7up:

Thanks for the great plans.

Dave Gettman-

 

Grabbed a copy, thanks for posting.

 

Thank you Buk I hope to repay the favor as I am cutting my teeth in SU

 

I cut one of these out of blue FFF and it came out nice. Test fitting, the wing span seems a little short, but what do I know. Do you recommend a pusher motor for this thing? Oh, I took the liberty to cut some fold lines (five of them) in each wing to make them bend a little easier. I'll just betcha this thing will fly as soon as we sort out the CG. Nice job and a neat looking little aircraft. Thanks.

Mr. 7UP...completed and flew the Jeep-O-Plane. First off, want to say this little plane is a winner! I was pretty hurried to get it together for a test run so I am afraid this particular build is not very pretty. I used blue FFF for most of the plane but used white Depron for the two wings. I also cut some fold lines on the bottom of the wings to help make the airfoil. I used a 20-20L Hacker clone as a pusher motor with a 9" slo-flyer prop. The plane tended to be a little tail heavy so I paralleled two 1300mah 3S lipos in the nose and it balanced fine about 3 1/3 back from the total distance between the upper wing LE and lower wing TE. That comes out to around 4" back from the LE. Plane climbs out well and cruises well and 1/2 throttle and will fly forever (I made five flights this morning) on the two battery setup. The wings tend to fold a little but in my mind that creates dihedral, so what the heck. I suppose a carbon rod could be slid in there to prevent breakage. Now that I know how great this little plane flies, I can build another a do a nicer job. I am thinking it needs (maybe four) doll baby carriage wheels, but I am not sure. I have attached a few photos, just so you can see what I have done so far. Oh...the window posts up front are all pretty weak and easy to snap so maybe a little carbon rod or bamboo skewer behind them woud help. Thanks for this great design. It is a real attention getter in the air! Servos are 9gm - 1 for both rudders and 1 for elevator (mounted on horiz stab). Going to add ailerons to lower wing...

7up - Earlier this evening I was looking this little aircraft over and wondered what it would take to convert it to a float plane. As it is constructed, it would not take too much. The AUW is a little high for that application. Maybe it would sink towards the nose. I already know it would great as it is to take off from snow. The prop is plenty high and the bottom of the fuse looks like a snowboard so it will be good. I also forgot to mention (and it is probably not necessary) that because the fuse is so wide, lateral balance proved to be critical to flying nicely. With two batteries parallel wired, I simply placed on on either side in the nose. When I had them both together the plane wanted to go left. This is a totally fun plane to fly and to see flying. Something about it just makes everyone smile. I am going to put it through its paces again tomorrow morning and then I am going to cut out a new one and try to do a neater job of building. Maybe I can get a short video with my camera. If so I will share it.

Does anyone have a proper video of this bad boy?

 

Thanks buddy, I'm actually in the process of building one, I have printed the tiled plan on A3 size paper which makes a fairly big Jeep-O-Plane on RCG thread...

I will update my build in here if it is ok.

Can I have some inside info such as motor placement... Is it straight mount or is there any up or down incidence?

Does it absolutely require ailerons or will it fly nicely enough on rudder/elevator config?
If it does require ailerons, does it need to have 4 ailerons or only upper wing ailerons are enough?

If I need to PM Chuck about these I'll do no worries but I think it is nice to be on the open thread so anyone can see.

Cheers.

 

I think if covered with clear tape on the bottom fuselage it could easily belly take off too so I'm not going to do any LG on it.

Once I fly mine successfully I may do a water proof bottom fuselage for water take off as I have great Golf pound here in my area, as a matter of fact I might have one of the best flying area as my accomodation is surrounded with a huge Golf Course!

So a stepped bottom fuse and additional floatters on the bottom wing might work fine.

This mods to be based on the Polaris style.

 

I don't know what happened to my previous answer... it just vanished from the thread... It was quite long too lololol

 

Anyway I was basically saying that I was to stich my plan tonight to show the difference in size between my print and the original size of the tiled plan. Basically twice bigger!

I will also mount my motor straight and see if it need some incidence to it but I guess it will work out fine.

My idea is to build that ring around the prop so it look like the original with additional flat CF spar for strength.

I will also open the back panel where the motor is mounted and stiffen it either with wooden steerer use in take away coffee shop or use bbq skewers, that way it will allow the airflow to hit the bottom part of the prop as well.

This is a very exciting build and I'm really looking forwad to have it airborn.

I will be using one servo for both rudders and one servo for the elevator. No intention to place any ailerons right now, They might be necessary but can't tell right now till I maiden the plane.

So as I was saying a geared motor with a 9x6 prop, 1000 to 1300 mAh battery and 2 regular nylon geared 9gr servos will be my choice of electronics.

Will post some update later on today.

 

Well let us see how it goes with the normal config first and then I'll move on to some water mods.

I found sometimes this morning to stich my plan as Friday is our day off over here. The picture attached show you the difference in size between the Tile plan printed on A4 size paper versus A3 size paper.

On the A4 size I end up with a 29.5 inches wing span while on the A3 I'm having a 42.5 inches wing span. The fuse is huge on the A3 size, like more then double! This is going to be fun for sure!

Yep it is indeed, Thanks. Go on and Google Al Hamra Village, that is in Ras Al Khaimah/UAE.

It has been my flying field for the past 2 years.

Here is a link to an areal video I made if you are interested: http://youtu.be/5bVQLRO8GjE

 

But lets no pollute this thread with irrelevant stuff... I'll be cuting my different templates tonight and hopefully have some parts cut out...

More to come soon.

 

Oh by the way this is going to be my pilot... Thought would be cool to have a freak out Homer in the cockpit!
