Christopher,
Thanks for your interest in our Top Flite model. The Razorback is scheduled for release in June. Pre-orders are usually available within 2-3 weeks before release so check with your local dealer to get one of the first arrivals.

Thanks from your Hobbico Airplane Team!
If they are releasing it in June it will probably be demoed at Joe Nall

That would be the perfect engine! I hope it will fit

According to my checks and a friend who has this engine and the p-47 cowl says it will fit.

The cowl has the following measurments at the thrustline according to another post on RCSB:

It is 8.75 inches (222mm) on the horizontal and 12 inches (305mm) on the vertical.

20x10x4 has been used on the Top Flite G.S. P-47. On a DLE 55, it turned 5500 rpm on the ground. It didn't really seem to unload in the air much. With a G-62, it tached at 6000 on the ground but hasn't been flown yet due to the weather. I suspect an EME 60 would turn it fine. Several guys at my field use that engine with a 24x9 and it pulls like crazy.

Thanks Lifer, Im thinking maybe the 20x10x4 is a bit to much for the fg-60 and maybe a 19 inch is more correct..will have to see. The engine has been reported to pull an APC 22x10 at around 6800 static though and these radials are prone to be more "torque happy". I guess we will see.

Check YouTube for a guy named Affas flying a P-47 with a 4-stroke engine and a 19x8x4 prop. It flew pretty good.

Yes I know, he is my friend but had forgotten about that video as it is a couple of years old...and I think it is an 18x10x4 actually, but you are right it looks to be sufficient power.

Lifer,a 24x9 does not leave much much ground clearance. Is that prop used on a TF P47? I have to be ready on the elev. with a 22X10 .A flying buddy is using a 24 on his TF P47 with a DA85 has had expensive brushes with the ground on take off.

flypilot....It looks like you have done your homework and it will be the perfect engine!

I wasn't too precise on that. Apologies. The prop was on a 3D type plane.

I fly a 24x14 on my P47 and I have no problems with ground clearance.

Does anyone know if the Saito FG-60R3 will fit without cutting the cowl?

On the FG60R3 thread there is a TF ARF p47 bubble canopy pictured without cutting the cowl.It uses the same cowl as the razorback.

I have the new version of this engine and it has been broken in, I have wanted a plane to put this in. I have no warbird experience, l fly sport planes and heli's. I have read that this plane has some trainer like qualities. Is this a good first time plane.
thanks

TomH,

My advice to you is hook up with an experienced Warbird flyer. That will save you a lot of time, money and heart ache.

It is a very easy plane to fly and take off and land ... U have to bring the power up slowly on take off and keep the speed up on landing and carry a little power. Landings are all about nailing the speed envelope, At least that's the way mine flies. Good Luck and let an experienced war bird pilot maiden her.

Something else to consider; Set up your favorite sport plane so it has the same wing loading as your warbird project plane. Add the necessary weight to the c/g then practice landing with your sport plane to gain experience with a similarly loaded plane.

Most sport planes and trainers land with nearly zero ground speed but warbirds land much faster. Practicing with a plane set up as above will help you with the transition.

It helps!

All said above is good advise....and the TF P47s are the easiest giants to fly.

There really shouldn't be any surprises. The design has been around a long time. I reviewed the manual and it looked like they revised the air tank mount and of course with the top hatch you can hide all the switches, etc. I can't justify buying a third T.F. G.S. P-47, but I expect it to be very popular.

great advice lifer, I will try to calculate that out and use one of my 3D planes as the test setup.
