Default Graupner Showflyer...anyone ?

Have not started to build mine yet, but it is next in line

Since Hobby Lobby is out of stock right now, there must be others out there building or already flying this plane, and I would like to hear more about it, as well as recommendations while building and maiden flight.

Anyone ?

Wait till next week as I just finished reviewing the plane. It will be in the next issue of RCU Magazine coming out next week.

Trust me you will love this plane!

Has anyone installed a steerable tail wheel on a showflyer, Do you even need one? When you ordered your kit did it make it to your door without any damage? What are some of your personal CG set ups.

I have a small steerable tail wheel on mine. I think whether you go with it depends on how much taxiing you intend to do, and how precisely you need to taxi.
it made it to my house ok but was pact very poorly. I am amazed there was no damage. if you want all out 3d you are going to need to balance this plane very near or at it's max rear limits. if you are after all-out 3d performance, disregard the CG recommendations of the guy who did the review in the rc universe review. if you use screws to hold the canopy, reinforce the holes or the canopy will begin to crack from vibration.

Hello Outsider,

Thanks for the advice. I have heard that the canopy's do crack due to vibration. Do you have any personal CG set ups that you liked? The book calls for 135mm to 150mm. The guy that did the review said that he set his up to the farthest rearward CG, and then after the test flight he put it forward 1/2'' of that.

The wing had a cracked rib right out of the box and I sent it back for a replacement. The new one was perfect.

Thanks.

I don't know what you intend to do with this plane or what you are used to!! so it's hard to advise as to the cg that will work well for you! I just read the "flight report" part of the review and he says it balanced in the "range"! i don't see where he said it was at the rear most cg allowed.

this plane is going to be elevator sensitive no matter where you balance it. use some expo on low rates and a lot of expo on 3d rates...this will help. This plane should hover well even if it's balanced in the nose heavier range. it should also do inverted flat-spins with the nose heavy....but it won't do an upright flat-spin unless you are sitting on the rear-most cg.

another problem with this plane is orientation of the wing !! both sides of the wing are the same color scheme...i changed the bottom to make it easier to see.

Thanks for the advice,

I really think it needs a tail wheel. I had no control on the taxi way. Everyone said that I wouldn't need it, but I think it really needs one.

I did ended up using one on mine. You will not have much control on a paved runway. Specially not when the wind is blowing.
I would cut the wingtips off too. Increases the roll rate and helps to lock into the Knife Edge better. Didn't do it on mine, but would have if I wouldn't have sold it.

Is it just me, or is this ARF just a wee bit overpriced? I like the plane... but, Wow.

it's German not chinese...that's why it's expensive.
it is very well done however!

Torrey.....I didn't realize it was you !! If I would have know, I would have told you that you would need a tail wheel.....lots of taxing required at sepulveda basin [:-]....the wind will make precise taxing without a steerable tail wheel impossible.... I'll be looking for you and your showflyer at the field...[&:]

Have you seen one without the wing tips on it? I noticed there is a lot of roll coupling. It really doesn't want to stay in knife edge. You have to fight it all the way. Rolling circles are not as easy because using the rudder just makes matters worse in this maneuver. Don't get me wrong, it can be done, but my 40 trainer does it better.
