why yes........I couldn't agree more........I've had quite a few great landings....just a couple of stressful ones ... never the less I'm looking for advice to fix the gear until its replaced...by the way what happened the 26th time...me and the plane have over 80 landings[8D]

RE: H9-F6F Hellcat 60 ARF
I'm probably not doing something right, but I'm having a difficult time getting RS 333 RB Lados to fit into my Hellcat properly. The entire retract assembly is at an angle, sothe rake of the landing gear will be too far back regardless if piano wire or RoboStruts are used. As it is, the Lados are elevated in the front (farthest from the wheel\actuator) by about 3.5mm; the back of the mounting plate is touching the surface of the plywood rails. In order to get the retract to sit level, it is needed to remove more material from the spar. However, I donot want to remove any more from the spar area and take a chance on weakening the integrity of the wing.
Please see the attached pics. Any insight would be GREATLY appreciated!

In post 1520 I asked a question about the stock plastic turnbuckels and attaching Robo struts....am I assuming correctly that the turnbuckels stay? Also, does anyone have any experience with the company named Down and Locked...this company retrofits stock mechanical landing gear into electric operating gear..

Look at the pic in post 1508 for the throttle linkage location. It's a straight shot to the servo. The carb on my saito 100 does not move, better check that also.

Sure does, the throttle arm does. I thought you said the carb was moving, my bad.

Hello,
Have you seen a picture of the Torque Link facing forward on a Hellcat? To me it looks as if they did not have one on the pictures I've seen...but haven't seen one close up. It would be great to know for sure; I'm assembling mine over the next few days.

Apparently F6F struts had the knee pointing forward:

The real Hellcat had a Bevel gear on the top of the strut and part of a circular rack to rotate the gear. The Robart 60 size rotating retracts are a variation of this type.

Seen a picture? I've got 3 different "Hellcat in Action" (OK, one is "Hellcat in Detail") booklets. Every picture you can see that detail in shows the links pointing forward.
Bottom line, is that they are really hard to see. The gear door fits very close over the linkages and they aren't very large.
I did stand off scale gear doors from scratch, fiberglassed balsa. The mfg provided ones are pretty awful. The full scale are curved and have a characteristic and significant shape. Mine are close to the shape and real close to the size. And as you can see, the linkage is hardly visible in model sizes.
BTW, I'm not done yet. The doors at the top of the struts aren't done yet. I couldn't stand it when I got it this close to done and had to fly it.

I used the holes already there. Had to move it around alittle to get in the center of the cowling. Also the 100 saito is all the way out on the supplied engine mounts. Hope this helps.

Haroldpo6, did you have to cut your cowl to clear for the valve covers or did they fit inside the cowl pretty good, thanks..

Ok, I've got Robo 650's on the way...I sure hope it isn't too big of a PITA to fit these. And I'm still not crazy about the stock retact mechanism/ball link durability. Lado's sure would be a nice replacement.

RE: H9-F6F Hellcat 60 ARF
Maidened mine yesterday and it's sweet. Very sweet.
I've got the CG a bit behind the mfg's suggested location and it's still a touch light in the tail when ground handling. And flies like a dream. How did I deal with the "less than super safe CG"? Took off on low rates and paid close attention to how sensitive the pitch control was. After noting that, I flipped to high rate elevator and checked out how sensitive it was to high speed stalls and how low speed handling was at high rates. It was good. So now I figure to move the battery further back and know it will still handle good if a bit "sports car-ish". I like sports car handling. And like good ground handling too.
The combination of Robart struts and the new e-retract LADOs I got last week is probably why the thing handles so good. The gear working on landing to absorb bumps looks awesome. And the robostruts don't lean in the turns. Am I tickled? you betcha

RE: H9-F6F Hellcat 60 ARF
Hello All! I will maiden my Hellcat tomorrow evening weather permitting. I had a good time building this plane, the only setbacks were the cowl packaging problem that used to be prominent with the factory putting the cowl in the tissue before the actual paint was dry.. nothing a good cleaning and a quick shot of vulspar clear coat wouldn't take care of. I had an old ASP .91 Fourstroke on hand and didn't wanna spend anymore money on a buying a new 1.00 saito so put it in... the CG came out pretty tail heavy. I mounted the 5 Cell Battery Pack to the firewall like you would an ignition to get the most out of its weight. Now its much better but still tail heavy, I will switch to a brass bailey safety hub instead of a aluminum hub which should take her to just barely tail heavy like you would want... we'll see how it goes, I'm excited about this beautiful bird.
