Hiya All,

This is my first post here, I'm a newbie with about 6 weeks worth of more or less cheerfuly emptying my wallet on helis, and I'm having a lot of fun so far. I started with a CX which is of course still my main bird. I also have ReaFlight's G3.5 sim, and I'm very slowly and very carefully building a T-Rex SE. (I don't have heli experience, but I'm a major tool-user...).

Today, having gotten a bit tired of waiting for dead calm air here on the north coast of Califonia air to fly the CX, and also getting tired of its general mushiness, I bought a CP Pro. This afternoon I got it airborn briefly, and I think I'll do OK with it except for one thing:

The world here is not paved. There's grass and dirt around our old farmouse. There are twigs and leaves and such on the ground. The CPP tail rotor has 3/16" (three teeny-weeny sixteenths of an inch!!!!) of ground clearance! Do the designers of this bird live on sheets of glass? And what's up with that spike masquerading as a tail stand?

The only way I can get airborn without the tail rotor hitting something nearly every time is to pop the heli into the air, which is not comfortable for me yet.

I see three possible solutions (without getting into elaborate projects):

1) Sleeve the bottom of the post with a curved tubular skid, which would kill two birds with one stone (pardon the expression) in raising the tail and keeping that ridiculous pencil-lead from sinking into ant-holes and such. the drawback would be that the heli would be leaning forward. How bad would that be?

2) Fit a smaller diameter prop (or cut the stock one down). Any advice on this?

3) Raise the main landing gear. Is there a bolt-on way to do that or do I have to re-invent the wheel?

Thanks very much for any help and I hope to return the favor further down the road.

Happy Flying,

Oliver

You can cut a piece of fuel tubing and glue it to the tail stand. Or you can cut about 1/4 inch off the prop. I have done both and they work either way.

I just slide a piece of tubing over the bottom of the "post". Serves to raise the tail a bit and also a bit of shock absorbtion. No glue needed if you use the same size tubing as used to hold the skids on, etc. Use a piece 3/4-1" long with about 3/8" slid on the post, adjust to your taste.

superskidz are a bolt on way to raise the main landing gear. They add some weight to your CPP but are much stronger and look cool too. You will have to decied if the extra weight is worth it. The tubing idea seems like it would work well too. If you have some CF rod (ya know broken skid rods. LOL) around you can use the tubing as a coupler (w/ a little CA glue) and add even more clearance.

DD tail will give you more clearance too.

I just take a 4'x4' piece of plywood and throw it on the grass. Instant helicopter pad.

lol, well now that would be much too simple. The box the CPP works well too

:shock:
If you can land your CPP on a CPP box?

WOW!
:noteworthy

Try DVD covers 90 degrees to your superskids in your living room at different orientations. Gotta keep it interesting

:WOW
Maybe when I'm safe enough flying my CPP in the house I'll give that a try. :roll:

At the moment, I'm having to work hard to keep it in a 6ft x 6ft area. :oops:
