YET AGAIN........


MODELFLIGHT AUSTRALIA = FAIL!
AGREED!!!

I have made two orders from modelflight and both times they organised a courier and stuffed it.

I will never directly order from them again. I will get my LHS to order it in and then go pick it up from them.

I think we get stung a bit because we have some of the best chicks in the world here, not to mention the beaches.

Not sure if i will get this one as it doesnt look as quick as the umx beast, as well as it using 250mah lipos.

IS IT AS QUICK AS THE UMX BEAST?

stal your missing the point of this plane the real beast goes FAST! the real Mosquito was a Fighter/Bomber and that is what this micro represents, it's not meant to go as fast as the Beast, i'm sure there will be another Brushless released this season, so people who want all out speed will have something too, this ones for the semi scale buffs

cheers chuck

Real Beast has a top speed of 250mph...Real Mosquito Mk VI was powered by two 1460 hp Merlin 21s or two 1635hp Merlin 25s (beautiful sound!!) and could hit 384 mph and was known for outpacing 109's...but I understand what your saying Chuck as I fly my UMX Beast aggressively and am looking for more of a semi-scale fighter bomber flight style with this warbird.

I don't have the specs in front of me, but the Mosquito was very fast. I think it could outrun all the prop driven German fighters.

Edit: I don't know if anyone has already posted this but listen carefully to the announcer's opening words.

I don't think he was overly optimistic. Even allowing for differences in scale between the Beast and the Mosquito the Mosquito should be noticeably faster.

I bought a new car yesterday so I decided to curb my rc spending. Look what happens, E-flite comes with Blade mCP X RTF. Parkzone comes out with this beautifull little Mossie and the Hawker Hurricane. Now who will be the first to put retracts in the Mossie? A lighting system for those calm summer evening flights would look sweet! Looks like I will have to see about some overtime. You know what would be really nice an Ultra micro Hawker hurricane! No only kidding, please stop making all of these cool planes/helis.

yeah i see what you mean. I have a mini swift here and from what i can tell it should be faster then the umx beast. The rx i have for the mini swift the elev chan doesnt work on it. So im waiting for more to come in the mail.

Stalyoni runs over to his mini swift and pats it while mumbling "my precious"

I like fast areobatic planes myself. I had the hobbyking yak 54 but have a look what happened to it chuck. I know you will get a giggle out of this.

yak 54 crash (0 min 50 sec)


crashed it like 3 times and fixed it up and sold it. The ailerions and the expo i just couldn't get right and it kept tip stalling on me.

Perhaps fitting 2 Nine Eagles Bravo SX (or P47, more convenient since these are already fitted with a 9T pinion) motors might help with speed, provided the Mossy has the same motors as the other UM birds, so you can use the Nine Eagles motors as a direct replacement.


Let's just hope the motor mounts are strong enough for extra pulling power. It wouldn't be cool to see the wings getting ripped off when going to WOT...

Electrically - the motors may not have symetrical timing at the commutator.

Mechanically - mots of these small motors use pressed "finger" brushes which can buckle if pushed rather than pulled.

I may be wrong but with each motor having their own speed controller should they not be turning at the same rpm as long as they receive the same signal?

When you get down to very klow power leves (especially on single cell voltages) the extra current consumed by the microcontroller ina brushless ESC offsets the extra efficiency of the motor - in fact most brushlees motor/ESC combos on single cell operation will be less efficient than the equivilent brushed combo.

Not really... Each motor has a different internal resistance and may take more or less current than the other. As they get older, their internal caracteristics will change, but not at the same time. There's no feedback coming back to the ESC from a brushed motor, so basically both ESCs (or in fact, it could even be one single ESC driving two motors if they would have designed it that way) has no idea which one need more current (larger pulses?) than the other. In fact, it could also simply be one motor with a very thight winding, and one with a loose winding. You apply the same voltage to both and they won't spin at the same speed even if they are brand new. Add to this solder quality, wire lenght, etc and two brand new motors will hardly give you the same speed for the same applied voltage. By using two ESCs, they could also be minor variations in the FETs they have used to control the motors. Keep in mind, that's truly worst case. In production, all those small differences usually end-up cancelling each other. I've never flown a bi-motor, so basically, I was just curious to see if there was some people who have flown some brushed bi-motors and had problems with both motors going different speed, and if so, if there was a way to trim them. Hopefully, it's most likely not needed!

With a brushless motor, there's a way to get some feedback from the motor (back-EMF), so technically, yes, the ESC knows what speed the motor is running at.

I agree with UGN.... You seem to need at least the same space as the Mustang, and the Mustang need a lot of space. One single basketball court is most likely not enough, unless all you want to do is fly it in very thight circles, and try the odd rolls in the long stretch. In that video, the loop looked MUCH bigger than what a Mustang can do (could be just because they wanted to keep it scale looking...), and in some gym, even looping a Mustang is a bit thight (you need all the space you can get between the ceiling and the floor).

Chuck...now that PZ are producing multi-engined micro sized planes....any chance of a 4 engined micro in the works? While I would love a Lancaster to go along with the Mossie and the new large sized Hurricane, I would imagin a B17 would be a huge favorite States side.

I have all the UMs that they ever came out with and will get these as well.
The only disappointment was the micro Cessna with it's brown out issues.

It really cracks me up how everybody gets excited when a new release is announced and then a month after they have it all the negative features are talked about taking away all the excitement.

Maybe one day one will be made that is flawless...not likely though.
