Hi all, I've aquired my second Knight 3d, the first I've sold a while back.

Anyway. Upon stripping/assembling the Knight, I've not noted a few things, that I'd like to have other Knight 3d owner's comment on:

1- The manual is absolutely crap. I honestly can't see a novice beiing able to maintain his heli with that....

2- What type of head damper options are available out there? My Knight has a plastic tube with one o-ring on. The manual is vrey unclear about this part.

In general, I love the Knight.

Greetings

"1- The manual is absolutely crap. I honestly can't see a novice beiing able to maintain his heli with that...."

The manuals are getting much better as new models are brought out. Compass is contstantly improving both the instructions and the packaging.

Although the older manuals lack some detail, I had no trouble assembling or setting up my Knight 3D (1st generation machine). I agree, it would have been pretty challenging for a novice (although a novice would probably not be in the market for a very hot 3D machine).

Is there something specific that you had a question about?

"2- What type of head damper options are available out there? My Knight has a plastic tube with one o-ring on. The manual is very unclear about this part."

There are KBDD Dampers available if your Knight 3D has the 8mm feathering shaft (the older ones have 6mm feathering shafts).

The Knight 3D has had three different dampers, that I am aware of:

The first generation dampers were, if memory serves, were made of red, hard rubber tubing (same as for the older Knight Pro). The next generation were similar, but made of a clear tubing and much harder. The last generation were the plastic (actually delrin) with O-Rings. I believe the third version was included with the newer machines with the 8mm feathering shaft.

"In general, I love the Knight."

Your last statement only confirms that you are an extremely intelligent individual with discerning taste.

I am planning in running a YS56 motor in the Knight.

Would there be any issues with the high preasure in the tank?

I see the tank has two "indents" either side.
On my Vibe 90/Hirobo Freya, these indents are used for tank supports that obviously have an effect on a preasurised tank in supporting the sides.
Is there brackets that I don't have?
The manual/parts lists shows nothing.

as already said,the only aftermarket options I am aware of are the KBDD dampers.they do come with spacers in the kit so other dampers may fit,but I am not 100% sure on that.

the stock damper set up gives you the option to run 3 ways.2 o-rings,1 o-ring inside or 1 o-ring outside

the TT53 in my K50 pressurizes the tank(muffler pressure) and there seems to be no issues with this

The fuel tank is common between the Knight 3D and the older Knight Pro. The "indents" are for small rubber parts that hold the fuel tank in the Knight Pro. They are not used on the Knight 3D.

As far as the YS engine goes, the crankcase pressure is far greater than normal muffler pressure. I have not run a YS on a Knight (truthfully, I have not had the pleasure of running a YS on any helicopter in about 25 years). I have, on other machines, seen people put strapping tape around the tank to keep it from expanding too much. I do not think this necessary on the Knight 3D because of the way the tank is mounted.

Hopefully someone who runs YS will comment on this.

I run the YS56 on K3D and the tank does bulge out a bit.

Have not seen any pressure problems though, only that the tank supports on the bottom seem to be wearing into the tank as the heli vibrates.

Seen white dust around the edge of the tank supports.

Been meaning to put some rubber edging or sand the sharp plastic on the tank supports.

I have some of the latest PDFs of the manuals and parts list, as well as some pro manuals for aluminum bling numbers.

I run the 8mm 2 piece head with the nylon and 2 o-ring dampeners. They seem sloppy on the bench but fly great. They do wear out quickly, but o-rings are cheap.

The exploded views are all you need.

Overall, flies sweet as it is!

Cheers.

Thanks for all the feedback people.

True, the exploded views are great.

I'm going to go the YS56 route, and see how things go from there....

If the tank needs slight modifications, I'm sure it can be done.

With this product:

http://www.rcheliworkz.com/product.asp?specific=116455

you can use trex-600 dampeners. You need the 8mm spindle for this to work though.

I got a fever! The only prescription is MORE 6HV
