Rich, I would like to hear opinion from you, about carbon tube, when you will recieve it.

6-mins made a suggestions to rcgroups two days ago:
http://www.rcgroups.com/forums/showp...81&postcount=1

6-mins, I tryed to be polite, and helpfull, but now you disappointed me.

Do you really think, as you said:
Suggestion - the GUPPY threads should be removed
they are taking up space are not any use.


I can tell you that many hundreds Guppies were build all over the world, and Guppy threads are visited by enormus numbers of visitors. Just look at the Rating and Views.

Guppy is my original product, I spend a lot of my spare time, preparing the prototypes, making plans, drawings and instructions, spend a lot of time beeing on-line on the forum, and give my best to help builders on best possible way I can.

I did not recieve any money for my work, but I get many friends all over the world and that is a treasure, that anyone can steal from me. Thaks to Guppy, that cute small wooden glider!

So, one ofended "would be a Guppy builder" as you, can not change that, even starting a "Guppy thread removal suggestion" every day to rcgroups moderators.

I decided to report 6-mins suggestion about removing Guppy electric saiplane threads, as I dont agree with it.

Quote:
Hi!

Forum member 6-mins build a Guppy model, and complain a lot about it.
Me and other members tried to help him with helpfull suggestions and hints, but he did not accept them, and build a modified version of Guppy. He made a real mess and dissaster from well designed model... allmost a parody to Guppy proper assembly.

After that, he started this thread, where he suggest, that Guppy threads should be removed.

If you look at both Guppy threads ,
Part 1: http://www.rcgroups.com/forums/showthread.php?t=539755
Part 2: http://www.rcgroups.com/forums/showthread.php?t=846438

Just brief look at the numbers (views), rating and number of happy builders (over 200 all over the world), tells that this Guppy sailplane building thread give so much pleasure to the wide RC modelling comunity, that should not be deleted on base of such maliciousness suggestions, as 6-mins did here.

With best regards!

Hi Mitja,

All the credits are for you. The plan is very clear. And for what's not you have a drawn partlist of al the parts with all the measures. You can printout everything and copy it 1 to 1 to your balsa / ply sheets. You nearly can't do anything wrong. Just look well and work precise!

So I realy don't why all this crumble of 6-mins.

The question here is -

Will it get high enough off the ground to have a crash to withstand?

Hi Mitja, I wanted to take a few seconds and tell you thank you very much for bringing the Guppy to the world. There is nothing or no one that can take away your accomplishments from you. There is always someone out there that will put down anything and everything that they did not do them selves.
Long live the "Guppy",,,, oh and when will the Guppy have bigger Guppies?

Have a nice day....


Best Regards,

Hi Mitja and all,

I have a Guppy since a little more than one month and an Ultron (a 3D depron plane also designed by Mitja) since a couple of weeks and I really enjoy flying these models. The quality of the plans and of the instructions manual are better than what we can found in many commercial kits and the flying characteristics are very very good. In addition, people usually make some compliments about the look of these models. Then, I do not understand the messages of 6-mins.

I hope that 6-mins do not fly in real plane constructed by him...

Hi Mitja,
The tubes arrived- the smaller size is 6mm o/d, 1mm wall thickness. It is well made and seems adequately strong given the thin walls. It is more flexible than some thicker walled tube I have but I think it will be strong enough for the 1.5m Guppy with its balsa boom fairing.

The larger size is 11mm o/d with 1mm wall thickness. It has a layer of spiral-wound carbon and is reasonably stiff, again taking the thin walls into consideration. I really don't know if it's strong enough for a 2m or larger model but if I get around to building a larger Guppy I'll use it and let you know how it goes.

Nice!

If you can use it, there is an explanation of one simple way to make canopies:

the easyest way to make a canopy is to look for the perfect soda bottle, the dr pepper long neck 20oz is perfect for a guppy if you choose the proper area to cut. no boiling ect.

SoCal Guppy

Here is my addition to the school of Guppies. It is a pseudo-hotliner I built it from a Polecat Aero kit. I removed the polyhedral from the wing and added ailerons, but left the airfoil alone. The powerplant is a KD A20-22L brushless motor, Turnigy Plush 25A speed controller, ZippyK 1800 mah 3S LiPo battery, and a Graupner CAM 9-6 folding prop. It is my first electric sailplane and I probably went a little overboard on the powerplant. It ended up nose heavy. I had to add 0.9 oz of lead to the tail to balance the plane and the all up weight came out a little higher than I expected (21 oz). I hope to maiden it today and bring it home in one piece!

Mitja, I have not been able to start my Guppy yet because of other projects.

However, I think it is the most beautiful wooden sailplane I have ever seen. You are an invaluble asset to R/C Groups, and modelers everywhere. I cannot wait for V2, and the bigger Guppy, they will share space in my fleet as soon as I am able to make it so.

Please do not let one Troll dissuade you in anyway, like you said, look at all the posts and views, people are reading with much interest.

Ive built three guppies so far. A person at my field liked the last one so much they paid me $400 for it. The wing goes togeather fast. i would suggest the following:

A strap of CF tow along the bottom of the spar tip to tip.

some 1/64 ply on the sides in the wing saddle area.

use a real CF arrow shaft for strength, and use plenty of poly glue along its entire length.(mitja wasnt kidding here)

Build the tail exactly to plans. you do NOT need large excursions on the control surfaces!

I cover the fuse with 3/4 oz glass, and double the glass in the front,wing saddle forward.
