Any1 thinks it's better candidate for FPV than easy star?

I'd stick with the Easystar.

My one of these just arrived today ( ) Been looking for an extension on the Tipsy theme for ages now (learnt to fly with a Tipsy)

Quick question however; instructions say use CA to build, but the kit includes a tube of UHU Por.

Can I use it or will it turn into a sticky mess?

Personally I'd stick (pardon the pun) with regular CA.

Love the pun!

I thought as much, but couldn't see any use for the Por in the destructions which made me wonder...

Thanks for the quick reply as well!

The model was initially designed as a styrofoam model - hence the UHU-POR. As it carries the UHU name and colors, there has to be at least some UHU in the kit - and CA is not a good glue to sit on the shelf for long.

I believe that the included POR is only for gluing the pushrods in. As above use regular CA for the rest.

Thanks Gordon, found that eventually!

Got about an hours worth of work to finish the Uhu now, but may as well take my time as the wind is useless today.

Tomorrow looks OK wind wise for a maiden flight? Would recommend stock elevator throw and a bit more than stock throw on the rudder....unless you are a complete beginner, then go for stock all round. Please make sure that the C of G is within stock limits as it gets lively if you are a bit too aft.....

Have fun

Wind looks great for tomorrow, and I'm working all day - well until it gets dark anyway

I've been playing with different packs and the C of G. I'm going to have to be careful with this I think. My heavier pack is around 90g (1250 mah 2S1P) and just seems to get a reasonable c of g. Seems quite a tail heavy plane.

But I'm not getting anywhere near the 650g AUW, more like 400-450g (unless I was reading the scales in a bizarre way. ) so I'm thinking a touch of nose weight is possible (or even a larger pack).

Saying that if I could squeeze a 2500mah pack in that'd keep me up all day. Best maiden first though!

I use a 2s1p 1500 pack and have to add a small amount of ballast (or my Alti2 logger) to get the C of G sensible. IIRC my UHU weighs 475gms rtf.
My typical flight time without thermals is about 40mins :-)

Well, forecast isn't as great for this Sunday as last, but I'm free and my own man for the day. Rain or shine I don't think I can wait any longer - I've even put all the stickers on, something I never do before I fly a model for the first time!

Just need to balance her out. Ballast in the front is going to be required.

Still debating whether to put the central u/c wheel in or not. I fly from thick grass so although it's going to look good I'm a little worried it will cause damage on landing.

The Old Elektro-UHU (1991)

Someone in my AMA club gave me a Graupner Elektro-UHU still in the box, new, unassembled. It's from 1991. Anyhow, I would like to use a modern power system - brushless motor, LiPo, 60-Amp CC ESC that I have on-hand, and was wondering what components would work best. I'd like to build this Graupner UHU for speed, and at the same time keep the weight down so that it can potentially ride thermals. Secondly, does anyone happen to have instructions in English for the original Graupner Eleckro-UHU kit, because the included German instructions aren't going to cut it for me.

Thanks!!

The E-UHU really wasn't designed for speed. Although the gliding speed was relatively high (too high for many beginners), this was more or less triggered by the weight of the heavy ABS fuselage, the 320g 6 cell SC pack, the 220g motor and standard size 45g servos.

With a modern outrunner, Lipo in the nose and micro servos, the model would fly much different nowadays - have to try.
