Flite fest 23 barnstormer challenge p26

[FlyerInStyle]

The cowling shouldn't block too much airflow, it's just a ring that surrounds the engine. Air should be able to flow right through it.

hopefully. I am thinking about how to make it, and how to mount it for now.

@wilmracer you said you could take some pics of a p26 that is near you for me? I need some pics of the tailwheel on it if you could get me some pics. I cant find it on any pictures online, and my tailwheel setup just isn't right.

From the thread linked over on the RCScaleBuilder forums. The early P-26's had a fairing around the tailwheel, but later versions had a swiveling tail wheel and no fairing.

Interesting. I just wanted to know where it was mounted and if I should make it steerable. Right now it doesn’t turn at all while taxiing without a steerable tail wheel, and I don’t know if that is a scale porblem or just something of my design,

That's a scale issue. That's why the later models got rid of fairing and added a castering tailwheel. Fixed or steerable would be scale accurate depending on whether you went with an early or a late model. I would go with whichever makes flying it more fun.

Iwill probably keep it the early models as my models always have problems tracking straight on takeoff so at least this one won't have that issue. Being able to take off is better than being able to taxi. Nice to know that isn't just an issue with my design

Sorry I have not posted here, but I have decided to redesign the peashooter stronger, as I don’t like how weak the previous version was. I have a screenshot update, this time making it half master series, fro simplicity, octagonal though I may make it full master series later.

 

[FlyerInStyle]

update, I have decided to make the wingspan larger than scale, as I really need the excess lift. I am also considering ideas of where and how to mount the batts. Anyone have any ideas?

Here is the finished model of the fuselage of the version 2:

As you can see the pilots headrest part is missing, but I plan on reusing that from the previous version. The motor mount will be 3d printed and both the vert. and hor. stabs have double sided kfm airfoils. Now I am working on manually unfolding the skins, as my cad, Shapr3d cannot do that. I am thinking about trying pepakura for this though

I'm pretty sure you can unfold things on Fusion360. Give it a try.

I did, Fusion wont cooperate.

I did, Fusion wont cooperate.

I wasn't able to do it in Fusion, either. @Whit Armstrong explains how to use Exactflat to do it:

He has some videos too.

I dont want to do exactflat, my dad says it holds some viruses or something, and so I shouldnt get it... I think Ill just try it by hand for now

Here is what the plan is looking like right now:

3 out of the 7 skins are done, as you can see on the right, and everything else is drawn out. This is taking a painstakingly long time so it is being delayed somewhat. I am hoping to get theese plans done over my coming up spring break (the nest two weeks). This is getting really close tot he flitefest deadline.

I also need to finish designing the wings, as currently on the center section is in cad.

 

[FlyerInStyle]

finished p26 v2 in cad, finishing up the 2d pan is hte next step.

Anyone have anything that I should improve?

 

[FlyerInStyle]

Here are the finished plans (in sheets of 2 pieces of foam) for anyone who wants them. I decided that I will figure out ailerons when I build it, so they are not marked (I couldnt figure out if they were too big or too small, etc.) The wing needs to be mirrored

It is a massive 10 sheets of foam (without trying to compact it)!

If somebody could take a look at the plans and let me know if I forgot something that would be nice (I always forget something)

 

[FlyerInStyle]

update: no pictures, but am working on cutting out the plans and maybe will get it built by monday. Would anyone like to help me make skins? I am trash at graphic design, and frankly dont have the time to learn, so if anyone could help make this plane look amazing, I would really appreciate it!

 

[FlyerInStyle]

Here is an update, I got the plans traced on the foam, next step is cutting them out 5 sheets just for the fuselage and tail parts, four more for the wings, which I will do later.

 

[FlyerInStyle]

Just finished preparing everything for building

 

[FlyerInStyle]

Everything finished up, getting to installing electronics, and hopefully finishing up today. Since both the v1 and v2 dont fit in one photo, I showed their fuselages for a comparison. The v2's fuse is slightly smaller in height but looks more scale, but the wingspan and length is the same
