hey guys i just baught one of those model teck jugs and i am going to be mounting an O.S. 60 in it...i dont know if it will pull it very well and i dont know how much nose weight will be needed do u think that im making a wise choice with the .60 2 stroke...thanx

rc34074,

The Slimline inverted Pitts muffler on my Saito 91 puts out a very mellow sound that sounds a lot more scale than a two stroke would. I am sure that you muffler makes the two stroke sound a lot better, but to me, four strokes just sound better on warbirds

BluuesBrothers4Life,

I think the 60 would make your jug under powered. Sometimes you need that extra power to pull out of trouble. I tend to go with the max recommended and it has saved the plane on occasions. My 2 cents.

Jim

rcjake- we all have our preferences and i acknowledge your preference for the 4 stroke. mine is for the 2 stroke. hey- i fly with guys who like 4 strokes- see how tolerant i am . in fact my buddy doug who also flies warbirds uses 4 strokes. if you ever get to ohio come by our field- its pretty decent and we have nice open approaches for those flap down landings, even for the big ones.

Hi Ed,

I fly 2 strokes, four strokes and gas burners...I like them all. Hey, I even have a couple of electrics!!! Diversity makes this hobby interesting and keeps these threads hopping.

It will be a while before I can make it to Ohio again. My ex-partner & I had a booth on the main floor at the Toledo Expo for 5 years when I lived in Illinois. I was also able to attend the AMA National Flying Site Grand Opening and the following Homecomings.

By the way, If you can make it to Phoenix this week-end ( BG ), my club is having a Scale Fly-In and I am the CD. You can check out our flying site by going to:

www.ampsrc.com

The temp forcast for Phoenix for the week-end is in the low to mid 70s. It is tought to take sometimes...

Well RC Im so confused on which engine to put in my Jug, four or two stroke that I went ahead an ordered the davis diesel head for my ST G-90. That should give me the sound + power to pull her around. I already had an extra G-90 so all I had to buy was the head, cheaper then a new four stroke. Hope it works out.

I THINK THAT IF YOU USE A .60 IN YOUR MT P-47 YOU WILL NOT BE HAPPY WITH IT'S PERFORMANCE AS A FIGHTER.I HAVE THE MT P-47 ALSO AND FLY THE HELL OUT OF IT WITH A GREAT RUNNING AND SOUNDING MAGNUM 4 STROKE.FIT GREAT INSIDE COWL MOUNTED ON IT'S SIDE WITH EXH POINTED TO THE GROUND.A LITTLE CUTTING OF COWLING FOR ENG VALVE COVER AND ON BOTTOM FOR EXH STACK.ALSO VENT THE REAR OF COWL TO VENT HEAT. ONE OTHER THING THAT YOU SHOULD CONSIDER IS TO USE LARGER WHEELS ON MAIN GEAR.YOU CAN CUT THE WHEEL WELLS EASY ENOUGH TO ACCOMMADATE. PROVIDES A LITTLE MORE CONTROL IF FLYING OFF GRASS FIELD AND LOOKS BETTER. THE MT-47 ALSO LOVES TO NOSE OVER ON TAKEOFFS SO REMEMBER TO HOLD FULL UP ELEVATOR UNTIL TAIL COMES UP AND YOU GAIN ENOUGH SPEED FOR ROTATION.GOOD LUCK,GIV'M HELL

I have this plane with an OS1.08 in it. It pulls it around nice. Its not a missle but very scale. I own 2 G90s. One is in the GP Shoestring. great engine but if you think that G90 is going to pull that Modeltech, your sorely mistaken.
Mine weighed in at 9 3/4lbs with that engine. Your looking at least 9lbs with your 90. Isn't gonna happen. If cost is an issue go with the Magnum 1.08 or if not, stick a 120 fourstroke inverted in it. other options are the 120 Thunder Tiger, Webra etc. A .90 won't do it. later

It looks like alot of people are running the Magnum 91 four stroke with the MT P-47 so I just ordered one today, they are on sale for $169.00 at Hobby People. I am going to put my G90 in my Seagul Edge 540.

I installed an O.S. 1.20 FS in mine. The only cutting on the cowl was for the exhaust and for the airflow exit, which needs to be done regardless of which engine you choose. The engine pulls the plane with authority and sounds great also. I'm sure a .91 or 1.00 would work just fine, but you will have to add dead, unusable weight to the nose to get it to balance. The balance issue is the main reason I went with the 1.20, usable nose weight.

meataball1,

Did you use anything to replace the supplied wheel well covers after you enlarged the holes? I would like to enlarge mine but I haven't figured out what to use to replace the wheel well covers. I really don't like the idea of leaving the well open. I'm affraid that oil from the exhaust and dirt may get up into the wing. I nedd some advice.

Thanks,

John

HI,JOHN NO I JUST USE THE COVERS THAT CAME WITH THE KIT. TO MAKE THE WHEEL WELLS A LITTLE MORE NEATER LOOKING I USED 7-11 PLASTIC COFFEE CUP RIMS (CUT THEM OFF ABOUT A INCH AND FIT THEM IN THE LARGER WHEEL WELL,ALSO WILL HAVE TO CUT TO FIT OUTSIDE DIAMETER THEN GLUE IN PLACE) ANY EXPOSED RAW WOOD WAS PAINTED TO PROTECT FROM EXHAUST OR OIL PENETRATION. MEATBALL1

This is just a thought, but instead of adding a heavier and bigger motor, couldn't a guy just put the battery in the engine area? I ballanced a biplane like that and it seems it would fit up there just fine. Four strokes get hotter than twos but it wouldnt be a problem to mount a battery to the other side of the motor mount.

I could be totally wrong but I enjoy these posts because it will probably be my next plane. I opened up a box last week at the store and I thought the plane looked really good... better than I could build anyway! If it flies as gentle as everyone says, I may pick it up in a few weeks.

Anyway, has anyone ever moved the battery that far foreward and would it work?

Paul

HI PAUL ,YES YOU CAN MOVE YOUR BATTERY FORWARD BEHIND FIREWALL AND WOULD RECOMMEND USING A SECOND BATTERY TO BACK UP YOUR PRIMARY BATTERY IF YOU ARE USING A RETRACT SERVO (IF RETRACT RODS ARE NOT SET RIGHT,THE SERVO WILL IDLE CAUSING A DRAIN ON BATTERY)SO THIS ALSO HELPS WITH NOSE WEIGHT. JUST GOOD INSURANCE! IF YOU DECIDE TO USE A SECOND BAT YOU WILL ALSO NEED A SECOND SWITCH!

the magnum 91 will have less performance than the g90. it certainly will fly the p47 but the g90 would be a clearly better choice, regardless of the amount of weight to be added.

however i would still recommend a 1.2 2 stroke or similar engine over the tiger, if its a halfawy decent 2 stroke.

ed

behind the firewall? no, I mean in front of the firewall mounted to the motor mount. 8 to 10 oz. of weight is a lot.

I did that on a little bipe I have and it worked like a charm. When I see photos of that ship with its cowling off, it looks to me like a guy could just put his battery way up there and add no extra weight.


again, just a thought

I've never heard of anyone doing that, but I guess it could be done. Seems like a little trouble though. Adding a larger motor is ideal in this situation. Sure, it's heavier, but it's more powerful. The only drawback I see with your idea is that the battery is going to get nasty with oil and the wires will be somewhat exposed, which in my opinion is not a very good thing. I'm with meatball on this one, right behind the firewall would be as far forward as I'd go. If you need more weight after that, you'll probably have to add some lead. Good luck.

Meatball,

I'm sorry. I misworded my request. I said wheel well covers instead of wheel well cups. I don't use the covers, but what I was needing to know was what you used for new wheel well cups. Your reply answers my question. What did you do to the covering on the edge of the well hole to keep it from being pulled loose by the airflow over the wing? I'm sure that ironing it down will help, but I'm not sure if just ironing it down will make it stay put. What did you do here?

THE TOP OF THE CUP HAS A RIDGE ON IT THAT WILL SEAT ON THE EDGE OF THE NEWLY CUT WELL AND WILL SEAL THE COVERING WITH SOME CLEAR SILICONE . THE APPLICATION OF SILICONE ALSO SECURES THE CUP RIM TO THE WING.

Meatball,

Thanks for the info. I'm not too good at home remedies when it comes to airplanes. I think your fix is going to work well for me.

Thanks again,

John

Meatball1, I have the crap covering off my wing now and am trying to modify it for 3" dia. wheels. Did you use the stock retracts? I got a tip on using 1/16" sheet balsa, wet it and bend it around for the wheel wells so I am going to try that. I think that would look great painted.

SKYKING 424 , I AM USING THE STOCK RETRACTS THAT CAME WITH THE KIT. THE 1/16 BALSA SHEETING IS ALSO IS A GOOD WAY TO GO SINCE YOU ARE RECOVERING THE WING.

(I have the crap covering off my wing now)

Skyking,

What exactly are you talking about?

John

Yard. I am going to recover the wing on my P-47. I don't like the covering that is on it ( too thin ) and I wanted to try and install larger wheel wells.

Those of you that don't mind the plastic wheel wells can use the same ones used on the H9 P-51. They are made the same as the ones in the kit and will allow up to a 3 1/2 inch wheel. I had to buy a new set for my P-51. If the P-47 gives me trouble I'll change them out. Horizon sells them for less than $10.

Jim

Thanks for the info on the wheel covers Biker I will check them out.

All you guys that have commented on the ST 90 can you please tell me your preferences for FUEL ie 5% or 10% and also glowplug and PROP.. I have heard people running APC 12x9 to 13x8 to 14x6 So which is the best for all around performance???
... I have 2 of these ST G 90's NIB and am going to install one of them sidemounted into a 60 size corsair and I have to buy another so I can put 2 on my OV-10 BRONCO...
Thanks for your time....
