Full details ...

The first owner dropped it on the landing and repainted it added weight.
I facilitate EVERYTHING!
The rules limit the weight of 20 kg maximum and 5 liters of fuel, otherwise disqualification.
It looks like I wasted my money ...

Looks like you need to get creative. Fortunatly here in the states we have a little more weight to work with. Still a challenge given the scale potencial of the airframe. Just glad CARF made the basic airframe so light.

When building the system, a 45lb weight target was definately not a consideration. Even the new design using the LADO linial actuators is not that light. If we had time, perhaps a special lighter system could be developed. Maybe using ABS structual parts. I dont have time to figure it out right now.

Not sure on the question. The prop must be adjusted to achieve a 3700 to 3900 maximum ground RPM on the Moki. The pitch will be around 18".

I have used both wooden and CF blades in the Solo hub with no problems.

The CF blades are about $100 each through CARF.
The wooden blades are about $56 each, painted black with yellow tips, through Solo. I use a 30" prop on the 215 and the 32" on the 250. That way the pitch stays aboit the same.

Gary and others, can you tell me what throws on the control surfaces seem to work best if they differ from the manual. Thanks

Our radios are at my brothers house. I will have to check later. I do think we have posted them before here in the thread somewhere. I will say thay the first time long ago we used the tecomemded throws and they worked great. In all but the strongest of winds you will want all the flaps in for the final landing approch. She is sensitive to pitch. Not a lot of elevator is required.

The pitch will be about 18". The prop from Solo will be around $600. DO NOT BUY THE CARF look a like prop. It isnt like the Solo, it just looks like it.

Gary, what does 18" mean. 18" means 18 inches. I'm wondering if you mean 18 dg. Pitch. If so, how do you get that? Make a 18 dg wedge and place it under the mid point of the blade and turn the dial to to it? Thanks,

Good question. Think of our Corsair propeller as an "air screw", (actually called that sometimes). The pitch of a propeller is measured this way; if the propeller was being screwed into something solid, it would move forward 18 inches after one revolution. Hence the pitch is described by that 18", or it is said to have an 18" (pitch).

The dial on a Solo prop does not translate to any particular pitch. It is really just a reference as you move the blades. The most important tool in setting your prop is a good tack. You need to set your prop to the correct RPM on your engine. Not a a certain pitch.

Agree with Gary on this one. Don't worry about the actual Pitch measurement or setting on the prop hub dial. you adjust, tighten up, run the motor and check it with a good tack meter. Keep doing this sequence until you get around 3800 rpm on the tack meter at full throttle. Then you can note the tick mark on the prop hub for future reference if you happen to loosen up the prop hub and want to get it back to the same pitch setting. This is how I setup mine and it works great, many many many flights on mine with no issues following this method of adjusting the prop pitch to the correct full throttle RPM

Cheers

Has achieved weight of 16 kg .......
I sacrificed the mechanism of lifting the wing ....
And to the limit made it easy all that the first owner did ....

And found another 4 kg ...... : (
A total of 20 kg flight weight without fuel, the engine's thrust 24 kg
Everything on the brink of a foul.

Default Big Hog

I noticed that there are white stripes on the outboard wings of Big Hog that are not present on other birds of the squadron. What are they and were they painted on ?
Thanks-Mike O.
