For the inverted i''''m relying on the onboard glow that lights up when the throttle is in the lower 25% range of the stick
Used these before without incident so hopefully it will avoid problems

Just got to connect up elevator and rudder, finish wheel housing cover attachments, decals (might not bother until after first flight as they may prove unnecessary) and balance model and she''s done. Run in one engine, probably do that down the field.



Come on now, a lititle positive waves here! Secrectly, though, I harbor some of the same trepadations when a new bird is about to take wing (and I always prey on one of my good pilot friends to do the maiden-my bod can''t take the extra adrenalin + I get embarassed when the antenna tip vibrates ) I think that I''m a pretty thorough "builder-setup" fella, but there is always that chance that I missed something, which would also be embarassing. My flyin" buddies" don't miss a chance to rub it in, when there is an opening. All in good fun, don''t ya know.

Ran in the new engine over the weekend and then began synchronising the engines, amazing sound! and oodles of power

Status: offline 		I think Alistair is waiting for some decent weather. In the south of the UK recently we have had winds of 28 mph gusting to 40 and with plenty of rain. With all this talk of "global warming" I might have quessed the UK wasn't going to get a share of it!
I too have be watching this thread and are ready to fly very soon. I've been given a crashed airframe and it has now been repaired. I'm using a pair of ASP 61 four strokes fitted with Optiglo II on board glow circuits. I'm going to try some APC 13 x 4's at first, as our club grass strip is quite short. Taxi trials will be held this Saturday as I want to see how the engines perform in the airframe. I'm using a Futaba FF9 (9C to you American Guys) with channels 3 & 7 controlling each engine. I can shut down either engine to idle using switch "C"and also control fine tuning using the left & right "slider" levers of the transmitter. I'm using five mixes on the FF9 and you have to be careful where you put your fingers. Needless to say I won't be flying this bird just yet, I'll leave that to our expert flyer. I don't expect it to fly this weekend but you never know. Whatever the outcome, I'll let you know. There is a great deal of weight in the nose section

Regards Tony

Status: offline 		Hi Guys,
I have ordered my own CM Pro Mosquito and value every ones input especially with the C of G . What is really causing me frustration is what engine size to go for. I have a Top Flight DC3 with 2 x LA 40 2 strokes with 3 blade props and it has more than enough grunt to fly well. The Mossie states 2 x 30 - 4 strokes, so my thought is to use 2 x OS 40- 4 Strokes ( 46 has been discontinued) . But there seems to be preference for lots more grunt quoting 52 size and even bigger. What is actually required to make this Model fly in a scale like fashion and not blast around the sky full throttle at 100 mph. Input would be appreciated thanks.

Status: offline 		Hello,
The big problem with this plane is weight .From what I read here it will weigh about 12-13# minimum
so you need enough thrust to get it off the ground,not so much for airspeed.46la with a low pitch large dia.
might be ok but I don't think so. 40fs is less than that 48fs might be good but no longer sold.That leaves
52fs. 40-48-52-61fs's are almost identical in length and hight.I think you would be very happy with 52-61.
If it's too fast throtle back.With a heavy wing load you need spare power in case of emergency!Hope this
helps.

Thanks for the advice. I just dont want to spoil a long ambition by under powering the model.

I'm sure you wont be disapointed with 52 range FS. Anything less???

I have also this CMP Mosquito and I fly it with two 40 OS LA and perform is quite scale like, take offs nice and speed enough. I can manage loop and roll.

Real problems with this plane are tip stalling and landing gear.

My experiences and some You-tube videos show that tendecy quite clear. There is no dihedral in the wings. Tip stalling is solved because on my maiden flight it went to spin and I had to make new outer wings and they have now dihedral.

Landing gear is something I just try to figure out.

But plane really looks great in the air so go ahead

Status: offline 		OK fella's. Today, we made the decision to power my mossie w/ RCV 60SP's. I had been agonizing over the selection for a lot of months. In earlier posts, ideas were bandied about to make 'em fit; we need about 10 mm additional, and I'm not going to lenghten the cowl, or add material to the nacelles. We're going to go to a metal "can" to, in escense, "move the firewalls back" without actually, physically moving the firewalls back. I had hoped to get this bird into the air this flying season, but access to $$, and dithering about power will now make Spring "09 a more realistic target. More later!

Status: offline 		Hey, bud! In the course of trying to look ahead to try to anticipate/plan for all the issues, it looked to me that I could keep the engines cool enough. I'm not a full bore flyer, even though scale speed for this craft should be higher than most of the planes I have; if there seems to be a cooling issue, we'll just try to solve it. In the past, if our ambient temp was going to be above average, planes with questionable cooling simply sat in the hanger, hopefully to fly another day. Seems to have worked for me so far. I'm always open to questions or comments, so, thanks for the question.

Status: offline 		Hey bud! Glad to see someone else joining the fray vis-a-vis the mossie. A couple of thoughts offered; many mossie pilots have offered up the fact that the balance of the craft requires a lot of useless lead to balance, so larger engines (ie: heavier) would seem to offer some relief in that regard. With that in mind, it appears that 13.5" dia. props are the max you can use. I also believe that throttle management is something we're all used to, so larger engines dont bother me at all, nor shouldn't you. Just do your research to ensure that what you are thinking about is doable. Secondly is the subject of scale speed; since the mossie was a 400+ mph craft, and if scale speed matters to you, then larger can help in that regard. Good luck with your decision. Jerry
