Ken, I dont really know.... I thought about maybe building a Hawker Hurricane.... too many Spits already .

I like the Harvard but the double dihedral breaks would put me off.

There loads of WW2 type rarely seen....P63 KingCobra would be nice for instance

What did you reckon on the BugetRC plane's depron fus side stiffeners?

Dekan,

You caught me! I did not notice the Depron sides. I saw the EPP fuselage, wing , and tail, and just assumed it was all EPP. It is a very good idea since these are not really slow flyers. If they were EPP you might get some flutter at high speed. That is probably what happened to them in development.

I like your choices of aircraft. Rarity is what I liked about the P-64, I never even heard of it before, let alone seen it modeled.

Some already awesome plans out there

Here are some plans by one of our brothers in the land down under.

http://www.rcgroups.com/forums/showthread.php?t=523981

Take a look. His are primarily AET setups, but they are around 28" which works out very near the 150 sq. in. parameter.

$10 'bout 1/2 way down this page http://www.strongrcmotors.com/Motors.htm

Don't forget to select your shipping from the shipping page before checkout. The $3 padded envelope shipping will get it to any US48 address.

Ken, you always seem to create or find something I just can't take my eyes off of. Nice job finding that thread. I luv the planes featured there.

Once summer kicks in & the household gets through the recent financial CRUNCH, we will all definately have a goof fun fly combat session.

Quick look at the P-64

Started this in Sketchup, but think I like TurboCAD much better.

Ken,
Are we going to 3 servo's?
EDIT: OH, I see no rudder, so is it AET?

I like it Ken.
Is this a version of an actual warbird? If this was your design, how do you go about figuring where the CG needs to be?. I cant remember where but I remember the mac calculator being used to figure a CG givin certain measurements of the wing.

I had my Street Fighter in the air this morning but with the little IPS & a 2s lipo, it didn't have enough for the slight breeze that was out. It would just do that "Blu Baby" hover I saw this cool pilot doing a while back.

Will you be doing a cad version of the same plane? What motor do you think you would put on it. Oh yeah, & what is the ws on the P-64?

I'm thinking that I will need to move the cg back on the SF to fatten up the nose weight to get it to plane out if I will continue using the IPS set up.

Your thoughts?

Jimmy

Jimmy,
To increase flight speed you need to increase power or reduce drag. One way is to "clip" the wings, or just make the whole plane smaller.

Moving the CG reward will mostly just make it less pitch stable.

Hello

I have a Budget RC ME109 & P47 these were my 1st time building and it was fairly easy. I only have one problem now that is TX settings(Hitec Eclipse) i need to decrease the sensitivity of the ailerons i lowered the end points on the ailerons because it rolls really fast. So would the correct way be adding expo or D/R I'm not to good at radio programming yet.

Actually, I had already decided to throw the 1300 kv BW on it since asking. Thought maybe the IPS would do it since it was from a 7 oz Lite Stik. Didn't really take into consideration the substantially different wing areas & ws's between the 2 planes. Otherwise I don't want to make the plane any smaller.
Can't wait to try this guy out with the BW.

hey guys, is it critical to have the motor right on center of the fuse vert/horz cross? I am putting the BW 1300 on the SF and would like to do so w/o changing firewalls. but there is a hole from the orig IPS set up that will make me mount the motor slightly higher than center. would that be ok?

How slight is slightly? 1/16 won't make much difference, but a quarter inch may. Can you just rotate the motor mount around the original centerline? drill 4 new holes?
