Tomboy 36 for RC, Build

[cloudburstz]

Getting on with it finally. Making both formers forward frim ply and the 049 is on a quick test bed.
I visited a local control line club, really helpful, will get some fuel on Sunday and start running in the motor.
Now to find tubing small enough to fill the fuel bowl through that small hole

Dear,
why not take a seringe to fill the little tank? I have a .40 Classic and fill the tank sucessfully with a seringe. The tiny hole is so no obstacle any more. You can use the seringe also for priming the engine through the side ports for easy starting, but only two to three drops, otherwise you flood it.
You have given me a great stimulus in building also a Tomboy with a .049 Redfin Diesel (and maybe another electric?), putting my own project pride apart, modestly recognizing this great design! There are Tomboys all around the world, but we have none in Rio and so mine shall be the first hopefully of many to come.

Greentings,
Kurt

Good to see you back on this CB. If you prime the motor via the exhaust ports ensure that the piston is covering the ports and only use a small amount. It's too easy to over prime and possibly cause a hydraulic lock.
Also only suck the fuel up to the carby and don't suck extra fuel into the motor for similar reasons.

Hi John , Kurt
Working up in Singapore but its nearly finished. I have run the motor several times now and its easy to start. Usually a small suck through carby with a finger over it is enough.
I got some mini servos delivered and hope to complete it next time home. Going to use the remaining esaki Tissue I have , just figuring out about fuel proofing. On others models I have used Eze/dope but they didny have an engine. I also have some conventional acetate type dope unused. Anyway, its looking good, want to finish it now and start something else. Cheers B

Off to the airport shortly but good news, Suns out , light breeze, up to the school oval early.
All went well but I've noticed a few things.

Engine started in reverse a couple of times which I'd not had before.
First flight only had a small amount of fuel about a 10 sec run. level flight & nice landing - Success! ( insert happy face here )

Second flight used a full tank nearly , trim was good , just a couple of notches of down trim. Trundles around in a stately slow manner, the diesel chugging away. I think I've not got it quite as tuned up as it could be yet, but its adequate. Nice glide down from height and soft landing and roll out.

Final flight saw the engine quit a fair way upwind , quickly turned and came back downwind , did a steep 180 turn in front of me and dropped it in.

All in all , pretty happy. I have big throws on the rudder and elevator but I'm not heavy handed so the radio is on full rate still and its very controllable .
CG is just a mm or 2 behind the main spar and the glide was nice for landing.

Spring I made for the compression screw is not quite tight enough , the screw would back off slightly from the best position, can fix when I get back home in a month.

All in all very satisfying , looking forward to some still warm nights in October.
My photographer kids all asleep when I left so pictures next time.

Good on you CB. That's something to look forward after this trip.
