one it has been painted so many times that when you strip it the wood becomes stained and you have to use dark colors of silk to hide them. I have always wanted to do one with yellow silk. This one is clean enough to do that. I will do the wings and stab in yellow and maybe paint a little red trim on them. Using MEK, I had to move out doors but it was up to 40 degrees today and 5.5 hours later and a few repairs I came up with a pretty decent looking wing.

I guess when you strip every inch of something you notice things different and unusual. The RB cabin goes from square to triangular in two steps. The builder of this one laminated and formed 4 pieces of 1/16 wood to make a smoother transition in the fuselage change. The outside piece is balsa the other 3 are 1/16 plywood. I also couldn't resist putting it together to tease myself!
