Classic Questions Answered: Landing gear speed brakes
The following was asked regarding the WC Calypso Replica landing gear speed brakes:
Rusty,
Thank you so much for the pictures, very helpful. The Conquest IVe (Electric) with a 13x10 apc freewheeling up front just does not slow down and landings are difficult. I am trying solve that problem.
I have a couple of details questions:
1.) Did you wrap the strap all the way around the strut so that the bolt goes thru two metal holes or did you cut the strap and the bolt only goes thru one metal hole?
Answer: The strap was soldered to landing gear leg then the extra ear was removed and ground smooth.
2.) It looks like you only soldered the top stap, is that correct?
Answer: Both the bottom and top tab were soldered.
3.) Did you use a light weight plastic for the brake itself?
Answer: The 1/16 ABS plastic was a scrap from an ARF. 1/16" plywood would be fine.
4.) Is Four Pi still in business? I called to order the straps and got a generic machine.
Answer: I see the nice couple who own and operate Four Pi at midwestern swap meets. I also found this link: http://www.fourpi.com/
The big question is your model should be able to land slow and predictable like the typical classic pattern model. I have had a Conquest VI and the first flying Conquest 120 and found them to be very docile. I also have an original Phillips Aircraft Conquest IV and will make it E powered.
Good Luck!

Rusty,
Thank again. In this case the pictures did not tell the whole story. Thanks for filling in the blanks.
The Conquest is predictable but it just does not slow down like a Classic. I literally cut the throttle on the down wind leg, make a deep, wide final turn and it is still hauling butt when it get over the end of the runway. I cant seem to get the classic "nose high" attitude that allows you to feather the throttle to land it right in front of you for the judges. I have attributed this to two factors; 1.) the plane is very clean aerodynamically (No Cylinder sticking out, not pipe, no switches, no nothing) and 2.) the highly pitched APC 13x10 does not provide much in the way of prop braking. The Scorpion 4025-10 would like a bigger prop than 13" but it will not fit on this design, the pitch has to go up. I have recently installed a new ESC with a brake feature to see if this helps as well.
I will add the brakes as well and see how it goes.

Larry,
I had replied to your post but my answer evaporated - RCU bugs.
I was suggesting you start a new thread so we could take up your big Kaos project. The wing should be pretty straight forward to loft and get a nice LE and TE pattern.

Classic Props
The picture shows a collection of nifty props from the 70's. I spent a few days testing the best props and the short answer...they are all "paint stirrers"! The APC props produce so much more horsepower that it is funny. The old props make lots of noise but less power.

Rusty,
try out the newish Falcons. See what you think. They weigh about half as much as an APC so they spool up and down faster. They also rev higher for the same reason but probably still don't generate as much pull. Basically they would favour top end power while sacrificing torque. Not necessarily desirable but interesting to compare nonetheless.

Nice collection, Rusty! Where are the Asanos? While engine technology changed somewhat during the '80s, prop technology took a quantum leap forward. Getting larger diameter and/or higher pitched props back in the early days of 'turnaround ' was challenging. D&W made very nice, reasonably priced props, but their production rate could be a little slow. Asanos worked pretty well, but were pricey and sometimes hard to get. My first Joker was powered by an OS .61RF with a Perry pump (the RF-P version wasn't available yet). After considerable experimentation I found the MK 12.5 x 8.5 +1 (progressive pitch to 9.5 at the tip) worked very well. A year or so later, Mack Patterson (of Mack's Models) sent me some prototype APC props. There were several different variations (shape, blade width, etc.) and the good ones were terrific. I will have to excavate my collection of early APCs and post a photo here. I've run nothing but APCs ever since ... and have the scars to prove it!

I thought I'd post a few pictures from my collection too. Although I haven't ran a 61 RF-P yet I have run a 61 SF-P on a Super Hots I had. The SF-P did have more power than the 61 FX that was on there before. It's a little hard to tell in the picture but the Rossi 91 is noticeably larger than the 60. It's 880 gr, rated at 3.9 hp at 15k rpm with a 14x5, 14x6 prop and features an inflight mixture control.

Classic Curare: Official Hanno licensed via Schweighofer
The long term relationship between Hanno and the Schweighofer's was rewarded with the release of his famous Curare in the last few years. The ARF is offered in electric and glow and is a very high quality.

Does anyone know the cost to ship to USA...crazy for me not to have one.

Classic Bootlegger
Steve Helms created the Bootlegger and incorporated an enclosed pipe and anhedral stabilizer. I funded my R/C modeling activities building, covering and painting models for others. This provided a 13 year old with enough cash to buy fuel, props and parts. One of my projects was the Bootlegger. I remember aligning the stab and grinding the polyester resin fuselage!
The photos show a kit and a completed model.

Classic Chip...my oldest son is 12 today!!!
I am proud to share that my oldest son Chip turns 12 today!!!! In 2007 he made his first flight with the same model I soloed the Carl Goldberg Falcon 56. I was inspired by Rhett Miller to learn to fly on the Falcon 56 reading the Carl Goldberg ads in American Aircraft Modeler. Model aviation has provided so many experiences, opportunities and collection of my favorite individuals I have ever met.
I encourage everyone to share your knowledge of modeling!

Congrats to both you and your son! What we need is more young faces involved. We are just getting older, and if we do not have young blood to carry on this hobby, it dies with us.

Classic Ivan Kristensen: Summit
Ivan Kristensen was one of the giants of the 70's,80's and 90's and still is active as evidenced by his participation at the IMAC World Championships recently held in Muncie, Indiana this past August.
The Summit series of models followed his celebrated Saturn kited by Fliteglass. The Summit II won 1985 US Nats and finished 5th at the 1985 World Champs as piloted by Ivan. Yes, I have a Summit II kit which is very rare and pictured below.

Yes,
Ivan's last name is of Norwegian/Danish origin and means "Son of Christen". Much like the forms Mac and Mc used in Scotland and Ireland, the Scandinivians named their sons after their fathers something that dates back to the Vikings.
He currently lives in Hamilton, Ontario (and has for quite some time if not the entire time he has been in Canada) and has quite an active blog site with all his activities related to the hobby and sport including the rebuilding of a full scale airfcraft.
