Adrian Larkins: I'm not a model maker. I wish I was. I am however a old retired pilot who takes a big interest in scale models. Realism is everything in my view. Bravo for going to a 4 bladed prop. The thing is, having achieved that, why spoil it with that engine? I repeat, I'm not a model maker but would it not have been possible to fit a Kolm engine, say 3 or 4 cylinder. The aircraft would then look and sound like the real McCoy.
Vijay Patel: Does the fiber glassing increase the structural strength?
Bob Rosso: oh that bitch is sweet
dsarnold: Who did your prop shaft extension? If I wanted to duplicate this what would I need to tell a machine shop? Thanks.
Allen Smith: I like how at the end they all take a picture around the p-51 like it's a hunting trophy. One guy should have a gun.
ace trex: Sorry to burst your bubble but that's slower than hell!!! And annoyingly loud!!
Fred Culbertson: I do agree with some of the comments on the muffler but no other opportunity was available. This is an 86 inch wingspan Mustang so we were limited on options. To get it to fly on a 4 blade we had to use the DA 85. Since the plane was built as a 50cc class bird the 85 was a tough fit. There isn't any room for scale exhaust inside the cowl and there isn't any other exhaust options for this build. Yeah, I hate the muffler sticking out as well but it is what it is. The point of the project was to see if we could get it to fly on a 4 blade and a 50cc engine doesn't have the rpm range or torque to produce the amount of thrust needed for a scale prop on a plane this size. You can't turn the 4 blade over 6100 RPM in flight because of cavitation and the 50cc engines would overheat trying to replicate the lower RPM. I would rather see the large 4 blade prop (with the ugly muffler) than a 2 blade mustang but thats just my opinion. This build is around $5000. If you want to go to the next level and put in a 3 cyl inline and a reduction drive with a 4 blade you would be looking at a 100 in wingspan and a total build price around $12,000. Hopefully one day we will have an engine setup for the 86 inch wingspan warbirds that will produce the needed torque and a better muffler (or hidden) system.
P Slatts: why would you go to all that trouble- 700hrs work.. scale look with metallic covering.. scale four blade prop.. then have that f*ugly Pitts muffler sticking out like a turd floating in a pool..and yup sounds like a Sunday in the burbs homelite weed whacker.. P51 score card fail.... and just one 'big ad show for the sponsors'.
Law Less: What wingspan is it?
boxeater406: What, me worry??
Bernie Skenandore: ... world's biggest toy box. my dad flew a real one in china. 14th A.F. 'Flying Tiger'. i have a piece with an enemy bullet hole in it (real p-51). 25 grand? What a rush. Whoa! Thank you.
Steinwaygrande: Very interesting. I built a 1/5th scale WW11 Hawker Hurricane in 2002 and finished it in late 2003. The transmitter and receiver are from Futaba ( Field Force 8 ) and the servos are all Futaba 3001`s . My very first R/C model was the old Precedent Hi Boy , and the transmitter /receiver was a Hitech something or other. Biggest waste of money and incredibly unreliable, that it caused me to lose two aircraft . The radio or the receiver failed on more occasions then I care to remember. Went out and bought the latest state of the art Futaba Field Force Eight and never looked back. I guess Hitec have now got their act together and are making some good products, and ironed out the bugs that plagued the early models.
