That is frustrating. I am actually giving thought to building a top hatch given that I plan to use 2 4s 5000 lipos. Given where you are in the build, I would try to load the battery from under the wing. I just finished skinning my wing. The Robart retracts work great. This is one project that will never seem to end. In the meantime, I have plenty of planes to fly in the meantime. Weather at our field today was 58 and sunny - got to love those conditions!.

Stay well and happy Thanksgiving to you and your family.

Yep sure is frustrating...I would hate to add weight in the tail to balance her.

I might look at making a removable top cowl but it will be a major retrofit...arrgh. If not than will have to load the battery by taking the wing off or rigging up a charging port. I can always fly my other planes or helis while the P51 battery is charging. In retrospect I should have clued in that the battery should be were the fuel tank should have been.

Thanks for the warm cheers,

Gord.

Hi Gord - happy new year!
Just checking in to see how you are coming on you P51? I have completed my wing - working now on the fuse. I was sidetracked from buyilding a F14 Tomcat and a L Bee Delta wing. both are lots of fun to fly.

I have a Top Flite ARF Mustang with a monster power 60, 15X10 prop and 6S 4000 lipos, plenty of power and duration my inflight amp draw is 37 amps crusing around at a pretty good clip. I think a 110 would be way too much power.

I am almost finished with my TF P51B. I am equipping it with an E-Flite 110, Phoenix HV85 AMp and not sure yet what prop. I am also using (2) 4s 5000amh Lipos. I based my power plant on needing 100 watts per pound and I think this plane will weight around 11 lbs. I am running 8 servos and Robart retracts. How many pounds is your plane?

oops - forgot to mentioned that my P51B is a kit and not an ARF. Maybe that is why you can use a 60.

The MP60 is good for 1200 watts, I didn't weigh mine afraid to but it's somewhere in the 10lb range.

Sorry I am running 22.2V and hitting about 55A on the ground WOT so just over 1200 watts.
It flies much lighter than it is, floats in for landings nice and easy.

How much flight time are you getting with that combo? Are you running a separate servo battery pack or are you using a regulator?

Hi Ron,

Sorry for the very late reply but I didn't get notification you updated this post.

I did see an update today though.

To answer your question...I started sanding my P51 the other day...the weather was beautiful and I can work on it in my drive way while watching my son play outside.

My fellow club members are bugging me about it so I am pushing for a late summer maiden...cross my fingers.

Thanks for the Happy New Year Cheer.

Gord.

Dude - I can't believe that I will finish mine before you finish yours! I just finished painting mine and just need to apply the decals and wing servos. I will send pictures soon.

I fly for 5 min until my timer goes off and land so around 6-7 min. Yes I use a separate battery pack I have electric retracts and I didn't want to run to LVC and get stuck gear up.

Got it - I can't wait to get mine in the air soon. I plan to post pictures once the decals are on and servos placed in the wings.

Hi Ron,

Wow...nice work mate, yep I am embrassed to say mine still is in the sanding stage...my fiberglass job was horrible...so most of it is sanded it off...you did an amazing job...congrats...can you finish mine :-)

Just kidding...I did some more sanding today...my club mates are ribbing me about it...so I went out and bought a Phoenix Model Yak 54 to prove that I can finish the stang this year and still have time for ARFS.

Gord.
PS - Love the details...well done !!!

Thanks Gord - this was my fit kit attemp and I learned a lot. Just now trying to decide if I should go with an 8S or 9S battery with my E-Flite 110 motor. Also need to match the right prop. Need enough watts to lift this 13 lb beast - yes 13 lbs! It came in heavier that expected. Send pictures when you have the time.

Cheers,
Ron

A sanding we will go...a sanding we will go...hi ho hi ho more sanding to go... :-)

did a few more hours sanding last night...my buds are bugging me that I am too picky but the finish has to be good or why bother.

I am pushing hard to have it done by late August...won't be nice as yours though but it will be finished so I can move on...I promised myself no more planes until this one is done...so I am motivated to finish it.

Did you maiden her yet?

Go Canucks Go...if you are a hockey fan you will know what I mean :-)

Would you believe July?

I know I know I know...she should have been done many moons ago but I started to fly my helis and was flying almost every weekend and now it's windsurfing season and the "nucks" are in the playoffs and I just put together a new gaming pc and and and and :-)

The goods news is to me that is...our flying field is shared with another group and they have priority weekend hours, ie: from 11am till 7pm, in other words I have most of Sat and Sun to sand !!!!

Cheers,

Gord.

You go dude - sand away!!. Just came back from 2 days at SEFF...the largest electric RC show in the country. What a blast. What I was most amazed about is the size planes that are now being flown electric. Very cool.

I have not - I bought (2) Zippy 4S 5000 20-30C (to run in series) to power the plane only to learn that these batteries do not pack enough power - bummer. My $195 battery special turned into a $400 purchase as I had to buy a different brand. I bought (2) Thunder Power 4S 4300 40-60C - they should arrive soon.
