Dynamics Unlimited Tiger Moth Build
this was my first real attempt at building a micro flight kit using the RFFS system. i would first like to say that Dynamics Unlimited is a very very good company to work with. they helped me with every question i had and even replaced a damaged actuator for no charge or shipping. they have a online chat on their website that you can log on to and ask questions if need be. http://www.slowfly.com/index.chtml
all instructions are in color and pretty easy to follow.

the balsa kit comes in sheets and all the parts were laser cut. very very good quality but be carfull.......the parts are fragile.

the wings went together first

then the fuselage........i used the old windex trick to bend the balsa without it splitting.

attach the bottom wing

and the rest of the control surfaces.

the hardest part of the build was figuring out how to use the actuators. i ended up mounting them on the tail and using very small/light pushrods to connect them to the elevator and rudder. you have to be very gental with these. they will break if you try to force something into or arround them.

i think this next step was my undoing..........i gave my TM a coat of paint using my airbrush. i tried to keep it as light as possible but when i looked at how much paint i really used i had a feeling it was too much.

i made the landing gear out of very light weight music wire and a few pieces of metal tape.

you can see how the KP00 motor fits very well in the cowl area

the RFFS Rx fit very well in the fuse with a piece of double sided tape.

everything installed. notice the actuator mounted just below the elevator.

*****Flight Report*****
well........i was excited to get it up in the air and when the time came it was a bit to windy out but i tried anyway. i launched it and it flew upside down into the grass and broke the top wing off. i CA-ed it on again and waited till the wind was calm and i still could not get it to fly. however...........i do believe it is my fault. i simply built it to heavy. i was way to sloppy with glue and i think the paint added to much weight. i know from building other electric models that every little bit of added weight decreses preformance and when the target weight is only 1oz..........going over even a little is like putting a brick on top of it. i have already ordered a new plane from DU and i have learned my lesson with this kit. i will post a new review with the new kit soon.

RE: Dynamics Unlimited Tiger Moth Build
Nice review
On the flying part.
One thing that I found out real fast is to launch at 3/4 throttle. Full throttle would flip it(or almost any short coupled micro) to the left instantly.
I have the same model, or least the same set of wings/tail. The fuse was killed by a youngsters heavy hand. So I made and other from a Arbor Freight "Lightning". I found the KP00 with the 2.75 gears and a U80 prop to be a little weak in the thrust area. I tried the KP00 4.75/ blue prop and it made a lot of difference. One thing to note is that the 4.75 setup is a little harder to launch do to the extra torque. But once it's flying its great, with a cruise a %50 throttle. Just launch at lower thrust and once things are straighten out and flying (i.e. not upside down and going in) give it the juice and your good.[sm=thumbup.gif]
