Status: offline 		It looks like H9 really listened to us about the P-51's shortfalls. Over 80" and the retracts and struts look they will work 250% better. I wonder if they beefed up the gear rails (another huge weakness on the 150 'Stang).

I also hope that the manual is better. All the obvious steps were provided in the Mustang manual, but there were a bunch of critical "tips" that could only be found here on RCU.

Status: offline 		I am concerned by the retract rails shown in the manual. They look to be two layers of Lt ply, While it will handle most of our landings it will never stand the test of time. I have a Magnum 41 (now know as the USA 2.5) that would fly it nicely. But I have decided that I must be more diceplined in my ARF buying. I'm Tired of spending 20-30hr putting the thing togeather, then spending another 10-20hr retightening covering and fixing things that don't work as intended/expected. After the second year It usually needs to be recovered to the tune of another 10-20hr.

Compaired to a model I build intending to use as a fun scale/practice model meaning plastic covering and CRS struts takes from 40-80hr (flop tite small to flop tite big model). By the time I buy the retracts (I want), wheels (I want), fuel tank and covering the cost is about the same. Added bonuses are that I can build all the lanning gear covers and hatches out of fiberglass, the landing gear front rail will be made of maple and be glued to ply doublers.

I'm sorry I had to do this to keep from pulling my visa card out of my wallet.

That remains to be seen, they look plenty of sturdy to me, and since no one has actually seen them its all speculation but I can say that I had the WM 80in mustang and have flown the stock retracts for about 2 and a half seasons with no proplems. And these retracts appear to be a hell of a lot better than the world models retracts. But then again some people do tend to land a lot better than others.

Status: offline 		Terry , I agree , I think from the pics and ad in the recent Fly RC , H9 may there mark on this one , the flaps look good , retracts seem to be designed with good thought , wheels are small but overall the P47 looks like a good bird . Considering the cost , I guess there on the mark , I also do agree that the engine suggestion seems under powred unless the airframe is exceptionally light witch is good and bad . I think there 60 to 90 size birds are great with the exception of the very light designed front ends of the planes .

Status: offline 		Paladin,

I, for one, appreciate your observations. While some may consider it bashing, your concerns about the rails should be posted. After all, that's what these forums are for, discussion about the products.

Status: offline 		Not to beat a dead horse but I have a friend that bought his first warbird three summers ago, A hanger 9 P-51D. I showed him how to add flaps and I taught him the right way to fly warbirds. That ment there where the usual share of super sonic landings until he got the hang of elevator controls speed (pitch), and throttle controls rate of desent. For a total of around 60 flights before the front landing gear mount broke out. It broke out on one of the softest landings, which is typical of light ply.

We had talked about this happening while we were installing the flaps. It was not a matter of if, but when! The problem has nothing to do with the design and everything to do with materials selection. Basically The problem is this, the landing force with a standard LG mounting system puts the front mount in a tensile load and the aft mount in a compression load, all materials are 3x stronger in compression than in tension. This translates into the ply plate by the screws, creating a point of high stress concentration. Over time this stress concentration breaks down the bond between the layers of the ply, that allows more movement in the mounting rail, which speeds up the breakdown of the ply, until final failure. Those of you that have removed ply landing gear mounts can remember back and think about how much ply was still left with the plane. When I build a model I use maple engine mount material in this location (front only).

If you buy a plane with Lt ply landing gear mounts they will last for about 40 flights. The gentler the landings the longer they will last. If you want to respond to this and tell me I’m all wet take the time to write hanger 9 and tell them also. But the question is do you want it RIGHT or adequate! That is what the ARF manufacturers need to know.

Joe

Status: offline 		Paladin, you havnt seen the plane yet and its already inadequate? Simply pull the covering off the area and epoxy or glass the retract bay and go flying. I'm sure who ever designed those retracts (and they look pretty damn good to me, or at least a step in the right direction) thought about beefing up the area they will be mounted to. If they didnt, I will do it myself.

I think all your assumptions and calculations are right.

I would still rather reinforce the landing gear than build the whole f#*king plane.
