    RE: ASP/MAGNUM FS400AR Rebuild/Overhaul

    Those are impressive numbers Rev! There's no doubt APC props make thrust. That is why they seem to be the most popular prop in use worldwide.

    Dan, I like that little check valve! But in further thinking I realize it would not be appropriate for use on the FS400 with the RIM manifold as the crankcase needs to be closed during operation.

    It will be closed. It is out only. As long as there is neutral or negative pressure such as when running it will be closed. One woild have to apply positive pressure to the case somehow to expell the oil.

    Maybe some sort of rubber bushing W/a tube inserted into the carburetor to (gently) pressurize the case to blow the oil out.

    It would beat removing a plug every time & waiting for the oil to drip out.

    Now that I think of it, would closing the throttle & counterrotating the crank pressurize the crankcase since you intake manifold uses the crankcase as a plenum?

    Any slight pressure increase in the case would crack the checkvalve & expel any accumulated oil.

    RE: ASP/MAGNUM FS400AR Rebuild/Overhaul

    Thanks shes a bit of a beasty to fly, ALOT of rudder input is required all the time and shes also very twitchy in pitch. The main issue is the crappy robart retracts keep giving trouble

    Hey Rev, you are right about the retracts. I have broken them 5 times in the 11 flights the model has had. I am looking for upgrades as the robart jobs are hopeless.

    As for the 7-77 i look forward to that! where do you find all these bargains?!!

    sadly not. most american products comming into the uk go through another company before getting to the uk distributor. As a result the price is a good 30% higher than it should be. Thats why Great Planes kits cost a fortune over here

    RE: ASP/MAGNUM FS400AR Rebuild/Overhaul

    I priced the cost of the Rogeau Intake Manifold and was quoted 300 euros plus 25 euros shipping and 4% additional for using PayPal. This comes out to 338 euros which converts to $443.00. That is 57% of the engine price for a replacement intake manifold. As much as I would like to have this manifold, I will have to pass. It is just too expensive for me and I will run my engine with the stock intake manifold.

    It is also the price that kept me away. Thats a lot of Euros even in the EU. If we werre talking about a Moki 250... ok, but like you said, in the end its "only" a 700 EUR engine. And as long as my engine is running this well Never touch a running system.

    RE: ASP/MAGNUM FS400AR Rebuild/Overhaul

    After getting rid of the 450 I spent some quality time with the 400. It is really roaring in the stearman and I think it may just have enogh power to fly my light version of the SiSt Focke Wulf.

    Some of you may have noticed I like buying scrap stuff an repairing it. This FW-190 is no exception. Came in too slow and cartwheeled on the previous owner. Misfortune for him, good luck for me. Rev got himself a rather cheap full composite SiSt FW-190 with sierra retracts and all.

    Lots of small damages in the gel coat to fix, one wing really got it basically a lot of work.

    This was two years ago...

    RE: ASP/MAGNUM FS400AR Rebuild/Overhaul

    In the meantime most of it is fixed and I you may ask what I mean with "Light Version".

    Most of the SiSt 190s fly somewhere around 33lb with a G45 or a G62. They usually carry around 2kg of lead in the cowl.

    My goal is to get this baby under 26lb. Might just be possible I want to shed as much weight in the back as I can (Elevator Servos to the front, make those Elevators and that Rudder really light, ...) because every gram I shed in the back are 5 lost in the front.

    Hi REV,

    I purchased my 400 radial from Hobby King for $777.00 US Dollars, that converts to 595 Euros which makes the financial differential for the Rogeau intake manifold even worse than in EU.

    $443 buys a lot of paper toweling to wipe my Fleet off.

    I'll put up with the oil.

    agreed, you can also buy a collector ring and that will keep the oil from spraying everywhere. Also as i am running with the drain plug in i may buy some lower oil fuel for a test. i honestly think 10% would be ok even with the standard engine

    Carosel43, I was thinking of the collector ring to route the oil around to the bottom of my Fleet's fuselage. I have to take a closer look at my engine/cowling setup to see if the clearance is there.

    Tom, I know you fabricated a collector ring from scratch. Is it possible to outline the steps that you took to build it or is it documented somewhere else?

    RE: ASP/MAGNUM FS400AR Rebuild/Overhaul

    Hey guys,

    I agree with you all that the price of the Rogeau manifold is high. When I bought my engine in 1996 I paid $1100 for it and that was a deal, because most sellers were at $1400. So that would have made the RIM 1/3 the cost of the engine as an upgrade. Today, HK sells the same engine for $777, so as Dan pointed out the 57% seems extreme as an upgrade part.

    I suspected, and Mr. Rogeau just confirmed, that he makes no profit, zero, on this part. The cost he asks, is what he paid the machine shop to make them.

    From the horses mouth:

    Hello Tom,

    I know the RIM price is high, and more for USA because of the money conversion, but I sell the RIM exactly at the cost I pay the French manufacturer, it was a technical challenge, not to become millionary Β°)) . I ordered "only" 5 RIM each for OS and ASP, they are quite sold, and I will order "on demand" now ; When Chinese will copy this part, they will sell at a lower price.


    So there you have it. As he says, the Chinese (Sanye) may very well copy this and incorporate it into their manufacture of the engine. Or maybe Hobby King might just make it! Of course Mr. Rogeau will not see a single Euro from it.

    As for the benefits of this manifold, even at the current price, there is more than just the reduced oil on the outside of the model airplane. According to Mr. Rogeau, and I have no reason to doubt this, the RIM also increases lubrication to the critical internal parts of the engine. This is quite obvious, actually. And in turn, this results in longer life of the parts (my opinion). He also states that by virtue of all the parts being coated by oil, they are more protected from corrosion and rust formation. This also seems pretty logical to me.

    It was a labor of love, for Mr. Rogeau. And he wanted to make it available to others. It's too bad he did not connect with a Chinese mfg'r himself, to have it produced in quantity and at a cheap price. I am sure the French race car prototype shop that he used to machine these manifolds makes lots of awesome stuff, but they definitely do not give it away cheap.

    I have become quite good friends with Mr. Rogeau as a result of this project. I am very fortunate that he chose me to test his manifold on my engine, so that I could write about it "in good English" on the American forums as he put it. He is uncomfortable with his level of English skills. In the process I have learned a lot about him, what he has done and continues to do for modelers. The magazine articles he has written, how-to video's he has made for Youtube, manning booths at model airplane shows to help other modelers with their engines, etc. He truly is "one of the good guys" in the hobby.

    ~Tom~
