Help with Great Planes Super Aeromaster
 

Hello people,

I recently aquired a built Great Planes Super Aeromaster but it doesn't have the interplane struts for the wings. Can somebody please post the materails used for the struts? I would also appreciate it if someone could scan the portion of the plans showing the interplane struts.

Thank

Erwin

Just go to

and order the following:

GAROW27 12" SHAPED BASSWOOD INTERPLANE STRUTS 6 1.96

I'll check and see if I still have the plans.

I'm assuming you mean the Giant Aeromaster.

Jerry,

Sorry I forgot to mention. This is the .60size aeromaster.

I was searching for some photos and found some which does not have any interplane struts. Now I'm confused. Does the .60size Super Aeromaster have interplane struts or not?

Regards,
Erwin

lacks interplanes
 

Nope, the .60 size Super Aeromaster doesn't include interplane struts. You have to wing it :D with your own materials. This is one plane I sure wish they would update and bring out again.

I'm Building One
 

I'm currently building this plane. I'm building version 3 with 2 - 52 inch swept wings. Plane is all wooded up. I didn't go with the big round cowl. I'm about to drill the 4 holes to mount the bottom wing. Outer struts will be 1/8th inch thick ply with balsa seats on each wing. Power is ST 60 ring. Outer struts are a pain. Keep in touch. Plane is very time consumming to build however I'm not in a hurry.

ramcharger,

Since I got mine already built and I don't have a copy of the plans, I have some questions to ask:

1. What's the suggested weight?
2. What's the size of the fuel tank?

Btw, mine came with an OS 91-FS engine preinstalled. Do you think this will fly fine without the interplane struts?

A 91 Surpass should be fine. Engine recommendations are 60 to 75 2 cyc and 91 to 120 4 cyc. Control surface throws are 1/2" aileron, 3/4" elev, and 1-1/4" rudder. A 14 oz tank is shown on plans. I plan to install outer struts both for appearance and stability of the upper wing. Can't find anything on weight. Plane has a different cg for each of the 3 versions. Good Luck!!!!!

ramcharger,

Thanks for the info. I just finished test running the engine just to make sure its running. Good thing it was. Should be ready for a test flight by next weekend. Btw, I used a Dubro 14oz tank since I can't find any other comparable size tank, and it sure was a tight fit. There was only 1/16" clearance on each side of the fuse.

I have some other questions again:

1. Does the plan have any recommended right/down thrust for a FS-91 engine?
2. Where's the CG for the swept back top wing and lower wing configuration?

Erwin

Aeromaster cg
 

The cg for version 3 is 3/8 inch in front of the rear cabane wire supporting the top wing. There is no recommendeded engine offset for either 2 or 4 cycle engines, however they mention the use of Ernst plugs for up to 2 degree right offset if that is your personal preference. They are to be installed behind the engine mount. I'm using a 12 oz round Pylon tank to lay in the bulkhead craddle.
