Posted: Wed Jun 01, 2011 4:21 am Post subject: 7A maingear legs on 6A |
|
|
Noticing that the 6A sits pointed kinda nose-high.....also, mine seems to try to take off before it is really ready. Maybe because I'm putting backpressure on the stick to keep weight off the nose. I operate mainly from grass strips and have already made a couple of changes to enhance the take-off/landing safety – namely larger tires all around and upgraded brake calipers/rotors. I already have the nose gear leg mod for the shortened thread – and newer style front fork to fit the larger nose wheel.
The 7A sits straighter - I'm thinking because it has longer main gear legs. Will the 7A main gear legs fit in the 6A mounts? Any reason not to change over if they do fit? My reasoning here would be less backpressure to lighten the nose and it wouldn't be rotated enough to try to fly early.

Here’s what Van’s responded with:
It won't work - the 7A gear legs are larger diameter and won't fit. Try trimming more nose down prior to takeoff so the force to pull the nose up is higher, that will give a better feel than if it is neutral with little force required.

I do just the opposite; as soon as I can after full power I lift the
nose wheel off and just let the plane fly off when it is ready.

I've no experience taking off RVs (yet!), but the traditional method for a soft-field takeoff with a tricycle-gear aircraft is to hold the nose off the ground (stick full back as you start your roll, gradually releasing as you pick up speed), then as soon as the plane lifts off hold it in ground effect until you've reached at least Vx (won't take long in an RV!). As for trim setting, it seems the safest would be a setting that gets the airplane in a climb (perhaps at Vy or faster), so that if you get distracted right after take-off and relax the control for some reason, the plane will continue to climb up at a nice rate rather than pitch back down towards the ground.

I found the -7A mains are too tall for me. Same for the -9A. I prefer the
stance of my -6A. I've not found it to be a problem, after hundreds of
take-offs and landings since its maiden flight in 1999. I'm still using the
original gear set, to include the original nose gear fork that some have
bent back under the firewall and prompted "mandatory" service bulletins. I
start my take-off rolls with the elevator trim at neutral. If I've done a
good landing, the trim is in the neutral position at the end of the flight.
On the take-off roll, I apply just a little back pressure on the stick and
not force it off. The nose will come up, when it's ready. As soon as it
breaks ground, I spin in a little down trim to stabilize the climb. I use
the same technique on hard surface and grass.
I hope this gets to the RV-list. It's been years since I've responded.

Ralph, I had exactly the same situation with my Rv-6A with the tail squat. Then I had a rather hard landing that bent one of the gears (actually both), when I got my replacement gears from Harmon Lang
http://www.langair.com/
and installed them, I found my RV-6A set a bit higher overall and the tail was now considerably higher than previous. When I park next to other Rv-6As the difference is quite noticeable. I called Lang and asked if the new gear were longer than the old gear and he stated the dimensions were the same. Well, perhaps they are but they are either using a stronger alloy or my Rv-6A has lost considerable weight {:>)
