OK ..... in the shed and ....... another photo fest .... so if you don't want to go through it ..... switch off now.

 

Not the best of photo's as I have not physically unbagged everything but that will be put right on the build. Just trying to preserve things a bit.

 

so ....   the box ....

 

P1130105.thumb.JPG.180411a5403cd4d05104b3a4bfb9335f.JPG

 

and the inner carton ....

and a second wing spar with a go get em wire for fishing cables through the fuselage etc.

 

I seemed to have lost some other photo's of the fuselage showing the battery compartment which I did take but for some reason ..... they have'nt come across.

 

If i can find them ..... I'll post them up ..... The box is unfortunately taped back up and it aint worth opening it up just for that. Trust me though ..... the space is huge and will easily take the two required 4S batteries and a reciever.

 

hope the above is of some interest.

Hi Chris,

 

I forgot . :classic_sad: it will be the weekend before I get the chance to open it up again but I will do it and post up the details. If you can keep an eye open I would appreciate it.

 

thank you kind Sir

I'll calc the P38 and OV10 as it will be interesting to compare Flightline models. I know the OV10 is heavier (55 inch) compared with the P38 (63 inch), but the twist is the OV10 has a plank of a wing and the wing loading is less than the P38. 🙂

By the way Chris .... I'm sure it's only a dozen screws to assemble. A bit of wiring to pull through some routes but they give you a fish wire for that.

 

Connections are easy to make and pretty well detailed. 4 x props to install and again pretty straight forward. The inboard and outboard motors are such that you can't connect them up incorrectly supposedly. 

 

I think the most time consuming parts of the build will be the glazing, miscellaneous small fittings and setting up with your transmitter.

 

I'll need to check for the decal sheet as there are definitely not all fitted out of the box. I'm sure there are further waterslidesto be fitted.

 

They do seem to be quality kits but without having assembled or flown any yet ..... can't honestly vouch for that.

 

So far so good though and excellent service from both Motion RC and Fedex to date ..... no complaints.

.

Cheers

I'll be opening up the carton again at some point this weekend for the measurements for Chris so if anybody wants a specific shot of any particular detail ........ shout out now as once its shut ....... the horse has bolted.

 

Cheers

That's quite an impressive plane.

Uncovered servos in a foam depression are simple to do and if flush with the surface have no aerodynamic penalty. You could always use a bit of filler and paint to disguise them.

Probably worth getting some matching "touch up" paint anyway once you get round to flying it. 😉

Hi Simon,

 

I'll take a look at it again nearer the build time and see what can be done. From memory and a quick look back at the images, I think they protrude beyond the surface slightly. Probably why the manufacturer has left them how they are. ..... pity.

Hi Chris ( walby ) 

 

Not forgotten about the wing measurements. It will be Saturday / Sunday before I get the chance. I have a couple of things I need to do to get myself prepared for this Saturday's flying ( hopefully ).

 

Not enough hours in the day sometimes.

I have one of these since they first came out.

The only issue with it is there is less than 1 inch of ground clearance between the props and the ground as the landing gear is very short, so you have to try and land it nearly level with a very slight nose up attitude to keep the props clear.

the other thing is if you come in fast and hit the ground the outer part of the wings flex and smack the outboard props into the ground and sometimes ripping the motors out.

if you land gently then this is not an issue.

i recommend you either buy in loads of spare props or change to the master airscrews which are stronger and do not break easily.

Plenty of discussions on this on the internet.

Otherwise it is a very easy , almost boring plane to fly with no vices. Fly it nice and slow and it is is enjoyable.

Many thanks for that Djay. 

 

I must admit, the ground clearance was a worry when I looked at it and I think you have confirmed my thoughts. A nice easy boring flight with no gotchas was exactly what I was after.

 

There are plenty other models at Motion RC to get the heart pumping when I'm ready ...... :classic_laugh:

 

Thanks for the input.

OK ..... I hit the shed and have a couple of wing measurement ..... I hope they are of use .....

 

The length of the wing from tip to root is 95 cm

 

P1130144.thumb.JPG.35c27b6c129924970df6fc46eaaee3c2.JPG

 

The width of the wing at the root end is 28 cm .....

 

P1130146.thumb.JPG.8ad54d3b71e73c504a46cdde78b1e584.JPG

 

and an odd job measurement which will probably be of no consequence is a measurement at the tip ( almost ) ....

 

P1130145.thumb.JPG.efc7476ce521d480eaba7aeb6b21a499.JPG

 

just at the edge of the aileron and is roughly 12cm ..... just to show how much the wing width tails off over its length as it may just help in calculating a rough wing area ..... with a little but of " eyeball geometry ".

 

Hope this is of use Chris ( walby )

 

cheers

Still forgot to check if there were any further decals included when I had the box open ...... not going back in now ..... Doh....

 

I'm sure there will be.

Hi DJay.

 

two sets of each prop type arrived today ..... I dare say there will be many more but that can wait. I've covered my first landing ..... probably the maiden. 😄 so your advice has sunk in.

 

cheers

Apologies for the delay, been flying, fixing and trying to sort out the odd model for a show. Anyway the unchecked results are in!

image.png.6baefe66d4caabbb9199a5b69548b465.png

 

 

From the web (not validated),

For normal sized models, around 60 inches (1.52m ) wingspan, a glider or foamie will have a wing loading of around 12–16 ounces per square foot. A sport model or aerobatic plane will be around 16–25 ounces per square foot, and warbirds will go up to 32 ounces per square foot. Jets will be higher, 

 

I asked a question on the forum about "your next model post A" and warbirds (as they generally have higher wing loading) to see what the general consensus was. So back to the point I am trying to make! The B24 is bigger and has a slightly higher wing loading but nothing like my Big Tigercat! and I suspect it will fly like a big trainer as long as you don't try doing non scale things or stick bashing. Now here's the area of concern IMHO and that is workload and pressure (not making it fit a bin liner). The B24 has features that will help or hinder you like  retracting UC, good news they reduce drag once away, but can slow the model up and possibly make it pitch change between up or down, hence increases your workload. Flaps set for take off (I use it for landing as well) means you can fly slower (IMHO the stall is a bit more aggressive all be it at a slower airspeed), but adds drag which you may not be used to. My BH Mossie with UC down and flaps at take off needs very nearly 50% throttle just to maintain flight so I really have to watch its airspeed when flying/landing in that configuration!

 

You could to choose (when the time comes) to fly with the UC down all the time and no flap and at least you will know how it flies when it comes to landing, but it will come in faster and look pants flying around with the gear down all the time. Or get practice and more practice on the sim with a suitable model (retracting UC and flaps) so you can fly it on the sim, take off then UC up, flaps up, circuit and then UC down and flaps landing. Don't rush it in one circuit, but take say three circuits. Landing should start with UC down as the model passes in front of you (check all UC is down) then landing circuit, flaps and land. i would say that you need to be very proficient as to where the switches are by feel only. Practice without flap and get a feel for the difference in air speed and practice plan B, should say UC fail to come down (not landing on the tarmac but on the longer grass say). You can also practice with your high wing trainer with deploying a lot of flap and getting use to what you need to do, my Kingfisher does a massive pitch up almost full stick down to stop it looping (at above 75% THR). I know its going to do it so I am ready for it. Its great for STOL take offs as it just leaps off the ground...but I have to be ready for it!

 

As mentioned before, leave the model standard as it won't take much to increase the wing loading to where forgiveness is not granted or given.

 

If you have the aileron and flap sizes for the B25 I'll calculate that as well.

Thanks Chris,

 

Just picked up on this. I won't be able to get more sizes right now as it's packed away as I demolish my shed whilst awaiting delivery of the new one but will revisit this again as soon as I get the chance.

NP Toto, enjoy your holiday and I am following the shed building as I have plans as well. Mine will be mostly for storage and a large useable space for spray painting as it will be much easier to sheet off than the garage with all the tools and models.

 

On the top of my list is the Big Tigercat, only had four flights (one of those was at the LMA event with a Bearcat, Hellcat & P47) and despite its weight and size its pleasant to fly and needs to be held off touchdown to bleed the speed of. Perhaps the wing loading is less important than taking liberties or doing something wrong. The Tigercat is currently massive workload, but very rewarding when it stops rolling!

Hi Toto.

 

Thats good news on the maiden.

I did originally order in a set of sprung loaded oleo retracts sold as an upgrade, but when I got them realized the oleo would compress even more on the landing and it would give zero ground clearance, so kept the originals.

I ordered a set of 'Black cat' decals for mine from Callie Graphics.

The plane is a bit battered but still flying.

Thanks chaps.

 

Chris ..... I will enjoy the holiday .... can't come quick enough.

 

I've went a bit easy on this post so far as its all pretty boring stages of getting rid of the old but I will be sure to post up more of the stage by stage installation of the new shed. That will include the new shed itself as it arrives and the elements that I add .... including ventilation, insulation and internal lining.

 

The actual partitioning of space and fitting out with work spaces and electrics will be covered as well.

 

Maybe not to everyone's tastes / interests but will suit some. Hopefully folks will be able to take something from it ....... good or bad. Best practice or mistakes ..... its all learning.

 

Look forward to having you aboard for the rest of the journey

 

Toto
