|Thread: Looking for a cowl for my Carl Goldberg Super Chipmunk.|
I have an unused goldberg cowl for the chipmunk.- still in the raw white as delivered.
bought it for my chipmunk which had an involuntary roll into the deck when some decorative film came loose and blanked the aileron. I had a saito 90 in it - flew great - i used to just fly it to height then dive with engine on idle and listen to the whistle of the prop/plane as it passed by - a great sound.

|Thread: Forum members' new models: Let's see them.|
My Vagabond Senior is based on Bill Winter's 75" span Vagabond 1949 plan and his redesign for RC in 1981. It is scaled up by 50% to 112” span. Powered by a 500W brushless motor and 5000 4 cell Lipo.
The cerise red chiffon doped over mylar film turned out nicer than I thought it would.
Photos show the breakdown for transport and storage. Carbon rods are used as joiners for the wings and to the fuselage. The white model is my 100" span Cumulus by Ben Shershaw.
Build thread for the Vagabonds is here
Youtube videos are here. Mick Butler took the videos and more of his vintage videos can be viewed thru the links.
|Thread: Ink Jet Printing|
I used to tape a piece of transparent solarfilm to a sheet of A4 STICKY SIDE facing the printer.
I would then print a MIRROR image of the "decal" onto the sticky side.
When applied to the plane's wing surface, the printing is now protected from rain/fuel etc. and of course is the right way up.
You do have to be careful and get the taping smooth to ensure it doesnt snag in the printer.
|Thread: Balsa usa eaa biplane|
your in luck as I have the complete kit - need to unearth it from my store and scan the instructions.
will try and get to it monday. If you email me direct thru the forum, I can send the scans back to you.
|Thread: Vintage airframe coverings.|
Dope is used as the adhesive. Most models flown at vintage flyins in this country are covered with tissue or tissue lookalikes such polyspan. My Debutantes have been covered with tissue/mylar. My Vagabond is covered with doped Chiffon over Mylar. The chiffon provides the colour and the mylar reduces the dope needed to fill the weave. Both contribute to tightening and the strength. Buildlog of the Vagabond with more photos are in RCgroups here
|Thread: Majestic Major (electric) build.|
Several Majestic Major Videos here including this electric one
|Thread: Solartex alternative?|
I use the gold original - not tried the thinner version. No smell.
that looks like its the same but the impex has a convenient spout for controlling the amount used
I have been using polyester dress lining ( about £2 /running meter either 1 or 1.5 M wide.) using Impex Hi tack glue as an alternative to balsaloc. Comes in £3 handy squeeze bottle with a thin spout. Apply a thin trail and smooth flat with fingers and let dry. position lining over and use covering iron to activate glue, stretching at same time. Not as easy as solartex but miles cheaper and plenty of colours/designs from dress material shops.
google impex hi tack for online availabilty but may also be available at local dress materials shops.
Finished with 2/3 coats 50/50 dope/thinners for electric models - glows need fuel proofing.
Depending on size of model I have also used doped chiffon over mylar - both applied with impex, giving a very light but strong almost translucent covering for vintage look. The mylar reduces the amount of dope needed and also provides an airtight covering. See my 72" span Vagabond as an example

|Thread: carbon fibre push rods|
How do you fix these to carbon rods??
For some time I have been using carbon tubes - approx 1/8" dia - the inside dia is just over the standard quicklink
threaded rods dia..
I roughen and then bend the rod slightly to give a friction fit inside tube and then run cyano down inside once I have length right.
I fly vintage and load on rods not great so strength of joint more than adequate
|Thread: Binding two transmitters|
My spectrum dx6 will bind more than one model to one memory but there is no chance of me inadvertantly flying 2 models at same time as I only ever have one battery in one model at any one time.
leaving a battery in a model not flying is an unsafe practise.
As I understand 2.4 and binding, you can only bind 1 Tx to a Rx but you can bind more than 1 Rx/plane to a memory point on a Tx. The latter is particularly useful for older Tx's where there were only a few memories available - 10 on my spectrum. You do have to adjust plane trims so that Tx trims are same for both planes
|Thread: fav model of all time|
For me, it has got to be Vic Smead's Mamselle - a 38" freeflighter from 1965. In addition to building ( and still flying it) in 1972, I have built 3 off 72" and one 108" versions - the latter suffering a fatal landing-spiralling in about 3 weeks ago - jury still out on cause. The solartex covering came in handy keeping the bits in one ready made bag
Can be seen here flying in 1990

|Thread: An alternative to Balsaloc|
I have been using Impex Hi tack as a substitute for balsaloc. Easier to apply with the thin spout on the bottle- smear down flat with wet finger and leave to dry. Then apply covering and apply tacking iron to activate glue as you would with an adhesive backed covering. cost is £3/bottle but lasts longer than balsaloc as easier to apply.
|Thread: Best Plane You Have Owned|
Cannot make my mind up between my almost 30 yr old scaled up Mamselle by Vic Smeed or my new year old Vagabond by Bill Winter. Both fly a treat. See for yourself

|Thread: Model ID help please|
It looks like a david boddington bistormer with the cabane redesigned - the bistormer was 72" span and i think was for a 60 2 stroke. I flew mine on a 60 2 stroke Merco which was a bit sedate when it came to aerobatics.

|Thread: Fly with the music|
on the otherhand , you can have videos of model flying with some nice background music
|Thread: Removing solar trim|
I used to clean my solarfilm models every once in a while with thinners . Did not harm the film but it just might loosen up tthe adhesive on the trim to enable it to pull off. It should also clean up any colour left. WD40 might also do the same.
|Thread: Carbon pushrods|
I bought those carbon rods some time ago but havent used them yet as they are a bit big for my type model.
I use ordinary carbon tubes approx 1/8 dia - the inside dia is very close to the threaded wires for quick links.
I bend the wire just enough to give interference fit and then when I have right length sticking out, I wick cyano down wire into tube. As stated above, the cyano penetrates carbon and gives a good joint. I roughen wire slightly to give cyano a better key. Not pulled one out yet. !/8 rod will bend slightly on longer lengths - so need bracing along its length - usually a piece of balsa glued across fuz every 5 or 6" is sufficient.
|Thread: Southerner 60 scaled to 72|
my build log details info re motor etc - 350 W for my 72" version. Rob's 250 W motor sounds about right for the 60"
Note that I lengthened the nose and the battery is immediately below it,to get CG forward for reasonable RC flying and give me more control particularly for tip stalling. The polyhedral might be more forgiving on that.
I would also agree with KC's recommendation to build a simpler more robust model as a starter and can highly recommend the majestic major or the smaller junior 60. The video of my MM will give you an idea of what it looks like and how it flies. link here .
For vintage enthusiasts, Mick's videos have a good selection
|Thread: Which kind of models can be flown at your site?|
our site allows anything up to 7.5 kg weight limit except turbine jets - in event of crash, fire risk in forest not acceptable
so cannot vote
