Had the 14th flight of my DH Mosquito today ...

All credit to the Aerotech co. the model flies great ....... quick and easy to build and looks the part in the air.

I'm looking forward to the next flight already.

Please share the specs with us....Nice color Scheme!!! Do you have retracts?

f104g,

Could you share some ideas with me? I am new to twins and have a Great Planes Super Sportster 40 converted to twin Fox 25s per a article in RCM several years ago.
Have made several flights but not yet happy with results, ie have also made several repairs!!
Both engines bought new, same break in. I installed a left hand crank in one to make the engines counter-rotating. Looking from the front of plane each prop turns inward at the top of the prop arc. I thought this would help fight engine out asymetric thrust problem.
I normally tune each engine individually, slightly rich, with tach. I have a good handle on low to midrange operation. High speed seems to vary appreciably and inconsistently. I notice bubbles in fuel lines at varying times and rates-engine rpms sag and then smooth out again. Have tried several tank plumbing options-with and without pressure, separate fill line, etc. Any thoughts? Thanks for any help.

Hi Carl,

Its sounds to me like you have your model pretty well prepared generally .

some specs on the mossie:

The mosquito uses 2 standard Thunder Tiger .46's, both of which have had plenty of flights in other models. I knew that they were well run in and reliable when I installed them into the Mosquito.

I did'nt opt for retracts. It can be done apparently, but there is no provision made for installing retracts in the model. For a twin, the Mosquito is not that big a model at 71 inches WS, and I did'nt want the extra weight or headache of trying to install them. The scheme is based on a WW2 USAAF photo recon airplane.

Just as if they we sitting in an ordinary single, I tune each engine individually. Like yourself, I tune for the sightly rich side of peak revs etc, and so far I have had no problem at all with the engines.

The only concession I make to twin engine operation is to ensure both engines deliver full power at full throtte, and don't stop at idle. I don't otherwise make any attempt to match the revs between the engines.

there's only a couple of reason's I can quickly think of that will cause bubbles in the fuel line. An air leak in the tank or fuel line to the motor, or vibration. Both are fairly easy to fix.

A break or hole in the fuel line is fairly easy to spot. Check the integrity of the fuel tank by pressurising the tank. Blow into the (empty) fuel tank through the fuel line while closing off all other lines. Any air leaks in the tank will be audible.

The Mosquito also does'nt have separate fill lines or use a fuel filler valve. There is enough room for me to unplug the fuel line directly from each engine and refill the tank.

vibration can cause air bubbles in the fuel line...... make sure that the fuel tank is completely isolated from the airframe by foam rubber, and that the engines are firmly secured in their mountings.

Hope this is of some assistance to you.

Fuel bubbles. I am curious about the type of foam you are using and how the tanks are held in or against the foam. I believe that all my engine shutdowns in twins have been a result of fuel foaming.

I have a The Mosquito T111 that is almost complete. I do not have the plans either. I also would like to know if there are retracts available?

The Aerotech model company of the UK is no longer in existance I believe. I would have like to try out a few of their other models eg B-25 & P-38.

ESM do an ARF Mosquito of about the same scale and specs.

My own Aerotech Mossie now has approx 50+ flights on it and is going thru a renovation.

ive got 2 of these aerotech mossies.

1 fully built with retracts and the other is still a complete kit (sadly no plans) just build instructions.

would love a set of plans if someone out there has a copy to sell ££??

f104g

did you build the other Mosquito? .. they're quite straight forward to build, all pretty conventional build method. You could do it without a set of plans.

Maybe use the built one as a guide.

cabbie101

i had it built for me .

all the work i did was retracts and paint job am goin to try over the winter to build the second model
and see how i go

will post some pics of mossie soon
