Default Brison 3.2 Wanted

The "Buy Sell" section of RCU is not working. Hopefully the Moderator will let me post this here. I need a Brison 3.2 with the mechanical advance and small propeller hub. The sensor should be on the side of the hub. A new one is preferred but a used excellent one is also a good candidate. The engine should look like the attached image. PM me with what you have. Thanks. Dan.

I still have one of the Brison blue case mechanical 3.2's in very good shape but I'd need a real good reason to let it go.

I once had a Brison that looked almost like your first picture but the timing ring was fixed with a set screw and there was no link back to the carb.

It had the CH synchrospark ignition.

Thank you soarrich but that is a much earlier version than what I am looking for. Dan.

OK Dan, curiosity has me asking this one. With all the "hot" 50 and now 60cc engines out why are you wanting this vintage engine with mechanical linkage et all?

I happen to own two of the 2.6 sized that run very well and had Gary polish the case and bead blast the head, freshen the rings, etc before he closed the doors.

TOM, tell me what it's worth and if I agree I will buy it from you if you want to sell it.

bigben,
1. I have several planes set up for the Brison. I need that backplate mount and side induction. Any other configuration would require a major rebuild.
2. I'm from the old school and I like the mechanical advance over the electronic because of its fast response.
3. I don't need the power of the newer engines. My planes are already over powered. I would rather have the reliabilty of the Brisons.
4. The standoffs introduce a very long cantilever from the firewall. I've seen those engines vibrating a significant amount as the piston bangs away perpendiculalar to the standoffs. You can't beat keeping the pistons close to the firwall for a secure and vibration free system.
5. I'm not a big fan of those rear input diaphragms. It's another moving part I have to worry about if the engine does not start or run poorly. I would rather have the carburetor get its input pulse directly.

That's enough. I'll have to change over one of these days. I can live with the OS 55 layout. Like everything else with OS it's expensive. A spare ignition module is $250. A carburetor is $150. Maybe one of these days. Not right now.

Dan.

There's a lot to be said for the bullet proof nature of an anvil. So many of the HP 50-60cc engines are somewhat fragile. They require rebuilds every couple of hundred hours. The typical Brison will run for much longer with minimal attention. The "weak point" on the Brison is the rod bearing 500-600 hr and the wear on the delrin ring 500-800hr. Both are simple to replace.

Mine are old enough they pre-date Brisson and are the A&M variety. Too bad they didn't hold on till big planes became as popular as they are now. Good luck buying a 3.2

The old Brison 3.2 is right in there power wise with anything of similar size produced today. It may be old but it is no wimp.

Yes Truckracer, the FPEs are a suitable replacement for the Brisons. I have considered them. I don't know why the 3.2s are not being made any more. Maybe Mahle(Makita?) stopped making the pistons and cylinders. That would be a major redesign for FPE to get everything rebalanced. I'll keep them in mind. For now, a good used or even new Brison would be the easiest for me to deal with. Good inputs, all you guys. Dan.

I would guess FPE changed to the Husk. cylinders because they were cheaper .... just a guess though. I fly a FPE 4.2 on occasion.

FYI, I recently went through the same search you are going through .... only I was looking for a Brison 2.4. Found one that was actually new and had just sat around for years unused. Excellent price too. Keep looking, they're out there to be found.

Default RE: Brison 3.2 Wanted

Hello,

I am glad to see this post as I am old school myself to a degree and happen to have a Brison 3.2 and a 6.4. The 6.4 has some time but well taken care of and inspected with a clean bill of health. The 3.2 was purchased just a bit before the doors closed. In my years of r/c this was "THE" engine and would probably be in the running if Gary was still open. It has the Synchro Spark and the engine has at most all of an hour and probably closer to 30 minutes. At this time I have no plane for it but not at all interested in selling but just curious what it would honestly bring. The case is also polished. It could easily be changed to mechanical advance but a different ignition box would be needed and could probably be exchanged/traded here on RCU.

Thank you,
John

I saw they had DLE's on the table at Toledo this past April as did everyone else.

Fox needs to change their web site if they don't sell the Fox engines anymore?

You can buy DLE's most anywhere.

I see that as a poor move for for Fox.

The only way to stay competitive with the same product as everyone else is with price or service and they don't have the edge on either one with that line.

Whoever made that decision never had Marketing 101 in school?

John, there is no reason to keep the engine lying around unused. Sell it to me and you will be much happier. Me too. Dan.

The Mahle top ends are still in production and easily obtained. Not cheaply, but easily. The problem is likely with the cranks. If the previous supply ran out then new would have to be made and it takes awhile for the Chinese to make a halfway decent crank.

Dan,

Thanks for the offer of purchase but I don't want to sell one of the best engines I have ever made. It would not go low on the sales amount even if I did, which would scare away most people.

I don't belive the FPE cranks come from China. They have always looked like some kind of home brew affair ..... machined mainshaft and counterweight with pressed in crankpin. Certainly not a forging like most of the cantilever cranks we see these days. I sure could be wrong though.

Any Brison component that is not part of the old Allison inventory is now made in China and later assembled in Canada. At least that was the plan told to me by Kangke people after they took over Brison. Not at all certain but I would guess the China business model would insist any new parts be made "at home" to better satisfy profitability.

TOM, I was referring to Dan's and my discussion (posts 17 and 18) regarding the FPE change from Sachs to other cylinders .... I believe Huskvarna (sp?) Sorry for the confusion.

I have no clue what is in a current Brison engine for a crank.
