|
Rick,
i would be interested in the Grove gear for 2 reasons. I installed my gear per the picture in the instructions which was wrong and it put my CG to far aft at low fuel and heavy load. i would like to get the lighter gear and move the CG in relation to the wheels so i could rotate sooner and hold the nose off on landing. picking up 15 lbs would be secondary.
do you know what is involved in changing out the gear and what parts will be needed & $$. is it a simple swap out?
is the bolt holes for the axles pre drilled.
thanks
bobby

Rick--- isn't your explanation backwards (opposite) from what you want to accomplish?

Hi Rick,
I bought the Grove gear for my XL. The gear comes drilled with wheel mounting holes. I also got it gun drilled for the brake lines.
In order for the gear to fit, you will need to buy or build lower adapters to mount the gear in the standard Zenith upper gear channel hardware. You can buy the adapters from Zenair Ltd in Canada. The price I paid with shipping, etc was $185. Pricey but done right. The price will vary with the current exchange rate. You mount it toward the front to move the balance point forward, thus making the plane a little more tail heavy on loading and rotation.
The gear needs to be notched just like the Zenith gear. Keep in mind that this gear is not 6061 but a 707x alloy that is much more susceptible to corrosion. Therefore, you should plan to at least prime it as soon as you get it for protection.
I can say from the experience of a forced landing in another XL with standard gear a few weeks ago that if I was able to keep the nose up a little longer, the nose gear would not have folded under the the plane and I would have sustained no damage. Of course, the last statement is based on the assumption that the Grove gear adapters are strong enough to prevent the rotation of the main gear within the clamps under that type of force. Nothing is for sure until you test it to its limits.
Hope that helps.
