Well, I'm thinking my P-51 is on backorder, as are my retracts. Not cool. Anybody know where I can get the ARF or Robarts right now for a competitive price? I did, however, get my FTL45 from Hong Kong and as far as I can tell it is one fine engine. It seems very powerful but I'm new to this gas stuff and need to get a tach. I've read most of this thread but couldn't find the dimensions of the cowl. I'm really interested in how wide it is to get a better idea of how much the carb and muffler are going to stick out. This engine measures about 7 3/4" wide from carb to muffler.

Looks like Chief Aircraft may have both the P-51 ARF and Robart retracts in stock. I bought my Robart retracts from them. Here's the link-->http://www.chiefaircraft.com/rcmsec/Models/PowerAirplanes/TopFlite/TFP-51DMustangARF.html

HI...
received my ZDZ 40 RE today ...
Anyone familiar what kind of size stand off I need for this engine ?
Also, is a 1100 mah 4.8 battery good enough for flying few times on a Sunday morning ?
It's first time for me with separate ignition module. Iam used to the good old Zenoah. Any advice about this particular installation ?
Thanks in advance ...

I myself would not use such a small battery if using only one. A 2100 would be great. I dont know about the stand off's since I am using a Revolution. Where do you guys fly in North Ridgeville, I often go back to see family in Ridgeville and never new of a local flying field.

Hi...
thanks for the reply ...
I think I made a mistake ....the battery that I have is 1700 mah 4.8v instead of 1100. Is it still not enough? How much an ignition module draws from a battery pack ?
Here in N.Ridgeville, when it gets warm enough....maybe in August...I fly at this club that is just few minutes from my house. It's off Grafton Road, if you are familiar....here is their web site

thanks

Thanks for the field info and 1700 would be good for the ignition.

Don't waste any money. Fly the airplane with the battery you have and find out first hand how long it will last. Unless you intend on flying all day long you should have no problem with the 1700mah battery you have but still give it a try and find out for yourself how long it will last.

I thought Chief might have them but I talked to them today and they are out as well. I called so many different hobby shops today and couldn't find a single one who has this thing in stock! I even bought one on eBay thinking they surely had it in stock, only to call them (RCSuperstore) afterwards and find out they didn't. If anyone knows where I can buy this plane please do not hesitate to let me know. I'm getting desperate.

I think the ignition battery topic has been pretty well-covered, but the owner of CH Ignition told me that you should get a good 4-5 hours out of a 4.8V 2000mAh battery, so 1700mAh should be just fine.

Alright, for the veterans out there, what would you say are the biggest adjustments that need to be made for someone moving from .40-sized planes to Giant Scale?

I'm still curious as to the muffler mounting dimensions on the various engines out there if anyone feels so inclined to measure.

stewtheman- I have the top flite 1/5 scale arf mustang new in the box. i don't plan to assemble it right away, so if you are interested in it I would sell it to you for what I paid for it, which is about $460 (includes taxes from my LHS). I opened the box enough to glance at it and I looked through the manual and marked some pages here and there, but as far is I can tell it is complete.

I live in Lexington, ohio near mansfield. If you are willing to drive to someplace near here to meet or to my house maybe this would work out - I could order one and get it later to replace this one.

as far as the difference between this and a 40 size- it will take more room to take off- depending on the engine and your skills with the rudder on takeoff maybe twice as much runway. as for flying it will also take up a lot more sky when flying, pretty much in proportion to the size difference.- but maybe only twice as much room not 4 times as much room as a 40 size
landing will take more planning - again you will need more airspace and if you are not used to flaps this means that landing will take a lot more runway than a 40 size plane. however with a pilot experienced in using flaps and flying warbirds you can land them in a fairly short runway. I STRONGLY advise finding someone with large scale WARBIRD experience to help you fly it at first. someone with experience only with aerobats could perhaps fly it but the wing loading is much less with most aerobats these days and they slow down much slower for landing without using flaps. of course this all depends on the final wing loading your plane has and how well the factory assembled (true to the design) this particular arf. when I assemble the arf you need to pay close attention to alignment of the wings and tail surfaces, as well as the cg. crosswind landings in 15mph or higher winds will take good rudder skills as well.

I don't mean to scare you off or offend you in saying the above but only want to give some things to consider, as you asked about this.

by the way- I bought this 1/5 mustang arf because I was going to convert it to electric power but I think I will wait until the A123 batteries are more readilty available (read that as cheaper too

). so i figure this will be another year so I have time to wait.

i do have the Top Flite 1/5 mustang kit almost built- its ready for final shaping and sanding - as a slow builder it has taken me years to build to this point, so you can see that I am not in a big hurry here

.

i edited the price because i found my receipt and realized that the taxes were higher than I remembered.

The biggest problem will probably be your rudder skills. At my field use of the rudder is a lost art. Flying a model to the ground is another area where most people are lacking. Guys where I fly mostly just cut the throttle and glide their planes in. That won't do at all for this Mustang. I hope neither of these situations apply to you but if so get help.

Stew....
I think there are some benefits and some disadvantages in flying giant scale.
Since I don't know all of them, the few that come to mind are:
for the benefits you have a larger plane to fly which it's easy to see in the sky, better "feel" for the plane in any wind condition, the gas engine is more reliable than glow, therefore almost eliminating dead stick landings ....and overall bragging rights at the field

for the disadvantages you have the same big plane to fly, and it's imperative the use of a good computer radio with expo and dual rates, use of the rudder for coorditnated turns, need to fly the plane from take off to landing, expecially on landing where straching the flare can result in tip stalls and crashes, few more things can go wrong compared to a .40 size ( retract failure, ignition failure, ignition module interference, more battery packs to mantain and charge and fail) not to mention the right vehicle to get your plane to and from your field, and lastly the disgusting feel you have after you crashed your $1500-$2000 investiment.

I have been flying large scale for several years, and I LOVE it.
I some time help few friends take their .40 or .60 size plane in the air, and it really feel like a toy in the sky , compared to the large scale ones.
I strongly recommend for you to get into giant scale, it's more rewarding to fly a plane that acctually need to be flown, that fly a "kite" with an engine in the front.

Hope this help a little..

Thanks for all the advice! I've been focusing on finishing my 73" CMP P-40 lately, since the P-51 and retracts are both on backorder. And now that I finished it of course the last two days were the windiest I can remember in a while! Ed, thanks for the offer but I think I'm just going to wait this one out a little longer. It just took a few days for me realize that I didn't need this plane like I thought I did. The weather will probably be a lot more cooperative later on as well so it'll work.

Anyhow, I noticed that a couple of you mentioned the need for rudder skills with the giant scale planes. Is there really that big of a difference in the way they fly? I have been flying the Hangar 9 P-51 PTS (.45 engine) for a few years now (I never flew it with all the training crap on it but simply bought it because it was the best value and easiest to get up and flying) and am completely comfortable with aggressively flying and landing it. However, I do not use any rudder while in the air (or very rarely). I am self-taught and have always preferred to turn with aileron input then elevator. Is this how most people turn or am I on my own on this one?

I guess the rudder comments really surprised me because I have a little 34" foam GWS P-51 that I also like to fly but it's about three times harder to fly than my .45 P-51. There is a much smaller acceptable margin of error. So I just assumed that a giant scale P-51 would be even easier to fly than my .45-sized one, aside from the obvious need for a larger flying and landing area. So, I guess I'm wondering how you guys would compare the flight performance of a giant scale P-51 to that of a smaller scale P-51.

Flying the giant P-51 is very different. Read this colum for some good info.
