Default Great Planes 40 size float kit - HELP!!!!! NOW WITH PICS

So, I've bought this kit and I'm trying to put it together but the main formers don't seem to fit. If anybody has built these floats please help me out.

I had the same problem with the 60 size. You can use the formers as is and the sides and top will be kind of "wasp waisted", or as I did, make the sides straight and fill the gaps at the side of the formers with scrap wood. Either way the floats will work fine.

The main problem with the GP floats is weight. I covered the top and sides with UltraCote and painted the bottom with finishing resin and they still came out heavy. If you glass them they will weigh more than your airplane.

Ok, So, here we have the overall view of what I have done. As you can see the rear spar is way above EF.

The spar is all the way down into the notch on C. C however doesn’t even fit in its place.

It looks like your formers aren't installed in the right place. I think I see the right former lying on your bench. replace C with the one on the table. Looks like C goes between the larger formers.

Fergy. What you see is the C former for the second float.

I'm looking at my plans and it looks like from front to back, the order of the formers is B, C, D, E-F, G, H. You have the order wrong in your pic.

Fergy. Could be, but in the instruction book, for the 40 size floats it says to only use formers C,D,E, and G. In a previous step you gluesd F to E. When all is lined up on the spar, there is only room for 4 spar's. G being the smallest, so its to the aft back of the float because that is the smallest part of the float, then I have C (could be wrong), then EF, then D. D is larger than C, so it can't goto the back. EF has to be the center one and well, now I'm just confused [>:]

Try moving C to the slotted position between EF and D. That will allow you to lower the spar to the stepped slot on F.

Looking at this picture of the built float:



it sure looks like you got the formers out of sequence somehow. That open slot between EF and D is there for a reason. What? If you move C to that slot, then you will have an open slot between G and EF. Why does there appear to be an unused slot one way or the other?

hmmm, I dunno man. I'm starting to think that the instructions are useless. I've emailed Great Hobbies about it and sent them the pics above. They said they will be contacting me on Monday. Perhaps I would be wise to let it lie for a bit.

So, this kit comes only with an instruction manual? No plans/blueprints? That's rather rude!

Kmot: Thats correct. It really shouldn't be difficult to build, its very basic to be honest, but if things don't fit, well.

Anyway, they've discontinued the kit. Maybe there revamping it.

In any case the picture in KMOT's post shows a major problem that has been in the Great Pain's literature from the beginning: The incidence of the floats is WRONG. The floats should be LEVEL in this photo. I don't know how a GP Cub EVER gets off the water with the floats like this, forcing the nose down. I think reversing the front gear legs and the rear struts would fix it.

I got my instruction manual out and the correct sequence is, front to back, A, B, C, D, E, F, G, H. From your picture you have "C" in the wrong position. There are only 2 formers with cutouts to fit over the oval mounting plates. Start with those over the oval plates. EF is OK.

I looked at your pics again and you have G at the aft end. It should be H. I think step 3 confused you. It says to "trial fit" C,D,E, and G. That doesn't mean the others are not used. Place them in the correct order and you'll be OK........Seaplane

Seaplane wins the prize, and I..... am an obvious dumbass.

Ya, I got confused on the instructions there and thought you were to only use the 4 formers. Thanks for all the replies. I do appreciate it.

As I previously stated...

...and the correct sequence is, front to back, A, B, C, D, E, F, G, H.

I built the 60 size. But I believe alphabetical order still applies for the 40...
