429 mechs
well I have had this thing sitting for too long because its missing several parts including the mechanics. Since customizing a set of mechanics for my Roban Astar with much success I thought I would give a set of doghouse mechanics for this beast a shot. the mechs is truly a Hybrid as it uses parts from several brands.
bearing blocks from align, tail boom and gearbox from MAS, century four bladed head, thinder tiger main gear, Bergen clutch and bell, and the list goes on. I finally hoverd the mechanics for the first time in the back yard yesterday and exept for a weak tail, it was solid. I later added a cascade four bladed t/r and now its locked on with yaw control. ordering more G-10 sheets for this one too

Thanks guys, Ed you are right. Altho I am not knocking the Roban mechs, they do work, I have seen them smooth, quiet and trouble free, I find a few features not to my liking. I guess I have always been inspired by the way people like Darrell can design and build his own mechs for his giant fuselages. If I had the equipment he had, man I would be dangerous lol!
Anyway, a few more flights on these mechs and it will be mounted in the fuse next. in the meantime, its back to the Astar, the nats are just around the corner.

Emile stopped by my house this weekend to pick up some items I was holding for him and to test my 429 mechs.
He brought along his homemade mechs and I was very impressed. The mechs now sport new G10 frames which he built using the wood template from the temporary frames.
I can't wait to see these mechs in the doghouse of his big 429.

yep, I have the mechs flying and working out gearing for the tail rotor drive. I have a few ratios to choose from and zeroing in on the one that works best. after that's all squared away it will get mounted in the fuse for those first test hops.drive a rotary, fly a rotorcraft

got the mechanics dialed in nicely. Its very stable with the blades I am running altho they are a mismatched set, one pair are MAH 690mm flat bottoms and the other pair are a set of rotortech 700mm symmetrical blades. I didn't have two pairs of identical blades to use so they will have to do till i buy a couple pairs of the same. anyway, I started the process of setting the mechs in place and mounting the tail rotor gearbox in the boom. once that's done, I will mount the boom to the main body and make up a tube drive that will reach.

what T/r gear box are you using Emile? BTW only you would stick two different sets of blades on and go fly the thing..!!!! and I'm betting with no flybarless unit..?Home of the "Sea Cobra".....

Jim, you're right lol I'm crazy like that and yup, no fbl unit, at least so far it doesn't need one. Well see what it feels like in the fuse. That is a std tr gearbox from an xcell 60. Its a very compact and universal gearbox.drive a rotary, fly a rotorcraft

LOL...you crazy bud... I can see using mismatched blades on opposite sides of a 4 blade head, but flat bottom vs symmetrical? Gotta love it

yeah, I was like, what the hell, I will get em in track and go, so far unless I think about it, its been no issue at all, just like they were all the same. see, there are no set rules with some things in this hobby. I don't intend to leave them that way but for now while everything I do is an experiment and test flight, they will do fine drive a rotary, fly a rotorcraft

airborne at last!
finally I got this beast in the air with the fuselage. I gotta admit, I still get nervous on those first flights in a fuselage, I am always worried about ground resonance, by the time you see it coming, its too late to do anything and it ends up a mess. anyway flight went well, smooth and no issues.

Good work man!! It's my turn to feel the pucker tmr. I will maiden the AS350 tmr. It should be fine but I can't help feeling shaky. I did a static ground spool up to 1275 rpm and sat there at 0 pitch with no issue's. Only one thing left to do [crap my pants] put it in the air....Dennis
