Thanks, Rclab...

Hi Papangue!!! So we learn quickly
1. Check rudder dirction.
2. Check propeller bolts and nuts. not too tight.
3. Check surrounding. Any electrical air cables...
4. ?
But it seems that you can fly!! It also looks as soaring air!
Good luck with your spare part! And nice to see that camera did not brake. Thanks for sharing. God bless /BG

Nitro now carrying diamond 2500

Just a heads up Nitro planes just started carrying the Diamond 2500. Its the version with out flaps installed.

$209 including shipping! Quite a bit cheaper than bananas 5 channel model.

I like this paint scheme "better" than the w/flaps model. I think there are other minor differences as well. Like lesser motor and esc (40a vs. 60a) but not sure what else. Oh yeah 4 channel radio which I would ditch anyway.

Think I'm going to finally pick up one of these.

Anyone one have any thoughts on whether or not hitec hs-55 servos will be ok for the flaps? I have a couple spares laying around.

so Im thinking of buying a sailplane like the Robbe or the Artech ones seen here. It looks like fun! I want to have a videocam like the one here attached (http://hobbyfly.de/en/new-rc-product...-pnp-3450.html)

my question to you people (if you know anything = which I believe you do! is how difficult is it to fly these things and how and where do I buy a camera like in the video from hobbyfly.de?? also saw somewhere glasses which you wear and through which you see your flight real time which would be so cool. I would ideally like a plane that can fly very far, fast and that is robust enough to land on grass..and Im thinking video because I cant understand how you guys see the planes when they are 1mile south and 200ft up, I mean how do you even know which direction you are flying then??

btw. those jet planes can they land on grass or only tarmac?

Thanks folks if you can help me out here and please Im not looking for advice such as start with a beginner airplane etc.. I can afford to crash so I want something fun and impressive from the get go

better buy a few!! YOU WILL CRASH... I will NOT even attempt to try to tell you how to go about "learning to fly"...You've seen how easy it is, right?

Hi All,

I can't believe it been so long since I posted. Time flys by. Being secretary for a new RC Club seems to take up a lot of my time at the moment. Have to do the necessary paperwork for 35 members. But for a new club to reach it's limit and have a waiting list after 1 month is pretty good going.

Have had a few good flights this year already with my Diamond and have attached a Fly Cam Evo to it recently to see what video I could get.
First attempt below.

Will be trying some different angles and views over the coming weeks.

Does this glider thermal or slope soar as well as the other foam gliders? Let's find out!

Take a look at this thread and give me your thoughts.

I haven't used mine much, but from users of this Plane,
its a fantastic deal for a 2.5m plane !

Value is in the eye of the beholder. When I buy a sailplane I judge its value based on how well it soars. If it is cheap, but does not soar well, then to me it is not much of a value. But others value things differently.

Fabruary 9th Flight

Hello Diamond 2500 pilots,

I had nice flying day on Fabruary 9th. Here is my video from the first flight this day. I used 4500mAh 15C 400g battery. Hope you will like it.
Létání v Přáslavicích 9 Únor 2011 for YouTube (11 min 27 sec)

I will try to show you also the second flight from this day with genuine 2500mAh 20C battery hopefully sometimes soon (takes some time to prepare and upload and to have enough time to do that) .

Hi PAV, nice flight and video...what's your impression of the flight characteristics of your Diamond, when you use your different size batteries?

It is completely different feeling. I feel that that heavy 400 grams battery is good in windy days . But since it is just 15C, it is slower in climbing, I need to be patient and climb slowly, but I like the taste of this two completely different flight characteristics with this 2 batteries I have . I learned recently that it is not necessary to go way: full throttle and zero throttle . I use throttle values in between as it is necessary during the flight and to avoid not necessary too fast flight and probably to save the battery during the flight. Genuine 2500mAh 20C battery is fast in climbing ! and I feel that it is more safe with this battery during takeoff in comparison with the 4500 15C 400 grams battery. But it is not that heavy, so in a wind, the wind is able to play and control Diamond 2500 little more eg. if you try to turn the wing or try to climb against the wind. I feel more safe in the wind with the heavier battery . I observed that for lighter genuine 2500mAh 20C battery, it is better for me to limit amount of control by 70% with 70% control limit button with the genuine Diamond TX. It is better for controlling to not to have the control so much sensitive to little changes. With heavier battery the Diamond 2500 is not so sensitive to TX so I have used 100% control amount during the flight recently. Lighter genuine 2500mAh 20C battery is even better for gliding . I also purchased even lighter 30C 2160mAh 4S 240 grams battery, but did not test it yet, since there is different connector. But surely I will send a message how it will behave for me.

TBS Crossfire or DragonLink?

Diamond 2500

Hello all,
I've been skimming through these pages and the Diamond 2500 looks like a great glider.... I have several questions
Please be nice to me

1. I plan on using 4s 4000mah Lipo


What is the flightimes you are getting with similiar battery?

I plan on flying heavy because its windy where I live
and I plan on putting my digital camera on it (8 oz).
So with the 4s-4000mah Lipo and my camera (8 oz),
it will be heavy.....

2. is this a Limited Motor Run "LMR" glider?
What I mean by that is, do you guys keep full throttle "WOT"
only for 30sec, then glide around, to let electronics cool off?
....and thermal around....

3. with the 4s-4000mah Lipo that I want to use,
if I go all out "WOT", what is the average flight times?

(I know it would help if we get the amps of the Stock
power setup that comes with the Diamond 2500
to determind average flight times)

4. how much Watts is the stock power system?
....ie ~500watts with the 4s Lipos we use?

5. Banana Hobby ~$240 with Flaps
NitroPlanes ~~200 w/o /Flaps

Do these planes have the Same Motor?

What I plan to do with this plane is fly around a bit with
motor constantly "ON"..... there are no thermals where
I live b/c its very cold outside.....

I hope it can fly with Motor constantly "ON" for longer than 25minutes.?????
I know I'm not going "WOT" all the time, but the motor will be "ON"
a lot.

can someone post a Video (not onboard camera) with the
Diamond 2500 flying around "WOT".....

sorry for all the questions, but I got excited about this bird

TBS Crossfire or DragonLink?
....also, the stock motor? what is the specs on this motor?
size, weight?

What Scorpion Motor is equivalent to this Diamond 2500 stock motor?




most likely the 3020 Scorpion since its closer to >550 watts on 4s Lipo.....Wow!

Hi PAV....great flight summary regarding the two different sized batteries. Your ability to become familiar with the slight variences and changes will let you "feel" those thermals,...and i have no doubt that you will become a first class sailplane pilot...You're on your way!
