I want to use a gas engine instead of a glow engine for this size airplane. Any suggestions? [&:]

Are you talking about the 60sized or the giant scale. I think the best engine for the 60 sized top flites is the super tiger G90. If you want gas you should go for the giant scale p47.

jeffk464,

I would have liked to use a 90 in my TF 60 sized Gold Edition P47 but I wanted to have it fully cowled for scale realism. I went with the ST75 because you could get the in-cowl header and muffler and it has been stated over and over again that the ST90 would over-heat with the in-cowl header and muffler. The instructions even show the ST75 so that's how I went. Seems like it will
have more than enough power.

Cheers,
Andy

The planes is the 60 size. I haven't started on it yet. I have been thinking about selling it and purchasing the Giant.

looks like nobody wants to answer the question so I happen to have a answer for you for a 60 size you can run the Zenoah G-20, or in my case a BCMA 26spe engine in my TF 60 size P-47 T-Bolt I am building ,Brillelli engines have some smaller gas offerings there are lots of small gas engines for 60 size panes you do not need to get a giant scale for gas.
what you do have to do is have throttle management mostly because these engines are a little much for these planes I kind of like a little extra power myself check out the review of the Hangar9 hellcat on RCU the guy put a Z G-20 in that one seems fine to me, here are some photos for you of my progress on my TF 60 size P-47 great model to build been at it for just a little while now.
the weight is about the same as a 120fs for the BCMA check www.bcmaengines.com they run well.

Hey, thanks for the info. I did see one of your forums awhile ago, but I lost it. I actually did look into the that engine yesterday, and that may be my pick. Can you believe when I contact TF about using a gas engine, they were totally against it. I wanted to stay away from nitro. Nitro costs more, messy, and the four stroke nitro are way too much money. So did you finish your p47, and what type of covering are you using?

How about an RCV 120SP? This would allow you to fly with a large, close to scale 4 blade prop and have everything inside the cowl.

for progress on my P-47 build check with TF P-47 balancing act in the warbirds section I will be posting my progess there and the instalation of my gas engine as well as flight info

rcv engines are nice, but I want to stay away from glow fuel.[:'(]

I used a Magnum .91 four stroke in mine. Is fairly economical, hauls it nice, and does all scale manuevers very well and quickly became one of my favorites. Engine is fully enclosed except about half the muffler sticks out the cowl on an angle.

If money is no object you can always go electric, no mess, no vibration, no hearing damage, and less chance of chopping off any digits.

I've been considering changing out my Saito FA-100 for the BCME-26 on my P-47 as well. I just wonder how big of a 4-blade prop the BCME will turn.

I would think fairly large 4 blade, the posted max size is 18/10 for the little bugger, I am planning on going with a 15 or16 3blade expect rpm's at about 8,000 I would think a 15 or 16 would be awesome wouldn't mind a 4 blade myself they look so cool and scale.
from what I have read, I have no expeirence with 4 blade props, for every blade that you add, you drop 1" in dia. Y or N.

That sound pretty cool having a 4-blade prop on that plane. One site recomends a 15x8 or16x8 for a four prop.

I looked at the blueprints on the P47. I feel uneasy having only one servo for the ailerons. I always install two, even on my past trainer. How are you guys setting up on your p47.

I've been thinking about this plane also and have a G26 with electronic ignition. How would that work in this plane? From the pictures, it looks like it would fit.

I wouldn't know. I would check dimensions compared to bigtim's bcma engine. Looking at bigtim's pics the bcma engine fits well in the cowl

I am going with 2 servos for the ailerons and 2 for the flaps for the security, I am thinking I want max control for this over powered bird.
I am not sure about the zenoah I have not actually seen one in person , the BCMA also has E.I. and is pretty light for a gas engine I am using a rear dump muffler to keep things in the cowl and the scale look the only major hole I am planning is for the side draft carb.
