May be a problem here, look at the bottom of the list..."Updated 09/06/08"

Henry Werner and his brother, the owners of Virginian Hobbysports retired about 2 year ago. Henry really knew his stuff and typically had about anything you needed.Ken

So........ Are we saying Virginia Hobbsports no longer exists?

I'd pay $42 for one. No prob.

Maybe I oughta call BHM.........

Unfortunately yes it sadly is gone. Larry Rice owner of Black Hawk doesn't sell direct. He may just reconsider that if you don't have a nearby dealer. Ken

Who's keeping the Virginia Hobbysport website up? Doesn't someone have to pay for that?

http://www.virginiahobbysport.com/ This pretty much confirms what I said. I met Henry at Brodak's a few times. He unfortunately sustained a very bad hand injury. This may have been a determining factor. Ken

Yes, I saw the retirement notice. Too bad they're gone. I actually bought a pennyplane from there a while back. Quite a while, I guess.

Henry tragically lost his son a few years ago and that probably was the last straw for him to get out of the hobby and safe business.
He still sells stuff on eBay from the hobby shop from his new home in Tucson. He goes by "vasafecracker" on eBay.
I just bought a kit from him a few months ago...

BJM enterprises had one for $46.80

So, I bought it. I am not really wishing to do the mail in lap times contest thing although it would be fun, just too many rules.

I have a TD 09 that needs some love and a little hot rod "Perky" is just the model for it.
I am guessing Dacron lines are out of the question?

Sorry about the VAHS thing...glad I didn't order one from there! :-)

George

Hey, no worries George. Nothing to apologize for.

I would not do dacron lines. The kit may suggest a line size. I have a model around that size but we just used .015 braided. Which is probably good as it had a massive amount of pull. Probably because it is so heavy.

Pm'd you twice.

Rolla

For contest purposes you need 52'6" steel lines of .014 diameter solid or .015 braided.

For fun flying...whatever you desire.

I noticed that the rules eliminate speeds over 90 MPH to keep it bfom becoming a cubic money contest.

Also - for contest purposes the minimum engine size is .14.

Well, I wanted to go 91mph so I guess that puts me out!

I do have an old Fox .15 that might be a winner. Kinda want to use the TD though.

Ken was saying the fuel tank location can be a pain.

I just wanted to do some straight line speed!

Here is Frank Carisle from Detroit flying his Perky. I haven't seen Frank in the past few years. I do recall when he built this. The 66 mph claims I can only assume as being authentic. I will say this the plane appears to be going faster in the vid than 66. Large stunters for example are flying in the mid 50's to 60 and this certainly is moving. https://www.youtube.com/watch?v=Ppvgri5EMXo Ken

Wooooo! That thing was smoking! Talk about motivation.

Thanks Ken, that was a great video.

Just for a comparison, in the video I posted under the Acme Rocket plane, I believe we timed the jet at 87 or 89 miles an hour. This is also on 70' lines though. We tried so many different fuels and other changes that day. You will see videos of R/c planes flying extremely fast. I have to tell you, 80 mph is pretty fast in control line. When you break into 100 it almost seems cartoon like as it is fast. I feel that Frank's Perky was going pretty well. Franks was using a Norvel .15. I don't recall if he was using a AME or a Big Mig. If the weight is good on the plane and the Tee Dee .09 would fly it, I wouldn't hesitate for a second to run it on a bladder. Ken

I do have a special .15 but, was planning on using that in a Jr. Satan. I do have some options. What do you think about the Fox .15?

Ron, I certainly imagine the beam spacing for the Fox is quite larger than a Tee Dee .09. You could certainly set your beam spacing for the Fox. I would make an aluminum plate 3/32" with the cutout for the .09 and fit it onto the beams. You could use the bolt holes from the Fox to hold down the plate while the .09 would bolt directly to the plate.This way you could try both. This plane should be purposefully built somewhat nose heavy. It becomes quite an engineering feat at times to try and make different engines work on different planes. Fox however recognized this early on making there engines interchangeable. Very few other manufacturers did this. The Fox .19, .25, .35 all share the same pattern. Ken

That's a good idea Ken. It would be a good way to work up to the speed. Would you happen to know if the standard .09 needle can handle a bladder? I haven't seen any fine thread KK needles for it.

Ron

Ron, I never tried it. I believe the threads are 80 tpi. However, I have many examples using remote needles. Bladder pressure usually needs a very simple fuel delivery system and a venturi isn't required. I would certainly give the stock needle a chance first. If that doesn't work there are many options to choose to make it work. Just like combat, I can say the majority of speed flyers are using bladder as well. I e-mailed Hank from Texas Timers in regards to a replacement needle assembly for the TD .09. He doesn't have one and isn't aware that one was made. My idea at first would be to eliminate the spring steel clicker and place fuel tubing over the needle and onto the nipple the needle screws into. This may seal any air leaks and also provide enough friction to keep the needle put. In reality, it should work. I just don't know how sensitive the setting is going to be. You can use a lower pressure bladder like Latex vs surgical tubing. I use Latex for 1/2A's even though my needles can handle thick walled bladders. Low pressure makes for easier settings and you don't get the pressure changes through the flight. When the bladder is full the run is rich due to pressure slowly leaning out as the bladder depletes. You may also put a restrictor in the fuel line. I've used beads from necklaces and copper tubing inserted inside the fuel tubing. Ken
