    Status: offline     		Well, I decided to look at the exact prop I have on it....is it a 15.75 x 13! No wonder why it was not running anywhere near full rpm. I remembered that this prop was the only 3 blader my lhs had in stock. Shame...the APC is prettier than the MA and it looks as if the spinner was cut for this very prop.

    Status: offline     		Sessholvlaru, that's a shame about the dead-stick and a real pisser about the mechanical retract servo not having enough umph. Wonder if that servo would work on 6 volts? I have some 3-1/4" thin foam wheels that I intended to use, but if the purpose built servo can't handle your's I'm not sure what's up. I am using the Futaba 180 degree retract servo and the gear seam to cycle on the bench fine. I may throw a 6 volt battery in the system just to see if the servo operates.

    For this model, I'm staying away from air retracts. Too much extra weight.

    Status: offline     		Well worse news today. Both elevator halves left the stab after a dive. Plane went into the weeds hard, but is not too badly damaged. I think I might just save up for another and use this one as a spare. I beefed up the stabs, moved the servo to the rear and sealed the gaps. Most of the CA hinges broke in half while two pulled out. I am guessing that Ace cannot help me with this issue, but I guess it can't hurt to inquire. Now I know to use Robarts instead. A real shame...second flight and I was really starting to love the plane. Oh well. I am uploading some pics and video of it in the crash forum.

    Is there sufficient hardwood to accept the Robart hinges? I've been eyeballing this plane for a while, and now that you guys seem to have most of the kink's worked out...

    reincarnate,

    Run, don't walk away from this plane! I say that half-jokingly but I have one sitting upstairs, perhaps someday I'll take another whack at it but considering the mods required and the time you'll need to put into it, I'd have to say if I had it to do over again, I wouldn't...

    No there isn't, the trailing / leading edges of the horiz stab / elevators is ~ 4mm thick. Same issues with the wings / ailerons, but maybe 5mm thick. When I assembled my Rare Bear, I opened up the various control surfaces and added hard balsa blocks for the Robart hinges.

    The wings look quite nice and the fuse fiberglass looks well done...

    a YS 110 should pull it around well...

    Status: offline     		Hi Guys,
    I am building Thunder tiger Rare Bear, and would like to know what size 3 blade prop should I use. I am not sure about the engine but I might opt for OS 91 or OS 120 AX in Rare Bear. Please suggest appropriate prop size for both the engines.
    Thanks
    Asif

    Status: offline     		Hi

    I have a 91 and are running a 12x8 (3-blade) and seems a good combo for the motor. Doesnt quite look scale, but if you want a bigger prop your going to need to go a bigger motor or 4 stroke. The 91 has plenty of go for the plane, though I had to add about 450grams of lead to get it to balance.

    Cheers.

    Status: offline     		Hi lil-redrex,
    Thanks for your reply. Do you think 13x8 would be overload for OS 91?
    How is the speed of your aircraft with 12x8?
    Thanks

    Status: offline     		Hi

    Not sure, I bought one to try, but havent put it on to compare.

    Someone else in this thread was running a 14x7 on a Super Tiger 91.

    Mine runs at about 10,000 rpm with the 12x8 (master airscrew) on the packet for the props it says the 13x8 is for 1.08 and up size engines.

    I have only had a couple of flights, but the speed with the 12x8 seems pretty good, has plenty of pull and lifts off the runway quite easily on takeoff.
