Speed Contest

Post  modelbuilder49 on Sun Jun 03, 2018 7:25 pm

Greetings!  I apologize for my tardiness but medical issues were in charge this time!  Gentlemen, I am submitting my post for the Cox Engine Speed Contest .... albeit late and probably not eligible but I just wanted to submit it.  This is my ME-163 built from plans from Outerzone.  It is powered with a Black Widow that I've had for quite a number of years using Sig 1/2A fuel.  After 7 warmup laps, I timed the required 12 laps at 39.87 seconds or 45.13 MPH.

Man, I'm gettin' dizzy just watching it Crazy Eyes

Hey, a little more nitro to stabilize the needle setting & I reckon you'll get a much quicker time.  Get that thing cranking a little smoother and faster!  Nice flight though. Glad you stayed upright for the whole time. lol!

Speed Contest

Post  modelbuilder49 on Mon Jun 04, 2018 9:20 am

Thanks Guys!  It was a lot of fun.  Actually, I have a whole box of 1/2A's that I built, mainly because I thought the plans looked so durn kool.  Unfortunately, I just don't get all that much time to fly 'em! In this case, I was determined that I wanted to at least qualify with the "Greats" who have participated in this event  Laughing !  Heck .... somebody's gott'a be the "waterboy" of the event, eh Laughing Laughing !!  I'm just sorry medical issues prevented me from posting to this site before the 1 June deadline.  Just curious, can anyone confirm/verify the time I calculated starting after the 7th lap? Oh, to answer the question, I used an old Master Airscrew 6X3 prop.

Nice flight!

I timed you for 12 laps, starting after the 7th lap, and came up 40 seconds for 45mph?
I would appreciate someone double checking for me.

The good news is you’re the winner with the only video posted!

I’ve test run both my entries and have my reedie 95% percent done, just need to find time to fly them.

Anyone else have video yet?

James! I like your "Balsa Bullet" this would be cool scaled up with some RC gear.
Aileron / elevator and throttle.

Greetings Very Happy Very Happy !! Oh man! I feel like the biggest dummy on the planet Doh! ! I revisited the video and then rechecked my math Surprised . This time I used the NCLRA Speed Chart at NCLRA.org and you are absolutely right Doh! !! I came up with 45.13 mph Shocked ! Please forgive me for my unworthy post. I will correct it both on the YouTube post and above. I totally screwed the pooch Sad !! I must admit, I like that calculating program they have online. I guess I won't be trusting my old feeble math skills going forward.

I put a Tee Dee .049 on my Super Corsair from the first Reed Speed contest. I’m calling this my rotary intake entry. It did 57.45 mph with the reedie and skinny racing wheels that I can’t seem to find now. Curious what it can do with the new power plant.

Unloaded noted best rpm: 17,441  mid way through the flight.
That equates to 49.6 mph prop pitch speed less drag load.
6x3 prop will naturally make good thrust over a 5x3.

Good morning everyone and to all the guys out there .... Happy Father's Day!! Ordinarily I would have kept any transactions private through a p/m but I felt if would be appropriate to make this public: To Mr. FredVon, Thank you for your most generous award. The $100 prize arrived yesterday and in a public manner for all the members of this forum, I am honored to say "Thank You! You're a true standup guy"!!

I love all the various CEF contests

Over time even the engine of the month has lost momentum

My desire with real prizes was max participation so sad it fell flat

Same with Bernie's news letter series...always a great read

The is absolutely the best community at CEF of any web forum I attend... I Love This Forum!

Congrats to James Catrer !

Fred that was mighty kind of you to offer prizes to the folks. Thumbs Up

When I was a youngster building balsa profile planes went fast. I could have it built in
one evening ready for paint the next day, very simple easy to do for all age levels.

I had built this one in a weekend here there for a few hours.
3.54oz with a TD .020 has throttle sleeve adjustment to slow fly on
calm days, was going to add a spring at some point for throttle
control with a third line / never did.





This could be blown up for 1/2A easy enough or a 3ch RC / 24" span using the TD .020.

You're a true gentleman Fred, besides being extremely generous. $100 affraid
I understand your disappointment. We seem to end up with a similar decline in enthusiasm with most forum projects or competitions. It was the big thing to enter the Tach Race a couple of years ago, but that fell flat. The scale Reed Speed competition promised to be exciting, but hardly any of the planes built for it ever ended up taking to the air. I recall up to a dozen builds going on with everyone excitedly keeping track, but that fell flat. The current speed contest was pretty simple with less rules etc. Did people just lose track of the time or was it all just too hard?

Yeah he is. When I was mourning the wreckage of my flagship stunter in the late Fall of 2016, and hopelessly trying to salvage the wing from a pile of splinters, the doorbell rang. It was the mail-lady with a 4' long box. Inside was a complete Twister wing kit from model-maker Walter Umland, with Fred's return address on it. He must've felt my pain. I hope he felt my glee when that box arrived. After the rebuild, the Tazmanian Twister was better than before the wreck, and is still today, the current flagship of my stunt fleet.

I am just a full blown Pay it forward guy...I need the karma

When I was a poor kid I can not even remember all the neighbor hood moms and dads that keep me occupied and productive while my dad was away at some war

Then as I came back to the HAM hobby and model airplanes...after having done well/OK in my careers...too many internet friends helped me immensely

As I age and get more and more infirm....I already know what my Children want for my STUFF

so the vast expanse of all the other stuff will slowly be distributed to forum buddies that have some need

Funny thing back when Rusty boinked his plane I hit up Walt Umland desiring to replace the wing just as Walt was recovering from some bad ailment....he pushed my request to the front of the line and did the job of creating the wing kit for Rustly even tho he was not back in shape...Why? Because he appreciated Rustly's hard work video documenting the JIG and alignment tools Walt had for sale

Point really is this hobby community is unlike my HAM Radio or GUN nut or wood working community hobbies....many more givers than takers

OH and I do need all the Karma I can get

Remember the enthusiast kid from Noosa Queensland AU? Just a wee one...I sent him a bunch of stuff... now a teen age young man I imagine he is deep in school, girls and cars... BUT I am confident when he is older he will revisit his youth as so many of we have... hopefully find the Cox engines...find some kits and fondly remember some Old Dude in Texas named Phred

Fred, I would've liked to participate. I have a few 1/2A speed planes and I really don't need to build anymore. Unfortunately, they didn't meet the criteria of the rules. I wasn't going to alter them to do so. From the sidelines, I think the time from rules to posting vids were far too great. I do realize why things were extended, it's just that it causes procrastination. I for one am very good at it when the opportunity arrives. This creates a stale situation. I see it in my club ALL THE TIME. The models get started, they begin looking like something then fizzle out.

We have a 1/2A day at our club which the keepers of the cheese try to arrange every yr. Every yr they screw it up because of their poor planning and lack of 1/2A knowledge. We've had it in the dead of winter, the hottest of summer, not to mention windy windy days where you can't even fly a Ringmaster. So I set a date and if you can't make it, well there's always another time.
