For those of you who may have performed these tests, what climb angle did you use and how did you obtain it. I did a test with weighing down the tail and the best that I could get was about 12 1/2 degrees when the tail tie down hit the hangar floor. I am thinking about raising the main gear off of the floor, but was not sure as to what height would work out the best. I did place a call to Van's to see if they had a "standard" of unuseable fuel for the RV10, but the reply that I received was that it was up to the builder to determine that. Thanks for any information to help me get by this step.

After many years of EAA and dreaming about it I've decided to build the RV-10. I'm getting ready to order a number of tools in a couple of weeks and thought that I'd ask if anyone has any good used tools that they've decided they are done with. I know that usually builders keep their tools for a long time, and so I expect to buy what I need, but I thought I'd ask just in case. Email me privately if you have any to offer. Thanks, Matt Overholt matthew.r.overholt@gmail.com ________________________________ Message 3 _____________________________________ Time: 08:15:47 PM PST US From: Robert Jones Subject: Re: RV10-List: Used tools Welcome to the thread. I just got N810RK certified in February. Got the 40 h ours flown off pretty quickly. It was great weather to do it in winter where I I live in Las Vegas. Took our first long trip to Yellowstone, Central Mic higan and Kentucky before flying home just a couple weeks ago. 100 hours of t he aircraft. The last leg was flying from Spanish Peaks, just East of the Ro ckies to Henderson where the aircraft is based. At 16,000=99 at ISA +2 0 I was getting 175 TAS at 11 Gal/hr. They are quite an amazing aircraft. Robert Jones > On Aug 23, 2020, at 7:38 PM, Matt Overholt w rote: > > =EF=BB > Hi, I'm new here and preparing to start my first aircraft build.

The tanks hold about a quart more than that. You can come very close to emptying it if you run it dry. Obviously if was rough you would likely suck some air a lot earlier. I usually leave about 2 gals in the lowest tank and make sure I am landing with at least 10 in the other because I am a real Coward when it comes to fuel reserve. I weighted the tail down to get the nose up about 10 degrees. It was a waste of time. I flowed about 48 gal/hr with my Airflow Performance electric pump as measured just before the FM300 throttle body.

I happen to know that the stock mechanical pump continues to deliver enough fuel for full throttle at 11,500 and over 70 degrees of pitch up. No, I didn't have enough brain cycles to think about turning on the boost pump at that point. (obviously not an intention test, but the engine never hiccuped. As for unusable, I pumped fuel out of one tank at a time when calibrating the tanks, and then pulled the quick drain. Less than 1 qt remained with the airframe at normal, on the ground attitude. I haven't felt a need to put a precise number on it, because when I am down to 5 gal per tank, I am landing at nearest suitable runway, period.
