Status: offline 		A very close friend of mine has dropped a project off in the shop with interesting lines and heritage...and she's wall to wall assembled...114" of pure twin engine WWll delight...what a select jewel...I look forward to her maiden in the near future...she's of Greg Hahn origin and build...Ziroli design...she's been through a couple hangers...understandably has a few head knod's in her history...and now rest here... ...superbly built and modified by Mr Hahn himself during construction throughout....a good thing of choice, but...we'll get to them Mods later...lol...but such a great piece of RC that shows very little signs of her age... great craftsmanship throughout...we gonna part her down to the glass and epoxy on the inside, and bring her back pristine flying once more...we hope to keep the same basic items for flight, minus some minor things more modern suited for us, but nonetheless, bring her back up to speed for a few more Sundays of joy...I'll get up some pics and show a little as we go...please chime in here anyone...anybody flying one...I'm excited to be rebuilding such a classic girl....Bill

A friend of mine and I built and fly the same model. We opted for the scale ailerons and spoiler version. Ours has two G-45's with on board FEMA starters, Robart gear, wheels and brakes and we take turns flying it. We opted for 2 transmitters - one for the basic 4 flight controls and brakes, and the other for flaps, retracts and starters. It flies great and you will really enjoy your new model.

What engines are you going to use ?

Jerry

The on board starters are from Germany (they were sold here by Hobby Lobby). They work great !! They run from a 10 cell NiMH pack of 1300 mah and we can run them for a weekend without any noticeable reduction in cranking power. The electric motors spin the crankshaft at about 1500 rpm. There is an automatic clutch that disengages as soon as the engine starts. The motors and gears take up some room in the nacelles, so I opted to place one 32 ounce tank in the center pod and feed each engine with it's own line and clunk. It works great and after a 10 minute flight at full throttle, we still have 12 -14 ounces left.

It flies well - not as nimble as the average warbird, but has a lot of presence in the air. It will do a full aileron roll with the scale spoilers. Rudders are very responsive at all speeds. It goes where you point it, and we land it with just half flaps. The flaps are enormous on this bird and half flaps seem to provide the perfect balance between lift and drag. It will tend to float in ground effect. You will have to practice the takeoffs - as this warbird tends to leap into the air. That's not a problem, except it doesn't look at all scale. Gain plenty of ground speed and gently pull back on the elevator and it will just fly right off the ground in a nice flat take off.

I know you will enjoy this bird, and I wish you well - you don't see many of these at the fly ins.

His P-61 went through a couple owners here in South Florida, and flew from our field.
Glad to hear she's still flying.
