Last winter was our worst for 30 years. Lots of snow and cold temperatures. Living in the UK you just take your opportunities to fly when you can as the weather is so unpredictable here. Our summers can be pretty bad and our winters fairly mild. Some years we have scorching summers. If it's dry and not too windy then that's flying weather even if it's cold. I think that's why Brits are so obsessed with weather. Outsiders don't quite understand our obsession until they come here!
Well, that can be frustrating. I am glad we don't have a VAT here in the states, but, that could change soon as I recently read that the govt has been kicking around the idea. Don't know what your weather is like there at this time of the year, but for many of us in the northern part of the U.S. the flying season is about over for the winter. Check out the "anti-crash foam" thread in the off topic section for a look at last winter's weather for many of us.

Very good, football not soccer! Btw, Sheffield (where I live) is the home to the World's oldest football club, Sheffield FC. They're semi professional. Sheffield has two professional clubs Sheffield United and Sheffield Wednesday. I support United and we lost again today I know I'm not out in that weather! I fly indoors at an indoor soccer field. Whoops... for you sir.. football field. Scott

Anyone else used the adapter plates for mini servos? Seem like I'll have to file away some of the frame as it partially obstructs the holes for the mini servos The design of the adapter plates/frame just seems wrong. If the holes were fully obstructed by the frame then that would be fine as I could drill new holes in the frame. As it is I can only secure the servos by filing away a part of the frame then using a screw and bolt. Pic below. The Ino Lab tail servo is too small even for the adapter plate! Should have looked at the measurements for that one. Though it is designed for 500 size helis. I could end up mounting it on the boom or try and make a different plate.

Can't help you with the adapter plate. I've never used them. I would simply drill new holes in the plate, or try plates in different locations. I don't hold much hope for the latter but the former sure is doable.

Cheers. There's no room on the plates to drill new holes. But the plates aren't really the problem, my servos fit the holes on the plate. The problem is there is nothing for the servo screws to secure themselves to. The only solution is file the frame a little and get some M2 bolts and nuts to secure the servo to the plate. Even then the bolts will probably hit the cross head screws used to secure the plates to the frame. Actually it's the plastic holders on the servo which hit the cross head screws. Anyway, enough talk. I'll be hitting it with the Dremel tomorrow. Can't help you with the adapter plate. I've never used them.

Well... LOL! I told you I never used them. Seriously... I'd just grind the frame a bit like you're going to be forced to do, then. I would have thought they'd have caught this at the factory. Scott

You'd think so I think I'm the only person to have ever used the adapters. I've already given Gaui some feedback ;D Well... LOL! I told you I never used them. Seriously...

I'm mounting the servo on the boom. Anyone any ideas on a straight tail pushrod I can use? Gaui list one for the 425 (204670) but you can't buy it here. There's also a pushrod adjuster by Gaui (204661) you can use to secure two pushrods together but again I can't find one in stock here.

I think you will be ok taking a little off of the frame to make the servos work. Keep in mind that it is the same frame as the 550 and was designed for full size servos. All mini servos do not have the holes in the same place and there are several adapters available for different brands of servos. I actually had a little different problem when mounting my JR 3500 tail servo which is a mini. It did not match up with the holes in the adapter plate as it was a little smaller and there was not enough material to drill new holes in the plate. With a different plate to match my servo, it would have cleared the frame, unlike yours. I think Gaui just threw those adapters in without giving any thought as to whether they would work properly.
I mounted mine on the boom since I had some electronics in the way of the frame mount. Unfortunately, I used the 2 parts that you mentioned above that you were not able to find locally, so can't really help there.
You might be able to find a control rod splice block for another brand of heli with a 2mm control rod, I dunno. Or, you could check to see if anybody near you has the control rod kit that comes with the rod and adjuster both. ( Part# G-204660 )
EDIT; I just had an after thought on the adapter plates even though you probably already modified the frame by now. You could mount the servos to the plates with bolts and nuts, then cut the bolts off flush with the nut. Then space the adapter plate out enough for the nuts to clear the frame. ( I thought about this while looking at your thread over on Freak, and posted a reply there too. )

Cheers Jerry. I checked on the control rod adjuster you mention and it's out of stock at the one store selling it.
I decided to buy a carbon rod and make my own push rod. Good thinking on the adapter plate! That may work. I'll take a look.

Still awaiting the nuts and bolts. I got a pair of the link tightening trinkets and ball link pliers today. These pliers were very cheap so I just took the risk and ordered them. Fortunately they fit the Gaui links nicely.

Very cool. You'll thank yourself time and time again building links. Do me a favor and feel what you'll be missing, first. Make one to length, then do it with the tools! Be careful snappng the links on the balls. I'm talking really careful. Use the tool and make sure it's lined up. I'd hate for you to snap a link end. Scott

I never knew such a tool existed until I started this thread! Before I got the thread tool I'd already done the mixer links by hand and the pain was excruciating! So I really appreciate these little gizmos. Essential for bigger helis. Yep, one thing I've noticed with ball link pliers is you have to have them lined up perfectly. Only had one mishap so far with the links and that was when one split today when tightening. Must have been a bad one as it had barely been tightened. Very cool.

The one piece L45 links are the ones people have had problems with breaking while installing them. I read many comments from people that broke them on the 425 kits. I think Gaui got a 'bad batch' of them that went into the 425 kits.
I had no problems when putting my 550 together a couple years ago and even I broke both of the L45 links in the 425 kit when I put it together. If you look closely at the pics of my 425 in the photo thread you will see that I ended up making two standard adjustable links in place of the L45 links.

Oh right, I'll keep an eye on the one piece links. I ordered a couple of pinions the other day, a 13t and 14t. Of course they sent me the wrong ones and i got a 14t and 15t The 14t is the one that looks ideal as it should give me a head speed of around 2700. 15t is just under 3000. I may keep the 15t they sent me in case I find myself doing harder 3d stuff. 13t would give me 2560. Perhaps a little low.

I have never actually "tached" my 425, but I am running a 1470kv motor with 15T pinion, 50T primary, 20T OW, and 61T main. I think I 'calculated' it at around 2800 and it flys really well. I had a 16T pinion in it for a few flights and the head speed was scary fast, but it was real hard on batteries. I was only getting 3:30 flights with a 6s 2500mah battery.

They look nice. I almost ordered them a few days ago after seeing the link earlier in the thread but couldn't really justify spending that much as the moment. They're £22 here. But I will get a pair one day as it's never worth skimping on tools.
