Thanks for the info Looking forward to pics of the cabin and your conversion. Curious how your CG worked out and lipo placement. Mine is the older style kit with forward motor placement, so I'll be moving the motor back under the mechs side frames. I usually don't care for extra electronics either, I just don't want to tax the Vbar power bus more than it needs to be. I run my 800 and smaller size machines direct servo to vbar.

With either the VR22 (older mechanics) and the newer mechanics, there is very little difference in length of the base plate,
The front skid supports are bolted to the base plate, and the gear trains are in the same position

Hi Peter, yes the gear train is in the same position, but the motor is mounted forward in the older version vs centrally in the latest version. I figured that the lipos would need to be mounted further forward to compensate for the missing gas motor. Hence the pic of Greg's lipo mounted in the front dash pod. I'm assuming that the newer version of this heli requires quite a bit of ballast in the nose to compensate for the gas motor being moved aft.

PS. My wife called and told me that the R22 arrived today, ahead of schedule

Ballast
Gregg,has used the New side frames base plate, but I see he has what looks like ballast in the front base compartment
Suspend the completed heli by a 3mm ringbolt screwed into the pre tapped hole in the centre of the head
Lift until the skids at the front of the heli are just touching the base surface
Measure the clear distance at the back of the skids, this distance needs to be at least 1", I always make my distance more, I have a preference for all my helis to fly, nose down (heavy in the nose), even in the hover, (a tip I got from Len Mount many years ago), this is some thing, especially with muli blades, that keeps the wind on top of the blades, helps with stopping ballooning up,
Barry,that is certainly good news with the delivery, 6 days from collection to delivery

Yeah, Greg has 2 of his 6S lipos in the nose and the other 2 on either side of the frames. Thanks for the tip. That's how I CG all of my helis, which is why I liked the idea of you tapping the center hole in the top of the headblock.

Try rolling the heli on a length of tube, (placed across the underside of the skids!) until it balances. You can measure how far in front or behind the main shaft the Static C of G is..

Dave, nothing wrong with your example, works fine on the pod and boom
With a large scale machine scaled up, it is good to to get the CofG correct, across the model, as well as, for and aft
This is where the suspension from the centre of the head is more accurate
All helicopters hang to one side or the other,dependant on whether LH or RH rotation, when flying, once you know how much, you can re adjust the cog to correct this hang, using the suspension method

R22 on floats
Spotted this heli in the photo's at the top of the page
Never seen one on floats

Even more surprising never seen one on a trailer with blades attached

I came home to visit for the weekend and opened up the R22 kit today. This is one massive heli! I can't wait to get started on this build. Thanks again Peter

Barry, you should not take long to build as the hardest part to get correct is the tail boom and drive, that's already done on yours
I took No 11 up to the Watford fly in, to demonstrate it's flying capabilities to the new owner, even in the windy conditions it flew faultlessly, some thing I would always expect from a Vario R22
So get a move on

Yeah, this build will be a little more involved. I plan to mod the side frames and put the Xera motor farther back in the airframe between the side frames. Then I'm going to machine out a section of the front of the bottom plate of the mechs so that the lipos can sit lower in the airframe. I'll machine a bridge to tie the two sides together.

Headroom
The new owner of No 11 has problems transporting his R22, the clear opening in his Mercedes Estate is 769mm the R22 measures 800 to top of head
There are a few solutions to this problem, laying the model on it's side, removing the head, shortening the struts, this last option make the helicopter look squat
I have tried various mods, this is the latest, the wood is to stop the jointers rubbing holes in the carpet, with self adhesive Velcro, this also stops the heli slipping around

my r22 having the same idea on the skids has caused the
bolt holes to elongate and thus no longer provides a
secure mounting
i've had to re-drill the fixing holes and use a
different area of the skid tube for its mounting

as we know my r22 is an older one than that pictured
with the skid modification

Dave, You have been quiet for a while, expected to see you at Watford last weekend
There is not a lot of age difference in these two machines,
Remember I was the original builder of that R22
All things wear with use, and considering it's age, I think it has lasted well if you have only re-drilled once
That elongating of the hole, is caused by the jointing piece getting thinner allowing the skid to shake about, you can fit a longer nut and bolt, but it starts to look ugly with too many nuts and bolts
I have turned these jointers down on the lathe, knurled one side and epoxy'd this into the leg, the free part is quite snug, with only a bolt drilled and tapped into it
Will have to see how long this latest mod works
I have my van, and you your trailer, in our case it would be better just to replace the two front legs, they are available from Vario, and keep the modified ones is case you sell to someone with a small car

but as the winter has been poor i haven't been able
to get the trailer out of my garden
so the modified legs have stayed on
due to work i haven't been able to go to the fly-in
and the way its looking i may not be able to get to many
this year
but i am looking into starting my own business up that will
give myself the control of when i work
