DeHavilland Mosquito 81
 
Hello to all I am new to RC UNIVERSE and still trying to figure it all out but here goes nothing I have started to build a Brian Taylor DeHavilland Mosquito. I started with the stab. and have finished one half of the fuse. then I made the rudder and virt fin and now have started on the second half of the fuse. this will be a nighter fighter verson with full armerment and I plan to power it with 4-strokes the OS FS-62v they are a bit larger than the engines that Brian Taylor used but I will be making some mods to my build, his was 13lbs 10oz I'am trying to keep mine under 16lbs.

Hey Splinter, Welcome and post some pics. The mosquito is in my top 5 favorite twins list.

Ditto on the welcome aboard.

Just watched the movie '633 Squadron' again the other night. It has some great footage of the Mosquito. Love the plane and am looking forward to seeing your model take form.

I only ever post one at a time. This works every time for me. It takes longer, but much less aggravation. If one still won't post, run them through 'Photo Razor' and down size them a bit.

I use Zoombrowzer. After they are resized they load up pretty quickly. It seems RCU is a little faster here lately also.

Welcome Splinter,
That remind me that I have one of those somewhere, you might motivate me to finish it! I recall that I got a scale gear from Robart perhaps you can still get them, they do look nice.
Make sure you reinforce the center wing section and install a stronger spar, wing failure has been a weakness for this model. Good luck on the built I am looking for to see your progress.

Welcome Splinter,
I have just started one of these on the building board. As yet I have not started gluing bits while I finish off a TF Spit.

The Unitracts retracts I have received are just great and should look and work a treat.

Having a couple of Saito 72's sitting idle I was planning to use means I had better take care with the mentioned wing strength weakness.

Looking forward to seeing some pics of your build.

thanks to all for the kind welcome I have a bunch of photos I would like to show but I will see what I can do if you click on my gallery there are some photos there I thought I was going to write a blog but moved to this site I think this is a better place to show this build. now if I can get some photos to up load we'll be in business so I will try again

well I see how to do it now but wow it takes some time lets try some more this is some of the mosquito with the armament I want to put on not all the same bird I still havent been able to find a sqn. that has all of the armament that I want and the photos that I have you can't see any of the call letters OK lets try these pics.

i have been told these rc planes dont fly well, but i cant belive it....its from taylor plans they always fly nice

UUUaaa ho, he figured it out, looks like we are in for some great build pictures now.:D :D:D:D

Very exciting. Thank you.

let me see if I can go through and get the ones that I didn't show. I'm use to telling about each pic. with a caption but I don;t see where you can do that so if you have any questions just ask and I can take more pics so you can see what is going on. I had heard that they were haveing planes crashing on there first flight and while I have been building this there are things I saw right off that had to change. I am planing on making the landingear myself along with the cowlings and canopy. the wing is in one pice by the way Brian builds it but I will be changing that some how I haven't quite got that one figured out yet but that is a ways a way I will most likely use carbon fiber tubes some how to make that change. OK some more pics.

well I have done some more work on the second half of the fuse I don't konw if you can see the diffarance in mine but the 1/4" part at the wing socket extends ferther out to the ply and I mortis and tendond the ribs in place I also used 3/16" light ply in stead of 1/8" ply. O also will be adding stiffeners were the two halfs meet at the wing scoket I will show some pics when I do this this area needs to be beefed up considerably in my opinon so I will be doing some more and again I will take pics to show what I have done - here is where I'm at now.

Actually, the BT Mosquito is a very good flyer. I know 2 people who have built these, one with OS 46 2 strokes, the other with Laser 4 strokes.

However, the take off can be a real handful. High ground angle, tiny rudder not in the propwash, taildragger.
Engine pick up from idle must match very closely, you have to advance the throttles slowly & carefully & you have to keep the tailwheel on the ground as long as
possible. If you have a nice long smooth strip which can give you the time & space to do achieve this you will be fine. I think I have a cockpit video of a full size
Mosquito taking off & the pilot is VERY busy with the rudder & throttles.

Single engine flight is difficult with the Mosquito as well, if you have height & speed up your sleeve reduced thrust on the live engine will extend the glide, if low &
slow & you are quick enough to realize you have lost an engine your only choice is cut throttles & good luck!

Good luck with it, it's a real thouroghbred but it will break your heart if things go wrong. - John.

I kept working all day today and got a good bit behind me check it out.

While not quite the same size and not a kit, Ive got a 73" CMP Mossie overpowered with two .91 saitos. This BT mossie will be interesting to watch the build.

Splinter.....you may wabnt to consider using a twinsync on the motors.

splinterz25 01-14-2012 03:53 PM

RE: DeHavilland Mosquito 81
 
kahloq what is a twinsync? do you have a link? or is this just like a muffler bering and or a sky hook?

On the full scale, the pilots steered with the brakes on takeoff.

A twinsync is an engine syncronizer. Its goal is to keep both motors within 200rpms of eachother throughout the throttle range. Additionally, if one motor quits, it makes the other motor go to idle automatically to prevent the plane from entering a death spiral spin from asymetric thrust when one engine dies. It does this by monitoring a sensor that is installed to count a magnets rpm's that is imbedded in the prop shaft....thus how kit determines each motor's rpm's.

These are the magnets you imbed in the drive shafts(basically in the prop driver):

I used the longer cylinder type on my saito 170 radials mounted on an ESM B-25.
