    Radford Well, consider yourself Very LUCKY- that could have been a disaster. Were ur wings bolt on, or rubber banded??.



They were bolted on with two bolts in the front and one in the rear. All three wood blocks pulled out cleanly. I installed dowels and rubber bands and flew it again today. The plane flys great but I need to install some wing struts....when I do a fast roll the bottom wing tip almost touches the top wing. That should be all this plane needs to be a steady flyer.


How many bands are you using and how are you putting them on, I was told to put the first two front to back and the next two crossed left to right and right to left corners. I had them on my first two planes (trainers) and never used them again. I'm such a pack rat that I still have bands from my last trainer ( mid 60's) LOL.

Something is wrong there. My rubber banded wings, without struts are put through violent snap and Lomslovic type tumbles. They remain firmly in place. Adding unnecessary struts is compromising performance and safety of the aircraft for appearance. Not a trade I would make. Why add drag when it isn't needed. No full size designer would do such a thing. Struts were a necessary evil for them.
Anything bolted, like the landing gear, has no give and can rip the bottom right out of the fuselage. I have seen it happen.



Yeah, something wrong for sure....I put 10 #64 rubber bands on the wing and it was still doing it. I guess I could keep adding bands until the wing collapses...or add a couple of struts.


Sounds like a broken spar, its bending outboard of the fuse!

No it's not broken. You can see what's happening by pushing up on the bottom wing tip...the wing rocks in the center stretching the rubber bands. I got the struts installed today.

Hi pd1 and HighPlains,

Thank you for the info, especially to build it light.

pd1, I have posted some more photos of the box that may help to work out when it was made. 1971 looks a good guess going by the box manufacturer on the bottom of the box. I will have a look at your build thread.

Thanks again

Peter



That's one from 1971.
I forgot the address was left off the end of the box because we were moving.

Status: offline 		Hey guys,
Today a co-worker of mine gave me his original built aeromaster from back in the 70's it has a .60 OS FSR I think he was calling it a schnerl? It says OS FSR on the engine so i figured that's what it was. Anyways the plane has not been in the air in 30 years, I am going to have to probably strip the plane of the covering and start from there, its in rough shape. My question is this plane seems like a brick when I picked it up it had to be 20lbs. I did not get a chance to weigh it but it was heavy. Is this the way they were build back then or did my co worker go overboard with some sheeting? Any way I want to rebuild it and get it airworthy seems like they are great planes. I have only flown electric but this seems like a good way to get my feet wet in the fuel line of rc. He also gave me a andrews trainer plane with a OS .25 in it. That plane has also not been in the air in 30 years. Will post some when I get the chance. Thanks for the advice in advance I am going to need some help when it comes time to get it back together.

Matt

Lighter covering is one way, and stay away from heavy paint. I suggest you take the time to read the information in this thread, as there is too much to keep repeating it.
