RE: Engine mount
Hi! That engine is one of the most powerful .46 engines on the market. Very good engine and reliable too! But get a Dave Brown plastic motor mount for it! The alu mount you showed us is no good! Just take a round dowel and stick and glue that inside the motor mount holes you now have and then Ca glue (spot glue) the new plastic mount where you want it. Then drill holes with a long drill bit through the motor mount holes into the fire wall and then remove the mount. Redrill the holes a little bigger and put in four blind nuts. Secure the blind nuts by screwing in 4mm allen head bolts. Then take the mount and fasten it to the firewall with long 4mm allen head bolts!

RE: Shoestring battery removal????

Shoestring battery removal????
Hi! Been involved in Pylonracing for the last thirty years and are now going to try electric pylon with the Horizon Shoestring. But I cannot for the life of me understnd how the battery should be removed/changed in the Shoestring. When I push the motor cowl rearward as much as possible to get a good fit against the wing and canopy I cannot push the canopy forward so I cannot remove/change the battery? The small indentation in the front of the canopy is covered by the motor cowl. And as such I cannot move the canopy forward to release the taps under the canopy floor.

RE: EIII Restoration
Hi! -2 degrees on the stab is no good! Set it at 0 degrees to ther wing. The wing could be anything around 0-+2 to the fuselage centerline! At this position the engine should be pointing slightly down. Try to reduce elevator trow as much as possible and at the same time move the CofG backwards...byt not too far back. Sounds as if the plane is nose heavy.

RE: Tuning with your snoot up in the air
Hi! Holding the nose of the plane straight up to check the setting is what I do and have done for the last 38 years when checking an engine. But the pinch test is no good! Too crude! Much better to just tune the engine by turning the high speed needle and listen to the engine.

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: 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: 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.

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.
