    Supermarine on Floats- Need help!!!

    I just purchased a Supermarine on Floats locally. The seller who sold it to me does not know much about it. The Supermarine appears to look very much like a Spitfire.

    It is the S6-B Supermarine, Blue and Silver color.

    The dimensions are: Wings Span 90" (3 piece wing, with the two ends coming apart for trasportation)

    Length 80".

    Floats length are 70"

    The plane came with Servos and no motor. I am not sure if it ever flew.

    Questions:

    1. Who makes this plane or kit?

    2. What motor is required for this plane?

    3. Are the 70" floats too big for 80 inch fuse?

    4. I have flown mainly cubs on floats. How difficult whould it be to fly the supermarine?

    5. Any other comments or suggestions would help.

    RE: Supermarine on Floats- Need help!!!

    I believe the S6-B was just before the Spitfire, early 30's vintage...It was a Schnieder cup trophy racer, and a very hot machine for it's time! The full scale A/C had huge floats in comparison to the fuselage, so it might be a scale plane?

    I don't recall seeing a kit of it, not in that size anyway, but somebody else might know...I'd say it's probably scratch built from plans.

    The weight will help a lot in determining an appropriate engine...How much does it weigh?

    It's a "racer" so it ain't gonna be much like a Cub! so I would suggest some help, at first anyway...

    Personally, I'd say if it's not too heavy, and it's built strong and straight, it oughta fly quite well, (maybe)

    Give us a little more info...

    RE: Supermarine on Floats- Need help!!!

    RE supermarine S6B
    I am building one from plans. My floats (still on the plans) will be as long
    as the fuse minus the rudder. What little I have found says it was some plane. They apparently only
    made one. so no varity in paint schemes. Blue & silver don't impress me for visibility.The blurb w/ my plans say it cut at least one timed pass @409 mph in 1931 I bet it still holds the speed record for prop drive float planes.

    RE: Supermarine on Floats- Need help!!!

    The Supermarine S6B was the third seaplane racer to come out of the Supermarine factory in the late twenties and early thirties. There was the S6, S6A, and finally, the S6B. With this plane, the factory outright won (winning 3 years in a row) the Schneider Cup, beating the Italians. These races were the first time that G-LOC was experienced by pilots in the turns and several were killed before determining the cause (One fellow managed to regain consciousness before he crashed and thus they figured out what was happening). The lessons learned from the development of these racers were instrumental in the development of both the later Supermarine Spitfire and the Rolls Royce Merlin engine, without which Britain certainly would have had a much harder time during the Battle of Britain. By the way, the designer of the S6 series racers and the Spitfire was Reginald Mitchell. Soon after designing the Spitfire, Mitchell died of stomach cancer. Although he did get to see the aircraft prototype fly, he passed away before production started and never knew the contribution that his design made in helping to win the war.

    Cheers!

    RE: Supermarine on Floats- Need help!!!

    Back to the original question... It sounds like one of the giant scale Schneider racers that were scratch built for the Schneider reinactment races held at Lake Havasu for several years in the early 90's. I may know the specific airplane, but I'd have to see a picture to be sure. The one I'm thinking of used a custom built OS 600 four cylinder four-stroke. Weight as I remember was over 30 pounds. It was heavy, fast, and not easy to fly. Most of the others used 75 to 100cc gas singles.

    sounds like the Pepino sb-6,the plane flys well with a G-62,floats are big but scale,they held fuel on the full scale

    RE: Supermarine on Floats- Need help!!!

    Hi Grandslam,

    If your S6B is built up from wood, it was most likely done from Jim Pepino's plans which are still available. I think Mrs Pepino runs an advertisement in Model Aviaton magazine amongst others. If it is a fiberglass fuselage then, it is most likely from the molds that Kenny Bundt ( Think Byron Originals) built for the Schnieder Cup races at Lake Havasau in AZ.

    The reason I know is that I bought the tooling (Molds) from Kenny a few years ago and laid up fuselage for myself and a friend. It was allot easier than cutting out all those formers and bulkheads and sheeting everything up.

    The molds are currently at ConachenAircaft.com and Jim also has a set of fiberglass floats available to go with the fuselage for those who may be interested.

    I have yet to build mine but I can tell you that you need to check the floats to see if they are built to scale with the curved waterplaning surface or the flat waterplaning surface. The curved surface (scale) is tricky to take off from water. Jim and Myself determined that to make life easier, a flat waterplaning surface (as most current float designs are now)would make takeoffs alot easier. Besides, at a 100+ MPH, who's going to notice what kinda float bottom shape you're running!

    Post some pictures of the bird as soon as you can and good luck with your S6B.

    I was away for a while and therefore, did not have the opportunity to log on RC Universe.

    Thanks for all of you who responded and provided helpful information.

    Yes, the plane is all wood. I was told it was in a Meseum for a while. The plane appears old.

    I will get tome pictures and post them. Perhaps that will help someone recongnize it.

    Thanks again.

    Hi I will try posting some pics and links..theres tons out there but this will help you a bit I can only add a bit at at a time but here goes tell me when youve had enough but thats a very big Plane....if its true to scale be warned the originals had some control issues the control surfaces on the tail were a bit on the small side. the floats sound about right ...big boots and skinny panties on these birds[X(]

    RE: Supermarine on Floats- Need help!!!

    I've seen a couple of these flown with G-62's and talked to the builders. With the scale float design, they are very, very tricky to get off the water...if it is not airborne by the third bounce, you are in big trouble. It is a high performance float plane and needs to be approached as such........
    All I ask is for a chance to prove that money can\'t make me happy......

    RE: Supermarine on Floats- Need help!!!

    Hey ive recently purchased the plans for the S6B by jim pepino can anyone give me some idea as to what engine would be adequate for it i was thinking somewhere along the lines of an 8hp mvvs single cylinder engine but i dont know, also would it be a safe bet on sheeting the underside of the floats in aluminum of some sort? cheers

    RE: Supermarine on Floats- Need help!!!

    Maybe you could have a look here;

    http://www.kitcutters.com/Pep/PepSupermarineS6B.htm

    It could be the 85 in variant ?

    Im very interested in the total weight of your plane? That will be a deciding factor on the engine.

    Im in the process of ordering the 85 in variant myself.

    Hi Kwik,

    I believe the Jim Pepino plans show a Quadra 35cc engine. Most likely a 50 to 75 cc gas engine will give you plenty of power to handle the 85" S6B. I would guess that the 85 inch S6B would weigh in the neighborhood of about 25 to 30 lbs ready to fly. A large scale float plane has to be well built to handle the harsh loads from water landings that are greater than what you would expect in a land plane.

    RE: Supermarine on Floats- Need help!!!

    Thank you Carlos. I have a G-62 for it. Probably a good choice?

    People talk about using non-scale floats.....So how to get drawings for "non-scale" floats, I wonder....

    I ordered drawings and a fullkit from here;

    Hi

    I have flown various schnieder type planes, They pretty much go where there pointed if you have flown other low wing planes then you should be ok.

    They don't like to be slowed down, and if the engine stops won't glide to well.

    Carlos G,

    I would be very interested in knowing more about the Kenny Bundt molds for the Supermarine S6.b. I saw Kenny at the Schneider Cup Re-Enactment in Lake Havasu and I know there would be people interested in a fiberglass airplane rather than built up. I would be more than happy to post it on the Schneider Cup Website... www.schneider-cup.com

    Carlos,

    Have you built your Supermarine S6b yet? If so please post pictures and details. Are fuselages and floats available to purchase? Let us know
