I've a Mosquito Pr16 81" from Brian taylor. It is recomended to powr it with two .40 to .70 four stroke motors. I have two .40 cu in two strokes motor. Can I power the plane with them?.
Thanks you very much

I have built and flown three Taylor 81 inch Mossies....My current one is powered with 2 OS 70 Surpass engines. We';re I to do a fourth, I would power it with 2 OS 90 Surpass engines.

A pair of 40 2-strokes will work fine. (The lighter the plane, the better.)

I would definitely recommend staying away from 2 strokes in a twin. That's the reason I lost my first Mossie...engine flamed out and the plane rolled right over. The 81 inch Taylor Mossie will build out between 18 and 20 pounds. No way will 2 stroke 40's fly the plane...as I said, I would put Surpass 90's into it and really enjoy flying the plane like the real one flew!. My 70 Surpass's fly the plane fine in straight and level but into the vertical and the speed bleeds real fast. Couple that with the planform of the Mossie wing and the top of a loop will see the wing snap over and you're into a two rotation spin before you know what has happened...I know, I did it! Go with 90's!

I can't agree with the comment to "stay away from two strokes for reliability reasons". I have four twins, all flying with two stokes, and have not had reliability problems.
I have a 15 lb. Westland Whirlwind with two OS 46's and it flys well. To define "well", I mean 100 ft. Take offs with a 20 degree climb out and, with a high speed entry, loops from level flight. I do not mean unlimited vertical or anything approaching that.

Congratulations on your success rate. Clearly, they work for you but I have found them tough to synchronize and tougher to get identical throttle response. I prefer the four strokes when flying a twin. Just my opinion, though.

I just got a Brian Taylor 81 Mosquito Short Kit off of ebay for $160.00. Since you seem to be the only real experienced person on the posts with a Brian Taylor Mosquito I feel your information is much more valuable. I just wanted to know what you did as for retracts and other building ideas. I appreciate your opinion on engine size and I will be going with 90s also. Trying to do a scale loop takes a lot of power. Any other ideas or input would be greatly appreciated. I am excited about the mossie and this will be my third twin. My first one is a Wing Manufacturing P-38 74 inch wingspan with 2 OS 46 FX enignes which is the largest engines they suggest and it barely does a loop at 12 pounds. My second is a Jack Stafford Comanche Twin 76 inch wingspan with 2 Fox .40s and very oddly it does a loop easily at 11 pounds. Like you say I think it depends on the plane. I still have both planes but have lost one engine on the Comanche Twin 5 times, once at the top of a loop, Wooo Hooo. I kill the throttle and make the best landing I can somewhere. Trying to fly on one engine with that plane becomes ugly very fast. Nothing more than some bent landing gear on the crash landings so far.

Well thank you for your comments. I do appreciate it and I guess building and flying three of the Brian Taylor 81 inch Mossies count for something. I still have the third one flying though very rarely since she's an old bird that is breaking more easily these days. I looked at the date of this post and realized alot has changed in the past 6 years. Were I to build a fourth ( and I like it so much that I might) I would build it for electric power. There are several great power options that would fly this plane really well and eliminate any chance of an engine out. At 20 pounds ( which would be a heavy airframe for an epower system) you would want 800 to 1000 watts per engine. This is easily doable and would allow you to run scale 3-bladed props. As for retracts, I use firewall mount Spring-Aire retracts and cut the landing gear to a one inch stub and machined a "U-shaped double strut that attached to the stub. I didn't make the tail wheel retractable. I reinforced the area between the wing and the cockpit cutout with several spruce (but you could use carbon fiber) longerons since the nose has to hold a fair amount of balance weight and alot of stress is put onto that relatively small area. The Mossie has a long tail moment so try to make the tail as light as possible. Building it for e power should allow you to do it . There are a couple of good threads on building the Taylor Mossie for Epower on RC Scalebuilder Electric Scale forum as well as RC Universe. Good Luck

RE: Brian Taylor mosquito
 

I am thinking about the retracts for this beast now. I am going with two .91 4 strokes. i have to have the smoke, noise, and fury of an engine to have the effect. I was wondering if the robart gear for the DC-3 would work for the Mosquito? Has anyone tried this? And Lastly where is a place to get a set of retracts for the Mosquito?

RE: Brian Taylor mosquito
 

I often thought about re-engineing my Mossie with a couple of OS 91 Surpasses....couple reasons I never did...first, it would have required relocating the firewalls which would have been alot of work and second, I had heard that they were not as reliable as the 70 Surpasses (which I had and never had any problems). I'm sure your's will be just fine. Can't help you with the gear as this was always the area that was the most challenging for me. ON a sad note, I lost my Mossie this past weekend...combination of a slow approach and an old airframe put one too many jolts through it and both the back broke as well as the main wing spar. So much fire wood sitting in the middle of the garage....but as I said, I will build a new one with E-power...keep up the good work with yours...

RE: Brian Taylor mosquito
 

I have a set of Robarts made for the Taylor Mosquito but I think they discontinued them. You might touch base with them and see if they could help.

RE: Brian Taylor mosquito
 

thanks for the info. i will contact Robart. At least they ought to be able to compare the two and see if they are compatable.

RE: Brian Taylor mosquito
 

Hi!
Brian Taylor himself suggest .40-.50 four stroke engines!

RE: Brian Taylor mosquito
 

make sure you are talking about the right sized gear...Taylor's original drawings are for a smaller Mosquito...70 inch wingspan or something like that...most who are building the Taylor Mossie are building the blown size (80 inch wingspan) which require the larger gear (and bigger motors)

RE: Brian Taylor mosquito
 

He is right. make sure we are talking about the same plane.

Here is a link to Bob Holman plans showing the 71 and 81 inch Brian Taylor Mosquito.

I emailed Bob Holman and he has sold the Brian Taylor line to Traplet Publications: www.traplet.com

RE: Brian Taylor mosquito
 

LA7flier, my Mossy is the 80" model and these gear were made for it. I am quite sure they are the right size as they fit just fine.

RE: Brian Taylor mosquito
 

that's good...I never knew Robart made a set for the 80 inch version of the Taylor Mosquito. My first attempt at gear was built around a couple of linear drive shafts running the rear struts up and down which lowered and raised the main struts....never could work out the bugs and went to a Spring Aire firewall mount unit with a home made double strut assembly

RE: Brian Taylor mosquito
 

I found them listed on the Robart site as discontinued and the link to the dimensional drawing didn't work. I emailed them asking for some more information and maybe the drawing. If the DC 3 retracts would work or the gear could be fabricated using Robart parts that would be sweet.

RE: Brian Taylor mosquito
 

I noticed someone else posted this on another thread here. But it looks like they do custom work. Might be $$$$$$$$

unitracts from UK made set
I believe that they are on plan as well

RE: Brian Taylor mosquito
 

My whirlwind whirlwind has the same type of dual strut gear as the Mosquito as you can see in the three view linked below.
On my model, I used a single, side strut the same as most gear but made a "dummy" strut out of tube and balsa for the other side.
When you look at it, you can't tell the difference.
You also might want to look at the Fults struts as a possible answer. http://www.fultstooling.com/

Also has anyone found a cockpit kit for these 81 inch mossies or at least some stuff to help fabricate one?

The Mosquito is a great plane, I saw Kermit Weeks fly his at Oshkosh a few years ago and it was something to behold.

RE: Brian Taylor mosquito
 

Wish I could of seen that. Are there any Mossies flying anymore?

Here is a bunch of old boys in Scotland that flew one in 84

RE: Brian Taylor mosquito
 

Weeks plane is in the Eaa museum now and there are others undergoing restoration but I don't believe that any are currently flying.

RE: Brian Taylor mosquito
 

A buddy and I have started one of these. I just don't see how this thing is going to weigh 20 lbs. when completed!
I have a pair of 70's for it and hoped to use them.......but at less than 20#.
Does it take a ton of nose weight?

Jim

RE: Brian Taylor mosquito
 

Hi!
20lbs..thats around 9,5-10kg! Way ,way too much for a 81" (206cm) Mosquito.
Brian Taylor recommends himself .40-.50 four strokes in the 81" version.

One modeler over here in Sweden built and flew the smaller 71" Mossie in a scale competition in Canada ("stand off scale" ) a number of years ago and he had his powered by .25 two stroke engines.

Personally I would estimate a ready to fly weight of around 5-6,5 kg ( 9-13lbs) for the 81" Mosquito powered by OS .48 -OS .56 engines

RE: Brian Taylor mosquito
 

I got some drawings from Robart. One is the parts drawing from the discontinued Brian Taylor Mosquito. The other two are the dimensional and parts drawings for the DC3. We might compare them and see if they will work for the Mosquito. The ones from http://www.unitracts.co.uk/ are 250 pounds sterling for the mechanical complete set and 320 pounds sterling for the pneumatic complete set. When I convert into US dollars it looks very painful. I may email Robart again and see if they still have the dimesnional drawing also. The Robart ones that are discontinued look very nice. They have shock absorbing struts and look very well made. I will try and find out how many of the parts are avaliable. I will also see if maybe they will stamp out a limited run if enough of us are interested. Let you know what I find out.

I found these Air retracts from Century Jet retracts $350.00: http://centuryjet.com/product_info.php/products_id/298

POST MORE PICURES OF YOUR BUILD PLEASE

RE: Brian Taylor mosquito
 

GOOD LUCK!!!!All three of mine that I built and flew (all 81 inch wings) weighed at least 20 pounds....lots of nose weight will be needed. I glassed the plane and :Dused functional retracts (probably a pound a piece), functional flaps and a non-retractable tailwheel. The Mosquito has a very long tail moment and is probably over-designed. As to the flight characteristics....the plane flies fine at 20 plus pounds as long as the power is there. If people can build it at half that weight...great!....they are far better builders than I.....:D

RE: Brian Taylor mosquito
 

Never saw any Mosquitos on the link above. It is a total waste of time. Should have just said you had some airplane stuff to show. Doesn't really belong here. It may have confused him when the one guy showed photos of a DC 3. So we are all on the same field here is the Mosquito from the USAF Museum.

RE: Brian Taylor mosquito
 

Robart made a custom set of retracts for the 81" Mossie, excellent quality. Cost was around $400.00.

Cheers,

RE: Brian Taylor mosquito
 

The Unitracts ones are the best units for the 81" Mossie in current production, and follow the scale geometry. I do appreciate though that when converted to USD it comes to more than the average person would like to pay... That said since the GBP has nose dived this is a good time to get them if you live outside the UK.

Still, if you want the wheel down in the correct position and up in the correct position then the scale geometry is the only way to go. The retracts are on the plan though too and can be built using hand tools ;)

I'm just about finished building the tailwheel unit shown on the plans for mine and will build the mains when my metal work area is free (full of bits for my fullsize aeroplane at the moment).

Mine will be electric powered as it's the only way to get reliability and scale sized 3 bladers on. It also means less dead weight in fuel proofing and no CofG shift as fuel burns off. I never did agree with anyone telling me single cylinder IC engines sounded anything like a fullsize V12 anyway so I've never looked back since my first electric model a year ago. :D Obviously there are no problems with synchronising a twin either!:D

RE: Brian Taylor mosquito
 

Thanks for the info, maybe I will look into building my own. The Office manager's brother gave me a little Austrian made Unimat lathe so now I have a machine at home.

By the way the support Robart Manufacturing has given me has definately unsurpassed. They have mailed me drawings and any information they can. I have never seen support like this to support a customer. GOOD JOB

Can anybody tell me where a pair of spinners can be had for the 81 inch wing Mossie? I thought Gene Barton used to provide them but am not sure anymore...

RE: Brian Taylor mosquito
 

Here's how our build is progressing. The fuse has been glassed and some primer applied. The other parts are getting close to glassed, but the nacelles are being built first. Its coming out pretty light weight so far. Its challenging, but rewarding building.
I still plan to use 2 OS 70 4-strokers.
Not sure what gear to use yet......
