EDITED

I've been asked again if I would do a run of Fox 36 Mk 4-5.

Again, I'm happy to do these if there are enough numbers. WE HAVE ENOUGH NUMBERS

They will be stock Mk V timing and include piston/liner/rod/pin/head shims/backplate gasket.

Also doing Tyndal double bubble head buttons to suit stock long reach plugs, and also Nelson head buttons. So let me know if you want either or both.

Piston/liner/rod/pin/shim sets will be approximately $115 to $125 Australian dollars. Don't know what the head buttons will be $.

So anyone wanting extra parts such as head buttons, rods, additional backplate gaskets needs to let me know so I cater sufficiently.

Brian, I will take one set and would strongly recommend standard spec. C. T. Schaefer

Brian

I'll take 4,

If the Wiley spec makes more power SUPER

If not standard is fine

Mike

PS If Brian does cylinder heads I would take 6 to 8 of them

I agree, keep it stock but do all the series from the MK 3 fit to the MK6? Al, without me taking mine apart is the crank the only difference in the MK6? I know the diameter is bigger but the crankpin is still the same with the same stroke?

John Given · « **Reply #6 on:** March 07, 2020, 08:35:22 AM »

Hi Brian.

What is the minimum number to make this happen.

OK to share this on the MACA FB page?

Paul Smith · « **Reply #7 on:** March 07, 2020, 08:53:51 AM »

I assume that you are writing about replacement piston & cylinder sets for the Fox Mark 4, 5, and 6?

Please state your price.

Fredvon4 · « **Reply #8 on:** March 07, 2020, 10:27:35 AM »

4 and 6....5 is a failed anomaly

I tried twice to get Brian to do Fox 36 MK IV..MK VI internals....never got enough pre orders and argument with Jeff Dawson and I about stock timing vs Willy ...Jeff wanted more aggressive Willy dimensions....I wanted stock better parts

I still have several NIB Fox 36 MKVI.....sold a butt load of my Marvin Denny FOX 36 IV/VI s to a guy in Oz
I am out--- not ordering.....but if Brian needs a factory Fox 36 MK IV...(with "C" on port side) I can send the sample for measuring

editd in.....BTW..Brian occasionally includes heads and gasket/shims....someone should send a Tyndall Hemi head to replicate...C.T Shafer can elaborate I bet....

and if someone wants or needs a stock new MK VI...make an offer

John Given · « **Reply #9 on:** March 07, 2020, 01:04:36 PM »

The Mk. VI P&L will also fit in a Mk. VII, correct?

OK to share this thread on the MACA FB page?

Brian Gardner · « **Reply #10 on:** March 07, 2020, 04:51:30 PM »

I need 20 units ordered minimum.

Price would be approx. $115 to $125 Australian dollars (plus shipping). That is for piston/liner/rod/pin/shims.

If you want some different head inserts that will be extra (not sure how much yet).

I don't have experience specific to this engine, so it is up to you guys to come to a consensus as to what you want and supply preferable 2 sample engines.

OK to share to other places, but I don't want to be chasing around various noticeboards etc to collate numbers. So I'd prefer all requests on here.

Brian

Fredvon4 · « **Reply #11 on:** March 07, 2020, 06:37:28 PM »

ok to share...I tend to think....never owned one..that Fox 36 Mk VII (Mark Seven AAC) had more changes and not real compatible internals like MK IV ---MK VI

Brian is NOT offering to do MKVII internals... firstly too few example out in the real world vs MK IVs and MKVIs

if the 20 pre orders lack one or two I will ask for one set....

NO, the Mk VII Liner WILL NOT fit in the Mk III - Mk VI case, it has a much larger OD.
Guys in are club would put Mk VI ABC piston & liners in their MkIII & IV engines that had the steel internals, and ran them in our Warbird racing event.
I think using the porting in the MkVII would make a stronger running engine, but the case might have to be modified to take full of advantage of the ports.
From what I heard, Fox supplied a .020 liner shim for the Mk IV, to raise the timing for more power.
New head buttons with a double bubble chamber, using a Nelson or turbo plug would be cool to have, I would order at least 4.
I personally never measured difference in the rod or crank pin between the MkIII to MKVI engines, but the the bore is the same from MkIII to MkVII. The Mk VII has a much larger crank pin.

The MkIV Crank will fit in the MKIII. The Mk VI and MkVII cranks only fit their specific engine.

kenneth cook · « **Reply #13 on:** March 08, 2020, 06:32:58 AM »

This is exactly what happened the first go around. I has asked Brian about producing these due to two catastrophic losses I encountered. What I'm aware of is the MK 3 and Mk 4 use identical cases with a crankshaft difference but will interchange between both. I also believe the 4 had a needle valve option high or low.

The 5 is a combination plain bearing and rear ball race with a completely different shaft but I noted the MK 3 cylinder and piston fits with just some very slight porting differences but it still works.

The VI which I own two is a completely different animal which was ABC and I could be wrong here but I believe I have a 4 with VI internal piston sleeve making my 4 a abc. So if I was to purchase what I believe is correct in my thinking, would I be covered from my MK 3's- to the 6? It certainly sounds that way.

Lane Puckett · « **Reply #14 on:** March 08, 2020, 11:49:45 AM »

Brian,
I can supply you with a couple of new P/L'ers(2) and a new motor(1) for your project. I'll want them back. Also have stock and custom rods(RPM and Aussie rods) for the Mk VI if you are interested in duplicating one of those.

You REALLY need to have Don Repp weigh in on this discussion. He can tell you exactly which direction to go.

My opinion is go with stock replacement and if folks want a different more aggressive timing then shim it and get a new head insert made.

I have way too many motors and spares now but if I can, I want to help you help others.

Thank you,

Lane Puckett

Brian Gardner · « **Reply #16 on:** March 11, 2020, 04:20:43 PM »

OK guys, between here and direct emails I have enough people to go ahead and do a small run of these.

It would appear the consensus is stock timing.

I need a good sample engine as a loan to go ahead with this. Also any head buttons or aftermarket rods you guys want replicated.

Brian

Anyone else???

Brian Gardner · « **Reply #19 on:** March 12, 2020, 07:50:58 AM »

A set will include piston, liner, rod, pin, shims.

I can do head buttons and extra rods if wanted provided they are pre-requested.

Dick Tyndall · « **Reply #20 on:** March 12, 2020, 06:55:29 PM »

Brian, I can probably come up with one of my "double bubble" head inserts that I sold many of back in the '70's and '80's. These will fit the Fox MK III and the IV. I will dig up the drawing for these, also. These inserts were made for standard long glow plugs. I didn't make any of these for the Nelson plugs. I'll get something in the mail to you soon.

Brian,

Will you build the heads for Nelson plugs or will they use standard?

Mike

Dick Tyndall · « **Reply #25 on:** March 13, 2020, 08:12:54 AM »

Personally, I don't see the need to make any head inserts for the Nelson plugs. Back in the day when I was making these inserts and flying Fast Combat I was using Rossi R-5 long glow plugs with 30% nitro fuel with Fox MK III's on 19 ounce foam wing airplanes and running 122 MPH. The plugs held up fine . The Rossi plugs are available from Alan Hobbs who lives in Montana. I believe the R-5's are $4.00 each. I don't think you would see much, if any performance gain by using the Nelson plug. Just my opinion.

Brian Gardner · « **Reply #27 on:** March 13, 2020, 10:49:24 AM »

People have asked for both the Tyndal double bubble head button and also Nelson. So I will do both.

So those that want head buttons need to let me know which type and how many to add to the list.
