RE: wroldmodels p82 landing gear
Ok Guys...
I'm pulling my K&B .48's and going to Evolution .36's. I'm very happy with the .48's...but the model is still nose heavy. I also pulled my Perry pumps...for I'm trying to simplify the model and lighten up the beast. The Evolution .36's seem to be very light and with very good power...better then most .40's, but much lighter. I'm also going to run two 6 chanel receivers and two light weight Nihydride battery's for the recievers. This will end up being lighter, for all the cables I run in this model weigh more then a second receiver. I bought two new cowls for the model and I will either go with the standard mufflers or pits style if I can get one for the Evo .36's. I'm trying to get the model as light as I can up front and save as much weight as I can. I'm pulling my battery back up system I had installed and going back to Robart 2 1/4" wheels. The scale wheels really do not hold up well, but they are the grippiest wheels I've flown on the model and if you glue the Robart wheels together on assembly, per Robarts instructions, they will last a while...but do keep an eye on their ware patterns. The Robarts also have the widest foot print of any scale wheel i've found on the market, and this is quiet a plus on this model. I do fly off of a hard serface runway, but our club does not have a really long run way, and obsticals at both ends of the strip.
The K & B .48's are an awesome engine and mine are Mr. Lee's reworked jewels. Great power and more reliable then the Fox .50's. The Fox engines put out good power, but I had reliability issues and I'm not sure if it was the Perry pumps I had installed with them, or the inverted position of my engines, but more then half my landings were single engine. The model has the best single engine performance of any twin I've ever flown...I must have at least 40 landings single engine.
Flaps are another story...the nose will pitch with more then 15 deg. of flap depoyment. Flaps will slow the model down and make for slower approaches, (if you really put some flaps down, more then 35 degs..carry some power on approach). The model is rock solid in all flight envelopes, but be ready for quite a nose pitch with a large degree flap deployment. I have a good bit of elevator trim set up with my Tx, but the required elevator trim changes as you deploy the flaps. In other words, the elevator trim requirement is not uniform as flaps come down. You will need more elevator trim hrough the mid range of flap deployment and less as you reach 60 degs. or more.
I have no experience with O.S. LA .40's and can give no advice to their use in this model. All I do know is that this is one very impresive model in the air and the longest lived ARF I have. It's now almost three years old, with two landing gear system rebuilds and one wing repair, that was more then minor ding. I've managed to total two P-51's and two P-47 ARF's...but my WM P-82 is still with me.
My model has a bright yellow tail and D-day strips...OK...not scale or any where near anything scale, but it looks great in the air and very visable at all speeds. The model is not very scale, with the aft fuse way to short, but it's the only twin mustang on the market that I know of and it has the very managable single engine performance.
Soft and gentle landings always,
Bobby of Maui
