Me too .... damn Jboy ... I am getting as bad as you regarding buying new planes. What new plane or planes are you bringing to the field today, once the June gloom lifting later today?

Have plans with family visiting from out of town, so no flying this evening for me. My last build was a green PA Ultimate AMR, which I maidened the weekend before last. I have maybe 8 others sitting NIB waiting to be built (4 are spares, though). I can't do any builds at the moment as my workbench (aka dining room table) was cleared for visitors.

This is the last plane for a while - all the others I want are out of stock.

I cracked a few balsa pieces in the fuse of my PA Addy this past Sunday. I was inverted coming low and slow at me when the prop stopped spinning and no control whatsoever. I ran as fast as I could to catch it but it skidded onto the grass before I can get to it. The cause --- over used and loose EC3 connector which disrupted the voltage to the esc.

I just heard that the blue/black scheme planes will be available to ship from China tomorrow and the blue/red scheme planes will be available to ship from China in about a week.

I just sent an email to ask if I can change my order from a blue/red to a blue/black to hopefully get one here sooner .

If I really like the plane then I will get another kit in the blue/red scheme.

Yes, we are shipping the blue/black, a.k.a. the chess version today. Those who pre-ordered the blue/red, a.k.a., the red version will have to wait for a few more days.

Cheers,

feda

Frank - What can you tell us about the 56" model you mentioned at the other thread. Is it another full frame EPP? Any pictures you can share?

By the way, I am eagerly waiting for my red 48" EPP Extra 330 LX to ship.

The blue/red 330LX will be avalible for shipping in 1 week. Hope your waiting is worthy, hehe..

Ok, now we are discussing what kind of structure will be better and what details we should focus on for that big size EPP foamy, then our engineers will make the drawing with CAD. So there is no picture to share for now.
Usually it will take about 3 weeks before the first prototype is avalible, and one more week to test fly it. Mostly we will need the second prototype to confirm everything we found that is not so good has been revised, and then test fly again until we are satisfied.
In this stage, any idea, opinion and thought will be appreciated, they will make the kit more like what we want. So please kindly let me know what you may concern. PM me or reply here, many thanks!

Awesome - glad you asked. I don't have my WM plane yet, so you may have already incorporated some of the things I suggest.

I don't think wire landing gears will hold up well for this big a plane. Maybe carton fiber gears would be better along with a stronger mounting structure in the fuse.

Carbon fiber tube stringers (rather than a single carbon fiber backbone) would be nice to fight flexing and avoid damage during a crash or hard landing.

The 48" EPP planes I have use carbon fiber wing tubes coupled with a plywood spar going the length of the wing. That plywood spar breaks easily and results in part of the wing breaking off in a crash. A full length carbon fiber tube or a carbon fiber strip reinforced plywood spar would probably be a lot stronger. The ailerons also tear out of the foam in a crash, taking a part of the wing's trailing edge with it. It would be nice to have a balsa strip reinforcing the wing's trailing edge for the aileron hinges to bond to. For this size wing, it would probably prevent the aileron from flexing under load.

Given the size motor you will probably need for a plane this size, a thicker plywood motor mount/firewall would be good.

Lastly, I don't like the EPP layer covering the wood members underneath the canopy hatch. It makes it hard to spot if a wood member is fractured and needs fixing. It would be nice to leave them exposed. The canopy covers the whole area anyways so nothing is visible when flying.

Thanks for considering my ideas. I look forward to seeing what you have planned.

Thank you so much for so many ideas and thoughts here! it might took a long time for you to type sucn a long post. Many thanks!
I would also like to share what I was thinking when the 48in Extra was designed and some thoughts for the new 56in(maybe 55in or 57in).

Wire landing gears are OK for kits under the size of 48in, I also agree we need carbon fiber landing gears for bigger size planes.

The fuselage of 48in Extra is restrengthened by 2pcs carbon fiber tubes and a long plywood "box" as you will see, there will be at least 4pcs bigger CF tubes for the 56in. The fire wall of 48in is made of 5MM plywood, the 56in will be at least 6MM, and th structure will be different to make the mount stronger as well. The wing area of the 56in will be close to our 49in Yak55M(49in Yak55M has a really big wing), the structure of the 49in Yak has been proved to work, so the 56in should also be close to it.

For the EPP layer covering the wood members underneath the canopy hatch, what I was thinking is that I want this kit to be more coordinate in looking, not only when the canopy covers in flying, but also when it is opened to replace batterries. Let's comfort ourselves all the time.
To be honest I wasn't thinking so much if the kit crashes and how it should be repaired, (cause I always ge a new one after crash, Joking) I will think about it more for the 56in.

I can not promise every idea will be realized cause we also need to balance different needs from other friends and the needs for production as well, but I really appreciate your ideas and thoughts here.

Frank

Sounds like it will be a great plane and will have a lot of things on my wish list. Thanks for sharing.

I agree about the cf landing. It's a major complaint on other 48" epp extras

Agreed. Can't stand it on my 48" Extra.
