The OS#7 plug is a hotter plug than the OS#8 so you will probably need to tweak the needle settings to get it running right.

Dont get the bearing from FL or any other high street/internet heli stores as you pay through the nose for it.. £20 for rears alone

get them from SKF 61902 Open Deep Groove Ball Bearing 15x28x7mm Simply Bearings Ltd if you want SKF originals.. and they are at half the price at £10

here RCbearings.co.uk, For a friction free RC! for the price of £2!!!!!.. thats 10 sets for the price of the originals and imo.. lasts alot better (As i'm yet to change them compared to originals!)

I use a local company, give them the size I need and tell them the application and ask for the best. They then charge silly money, and by this I mean peanuts for a few of them delivered

Essex bearings. They specialise in bearings from tiny to massive huge motors etc

Hey all my align 50 h was in my 600 for 3 years and has only been taken out for a 55 the 50 would have had around 100 gallons threw it. all that it got was new bearing every 100 flights or so and a new piston and ring a few months back due to a lean run because of a leak in the fuel pipe, but in all those flight i had with it it performed faultlesly ,it was only when i got a flight on quite new 50 h that i saw a power difference and rather than put a new liner in i got the 55, so in my view the 50 hypers have proved themselves time and time again and im hoping the 55s follow in their foot steps
