hi
did any one fly a pica 1/5 scale mustang with an OS BGX?
what do you think of this combo? do you have any advice for
a maiden flight?

thanks

I have witnessed the TopFliite 1/5 scale P51 fly with the BGX for power and another with a G62. I am sure the kits are similar size and weight. The BGX powered version flew well but ran out of steam on the pullups, the G62 was impressive, it moves out never lacking for power or performance.
The BGX is a cleaner installation, wear as the G62 has the carb outside the cowl. Pesonally I would go with the gas version for power, reliability and a buck something a gallon fuel cost.

I fly the TF P-51 Giant Scale with the US 41 and an 18 X 12 prop. The 41 will fly the plane but it looses power quickly on vertical climbs. Go with the gasser G62 in you PICA and I'm sure you will be happy. My 2 cents.

I flew a Pica 1/5 scale Mustang with a Super Tigre 3000. It flew very well until I landed inverted at about 100 mph. With no damage to the wing and only minimal damage to the fuselage (it was gone from the front of the canopy to the bottom of the firewall) I decided to rebuild it. In the rebuilt aircraft, I decided to install a G-62. This was not a mistake. The aircraft had more authority over the top and flew like you would want a Mustang to fly. The entire aircraft, with retracts and G-62 weighed in at 26 pounds. I flew it off of grass and concrete runways and with flaps at about 25 to 30 degrees, it would land nose high without any tendency to stall. It was truly a great flying warbird. I would love to have another one. The rebuilt met its end at a fly-in when for no apparent reason the aircraft went failsafe lockout and spun in from about 250 feet. My personal opinion was that someone turned on a transmitter on my frequency, but who knows?
Anyway, if you are wondering if the Pica 1/5th scale Mustang and Zenoah G-62 is a good combination, take it from someone that flew just that combination for about 2 years and loved every moment of it.

Going gas does not mean you need to hack the cowl like mad! have not seen a clean G62 on a 1/5 scale mustang/spitfire. If your willing to make necessary changes to the engine mounts, I recommend the 3w50. I have one of these and it has the same power on my Brison 3.2

You can get the 3w50 entirely in the cowl with a wrap around inverted pits style muffler. The rear carb makes helps keep the clean look also.

One way to hide that G-62 better is to mount it farther back in the fuselage. This requires a longer prop hub which we have used with good success. RCIgnition can make one for a reasonable price. The G-62 is a simple, reliable engine and if you use it you will not have to add lead to the nose. Mine balanced out fine with two battery packs installed near the firewall. If I had to build another one, I'd install another G-62.
By the way fw190, let me see your Mustang.

FW-190 - on your 3W 50 - did you have any trouble getting at the needles using the pitts muffler?

You guys can take a look at my installation for my Spitfire on my website.

I have a Byron Mustang that I have tried fit the 3w50 with a JA wrap-around muffler. It fits well without cylinder head cutouts to the cowl. You will not benefit from prop extensions, it will only induce more vibrations and the G62 is already a shaker.

At 80"-90" warbird, you won't need more than a 3.0 ci engine, unless you want jet like speed... IMHO

The Spitfire is 83" span. The only engine part you will see is the silver spark plug cap.

No dought the G62 is reliabilty, one of our flying buddies flys with a Corsair, day in and day out without any problems. Very good engine for a P47, Corsair... something with a big cowl... IMHO.

I am not recommending 3w engines, its just from experience...

You can try other engines that are comming or already available such as

Aerotech's new Gas engine for their highly fab P51.
Morris Hobbies will come out with a 50 rear carb.
ZDZ will have the 50 or 60 rear carb.
Dessert Aircraft will come out with 50 but I think its a side carb.


These engine will have cleaner installation... you'll appreciate your scale warbird a lot more when you see it in the garage as well as it is in the air.

If you see the engine sticking out during a low pass, then it takes away the scale appearance, but if your running a 100ci on a 80"-90" warbird... then you may not see it LOL

Fw-190 - here's the new install on my GSP P-51 (96"). I just wondered if you had a work around to deal with the carb needles?

I also am powering my TF P-51 with a 3W-50. It does fit nicely within the cowl, the only drawback is adjusting the engine. There's really no way of getting to that carb unless you hack the top of the fuse or set up some type of compartment that can be removed if need arises. I love that power though....ooh baby!

warbirdz1

Sabre....I also have the T/F P-51 with a G-62....not going to "TOP GUN" anytime soon so at low passes @ 105mph hard to see carb sticking out of cowl.......plus its just that much easier to adjust if the need arises.....I use this plane to keep up on stick time so I wasn't as concerned about "Aesthetics" as some one else might be....if you just want to fly a G-62 just might be the ticket....If your concerned about "Looks" then quite a few good suggestions have been made....either way its a"FUN" warbird to fly...My 02 cents worth....Bill....

Since the engine is inverted the adjustment screw are accessable underneath. I use a fuel line over the adjustment screw and it helps guide my small flat screw driver. The GOOD part of this is that you can adjust the the high end and the low end without shutting the engine off ( just make sure you have someone help you hold the model). This is impossible on my Brison 3.2. So I have to do the start, try, start try method, not easy.

I have also heard that you can use fuel line with a brass/aluminum tube extension connected to the Low and High end needles and this can be accessed from the outside. This way it does not have to be a straight shot but with a small bend to the fuel line is fine.

Hope this helps.

It a personal taste that I prefer not to see the entire engine on a nice looking model.

Which engine are you using on the 98" Giant Scale Plane???

My Feedback: (1)

Gentlemen, If you install arrow shafts to the needles when building and installing rear induction engines, there is no problem adjusting them. Regards G Also if you solder a cut off socket head bolt to each needle alignment can be offset and you can use a ball driver to adjust!

Capt G

My Feedback: (8)

Thanks guys but the needles are UNDER the muffler. Oh yeah - it's a 3W 75i.

fw190

My Feedback: (37)

That 75 should give you a big loop for that mustang. What is the wieght on the plane ready to fly?

Ok All,
Since you are reading this I suspect you are interested in engine size in the 1/5 scale P51. Here are some Mfg suggestions that confuse me even more... I am going to build a big P51 eventually so I always have my ear to the ground. What is your comment on the following...

Pica - 1/5 P51D TF - 1/5 P51D TF - 1/5 P51B
Weight - 20-22lbs 18-23lbs 18-23lbs
Fuse - 77.5" 73.5" 73.5"
WS - 89" 84.5" 84.5"
Wing Area - 1356"^2 1245"^2 1245"^2

Ready for the suggested engine sizes...

Gas - 35-41CC 41-70CC 30-60CC

Could someone please tell me why the big spread. The Pica is actually bigger and they call for a smaller engine. Thanks for looking.

Like the Nosen, the Pica Mustang has been out for a long time. Back in the old days, when all these gas engines were not available, some of these large aircraft manufacturers would advertise these aircraft could fly with a strong .60, I know Nosen did. So if you wanted to build a Mustang from a Pica kit, keep it as light as possible and monokote it, and do not install retracts, it would probably fly on a 30cc engine and weigh under 20 lbs. Now when we cover it with fiberglass, primer, paint, all the details, retracts, etc. then we end up with a 25lb airplane and there in lies the need for a 60cc engine, if you want any performance at all.

Capt G

I'm hoping for around 25 lbs. Still a lot of work to do but here she is on her feet.

Excellent explanation Fighterpilot! It makes perfect sense and I thank you for answering a very nagging question.

Isn't that an ARF from Giant Scale Planes? If it is, it should come in under 25lbs and fly very well with an engine in the 50cc range. Try to purchase one that is smooth running because on those ARF's you just don't know how strongly they are built. Good luck and good flying.

Sabre,
I had a yellow zero with a weight of 25 lbs with an OS BGX. It would take off from grass in 150' to 200', climb steadily at a 30 - 40 degree angle and loop from level flight if you entered the loop at a reasonably high speed. I would assume that your Mustang would perform similarly.

Thanks you all for your replies.
My Mustang weighs 19 bounds. and will probably fly it in two
weeks time. it will be my first giant scale, and i hope I will write back good news.
