Status: offline 		g62 will have plenty of power for this plane,plus that extra 20 some odd ounces is not gonna hurt it.besides,with the zenoah,i don't have to cut a big gaping hole in the firewall to clear a carb,and,that zdz 50-60 won't turn any bigger prop than the g62 will.

Do you work for ZDZ? If so why don't they make that 80 CC inline twin..

I am far enough along to make the first true weighing of the plane. Looks like she will be around 17.8 pounds ready to fly. Very pleasing to discover.


Splais:

Did you have to add any nose weight? In an earlier post, a guy mentioned that he will have to add tail weight with the US41, but I know your motor (DA50) is much lighter.

Status: offline 		Hello, this is a response to those that are planning to run the fixed landing gear. I have the WM GS P-51D and my flying buddy has the Hangar 9 1.50 size P-51D. Both planes have a Moki 2.10 spinning an APC 18x12. His was radared at 130mph straight and level and mine comes in slightly behind-125mph.
I've been using the mechanical retracts and have recently had a problem with the two servos that has forced me to lock the retracts down and unplug the servos. This allows me to keep flying the plane until I can afford Robarts, SpringAirs, etc.
Here's my point--We normally fly wide open and in somewhat of a formation. Kinda cool to watch, if I do say so. However, this was the first day that I've had to lock the retracts down, and my buddy had to throttle back to half throttle +/- while I was still wide open to keep us at the same speed. WOW. I did not know that the gear produced that much drag. Still fun to fly but it is definitely slower.........
Will need to get some good retracts soon.

Status: offline 		This is the totally complete fuselage interior. I relocated the receiver to below the cockpit. Used the black fiberglass tube they sent by mistake as an antenna tube. Note the Sierra air valve. Much sturdier and easier to adjust than the Robart valve. Note how I attached the quick disconnects for the air system in opposite directions. This allows you to connect the two ends together on the fuselage and wing when not flying to keep dust out of the system. I did make one mistake. I installed the right elevator and tailwheel steering servos backwards, directionwise. Doesn't seem to be a problem. I used two heavy duty MPI combination charge/on-off/indicator switches (have the little power indicator lights on them). I have a complete 12" of clearance between all radio gear and all engine gear. The entire setup came out quite well.

Status: offline 		CAUTION!

I hate it when you are cruising along on construction and then something happens. I was installing the canopy. I taped it down a couple places and drilled my holes. Well when I pulled the tape up it PULLED ALL THE PAINT OFF THE CANOPY were the tape was! So beware. On examination it looks like a lousy paint job that will start peeling off in no time anyway.

PS: Even more of the paint came off. I tried painting it with Lustrekote Aluminum. Didn't work worth a damn. They need to have brush-on Lustrekote, they don't. Going to take major work, Tried Testors, worked OK, but can't match the color so now the canopy on my beautiful P-51 looks like crap! Has big messed up two inch spot on the side.

Big PS: the canopy install instructions are completely unsatisfactory. By the time you get to the install instructions everything else has been added inside the fuselage. You can't get to the screw holes to reinforce them form the inside. Of the 8 holes I drilled, 3 were to big for the small screws. The canopy should be positioned and the holes drilled before you put anything inside the fuselage. Put some supporting blocks behind the holes, CA reinforce them, and you are set. Then you can take it off and continue with the normal assembly instructions.

Status: offline 		Thanks for the advice on the canopy. I just installed the air tank and all of the servos. Started the engine installation. Did any of you decide to mount the engine directly to the firewall, or are you using the G.P. mount they reccomend. I have one on my Giant TF Corsair and seems to work OK. The G-62 causes a lot of the bottom cowl to be removed. I will cut out for the carb tomorrow, and hope to have the fuel system installed with the throttle servo.
Gett'n closer

get some aluminum tape or flite metal and burnish onto canopy frame. Relatively easy to do and looks a hundred times more realistic. Actualli it would be cool to recover the fuse in flite metal and burnish rivets... humnn?

Status: offline 		Guys,how can you take a beautiful plane like this and butcher the cowls like that?
ICK.
Anyways, the planes look great,those wheels look exactly like robart scale allum ones,they range in 1/4 " increments 4" to 6" I believe, $90 a pair,sheldons might even be less.
As for the mokis,I know there messy,but you cannot beat the power to weight.
Once a moki is broken in (yes that part is a pain), it is far and away the best engine I have to start.I wish my gassers started so well.
Fill it up, prime ,and hand bounce the spinner backwards to compression,starts first time ,every time.
If you use store bought fuel, it can get pricey,but since moki's run best on no nitro,mix your own,and its a lot cheaper.
Good luch with all those runstangs guys.(little aces high humor)

Status: offline 		if the 615s arnt gonna be strong enough for the flaps, what is ? 645s ?
are 615s ok for alerions ?
those flaps must do a hell of a lot then. im not personaly big on flaps. i dont use them to land any of my other planes. but i thought i might try it with this bird. i cant belive there gonna be that much of a problem.

Status: offline 		There is not a problem, they just need strong servos to hold the flaps down. The 615's will work fine on the ailerons. The ailerons need at least 80-90 oz. and the elevators should have between 90-120 oz. each. The rudder is the same. This depends on what you are going to do with the model. If you are going to fly it like you were in the aircraft, that means no nine G turns or pull ups etc. You should have no problems. Also if you don't use flaps on landing expect the plane to float forever in ground efect. The barn doors will really slow her down and shorten the landing roll. Just my experence with mustangs. Hope it helps.

Status: offline 		Canopy attachment
Splais, You might want to try gluing the canopy on after you get the paint fixed. Canopies attached with screws generally dont last. The screw hole is a great place for a crack to start. I glue all of my canopies on with RC56 canopy glue. It dries clear and sticks great to monokote. Best part is, if you ever have to remove the canopy, use an old apc prop and slip it in the glue joint, pry it off all the way around and you will be able to re-use the canopy again. The old glue will peel off the original canopy. I did this on my world models P-51 MA and it worked great.

Status: offline 		I have some of the RC56 and will probably use it. Most of the wood were the canopy screws go is very soft and thin. Even with CA reinforcement I think the screws will pull out in short order.
