RE: ***CUB BROTHERHOOD***
Question for you Fresno and whom ever would liketo chime in.

How can I acheieve that as the manual warns aganist running the engine without the 2 piece lock nut in place .The spinner will not fit with both nuts in place asthe shaft is not long enough.
Thanks

I found a low profile jamb nut at my local hardware store for mine. Never had any issues. It really doesn't look all that bad either. You can see it, but it doesn't stand out. Good luck. Steve.

RE: ***CUB BROTHERHOOD***
Not sure I undesratnd what a jamb nut is, do u have a pic?
I placed a question to OS customer support and their answer was to go ahead and use the spinner prop nut instead of the lock nut. That goes against their reccomendations..

Later tonight I should be able to send a pic. If you ask them for a jam nut they should know what it is. It's just a nut that you use together with another nut to lock it together. It took going to a couple of places, but I found it at true value. It's about 3/16 to 1/4 inch thick if I remember right.

Props4ever,
I hope you didn't think I was digging at your skills as I followed your Connie build off and on for a while and you did a magnificent job there. I just think in this case you are a glutten for punishment and believe me I have been there too. Try building from Pepino plans sometime. Worst plans I have ever seen in my life.
The Cub will be an adventure to repair but I am sure it will be fine in the end.

Hey Rafeeki, it sounds like your pretty much covered. Steve's advice sounds... uh... sound. Besides that, I don't think you wanna ask me since my gas experience is, well, pretty much nonexistent. I've got one nitro plane.

RE: ***CUB BROTHERHOOD***
As much as difficult it looked and ugly, that much easy it was to remove it!. I managed to take off whole tailplane as complete unit and then separated fin from stabilizer and stabilizer from elevators.
First I had to cut off cap fairing on the tailplane between horizontal stabilizer and the vertical fin. Then heat gun was applied to soften up the old epoxy, while it was heating I used combo of hobby knife with blade #11 and kitchen knife to score at the joints length wise. In total it took 1hr to do both side before tailplane was split from the fuselage longerons.
Once stab and fin were off the fuselage, I took some time to clean the fuselage section under the stabilizer but using heat to take off off epoxy and taking of all the access wood that shouldn't been there at the first place. These piece were used to make strength between upper and lower longerons by joining them, they should be done as truss frame structure.

Thanks fo your help Steve.
I got myself a jam nut from Lowes and did some research on line. This link tells a lot about the use of a jam nut with video clips.

Line drawing made to make newer balsa and ply stabilizer.
Leading edge will be made with laminating 3 strips if 1/8" x 1/4'' x 43" with yellow premium wood glue.
Trailing edge is 5/8" x 1/4" x 38.75", this will be made from plywood.
Truss structure will be made from 1/4" x 1/4" balsa sticks...
Going to make both elevators, fin and rudder's drawing also.

Props: Years ago I did a similar re-build on a Skybolt and it was a really fun project too. You are doing a great job and having fun in the process. Being able to do this kind of stuff is what makes our hobby truly a fun one. Once the rebuild is done the flying ain't bad either! Keep up the good work, its really fun to watch how it progressing.
Thanks for sharing!

RE: ***CUB BROTHERHOOD***
Thanks Rocky, its great to see guys on here have done these sort of rebuilds/restorations in past to fully appreciate what I'm doing here.
It's for sure not everybody's cup of tea n even certain builder can't understand on other site I'm regular on too.
Yes it's very enjoyable and comfortable project to do. Its nice, scale and easy one, for me, it's like, ya what the heck, I'll do it from project's perspective....Hopefully by the end of weekend it should be all together and reassembled once again...(Tailplane)

RE: ***CUB BROTHERHOOD***
Props your rebuild reminds me of an old Monogram Cub I found in an attick of a home restoration I was doing. It was made somewhere around 1960, according to the dating on the drone diesel engine anyway. I did the same as you, rebuilt the airframe, changed from CL to RC. Spent a good bit of time on it mostly because of all the deisel oil saturation of the wood. Not easy to get cleaned out. Recovered it in tissue and dope, the engine still ran so no work there. Flew it for a couple seasons and then one day one of our old CL members saw it. He made me an offer I could not refuse. Last I heard it was still as I finished it.

RE: ***CUB BROTHERHOOD***
I'm currently working on a .90 sized SkyRaider that somebody framed the fuselage up and did the wing - its 78 inches - and then apparently lost interest. Lord only knows how long it sat around in what appears to be a pretty unprotected place - it had lots of discolored wood and "Hangar Rash" - and then it ended up at a hobby shop where it hung in the rafters of their garage for a couple of years. A pal of mine was at the shop when the owner was in the process of throwing it into the dumpster. My pal bought it for 5 bucks and brought it to our r/c club meeting and asked what we other club members thought it was. I checked it over and while it was in rough shape it was straight and looked like it was worth saving so I bought it and am now in the process of breathing life back into it. So far I have nearly finished sheeting the fuse - I bought a set of SkyRaider plans from a fellow on RCU for 10 bucks so I know where Global recommended things be put and am having fun getting this nearly beyond rescue, partially completed model into flight-ready status. When I get it done I'm gonna name the thing Lazarus because it truly came back from the dead. Meanwhile, I'm having a hoot getting it to look like a SkyRaider. It appears somebody bought some plans and ran out of steam on the project - its a little bit bigger than the Global model - what workmanship there was - was done well but a lot of the dimensions on the sheeting attachments were all wrong so I'm doing a lot of laminating and no doubt there will be a LOT of sanding involved to get it right but heck, having something to work on and occupy our time is a wonderful thing. So, keep at it Props, its looking good!

RE: ***CUB BROTHERHOOD***
I am not sure this is the rite spot to ask this but here goes.. I am building a BUSA 1/4 J3 Cub and I am thinking about putting a set of the pre made struts that Hanger 9 puts on there Cubs.. I need a measurement from the center of the attachment bolt hole on the top , to the bottom of the strut where the adjustment bolt comes out of the strut.. If anybody has one of these that they could measure for me it would be greatly appreciated...This would be on the front strut... I have the PA18 and I just wondered if the J3 's might be a bit longer...

Wow Rocky, you also reminded on a Skyraider that I had many many years ago, that turned out to be a Global Models Skyraider and It also went through complete ground up restoration. When it was done, it was more then a brand new model could be. Had ST75 or 90 on it, can't remember the engine type but that plane flew really well till it was sold.....hey I would like to see couple of ur model's pics if you have them. Sure its Cub thread but these restorations are very similar to each other and I doubt Cubman will mind it.

Hi Guys: my skyraider thread can be found at this forum A-1 SKYRAIDER MODEL INFO NEEDED. -That'll show you what it looked like when I first started on it. It was pretty pitiful looking. I will post more pics there by next week. Thanks for the interest.

RE: ***CUB BROTHERHOOD***
Stab's build is about to start. Placed a white foam board on the building table for pins to hold in place. Drawing was covered with wax paper first, then all the pins were placed on the inner line of the leading edge curve. Leading edge will be made with Windex soaked balsa strips of 1/8" x 3/8" x needed length by laminating 3 of these together.
After the laminated strips cure fully, then center frame vertical strips will be added following with trailing edge strip to partially complete the structure of the stabilizer. After this is build, then truss structure will be added inside the frame of the stabilizer to give strength to it..
Actual build will start tomorrow as I'm out of 1/8" sheet to make strips for leading edge today.
Cub will be powered with Fuji 64cc engine with electronic ignition, engine will arrive in next few days. I'm looking to buy 20 x 6 prop for it, would this be good choice or 22" will be better?

RE: ***CUB BROTHERHOOD***
Finally tonight new leading edge is formed, presently 3rd strip is curing the lamination process. Pins are holding the shape of the leading in accordance with the drawing I made.
Love this process to make the curved leading edges. Windex did it's job beautifully and for this process, I want to say thanks to my friend Tallone66 aka Derrick on here, this was his suggestion to build it this way otherwise I have another method to make it.
Tomorrow morning I will take off many of the pins, to sand and shape the ends of this and then glue new trailing edge to the leading edge. I accidently bought 3/4" wide strip for making the trailing edge instead of 5/8", I doubt being 1/8" wider will make any difference.
I will post pictures from first strip laid down till last one laminated.
