How's the Model Tech P-47 Razorback?
 

I did a search on this plane. I read a bunch of posts about this plane dated from July throuh Chrismas of last year. Seemed like everyone was trying to buy one, or just received it at their door, or only had experience with other warbird models by this manufacture.

Well, I'm hoping by now some of you folks have had a weekend or two to construct this ARF since last year, and MAYBE NOW YOU CAN TELL ME HOW THIS MODEL TECH 67" P-47 ACTUALLY FLYS?? :confused:

Mainly, I'm looking too see if it's got a lighter wing loading and might even fly a little easier then some of the other warbirds in this size offered out there? I hear it has no flaps too?

Floater
 

I am also building one right now, but one of our club members has flown his (I didn't see it) and I heard that it is a real floater; took almost the whole asphalt runway to get it down at idle. It seems pretty light to me, of course I won't know until everything is together. Putting an OS FS 91 in mine.

Here's my buddys
 

It's gonna maiden next weekend. Engine is a Saito 100.

Sure looks great. Let us know how it goes.

Yes please do let us know how it goes! I'm planning on buying one next.

How was the building process for you?

just subscribing to the thread
 

mine's on order for this week... looking to hear from those in the know.

The only thing I don't like about this ARF is that it comes with tiny 2-1/2" diameter main wheels. Come on, this is a relatively large .60 size warbird, so the main wheels have to be at least 3-1/4" in diameter. Look at the smaller Kyosho warbirds like the P-51D, the Zero, and the Corsair for instance. They all come with nice 3" diameter main wheels.

I'll let ya know
 

how it goes. I didn't build this plane. It's a fellow flyer at our field. He's going to maiden it this weekend coming. The plane looks nice!!

I Flew the P47 Yesterday
 

I would like to thank my buddy blackdog for posting my plane.
It flew very nice. It had flying characteristics.
Prior to flying it I had to add 8 oz. of nose weight.
I'm going to add larger front wheels to it. This is because I fly on a grass field and it does tend to nose-over when taxiing.
I found when on grass if you gun it on take off nose overs are not a problem.

It's low speed flying characteristics are very good and low speed landings are not a problem.

The Saito 100 is a good fit for this plane. It flew a bit faster than scale.

If you are into war-birds, you will not be disappointed with this ARF.

FightingIrish,

That's a good report. Sounds encouraging for those considering a purchase.
About your having to add 8 ounces of nose weight:

Hmmmm.....sounds like it might not be a bad idea for us prospective buyers to check which engine weighs 8 Oz more then that Saito 100 you had in your plane, and put a heavier engine in there (if it will fit in the cowl descent) and provide some extra power to boot.

The YS 91FZ is a perfect engine for this plane since it is heavier than the Saito 100 and fits nicely inside the cowl.

I went with the saito 100 for a little extra power. Since it is just a little larger in size than the saito 91 it fit very well inside the cowel. This was the only reason i did not go with a saito 120.

Sure, you can get larger front wheels for it. The main concern is whether or not you need to modify the wing, like cutting out ribs, in order to fit larger front wheels.

How's the Model Tech P-47 Razorback?
 

I have a set of 2 3/4" wheels from a previous plane. Before I investigate whether I need to modify the wheel opening I'm going to taxi it around with these wheels. If it does taxi well, I will remove the plastic wheel well inserts. When I first assemble it I thought there was enough room for this size wheel. I will just need to rebuild the wheel well opening.

If all else fails I will either fly it as is or use the fixed landing gear.

I'll let you know how I make out.

any update on the wheel situation. I'm picking mine up soon and am hoping to hear...

Does anyone know what the real "scale size wheel" would be for this play... It's 1/7 scale i've been told. so i figure the 2.5" is way to small... should it be 3?
anyone know the size of the full wheel on a REAL jug?

How's the Model Tech P-47 Razorback?
 

I don't know where they come up with 1/7 scale, I'd say it's closer to 1/8 or less. The bigest I wheels I thought I could fit without modifying the wing was 2 3/4. I had to make up some wheel wells, the stockers are small like the wheels. I found it still wanted to nose over, partially from the small wheels, and partly due to the landing gear being a bit weak on the stock retracts. I shimmed up the back of the retracts to angle the gear forward a bit. It helped. I had a bit of a hard landing off field when my motor died, so I have a little work to do before I fly it again. Keep that nose weight in mind when putting it together. Get the weight forward all you can.

RE: How's the Model Tech P-47 Razorback?
 

Hi Fighting Irish, I have a Saito 120 in my CG chipm and want to transfer it to a Model Tech P47 - Do you think the 120 is too big an engine for this plane. Assuming I would change out the retracts and balance a bit better.
Thanks

RE: How's the Model Tech P-47 Razorback?
 

I sold mine to a guy who put a Saito 150 in it. Seemed to fly fine. Might want to beef up the firewall some, and exercise good throttle management.

RE: How's the Model Tech P-47 Razorback?
 

If my figures are correct the YS .91 and 1.10 are about twice the weight of a Saito 100, that's about 19 oz more. Seems a Thunder Tiger .91 will get you an extra 6-8 oz and have enough power. Engine would cost about $100 less than the Saito and about half as much as the YS 1.10.

I know the TT 91 can't compare to the YS in power, but should be close to the power of the Saito 100.
