i Have a p47 with aproximately 6 foot wing span i will send pictures later but any idea how big of an engine do you think i will need

thanks dave trimmer

Dave,

If you are a beginner, please don't put any engine in the Jug yet. You will need at least to have mastered a high wing trainer, and have a couple of sport models under your belt before flying that Heavy Metal 47. Trust me, and I'm not trying to rain on your parade by saying that. It is NOT a model for a low time R/C pilot. I think that your 47 will probably need something like the G-38 gas engine, or even the ZDZ 40 Gasser to fly correctly. But if you are not an accomplished R/C pilot, please think about a different model for starting out.

how much does it weigh?i had the topflight p47 and had a sato 120 in that one.it weighed in at about 9 pounds or so.most 60 size airplanes can use from 60 to 90 2 cycles.when you use a 4 cycle engine you can go with slightly bigger up to a point.hope this helps.

first off i have earned my wings about 10 months ago, secondly i don't have a weight, servos and the tank yet haven't been installed. i'm hoping to put in a 1.00 to 1.20 glow engine in it from the weak signals event in ohio on april 13th .

Edit: it will definatley be a four stroke

Do you have any idea who made the kit/ARF?

G'day Dave,
If you are not a beginner, then post this in Q&A or Glow engines, whatever.
It is confusing for us, to see a post like this, in the beginners section.

Thanks Dave.

The post may have lacked some details but confusing? Nah! This is actually one of the easier ones once we get some more info. He's still enouigh of a beginner that he doesn't realize what info we need to help him properly.

It is good to see that Alan has been appointed moderator and can tell people where to post.

no i dont ive been searching but can't find a thing.[:@]

You shouldn’t attempt to decide on an engine until you have some idea of the weight and the wing area. You wouldn’t decide on the engine for a dump truck until you knew the loads you would be carrying.

I agree with the above comments. Thats a fair size wing so you will be needing at least a 60 but more likely a 90 size to fly it well. However there are many variations of kits for the P47 and from that size it could weigh 9 lbs. or 15-20 lbs. If its around 9 lbs. a 90 size will probably work ok. If its more like 15-20 lbs. you will definetly want to be looking at gassers. Maybe someone from an RC club could get a look at the plane and have an idea of what you will need.[8D]

I dont have any comments on your question, but I noticed we have the same last name. Ive never met another trimmer Im not related too.

if you post some pics in the warbird thread you started then you will certainly get a ID from sombody who knows the model, then you can get a instruction booklet and have the recomended engine for the plane.
unless you have the specs. its just a guessing game you need to be more specific there are alot of airframes out there that require specific size engines to get you in the air a 72" wing is pretty large and you may need something larger than a 120fs.
Top Flight recomends a 120fs for there 60 size P-47 in the top end of the engine range you might need something in the 180 size to get it flying or even a small gas engine.

hey same here.

Ok i have some pics, but i cact get them with the plane in one piece do to snow. so here they are...

Definitely kit built or from plans. That narrows the search somewhat.

Top Flite makes 2 fine kits. A 63" @9 lbs and a 85" @21 lbs. Don't match yours (@72") but you may just want to compare specs.

that is a Top flight 60 size P-47 I am building one now, the recomended engine range for a 4st is 90-120 if you want a manual for your records you can down load the specs and all the CG and weight info from here http://www2.towerhobbies.com/cgi-bin...?&I=LXHU86&P=0 a picture is always the most helpful in IDing a plane.
for a first warbird they are a great start you will like it its a real solid flyer

i checked the pic from topflight and noticed some decals were the same and the serial # was the same as well as the desighn of the nose cone. the 6 ft was just a really really rough estimate and turns out mine is also 63", after I find my Tape measure in my bed room.

thanks for the help, it also states that a 1.20 is the top side of the 4 stroke. so i will have no problem for power, Now i just need those drop tanks.

thanks for your help. i totally forgot about topflite.

Thanks again, Dave Trimmer

Big Tim spotted the decals. I give him the credit for that. Of course he cheated because he's building one.

I PMed big tim but decided to post anyways, what servos sould i use for this plane.

thanks dave trimmer

just sent you a P.M. about servos but I will answer it here also for the TF 60 size planes any standard size servo will do just fine such as the Futaba 3004 ball bering servo it has plenty of power for this size plane and is not to heavy.
TF planes tend to be a bit on the heavy side there well built and if you compare them to a Hangar 9 there tanks that fly.you don't need any thing more powerful than that for your plane for sure.

Dave, you can download the manual for the plane. There are links for it here
