Brett,
Congratulations on the new project!! Looks like you did well.

Welcome to the team.... great bunch of folks here!

Cheers,

The model 4 is a great aircraft.
You'll love it's flight characteristics no matter if you go "full" Speedster (short wings) or full length wings. I've flown both many times. With either the 80 hp 912 ul or the 100 hp uls you will have great performance with a very respectable load carrying capacity.

Ordering the new wing fuel tanks and an aluminum header tank is a good idea and will make it more reliable. The Grove gear is a plus also.


Enjoy the forums and thank you for your service in the Navy.

welcome aboard chief . not sure i under the classic speedster thing . either its a classic or a speedster . if its a speedster the wings are already shorter . my IV 1050 has long wings and my friends speedsters wings are one bay shorter each side . a speedster should perform pretty well with a uls engine , they go really good with the ul as it is .
good idea , installing the new production tanks . couldn't tell from the pics if the wings were built for the big tanks or small tanks . i had two small tanks in my wings which just isn't enough gas . replaced both with the new 13 gal tanks .
there are a bunch of guys that are building or flying model IIIs and IVs that hang out here that are willing to help when a question comes up .
brown shoe , hadn't heard that in a while . did my navy time . got out a AE2 AC.
never had to go on a boat, thank goodness . did acquire 1700+ hours in the nose of a p2v.

Thanks for the warm welcome all. It's appreciated.

np Desertfox4. It was my pleasure.

Hey cap01, thanks for the welcome aboard! You were an AE - good on you mate. Lol - yea the shoe color is a term of endearment my surface navy mates and us aviator types give each other. Purely out of respect you see... I'll spare you all of the many innuendos involved here. All in good fun.

My wings as of now, are full length. I have all the speedster stuff in the kit. Maybe it was ordered as a classic with speedster mods? It's beyond my noob understanding at atm.
The fine fellow I purchased the kit from ( also retired navy) showed me the wings, and they are untouched and are still full span (32 ft)
The wings can have the two larger, 13gal fuel tanks.

Here are few more pic's of when he received the kit... Did everyone receive their kit with pre-built wings? Or was this a quickbuild option?

I purchased my Classic 4 kit in 1994. The prebuilt...Quick build...wings were an option. $1095 labor only.

The speedster wings are built full length and cut outboard of the number 9 rib after the ribs are installed. It is necessary to do it that way to get the proper twist in the wing.

Welcome aboard, I too am retired Navy. 21 years, Master Chief Machinist Mate (Submarines).

I may be interested in the A-65 when the dust settles. I also have a '41 Taylorcraft with the A-65 and I have been thinking about overhauling a different one to have it ready for when this one wears out.

When you are ready to unload it, let me know.

In addition to what everyone else has said. You may be able to modify yours to be speedster length by just cutting off the last bay and relocating the end rib bracing(keeps structural integrity for fabric shrinking.)... Or you could make removable wing extensions. Double check this, but I believe the spar insert location and length is the same for both wing types. The only difference is a minor adjustment in where the strut attachment is located for a lower dihedral. I have the speedster length and I find they are only for looks. I am a firm believer that the decrease in wing area decreases my lift to where the increased angle of attack needed to hold level flight creates more drag than longer wings of higher lift would. You will take of shorter and fly faster with the longer wing in my opinion.

Attached a pic of my speedster wing. Lots of build pics in my albums.

A note on dihedral. When I started building in 1993, I debated cutting the wings and during the wing rigging, I contacted the factory and asked about the importance on the dihedral as on the Speedster (flatter) vs. on the standard Model IV. I was told there was no difference functionally. I mention this because my long time best kitfox buddy always complained that his Model IV looked like a landing pigeon. My current Model IV's dihedral was set by the guy that started the kit and I wish it was flatter for looks. A year or two old article in Sport Pilot bore this out as it mentioned that dihedral is important aerodynamically in low wing designs, but not so much in high wing designs. The reason I mention this, is you can either use the flatter Speedster dihedral as in that section of the manual or the more pigeon like as on the regular Model IV.

Welcome to the group. I think you have found a treasure. I put all the speedster mods on my 1993 Model IV except the clipped wings and wheel pants.

Brett,

Congratulations on the Fox!

Just as a point of reference, in case you haven't seen it, Service letter 27A speeds reduced further from Service Letter 27:

http://www.kitfoxaircraft.com/suppor...ters/sl27a.htm

The 1200 Vno is 95, the Speedster is 108 and states: "Maximum structural cruising speed is the speed that should not be exceeded except in smooth air, and then only with caution. It is indicated at the junction of the green and yellow arcs."

you will see cruise speeds in the 120 mph range

"caution" obviously subject to interpretation!

Ty on the clarification tj

Thanks for the info Geowitz. I'm really torn at cutting a perfectly good wing. I'll have to really think on it. Most of my flying is just for fun and the STOL is more important than the speed. However I like the looks and roll rate of the shorter wing. With the 912uls it would be a load of fun! My daughter lives out in San Diego so I can see some flights to visit her. Speed would be good...

Hey vetdrem, ty for the welcome aboard.

I'll have to go over the A65 more closely to see what shape it's in. To be honest I don't know anything about this type of engine. If it was a ford fe v8 that would be different.
I do know the mags, oil tank, carb and intake are NOT included. When it ran last is anybodies guess. Maybe the owner will produce some engine logs, maybe not. We mostly talked about the kitfox. I did see the engine on an engine stand and it looked good but I have no interest in finding the missing parts and "building" it to sell as a running engine. As of now, it will be sold as is for core value.
You tell me if it would be worth it to track down the parts and get it running? I just don't know.

Shoot me a pm if your still interested. Maybe with your knowledge of the motor we can figure out if it's worth your time and effort.
I can do some precise measurements when it's in my possession to find out if the core is worth anything...or if it's a boat anchor.
