RE: OS 1.20AX Unexplained Flameouts.......>>>
Hi! The reason Taz and others have problem with their engines is that they use aftermarket Pit style mufflers with too large out let holes and too little volume! All OS engines (and all others too) run perfectly good as long as you treat them right and follow some simple rules. 1. Always mount the engine and tank according to the "tank mounting rule"! 2. See to that you have enough cooling if you mount the engine inside a cowl. Just taking up holes is not enough!!! You have to stear the incomming air around the cylinder tightly. 3. Use the standard silencer first and set the engine right so you see that everything works ok. Then you can try it out with a aftermarket silencer. If it doesn't work out ok you know that it's the aftermarket silencer and not the engine. 4. No modern engine needs 10 hours running in time. Just a few tank is all it takes to have a perfect running engine. 5. use 5-10% nitro fuel! 15% is a waist of money! 6. Use an OS 8 or Enya 3-4 glow plug! No OS F plug is needed! 7. Use the right size of tank! In Taz case a 16oz tank is ok. 8. Use the correct size prop, in Taz case a 14x8,15x6 or 16x6. 9. And most important! Set the engine a little on the rich side to compensate for loss of pressure as the fuel level drops during flight.

RE: Nooks and crannies.
Hi! Easiest is to prep and paint before you mount the flaps. You don't have to glue anything except the hinges.

RE: triple blade prop question
Hi! All OS engines are dead reliable so you cannot go wrong with the OS .15 LA engines. But I agree that four strokes sound better. OS .30 FS are an alternative, though a little on the heavy side compared to the .15 LA engines. HP is no alternative as they are not as reliable as the OS engines and they are also heavier and does not sound good compared to ordinary poppet valve four strokes.

RE: Catalina Kyosho PBY Seaplane - Advices
Hi! My two Catalina kits did not have landing gear as the later kits had. If you are not going to fly from water you could make your own landing gear (Semi scale) from 2-3mm piano wire that you bolt to the sides if the fuselage.Some reingforcements to the fuselage sides is necessary in that case though.

RE: triple blade prop question
Hi! A 78" four engine plane will be much over powered with .40 four-strokes. Belive me. My 211cm span Marutaka DC-3 is powered with two OS FS.26 engines swinging three blade 10x4,5 carbon fiber props and the performance is very good. If I were you a would use four OS .15 LA engines swinging 8x5 APC propellers.

RE: Twin .61 prop question
Hi! .61 engines on a Marutaka B-25:..? Way too much power /weight! You will have pattern plane if you choose those engines and not a warbird! Better use two OS .40-.46 LA engines.

RE: prop size
Hi! I'm certain that if you tried some Graupner Sonic or RAM...or even APC props in the range of 12x6,13x4, 13x5 you would see better performance than those 12x6 3-blade MA props.

RE: OS .60 FP Bushed engine suddenly dies
Hi! The first thing you should do when you encounter an engine like this is to replace all things that isn't original. In your case it's the silencer. The silencers volume and outlet area means a lot to how an engine behaves and runs. So replace it with the original OS silencer. A change to another carb will not do any good as the original is as good there is. Some additional advise. Fuel: use 5-10% nitro and 20% castor oil ,or a mix of Castor oil and syntetic. Do never use more nitro than 15%! Glow plug: Use a OS 8 or Enya 3 plug! There are imany otjhers that works eually well but these are the old stand byes! Fuel tank: Use a 10-12 oz tank.Not larger. And mount it according to the "Tank mounting rule", preferably using a two clunk system (Uni-Flow). Prop: 12x6 or 13x4 or for a very slow flying model 14x4. APC , Graupner Sonic or RAM are the best available.

RE: Catalina Kyosho PBY Seaplane - Advices
Hi! Of course we have. 13 years ago I put togheter two of those Catalinas, one for a friend and one for myself. Both were powered with OS .15 engines, one using FP and one LA engines, and APC 8x5 props. Both took off from water easily and both flew (fly) exceptionally well; I still have mine. I did some modifications to both models to have them more scale like. What I did was rasing the wing slighly to have the wing sit at a more scale like position. I raised the wing 6mm by adding plywood and 24hour epoxy/micro balloons to the wing sadle.But only to raise the front portion of the saddle.I did not put anything under the rear part of the wing saddle. I also used only one throttle servo and replaced the heavy wooden side and elevetor wooden dowels with thinnest possible fishing steel wire (pull-pull sytem) , also took up some lightening holes on the underside of the wing to make it lighter and at the same time replaced the thick heavy wing covering with silver Oracover plast film to make the Catalina look like a version used in the Swedish marine airforce in 1951 (the one that was hot down by Russian MIG 15 in the Baltic sea). So it is vital that you make it as light as possible! I use the original C of G position. Rasing the outer pontoons will not work! The best I can think of is doing as I did by raising the wing up front, by making the wing sadle 6mm higher up front and replacing those 8x6 props with 8x5 APC props.

RE: Twin .61 prop question
Hi! You cannot use counter rotating props as the engines you have choosen isn't available with reversed rotation crank shafts. Soo...use ordinary rotating two blade 12x6 props (RAM, Graupner Sonic or APC) or if you want less performance 3-blade 11x6 MA props.

RE: Help on engine cowling?
Hi! Those would not hold it long! Problem is vibrations. A much better way of holding a cowl is doing it like this. 3mm epoxy plates glued (24 hour epoxy finnishing resin and cut glass/carbonfiber ) inside the cowl using four metal screws screwed into the firewall. The cowl is secured through the front using a long screw driver.

Hi! If you want to fly like the real CUB does on the wing and have relaxed flights...use a OS LA .40 and a 12x4 prop. If you want to fly it overpowered and totally distroying it's good flying characteristics... use a larger engine.

RE: Got my wings, what now?
Hi! It has all it's weigh above the wing at inverted flight! That's making it more demanding for the model to remain in position. That in conjuction with that you do not have a symetric airfoil makes it slightly harder for the model/you to maintain inverted flight , but it's not that hard in comparence to flying a low winged plane.

RE: What to use to hold screws in?
Hi! The ASP .40 or Kyosho .40 GX (same engine) all use 3mm screws to hold their carbs. I have on several occations retapped the hole to 3,5mm and used blue tread lock to hold the screws. Tread lock is not necessary to use on the head bolts! If those get loose it's asign of running too lean (to much heat).
