Sweet Mosquito

Well, my LHS saved one for me today. Picked it up and went straight to the flying field. A couple things impressed me right away.
1. A bit bigger then expected.
2. Three blades look and sound great.
3. Paint scheme and scale looks, thumbs up!
I programmed my DX6i with 30%exp on all rates. On the runway the steerable tailwheel is effective. After taxi, decided 100% full rates for maiden flight would help counter the wind today. I throttle up slowly and full throttle after tail came up and she was in the air in about 5' with 5-10mph head wind.
I did not experience the tail heavy issue as others with the stock battery. The mosquito wanted to climb even at 1/3 throttle. Trim down about 3-4 clicks and level flight a 1/2 throttle looked good. The planes flies a lot smoother in turns then the P-51 would need correction for dipping. Has plenty of power for 45-60 degree climb.
After a few circles I throttled up for a couple of rolls which were slow and managible. The loops were not quite full circle but good enough. She wanted to come out at the top a little to one side like a wing over.
Landing was a non-issue and would recommend keeping 100% full rates on for the whole flight.
Verdict is Awesome First Flight!

Mosquito Throttle Cutout

On my second flight, my Mosquito's throttle cut out after getting into the air about 10' using a brand new E-flite 250mah like the that it came with. Both motors just stopped working. Luckily I was high enough and still had control of the servos. After the smooth dead stick landing, I check the battery connector, check throttle operation and motors worked again.

After second attempt, again the engines cut out and had to deadstick land. I held the plane this time, advance to full throttle and both engines started up and ran for 10 seconds then shut down. What's up with that? I tried it again, throttle down then up and held it and samething happens. Maybe my new battery is not quite charged up. The manual says when power is low the engines will surge up and down as an indicator, but mine as just shutting down.

Any ideas?

I would charge the battery all the way up and try powering it up again while you hold it. If you still have problems try another battery. If that doesn't fix it I would exchange it out or call Horizon.

I'm hoping it will be that simple. Batteries are charging as we speak and I will let you know if that fixes it.

Oh, forgot to mention that my wheels are wobbly to, but did not really bother me on take offs and landings.....yet.

I don't have mine yet, but I wouldn't think It would make much difference with a micro. I'll be flying mine without the gear most of the time anyway.

We are still waiting on this side of the pond (well I am anyway!) i was just wondering about this tail-heaviness...

The manual warns against unpowered landings, suggesting that the glide ratio is not great. I wonder if they have deliberately made it slightly tail heavy to stop the nose dropping after cutting power?

Also, with the wheels being wobbly: Did those who it effects notice it while ROGing? or was it before flying/after reading the thread? And how much difference does it make on the ground? The runway i fly off is no where near smooth - im not sure i would ever notice - unless the wheels were off centre by 2 or 3 mm.

If you have a volt meter that can make those small connections, a fully charged battery should red 4.2 volts or somewhere close. I put a volt meter on the side of the connector where you can see the shiny part of the connector wire.

When you guys say that the wheels wobble is that because there is too much space for the wheels to move side to side?

It's between the Trojan and the Mustang, in terms of agility. I'd say it's closer to the Trojan than it is to the Mustang.

It has a glide slope of around 40-45 degrees. It is not a bird that I'd recommend trying to thermal. The Mosquito is hard not to get tail-heavy. It's got a lot of tail and very little nose.

Yeah - they dont have the luxury of 2 Merlin engines to balance it out

I am sure that PZ could have done more to mitigate the tail heaviness of the plane by moving the brick forward etc.

Maybe they did design her to be a bit tail heavy. Seems silly otherwise - surely it would have been picked up in development?

I'd really like to see some cg measurements from those claiming tail-heaviness with the stock battery. "Proper" cg location is as subjective as paint schemes - everyone has his own preference.

Remember the symptoms of an aft cg are reduced pitch stability (model may appear to "hunt" in pitch), difficulty trimming in pitch, and dramatically more severe stall tendencies such as abruptly entering a spin at stall.

If your model is not exhibiting this kind of behavior, but instead simply wants to climb all the time, you probably just need some down elevator trim. I'm sorry if this may sound a little "basic," but we have a LOT of new modelers here on RCG and we can't assume everybody knows how to trim a model. Also I am trying to sort out if these models truly have a cg that's out of the recommended range or if it's just pilot preference, and we can't figure that out until we get some cg measurements.

Seems sensible

While you're here Dave: when can we expect them in the UK?

I am disappointed that they aren't being made at the old de Havilland factory just up the road from me!

Well i looked at the cg from the stock point and it a little nose heavy with stock battery and with the 500mah 120 sr battery it a little bit more nose heavy. mine in flight tries to imitate a esters rocket at half throttle or above it will try and climb at 50-75 degrees.

it might be my imagination but the tail does not seem parallel with the wing it seems that the leading edge is lower then the back edge.

LOL, yeah like the way the B-29's, B-52's etc dropped some of the early NASA stuff.

Might get her little wings blown off by the prop wash though.

I'll stage a pic when it arrives (soon, I hope)
