Tee Dee .09's Empty Tee Dee .09's

Post  AT1984 on Tue Aug 16, 2011 6:08 pm

Does anyone on here have Tee Dee .09's? I now have two...haven't run them, yet. I have a conversion head that will get used on one of them (maybe). Next, I need to decide what plane to build. I've had a few suggestions. One was an "Easy #4", and the other is a Ringmaster Jr. I'm leaning towards the Ringmaster, though the Easy is a really cool looking plane...we'll see.

It's cool to have a forum dedicated to Cox engines.

I have one, I have never ran it. I did run my friends medallion .09, they are fun engines! I just looked it up and the ringmaster would look good with a TD .09 in it.

The kit I'm looking at is the PDK LLC Laser cut kit. Really nice looking.

Yes that sounds good and the laser cutting makes kits a lot lighter. I would want to build a baby ringmaster for the cox tee dee .010 that looks like fun.

The Ringmaster Jr. should be a good match, as would the Brodak Jr. Flite Streak and the SIG Akromaster. I think you may find that the TD .09 is more like a .15 power wise.

You mentioned a conversion head...if that's for diesel, watch out for overheating. DDD once wrote that he decided to not produce a head for this engine because of the heat.

Good luck with your TD .09's.

I thought he meant a conversio so he could use a regular glowplug?
I thought he meant a glow plug conversion so he doesnt need to buy expensive glowheads

Good luck with your TD .09's.

George,

The conversion is a glow head conversion.

GermanBeez,

I haven't heard a Cox engine run since I was WAY younger, but I would imagine that they are loud!

I see you are from Bavaria. I was stationed in Schweinfurt (82-83) and Bamberg (85-88), when I was in the Army. I was stationed in Wiesbaden in 01-04. I liked Bavaria much more than Hessen!

Glow head conversion that's what I thought they seem good for the .09 but the .049 one leaves the engine down on compression and therefore power because standard glowplugs seal in the wrong place.

Tee Dee .09's Empty TD .09

Post  dankar04 on Thu Aug 18, 2011 8:43 pm

The Ringmaster Jr. fly very well with the TD .09. My friend allways brought his and we all flew it. Amazing it lived. Engine was very user friendly. I have Sterling P-38 and will power it with two TD .09's.

A little explanation for those who are not aware...

The "normal" 1/4"x32 glow plug seals at the gasket, thus leaving any volume around the threads as part of the cylinder volume.

Nelson and Turbo plugs seal at the bottom of the plug, thus excluding the thread area from being part of the cylinder volume. I HAVE READ that this gains you 1K-2K RPM of performance over the 1/4"x32 plugs. I have never checked it out.

As the engine gets larger, the precentage of volume taken up by threads gets smaller so at .09 it should not make a lot of difference.

George,

Thanks for the explanation. I'm starting to learn quite a bit about these engines.

As for noise, the .09s are VERY loud. Personally, I love the raspy sound of an .09 in flight. Your neighbors probably won't.

I've got a Med .15 but have never run it. Needs a glow head. I bet it is ear-shattering when it revs up proper. Smile

I still haven't tested these...It keeps getting put off. I don't think the neighbors will care too much. One of them tests his outboard boat motor quite frequently. It sure isn't "quiet"!

My neighbours argue at all ours of the night and have long late and noisy parties. So running my engines Is my form of pay back.

I have a original first version TD .15 and it is LOUD. The carb body is cracked so it is doesn't want to run steady, I am getting a new body for it one of these days. I could also use a new drive plate as it looks like someone used a pliers on it. When I was buying it, the hobby shop guy said he pulled it off a wreaked plane so he thinks it was in a crash. The downtown hobby shop (hobby warehouse) I was at also sells the "trade in" engines so you never know what they may have.

Tee Dee .09's Empty TD .15 carb body

Post  AT1984 on Thu Aug 25, 2011 7:59 pm

This seller on eBay doesn't have any active listings, right now. The link is completed listings. He makes CNC machined carb bodies for Tee Dee's. You might want to contact him, to see if he has any in the works. He does have them for the .09's, but they weren't listed.

Hub Hobby Shop is the rudest hobby shop and the only reason I go there is because they are right up the road from my house. Hobby Warehouse is about 20 minutes away, I have only been there about 5-6 times since it is not the best part of town after dark. They usually never have cox things but I like to look at their used engines.

I talked to him about the .15 body about a year or 2 ago, he just said that it is still on the drawing board.
