Cox Profile Scale Reed Speed
« on: May 25, 2014, 08:18:19 PM »
Hello all,
I received the OK from Robert to post an event were doing over on the Cox Engine Forum. It's our second running of Profile Scale Reed Speed and it's exactly what it sounds like. Profile scale planes with cox reed valve engines in a speed contest.
 Here's a couple of examples of the planes flown in the first event:


 
We had about fourteen planes built last time. If you want to participate its open to all cox engine forum members. You have until the end of November to get a flight in.
 
Here is a link to the rules if you want to participate:
http://www.coxengineforum.com/t5898-cef-profile-scale-reed-speed-rules

This is the discussion thread for the November running:
http://www.coxengineforum.com/t6801-reed-speed-version-20-nitro-november

And the results from the first event:
http://www.coxengineforum.com/t6798-reed-speed-results

Thanks for reading and I hope you participate!

The old Thermal Hopper is a reed engine, can I use that? VD~

Larry,
Yes, any cox reed valve. The only restriction is no TDs' modified to take a reed.

  Very cool! Search the forums here and there may be something about our Golden Age Races we have had here in St. Louis for many years. Models must be reed engine powered, replicas of Thompson Trophy Racers, 18 inch span and a few other rules, but we also allow full fuselage models. Frank Beatty has had several of his designs, profile and full fuselage, published in Flying Models and Model Aviation. Common set of lines that everyone uses, club provided fuel and only Cox 5-3 grey prop allowed. Lots of fun and challenging!

Dan,
I have a copy of model aviation with a Bonzo plan from that event. Sounds like your club has some members that would be competetive in the Reed Speed event!

My only question on the rules is that landing gear may be left off of planes whose full scale counterparts had retractable gear. If speed is the goal why would anyone build anything else? IMHO make LG mandatory, scale location optional. OBTW: Sea Fury and Corsair look great!  8)

Not everyone has a hard surface to fly from; and even if you hand launch grass landings with a gear that small are not pretty.
 Thanks, the Corsair is mine. I'm going to build a aerodynamically cleaner version for this go 'round.

That was a fun contest. Like most of the other guys, I knew nothing of speed planes before you started this. I bet the next go-round will see some hotter action.

The P-39 hasn't flown yet. We had a relatively short flight window the first time around. That's why it's open from now until November  30th this time.

The planes look GREAT.  The only problem is the dwindling supply of healthy reed valve engines.  I had several, but depleted them in numerous Walt Musciano hollow log events.

I think dispensing with the undercarriage and hand launching over grass might be the way to go, for several good reasons.

I know it blows the 1/2A concept, but the OS Max LA15 would be a viable alternative.  They are less expensive than the current production run of "Cox" 049's.

Where are these selling for below the price of an .049?  I might have to get one of those.

How are you launching models that don't have landing gear? Dolly? Or is hand launching feasible?
I built a Blue Pants as a kid. Wish I still had it. Might even learn to fly it.

I've not flown the staggerwing yet but I've hand launched the corsair at the beginning of the thread. I was surprised at how well it worked.

Hi Jim!  Not intending to be an irritant, I understand the photography requirements as written for the flight portion of the contest but does one need to document the build like a couple of the events being hosted on RCGroups?  Thanks for your patience!

Jim,
 While it's not necessary to document most people do. It can lead to some lively conversation and it lets me know how many potential participants there are.
 Thanks for asking, I hope you join in the fun!

Well, I guess congratulations are in order!!  CONGRATULATIONS :D !!  As for posting, okee dokee .... while I was waiting for your response I built and completed three planes for the event.  I'm hoping to get to fly them someday soon once I figure out how best to video and time them.  ::)

Hey, Congratulations Jim! I guess you have been busy.

So you enlarged the venture to where it needs a bladder tank? And it worked?

Paul, yes the bladder works great. I used one on my Reed Speed Mustang. I used a Killer Bee backplate with a fine thread NV from one of the old Cox postage stamp backplates pressed into it. Or it might have neen one of the ones from Texastimers.com, same thing. It's harder to flood than a Tee Dee because if you slip and let the fuel flow too much, most of it just spills out the back of the engine. Fill the feed line, one good exhaust prime and it's first flip cranking every time, once you figure out where to leave the needle. If you don't have a KB backplate, you can bore one out. It's not critical as long as it's not too small.

Thank you Rusty and Jim!

Ditto what a Rusty said above. The only thing I would add is that it is critical you use the smallest fuel tubing available or you will flood the engine.
