Platt Dora -Purchase to bash

well picked this up for $130 , now i will bash it to more scale .
Interior , retracts , flaps ect .
Redoing the pilot and so much more .Expected to be at 9 to 10 lbs .
Was going to use a Monster 110 because i have one but I think its too much motor, dont know , dont know enought on epower yet , just a warbird guy .

So far picking up Wingspan Retracts 85 degree, spinner and will scratch built the interior. Will also add Williams brother wheels "thin"

I started this thread as the Bash thread , anyone have advice on power , I appreciated the past comments on me wanting to use my 110 , I was just trying to save money so if that is not an option and a 60 or 90 is in order then so be it .
expected at 10 poounds the 110 would be 200 watts per pound , a littel over kill plus the battery weight .
I guess a 60 thru 90 is in order and all the budget guys are out of stock so potentally a eflight 90 for $139 will be ordered unless i find something elese

I have a NIB Platt 190D9 that is my next plane to build, actually I have 2 NIB but thats another story

My plan is a Power 90 with 8 or 9S.

I have a hanger 9 P-51 on 8S that flies great, and a TF Sea Fury with a 110 on 9S in it.

I went with a 5 bladed prop on the Sea fury so I needed the 110, the 110 has more than enough power for that plane, in fact too much power on take off that can cause problems. But the plane needed a ton of weight added to the nose so the 110 is not an issue.

I'll start with the Power 90 on 8S and prop for about 150 watts per lb or max amps which ever comes first.

Thanks Ken , so your suggesting the power 90 , on an 8 or 9 s .
I also have a Seafury that can make a good home for the 110 , so that will be my plan.
Just an FYI , I am looking at Wingspan retract 85 degree , still evaluting them , cant seem to find review.
Thanks agian for posting a reply

Since this is a 60 size-ish plane.....a 110 might be a tad overkill....HOWEVER.....if your planning on running a power 90 and still going 8s, why bother as the 110 on 8s is a beast.

I have the graupner fw-190 dora9 that is slightly larger at 68.5" and weighs 10 pounds. Im running a monster power 110 in it on 8s 5000 spinning a 15x13 2 blade prop. This is one of my fav planes to fly.
I also do NOT need to fly full throttle and usually run slightly over half unless doing a high speed low pass for giggles. As such..I can generally get about 8 mins flight time with reserve.
The power 90 is going to consume more amps since the kv is higher and cant spin quite as big and/or as high a pitch. If your looking for speed....cant beat a 15x13(hobbyking)....or a 16x14 APC or similar prop with this setup.

Id say just use the motor on hand with an adjustable mount. If, after you fly it using the monster 110 you dont like it for whatever reason, you can then swap out the motor and only real thing you'd need to adjust is the length of the motor mount.

Most of my heavier 71-73" size planes that are electric are also running 110 size motors. My ESM 109E has an e-flite 110 with an 20x10 turnigy wood prop and my esm p-51B has a Tacon 110 size motor with an 18x12 turnigy wood prop. The CMP ME-109F I have has an e-flite power 160 on 10s spinning an 18x12 and its not really much faster then the esm 109 with the 8s setup.

Friend of mine has the Pica 190D9 using a 20cc gas motor and it flies really nice as well.

If your worried about prop clearance, Im sure you can get something like a 3 blade 16x12 somewhere or use a 15.75x13 3 blade from APC. Ive used that prop before on my CMP 109. Once in the air it flies well, but it takes longer to get off the ground then when using the 18x12 turnigy wood 2blade.

Thanks Kahlog, that will save me some cash and I can focus on the battery set up .
I also have a uncut spinner on the way , so I have options on a three blade with the uncut and two blade with the spinner that I have on hand. Would happen to know what prop adapter you used for the Monster 110 ?
Now onto batterys and combinations

If I remember correctly, I turned the motor around and used an e-flite 110-160 adapter on the motor shaft. Its the one that uses grub screws. The e-flite adapters of this size are already tapped for a bolt thru the middle type spinner.

For batteries....two 4s 5000 nanotech or turnigy are what I normally use.

Of your current battery options...using your monster 110...you can do:
1) 8s 3300...ie 2x 4s 3300. Flight time...4-5 mins depending on throttle managment and prop selection.

2) 8s 4400...ie 2x 4s 2200 in series x 2, and then again set in parallel with 1st set...flight time 5-6mins

Without buying new batteries, you'd have to get a power 46, turnigy/monster equivalent to use your 5s 5000's singly
OR
Get a power 160 equivalent and run 10s. Weight wise, thatd be a bit much for a 64" ish size plane.
A 5s might be a bit low for a 64" ish size plane, however, ive got a 59" Corsair running a power 46 on 5s spinning a 14x10 and its decent fast.

Guess it depends on what you wanna do. You can test how your plane flies with your current motor and the 4s 3300 batts and see if you like the power output and speed in the air. if so, then you can upgrade and get some bigger 4s 5000 batteries later on....or even get more of the same batteries and use 4 of them to get 8s 6600 all the while having more batteries to use in whatever plane your using 4s 3300 size in already.

You could also use your monster power 110 on 6s. Ive done that in a hangar 9 DVII biplane turning an 18x12. However, lots of wing area and rather light at 8 pounds.

turnigy batteries arent that expensive as you know...so getting a couple 4s 5000's isnt that much either. Its all up to you tho.

Kahlog , thanks buddy , I will probably just buy the bigger batterys and stick with the 110 .and make the 8s 5000 as stated .
I love Turnegy but as you know Hobby King is now cut off to the states , I so have to check the USA distribution center . Hobby Parts site is more difficult to manuver when looking for batterys,
Sean , nice to hear from you , the corsair is great that is what my 5s 45c batterys are for , I am useing them in my Corsair and my CMP P40 .
The P40 is lighter but the power combo is good .
I have way to many projects on my table , this new Dora was a total impluse buy , I actually sold the kit last summer . I have the CMP Hellcat on my table and just finished my FMS P40 Foamy bash
