Re: Cox Engine Forum Speed Contest 2018!!!

Okay, motor mounts done. All that's left is to build an airplane around it.

[Dane Martin]

Jim emailed me to check this post out. Thanks!
I skimmed through, is it 2 line only? Or can I run monoline?
And I apologize in advance everyone......

2 line only

[JPvelo]

Here's a link to control line plans with a span of 20"or less. There's everything from mouse racers and proto planes to full on stream liners if your looking for a plan to build from or inspiration to design your own.

I am officially NOW a sponsor with:
1-- $100 US(or foreign country equivalent) Cash prize to First place (evidenced by CEF popular vote)
1-- Brodak or RSM kit of choice from the 1/2 a list of kits for Second place (evidenced by CEF popular vote)((basically allocated $75)
1-- Sig MFG or Tower single quart fuel cost for any blend desired for Third place (evidenced by CEF popular vote)(( basically allocated $30))

Now that is cool!

Engine mount pretty much done, wing cut out. This will definitely need to be a clockwise flying model.

.... I really hope that this contest gains some momentum. We need a new "rules" thread........ and a new graphic (pokes Jacob  ) to draw attraction.

I'm working on it! Jim has already sent me some pictures to use for the graphic.

[roddie]

Thank you Jacob! I should have figured as such. I'm just excited about this for its inventive aspect.. and the fact that it's getting around to that time of year where modelers are starting to consider what to build over the Winter.. (at least here in my neck o' the woods! )

[pkrankow]

I have an idea kicking around.

It might not be so good as this last year I haven't flown anything and the only thing I ran at the flying field was a chainsaw...

I've flown maybe five times in the last year, if that much. I'm telling myself that will help me overcome my inverted flight instincts and fly clockwise without poking it into the ground.

I'm WAY behind either of you two... but still "jacked" to "maiden" my Bearcat..



finish my TD-powered T33 Shooting Star.. except... it has no landing-gear.. (dolly-launched) but it's still early-enough in its' stage of development.. that I could affix a wire-gear to it...??  



and maybe build a third model.. ????????????

[JPvelo]

Roddie,

It would be super simple to tie a landing gear into the engine bearers on the shooting star. Just don't over think it!!!

[KariFS]

...or maybe a tricycle gear, one wheel that keeps the nose up and another two at the rear half of the wings. Three wheels might mean more drag but it would sure look cool. The main gear could be low and the wheels small to give it the ground stance of a conventional model.

Oh and JP, about the last picture, are you sure that is the wing and not the stabilizer that thing just has to be really fast just to stay airborne

[pkrankow]

The T33 has tricycle wheels so that would be more scale. Your call.

Ha!

That's the wing, I'm designing my own but I'm using these as a guide/inspiration

[JPvelo]

My balsa "pan" is starting to take shape. I'm going to finish this model with clear epoxy finishing resin to bring out the design in the wood.

[roddie]

That's a good amount of work there Jim! Looks rugged.. and we know from experience how important that is. I like and understand the CW flight plan for your model. Maybe some of the previous speed contest entries would have faired better, set up that way?

On a side-note.. did you happen to catch the vids posted by "germanbuddy" on the Lassogeier C/L competition in Germany that was recently posted? There's some sweet "carrier" footage.. that I'm sure would interest you. It's the 2nd of two vids and begins around 03:45:00...

[roddie]

Incidentally James... the second photo/plan of your inspiration bears the name of "Bill Dean" I noticed.



I thought that was pretty cool actually!

[Mike1484]

The Peanut was a Warren Kurth design . Bill Dean most likely drew up the plan for the magazine . The original Peanut is at the AMA museum in Muncie Indiana . There were two variants , one with a wood fuselage and one with a pan as I recall . Also they used different motors as best that I can recall .

Well, I definitely have no hope of placing in this contest.  I'm entering two planes.  One will be the Dale Kirn 290 Special I built last year but still haven't flown.





An one that is a variation on Tom Jolly's Burp.

C'mon dude... don't discount your entries. I LOVE that 290 Special! I'll bet that it hops off the tarmac and boogies!

[JPvelo]

Mark,

The speed you build at I'm sure you could knock out a "Mini Speedster " type plane in one evening. Here's a link to a black widow cylinder  for $11 after shipping.

There's your race plane right there.



The Pep Talk Jim

[JPvelo]

My "Modified 290" engine mount seems like it should work, looking forward to getting a test run on this design.

[Ken Cook]

Jim, one thing I find that happens when something like this is brought to the table is that your faced with many why can't we do this questions. I in no means am suggesting any alteration of the rules. I'm just throwing this out there because I already own several of these models which don't exactly fit the criteria of the rules in regards to the wheel limit. Most speed contests suggest the 2 wheel rule. However, only a limited event demands the 2 wheel rule. In most of the racing events I have participated in, the rules state that a single wheel gear must be a of a certain size. Seeing that the majority of my planes are one wheel, the only advantage to this is less drag and that's marginal at best. So I'm asking, is a one wheel gear acceptable? If not, completely understood.
