Hello RC Combat flyers.

First of all as a disclaimer I am not a combat flyer, I am a pylon racer.

Anyhow I´m very interested in being able to build a very simple, quick to build plane in order to get anyone with a .40 size engine to have some weekend fun pylon racing at their fields.

Given so, I need to ask how do you build your RC Compat plane foam wings in order for not having to planked them with balsa....Is it just Pink foam a spar and tape, or are there any other secrets.

Another thing is how you do to obtain a smooth surface on your wings if they are not planked (mainly at those scale type RC Combat planes)

For a fuselage I was thinking on a PVC fuse, but is there any other better idea yoo use at your planes as fuselages it will be more than welcome.

Some pics might help as examples of what I am asking.

Any guidance will be highly appreciated.

Most combat planes in the US are built by using a hot wire to cut a foam wing core, adding spars (usually fiberglass rods, but not always, sometimes wood), and covering with tape. The tape is usually bi-directional packing tape, either just over the spars, LE and TE, or sometimes over the whole wing. Covering is usually colored packing tape, low-temp heat shrink, or vinyl. In the past, ripstop nylon was popular, and I'm sure some guys are still using it.

Most of us aren't too picky about exactly how smooth the wing is, it's going to get dented up sooner or later anyway. My scale planes are done using the same constrution as my open and SSC planes, I just use clear packing tape, then paint. Packing tape also shrinks with heat, so wrinkles that show up later can be removed.

I am a combat guy too but I use coroplast wings. for a cheap easy plane to build, check out www.spadtothebone.com there are alot of coro planes there that can be built rather fast and cheap. the DPS makes a great racer, along many of the other designs. you just cant beat a cheap, durable and fast to build plane than a SPAD

oh, yeah, totally spaced on coro construction. Hard to beat for cheap and easy. a bit vunerable to prop cuts compared to foam, and sometimes heavier depending on what wingspan you're looking for. But for a "one design" class or a set of airframe rules friendly to coro it's an excellent choice.

oddy,
If you are interested in such a plane I would be more than happy to help you out!
The Avenger has a 64 " wing ( blue ) foam core.
The fuse is made from G 10 and Basswood...this combo is very durable

I have customers in Texas who fly them with old .40 size engines.......

Thank you all very much, great help.

Once i develop the plane I´m talking about, be sure I´ll be posting some pics for your feedback.

Kind Regards.
