Rob Caso's 37" Mosquito

Here are some pics of my Mosquito that I built a few yrs ago. It was an adjunct design from my original which was a much simpler model with spd 400 cans, no retrax, rudder or flaps. In the original, I was pumping 11.1v through cans rated at 7.4v and, more than once, the model came home with "one turning and one burning". The motors were so out of balance that, one time, the motor parted company from the nacelle and was just hanging by its wires. No problem when greasing it in. Not once did it exhibit any bad spin or other tendencies and I felt that if it was that good I could do a "full out" model that you see here.

Here are the specs:

Wow looks great - the retracts are a triumph. Do you have any more detailed photos/drawings of the retracts and how the pneumatic actuator operates them?

And here it is....!

The hard part is doing all the bushings but it is a relatively simple assembly...

The PDF has photos of the mock up and below is the finished LG in the plane that I fly....Since then the elec retrx have come out and I would serious consider finding an actuator to take the place of the air cyl. This would be lighter, simpler and less - I mean "no" - plumbing. I found one but lost the link, if anybody finds it let me know

Build log

Jason, a number of years ago, I had done a step by step build log for this model with photos and text but the PDF file is too huge to post at almost 6 meg.

What you really should do is to order the glass nacelles from me, even if you don't do the retracts and then I can send the fuse parts along. These are alot easier than building ea nacelle out of wood and they look nicer.
