Just got my kit and am SUPER-excited to finally build - really build - a kit again!!! [sm=49_49.gif]

I've been an IMAC guy for a while and so am infused with the 'lighter is better' mindset which makes this project all the more unique. I'm building a plane where I need as much weight in the nose as possible....

Soooo....What engines do you folks recommend? I'm putting a couple servos in the tail and know how to use the throttle (as in there are more settings than idle for full) so I'd like to get something big up front. What's the concensus here? Zenoah? Quadra? DA???

Hey Pappy, the Zenoah G62 would be perfect for the TFGS P47. I have the TFGS P51 with a G62, and I have a friend with the P47 with a G62 and it is a good combo. They are very reliable and make good power. Good Luck, Kevin.

I agree, a g-62 is perfect for the 47, that's what I fly in mine and it has a surplus of power here at 5,000 feet. One note of caution!
The IMAC flyers I have seen who build their first warbird have that LIGHT IS BETTER attitude. That usually stops on the first hard landing when they have to repair the landing gear mounts! A twenty four pound P-47 is not an IMAC plane and needs to be built more sturdy in order to withstand normal flying, Wing loading is much higher than the normal IMAC plane and you will never be able to get away with the things an IMAC plane does, especially on take off and landing. My suggestion is to build the plane per the plans, down to the last detail and you will have one great flying warbird.

Larry,

That's exactly what I'm doing. I'm going to F/G and paint the beast so there's goes the 'light weight' thang right there! 8-)

The only thing I was hoping bring over from my IMAC mindset was more power than needed. For scale-like take-offs, I can do a part-power accel. I'm a big believer in having excess-power in my pocket just in case. Does the G62 have enough power to do that?

crashproof

Pappy the G62 has plenty of power it will fly the plane quite well at half throttle but this plane may come out at around 30 lbs and you will always want full throttle and max ground speed for takeoff. Accel slowly right rudder to keep it straight tail comes up full throttle for takeoff speed then ease back on the stick to climb out. I have a video in the members section of the TFGS P51 with G62 that should give you an idea of what the G62 might do. Good Luck, Kevin.

Pappy..
i have been flying a TFGS Jug for four years....at 23.5# A G-45 with a 20-10 XOAR will fly this plane fine, with a reserve safety factor....However, since the G 45 and the G62 are close in size, and share many of the same parts, either would be a good choice for your Jug... Both fit inside the cowl, except the carb opening. You will love this big bird, smooth flyer, and lands as soft as a lady with a baby.... If you would like a pic of my plane, I will need your Email address....

Do you need to open a hole in the cowl for the carb? That's a deal-breaker right there.

I have been flying my P-47 with the G-62. Plenty of power, and I did not need to add any nose weight. I have attached the link to my first flight video using the G-62. The engine is perfoming well, even better now after about 15 flights. Hope to have more video soon.

I did make a hole for my carb. Not to noticeable. Have attached a pic.

Thanks for taking the time to post the link. Can't view Youtube from here but will check it out when I get home.

Here's one I just found on RCUVideos: [link=http://www.rcuvideos.com/item/4CZ5LD6RXGX1GY1W/theater#theater_title]G62-Powered TF GS P-47[/link]

Seems like it's just right.

Beautiful job Canuck!!! Is that the ABS cowl or one from Fiberglass Specialites? What kind of servos are you using?

I am using the ABS cowl that came with the kit. I rienforced the insides with fibreglass just to toughen it up. Also ran a bit of carbon fibre strips along the length where the mounting brackets attach. I am using Hitec HS645MG servo's throughout.

Pappy-

I am trying to finish mine up that is Fiberglassed and will be painted. I'm an IMAC guy also. I put a 3W55i in mine. If I had to do it over though, as much as I love 3W engines, I'd put a DL-50 in it. Costs less and I wouldn't have had to cut the firewall hole for the carb. No cutting of the cowl was necessary though. My friend is building one at the same time with the DA-50.

Just remember that most "Warbirds" are desigened around a large motor upfront. Putting lite motors with lots of power upfront and servos in the tail mean you will most likely add lead to the plane in the nose so it isn't tailheavy.

My plane is built per the plans except the gear area was re-enforced with CF cloth.

Try the P-47 thread already started here for info on mine and a few other ones that are closer to scale.

I've got that thread memorized. I dislike posting specific questions to those mega-threads. Since the search function here only directs you to the thread, not the post, it can be impossible sometimes to find what you're looking for so for specific questions I just start a new thread.

There are others on RCSCALEBUILDER and RCGROUPS that are very good as well. Definately going to move the gear to the scale location.

I've got 23 flights on my TF GS P-47 which I finished this spring. I got mine down to 18 pounds by lightening up the tail a whole bunch, and using a Moki 2.10. The P-47 really is an easy flying warbird...I love mine!

fit a DA-50, more power, smoother and has rear mounted carb so you do not need to cut the hole, or fit a 90 degreee throat to the G-62

Seriously though this model is way overpowered with the G-62, DA-50 size engines. Friend of mine flies a 1/4 scale P51 105" wingspan on a G62, I have a 42lb Vailly SeaFury @90" wingpsan so that gives you an idea of the amount of excess power you have with a G62 or a DA-50


FYI I'm fitting a DA-50 to mine.

cheers

Thanks Mate!

Your thread is what got me go'in on the TF GS kit as opposed to the Ziroli (though I bought the plans...). The DA's always been front and center but I figured I'd need the weight of the G62. Do you expect any problems balancing it with the DA?

Peter_OZ

My Feedback: (1)

most likely will require a little nose weight but with placement of battery packs and the heavy ABS/glass reinforced cowl I think it will be minimal. I am being frugal with primer and top coat paint in the tail area but wish I had done a bit of dremeling in the tail [:@]! always wiser in retrospect

Mine will have 4 battery packs, 2 x 1700 6v nicads for RX, 1 x 1400 6v nicad for ignition, 1 x 1100 4.8v for landing and nav lights. So lots of weight I can shove right into the front behind the firewall.

Glad I could inspire you to get into it. I went for the DA mainly because it is so smooth compared to the G62 and as the structure on the TF kits is a little lacking I thought it might help it's longevity.

cheers

You can cut about 1/4 inch off the stock carb isolator and get in in the cowl. There are steel inserts in the newer isolation blocks so you can't cut much more off. Or get the 90 carb bend from Toni Clark to keep the carb totally in the cowling.

neddykelly

IRB75 - Could you please advise contact details for Tony Clark - I am trying to get a carby spacer block for my G62 (the one that rotates the carby to align the throttle and choke arms, and have just been told that there are none in Australia.

Thanks,
Ned
