Worldmodels Ultimate 40S - 7/18/2005 5:38:43 PM

Status: offline 		Hi, everyone;
I just got me an Ultimate 40S from Worldmodels. A buddy of mine flies one with a Saito 56. Flies great but could use a bit more power in vertical. So I decided to put my Saito 72 in it. At the LHS I was told I should have unlimited vertical with that engine. W'll see. Anybody here with the same palne? One thing I don't like too much: Only one servo for four ailerons. On the other hand, the ailerons are small. Overall quality is good, built very beefy, not necessarily the lightest plane in its class. Any input is appreciated!

Thottle management is a MUST! It doesn't like to pull a loop because engine torque rolls the plane hard left if you give it any throttle at all and low rate aileron is not enough to correct it. I did a snap roll with it and the hs-81 broke a gear but I was able to get it down ok. Metal Gear servos would be highly recommended if using the 81s or similar.

Status: offline 		sounds like a good flyin plane Im ordering one tommorow, going to put an 0.S 46 AX, If thats not enough power I will probably put a saito 91 in it the 46 should be enough.

Status: offline 		Hey, planetwister;
A Saito 91 is way too much power and weight up front for this plane. The max. engine size is a Saito 72, believe me. Don't go overboard with redundant motor power. The 72 gives you unlimited vertical.

Status: offline 		I'm new to this addiction. I Have an almost done 40S w/saito 72. From all reviews read, this plane should be excellent to fly. I have found 2 reviews that point out CG differences compared to the manuals 3.74. One review states 3 inches from upper wing tip, another says 3.2. I also have a shuttle 30/50 evolution-37 OS-GY401/S9254,JR770PCM. T-REX-XL w/many upgrades.

The planes just looks awesome with True turn polished spinner.

Status: offline 		I had (yes had) an ultimate 40s that had a Saito 72. It flew well under power. It was on the heavy side at 5 pounds, 7 ounces dry. The heavies was due to my over use of epoxy. Be very sure of how much time the included ~9 ounce fuel tank will provide with a larger engine. Also be sure to keep the plane as light as possible to help out your glide in a dead stick landing.
