Welcome Nade, Nice helis! The Goblin 630 seems a popular heli around here. I've got one and it's a real hooligan of a heli, I wish i had the skill to push it like it deserves. Here's my 630 last week, nothing very exciting except a slightly dorked landing:

Re: Scratch Built "Weston UK Velocity 50" That should get the adrenalin pumping! Extreme Flight do a similar delta called the 'Outlaw': 36" Electric Outlaw - Red Scheme - - - Updated - - - PS.. Just to give you a heads up. If you have built the wing with a 'flat bottom' type...

I was out this morning flying some of my fleet including a new Blade 180CFX that I picked up second hand but unflown. The fields where I fly are public space so I prefer to fly when there is at least two of us so we can act as spotters for passers by and dog walkers etc. My flying buddy had not...

Phil, Just a comment about swash leveling and zero'ing the pitch at mid stick (screen shot 3) Your instructions appear to suggest that you first level the servo arms, then if the swash is not level or pitch not zero at mid stick you further adjust the arms with subtrim sliders to get the...

I'd not be too worried about the tail blades if it's just 2-3mm... But the main shaft i'd personally want to get right. Having said that if the links can be extended while still retaining a good amount of thread engagement in ball links then it would work ok.

Usually the backup guard would be used to protect from BEC failure. An unregulated Rx pack is so simple and reliable that personally I dont worry about a backup, there are plenty of other more likely sources of failure on a heli, not least me. To be honest I dont use a backup with a BEC...

So how are you going to power the FBL and servos? A 550 is a size where there is a choice to make between a BEC and a stand alone 2s battery feeding your HV servos unregulated. I've got both options on my helis, there are pros and cons either way. The battery wins on simplicity and price but you...

The 'rchelination' 20% discount code should work on the program box too, which should be worth more than the VIP points.

If you are struggling to find the programming box Hobbywingdirect (the US importer) has them: HOBBYWING North America  Multifunction LCD Professional Program Box

Looking forward to seeing what choices you make and the build come together. personally i'd go for the Goblin but the Synergy is a fine heli too. For ESC I'd put a word in for the Hobbywing range. You will get a 20% discount from hobbywingdirect.com with the code 'rchelination'. The 100A HV...

Pumping water as your only 'up/down' control is likely to give very slow response. I'd have thought that supplementing with controllable hydroplanes might be worth considering?.. Real subs all have them. You also have the very real risk that the sub will have negative buoyancy when ballasted...

Thanks!.. I'm lucky, i do have some nice helis. I got the Dune at a good price second hand but it had never turned a blade. It's been a bit of a hanger queen for a few months because it was running a little noisey. That just turned out to be the thrust bearings on the main shaft needed some...

FWIW.. the gyros dont affect the collective input. Essentially when you move the collective stick the FBL unit passes the command straight to the servos. It's only cyclic where the servos dont necessarily follow stick movement directly. If we rule out the possibility of incorrect FBL setup then...

Sorry, duplicate post (why does that happen?)

If the blade grips feel notchy when turned that's hardly ever thrust bearings to blame. The problem is virtually always that the inner radial bearing is getting 'squeezed' too much by being compressed against the head damper, which gives a notchy feel. If there are shim washers fitted you can...

Hi Rodney, I have the Kasama Dune 600. If the new 700 is anything like the 600 it will be an exquisite piece of engineering, absolute top notch quality. They tend to be quite complex with lots or parts which is unlike the trend for low parts count these days, but all the parts are there for...

The fleet looks good Rodney and great to hear that the maiden flight went without hitch. Just remember to charge the camera next time!

I have the 51" AJ Slick... The different size Slick airframes are all scaled in proportion, my 51" version measures 16" 'A to B' so the 74" size Slick would be 23", give or take.

You can upload zip files. So if you zip the .ppd file you should be able to upload it, assuming the file size isnt too big.
