FRCFOAMIES DE HAVILLAND MOSQUITO

[dehager]

I ordered the plans from FRCFoamies this past week and I am in the process of converting the plans to gcode for my needle cutter. If anyone is currently building the Mosquito I would like to hear about your motor, prop and ESC decision. There is not much activity on the RCPowers forum so hopefully someone here can add some details on their build or a similar twin engine build. So, looking at the current availability of the motors today these are the three that appear to fit the bill for a 2S 2200mAh battery setup with 8 inch 3 bladed propeller. I may do a 3S battery but I would prefer to keep it light and scale like in performance.

I may consider the FT Radial 2212 but the shaft is too short to add a spinner on the one that I have. I am not sure if they have changed the design recently.

Hi, tho i haven't built that particular aircraft. I can tell you that any of them would be a good fit. And they would all handle 3s very well tho the tree blade at full throttle may push the 1400kv one a bit. Your best bet is probably the 1200kv emax.

I built a twin cargo plane similar in size and with small crappy racerstar 2208 1400kv and it was perfectly adequate. I think probably the best bet os seeing what you currently have in terms of lipos and fit the motor to use those

I've really liked the 1808's I've been running lately... I think they'd be good on that build.

What foam board are they designed for? I like the look of some of the plans

They're made for 6mm depron. Foamboard works well, I've built a few of there's. My only reservation is that depron comes in a longer sheet so for instance i had to make the tail control surface on a separate piece and tape it on.


I'll make another FRC plane this year. Revisiting the alpha jet mk2 which I scaled down. Making a proper full size version this year.



Here is my frc su 37. Foamboard and tape. Amazing airplane
