Rolling downwind I got huge interaction with elevator. Did a real low pullout and thought WTF? was I really getting lazy?
So I did it again and got the same result. (yeah ok that was dumb) Got back on the ground straight away thinking something was wrong.
Radius block loose and moving freely on main shaft. I didn't tighten it too tight initially as I heard they split. But I did tighten it on the knurling so it wouldn't turn. I never checked it for 4 gallons. (again....dumb) Nearly lost the ship. (lucky!)

Bought blue freya washout and radius block. Fitted tonight. If you have the plastic one then check it regularly or ditch it.

Also....grease on the lower gear and tail rotor drive. Lots of gunk causing stiffer operation. I use the greaser on my bearings. Should clean up the grease a bit more after it flings out.

And...Lower third brg block bearing loose in plastic housing. moved up to contact lower gear. Cleaned and ca glued into the housing. First time I didn't as it was a tightish fit.

Lookout for the screws (in my case cap screws) coming loose on the servo tray. Maybe when I built it the screws locked before being fully tightened due to the heat created by winding cap screws in? Hmmmmm. Probably my own fault. I just hate philips head screws.

And. Fitted freya gear backwards to the evo 50 cause it looks cool.

Next up. Freya tail. Got all the bits.

Hey also....anyone have a devil of a time filing some material off the bearing collars on various arms to eliminate slop while keeping them square? I drilled a 3.96mm hole (number drills) in a piece of wood (on a dril press for squareness) thinner than the collar and then slipped the collar into the hole. (light push fit) and filed the end till I took off the right material. Then ran a drill lightly by hand in the end to create a chamfer and sanded off any rough edges. The filed is held against the wood while filing and the collar pushed into the file from the other side. Perfectly square ends for the bolts to contact and keep your collars straight. I got rid of all play on the new freya washout for my sceadu. Cheap, easy and accurate.

See ya

WOW, some pretty good info there. I'm converting a used Sceadu to an EVO right now. I found the problem with the radius block. I could figure out why the washout and radius block were at wierd angles. Found the radius block loose. Tightened up the screws so it wouldn't move. Now hindsight, I realize they crack. I guess I'll be ordering a metal one.

One of my buddies that has a Sceadu told me to watch out for the 3rd bearing block bearing coming loose. He went to the metal block and still has the problem of the bearing moving up. He used this bearing sealant that he uses at work to hold it in place. I have the metal one in mine also, I never put the plastic one in.

Have you noticed the left tail gearbox cover cracking where it goes into the tail boom? When I got the Heli, the gearbox was off the boom. I went to install it and and found the case cracked. I tore the gearbox apart and a spare half on and found it cracked. I ended up putting the new case that came with the conversion on.

Have you found any problems with the linkage for the elevator? I was putting the pivot balls on the X-type lever on noticed that when I put the ball links on the top 2 balls that they rubbed on each other. I switched the balls around so the 2 balls that go to the elevator torque lever are in the inside and the 2 balls that go to the servo are on the outside.

Did you have to make any new holes in the Freya gear for it to fit properly? Also, is it wider that the EVO gear?

Hi There. Didn't notice any problems with my x lever. did it the way it was in the manual. Haven't looked yet but will.

The freya gear is multi holed so will fit straight on. No it's actually less wide!! But it's a lot lower and I turned them backwards. I used the sceadu skids. They have clamps to hold the skids instead of those awful grub screws that stop you getting the skids out easily. It lowers the c of g on the ground, looks better, sits better and is an automatic spare if I have a whoops with my freya. Thats why i am doing the tail as well.

Left tail box is ok.
cheers

Another Sunday, another order to the Proz. Got the rest of the stuff to get the EVO flying. I live in the 4th largest metropolitan area in the US and not one LHS sells Hirobo stuff. I have to do mail order or drive 150 miles to a shop that carries Hirobo stuff. Hopefully it will be ready to fly next weekend.

yes Martin. was very close. I notice I got some pitting in the top of my hyper 50 piston too. Darn it! I was working very hard to keep that engine cool. I swapped from the red to the CP blue. Had one hotter run and thats what I get. I even richened it up. I cleaned the carb tonight and it looks good. No muck in it. it used to be a nice descent but now I get the waa waas on the way down and can't seem to richen it up to stop it without it being a pig on the ground. got the tail twitching all over the place. thinking about going back to my red mix.

The CP blue doesn't make the smoke like the red. I like less smoke but having trouble tuning. Nice throttle response until just below quarter stick and then blah. It dies. richen it and it's worse. lean it and the engine runs hot. Once it's on the TJ Pro it's fine when the engine was on the CP red. When they come out with electronic fuel injection I'll be the first in line. Tuning these little engines suck at the best of times. (my tuning skills suck at the very least)
