Shawn's right that flying advanced and unlimited is different.

Up through intermediate there may be one snap and one spin. But in advanced you will have a snap on every maneuver and probably every line.

A plane's ability to snap and hold a line are absolutely essential in the upper classes.

I'm just bumping this up a little bit in hopes of finding out what was the result of moving the stabs.

I think the Troy Built 260 35% has the same stab location. My new 260 flies very well and with my DA getting strong is even better. I have gone as far as mixing in rudder to throttle, and all the other mixes (all just 2%) to fly perfect knife edges...ect.

I would still like to hear any modifications. I guess in the end to each his/her own. Whatever makes you happy

The airplane that I took my measurments from was the PMP Extra 260. Short history lesson here. The PMP 260 has also been refered to as the Von 260 due to it's designer Dave Vonlinswe ( may have spelled that wrong) The production rights were eventually sold to Gene at Troy built. Gene changed the construction some but the outline and surface locations all stayed the same. Tom's 260 is VERY close. The engine thrust line, wing and stab center lines are all within 1/4" of the PMP. The major difference was the stabs were 2 1/4" forward on the Wild HAre thus the reason for moving them back 2". As of this writing the airplane has been fitted with a DA 100, the cowl cut and fitted. Covering has begun and I think it should be test flown towards the end of October.

Interesting. I don't fly competitions but I practice the sequences to improve my flying skills. One of the things I have noticed (have no idea why) is that the 260 design just seems to fly more precisely then the 300s or 330s do. Thats what drove me to buy the Wild Hare 260, the lines seem to be some of the cleanest I have seen & the foam cored wings are better then anything except for possibly the composites. I had never noticed the stab being moved, but then I had never looked either.

You'll be happy with the DA 100! Quit stalling only took 3 days to build my 260....just kidding. Well it only took 3 days but take your time. I suspect you will end up needing the same mixing as I did. 1% right rudder at 50% throttle, 2% right rudder at 60-100% throttle for vertical uplines.

I need to. Normally I won't start a project until every single part is on the bench & I am still waiting on the servo arms & servo tray for the 260. Local hobby shop ordered them for me two weeks ago from SWB & they just haven't come in. I spoke with them yesterday & today I am going to order them myself. 4 5945s on the wings, 2 5925s on the elevators, 2 JR 8611s on the rudder and a Futaba 3050 on the throttle should do the trick don't you think?

The other thing I am waiting on is the graphics from Airgraphix. I ordered a real nice package from him to dress up the plane but he asked me for a couple of measurements that I haven't had time to take yet so I'm sure he hasn't started them yet. You don't happen to have the root rib measurement & wingtip measurement do you? I haven't even unwrapped the plane yet as I have been working on getting my Katana re-built. I repowered it and recovered it, put in all new servos & put a pipe in. I fly that plane at airshows & there seems to be something going on just about every weekend around here right now. I flew one last weekend, got one this weekend & there is another one on Oct. 1 & 2nd. Sometimes I wish I had never gotten involved in these things. Last night I got an email asking me to do demonstration flights for another event at a new clubs fall picnic. I swear. Do one good show & they never let you be!

You will wow them with the 260, I was down on the deck with knife edges

I went with 5945's on the elevators. The 5925's are a good choice too, but I think they are so fast they could strip out because of speed. I managed to strip one out on the rudder. They did give me about 50 flights before one did strip though.

Other than that everything sounds good. A fast throttle servo is best. The plane should balance perfectly with two 8611A's in the tail. They are heavier than the Hitecs and therefore perfect! You will have plenty of rudder authority.

Wing span is 44 and 1/4 inches
Root length is 23 inches
Tip length is 13 inches.

To add to what Shawn has stated, I will do a complete write up on
all mods and different ways we finished the 260. Will have pictures
also. May have to go to RCBlimpproductions.com to see it all, as
I am unable to upload pictures here.

Rockyaged, I assume the "Project Extra" is the Wild Hare? Nice looking plane. I like the classic look. I have a 30% Carden done in the classic scheme, wine stripes on white.

Cstevec, The Project Extra on my web page is my Colombo Anderson 38% Extra. Thanks for the compliment. I got the idea for the color scheme from an episode of American Hotrod. They did up a '65 Mustang in yellow with silver ralley stripes. We will be posting pictures of the Wild HAre 260 as soon as there is something to take pictures of. As of right now we are prepping for covering and researching the graphics as my father wants to make it as close to scale as possible.



Shawn

shawn,
What is the latest news on your wildhare 260 project. I am very interested in seeing how it flies with the stabs 2" back Also I am curious how you are goin to accomplish moving the stabs back while keeping the strength and making it look right.
will you get an opertunity to fly a standard wild hare 260 along with yours to comment on the differences?

Hi Guys...

The Project 260 is mine, and Shawn is helping me with it. We moved the stab location
back by using parrallel measurements and then checking that the incidences were correct.
The second modification, to adhere to a more scale appearance, was to cut the Elevator
Counterweight oieces off and re-glue the to the ends of the horizontal stabs.
I am not one of the faster builders of models, so I ask that you be patient. I want this done
correctly and am not inclined to work faster than I am comfortable with. I have 90% of what
I need to finish the model. The last 10% will be ordered soon.
Currently, there is some finish sanding to be done and then covering. I covered the Rudder
and one Elevator this morning.
As Shawn mentioned ealier, projected maiden flight date will be mid- October.

Gerald.

I will be patient and wait for the pics...I can not draw a visual of how this moves the stabs back. The stabs have two aluminum tubes/sleves..In order to move the stabs back the sleves in the fuse as well as the anti rotation holes would have to be relocated. If this happens and it is moved back by two inches then the stab/elevator/ruder/fin assembly would look more like a cap with the ruder forward of the elevators. I know all about patience. I am planning on this plane now and getting a little stuff at a time, My maiden will be aroung Aug 2006..Best of luck with your project..

Confused and curious------->Dan aka dntmn

Does anyone know if this project 260 was ever flown. I have considered ordering another set of stabs and making a set without the counterbalances. Curious if the modifcation improved IMAC sequence flying.

We did what you are suggesting on the new Extra 300 41%. It's not clear if there is a dramatic difference with/without counterbalances. So far I as an observer have not seen any difference, but it may be that a better pilot can use each style to his advantage.
