I was at the field today between 14:00 & 15:00 all on my own , good flying too. There is a dead sheep along the fence line towards the gate from the pits, I saw the farmer so reported this to her. I hope no one had plans for a BBQ Smile .

Nice one Gary,
The best gyro on the Market is the Spartan Quark.
Fast lad do combo deals on them and the best 2 tail servos are the JR 3500G and the Futaba 9257.
The absolute best tail servo is the Futaba brushless 257 but it's a tad expensive at around £71.
The motor and esc that come with it work fine,but I changed mine to the Kontronik mini jazz 20 and it worked fantastic.
Cyclic servos wise I'd go with the Hitec hs65 mg's but other good servos are,
Align 420m these are digital and faster than Hitec's
Savox 0257mg same as the Align but a bit cheaper
Then the daddy of all servo's are the JR 287's.
The smaller the receiver the better,I found the 6110e to work fine.

There's a couple of important upgrades,
Microheli anti rotation bracket because as standard the canopy screw goes through the frame into the plastic bracket.
Also the stock belt starts to fray very quickly so if you search fast lads they have a Kevlar belt that's perfect for the job.
Batteries wise the best ones are the Thunder Power pro 45's 910mah.
The Align ones are good too but only 850 mah
The Hyperion's look great as well but I was told the 45c 910's wouldn't fit.

Something essential is a good quality 0.9mm driver and they stock the Integy one which I found to be perfect.
I also found the stock frame screws to be a weird size.
I picked up the imperial equivalent of a 1.5mm driver and it fitted perfect.

Let me know if you need any advise on setup or anything you aren't sure of.
Don't tighten the frame screws too much,just nip them up and let the thread lock do it's thing.
You're gonna like this one mate.

Danny.

Case Heli Guy - £18 (dont go for see through lid, they scratch easily apparently and end up looking crappy really quickly!!

Tail belts bit fiddly to change after build, but not impossible!

My advice FWIW is to buy a magnifying glass and a strong magnet - you will be cursing and dropping little bits all over the bloody shop! Wink

The belts take about 10 mins to change so not too bad.
Something worth doing to make it easier is to get some silicone spray to spray inside the boom.This way the belt slips through much easier.WD40 works but it does eventually eat away at rubber.

The cases look really cool.Something Stubbsy said about the clear one rang a bell,I just can't remember what it is. confused
I was gonna get a case a while ago and Mark said not to get the clear one.
I can't remember what the reason was.

Mark are you there?

Sound mate,it's a cracking gyro the 780.
It's really easy to setup,literally 30 seconds and it's done.
Are you still planning on using a servo you've already got?

Gary I forgot to post a link for you.
http://www.helifreak.com/index.php

It's worth looking there for lot's of info on all heli's.
Checkout the 250 section halfway down the page and have a look at the build videos.
It's the best site I've found for heli info.

Enjoy

Hi Gary good choice the GP 780 and as danny said it is a cracking GIRO,
do you have the matching DS420 Servo?

I have these on my Mini Titan and they are superb.

Hope you have lots of fun with the 250.

Steve

Tha Align 420 and 520 servo's are handy because the 250's esc has adjustable voltage.
You can adjust it from 5V to 5.5V to 6V,and the Aligns both are rated at 6 volts.
Most Futaba and JR tail servos are only rated for 4.8V so if you want to run the cyclic's at 6V it's worth running a 5.1V stepdown reg.
Which ever servo you use have a quick look to see what it's rated at.

Are you getting excited yet?
