design for the eflite ssvpp

[hillmanr2]

Alrighty then.

I got the showstopper vpp setup for my birthday (it was nice to get something). The system requires the use of the hollow shaft park 370 (44g), a s75 servo (8g) and the vpp stuff( estimate 6g). so with this in mind I will have to design a larger plane while still keeping it as light as possible. I am going to use a multiple rebuilt shockflyer yak to get things sorted out but from my experience this vpp system will make a shockflyer way to heavy.

The additional weight of the vpp should be about 32g (1.1) from my other self designed plane setup.

Since this will be a larger plane, 35"span x 11.5" cord 3mm foam I think this opens up some possibilities so my questions are:

#1 shock fuse or a box fuse (3/4 wide approx)?
#2 cf spar(s) or cf truss bracing wing?
#3 cf push rods or pull/pull

I plan to or would like to use the following
s60 servos for the surfaces s75 for vpp control
gws 6 channel (I have one)
eflite 20amp speed control

Try a center mounted prop like the euro guys!

Sorry I don't know what that is but I am curious

Like this for example "Nippel 4D" from Manuel Nübel



Here is a nice video

HOLY CRAP!!!!!!

[hillmanr2]

That plane is crazy. Crazy like a fox, hell ya I am going to design and build one. I am also going to incorporate all the other wild stuff I have seen and perhaps try out some new tricks I have dreamed up.

It's only foam!!!!

[hillmanr2]

Well I have built something. I don't have a clue what it is but it is almost done. Profile fuse. 35" x 35" x 3/4"wide.
center vpp prop.
3mm depron.
eflite 370 h
eflite showstopper vpp
730 or 900 3s
20amp esc
bla, bla

So I am now stumped, how do I put landing gear on this thing without it looking dumber ?

Forget the landing gear, just catch it in a hover

Thats what I do with my shock style planes but I am not to sure about this

[yakwrecker]

you wont need gear it will just slide on the gym floor check out the vidoe of donatas he slides his inverted and everything. I also started to design one but i have a terrible VP its the rimfire with blabes that are too big and the whole setup wieghs to much

That would work but I, unfortunately, do not posses the mad skills of Donatas. The eflite system is also big, but seems crazy powerful. I made this foamy with a 35" span due to the increased weight, it is much bigger than a shockflier.

that is some crazy $#!t
