Thanks for your reply. Yes making a Royal P38 is a lot of work, I have a tt pro 61 and was looking to get an other one for the plane.But I have 2 OS 46 and I tough they would work.

Hay byjoe,
The twin OS .46's would be on the lower end of the power needed to fly this airframe. All the models I've seen fly of the Royal P-38 had .60 class engines installed. Now the OS .46 FX is a strong engine...and equal to what the .60 class engines were, back when the Royal P-38 first came on sale. T.T. Pro .61 is strong and a good engine for the money. MECOA sells the K&B .61 twister for $108.00...and its equal to the OS and the Pro T.T....but the K&B is lighter then all of them.

Hay byjoe,
Did you make a stand for your P-38... ? I made a stand for mine and it worked out just great for me. I got the idea from other P-38 builders and made my own stand. It took one day to cut out and assemble...and three sittings to clear coat. I can cycle the landing gear, as well as run the engines on this stand.

Enclosed are a few pictures of my stand and P-38 build. My build is a modified N.P. ARF that was seriously reworked. My stab is removable, the wing splits into two and both the nacelles and pilot pod are removable. My wings and pilot pod are flight ready and I'm in painting mode now with the engine nacelles and cowls. The flippen weather is not helping the finish painting...but as soon as I'm finished the painting-I'm done. I'm using Perry pumps, Sulivan on-board glow and Spring Air retracts (w/Robart struts and wheels). I side mounted my engines for reliability...I've had lousy luck with inverted engines.

Soft Landings Always,

Hey Bobby, That is a sweet Lightning stand. Thanks for sharing the idea. I am going to copy you.

Hi guy's...

I have the original marutake p38 kit...it is more han 10 years old. Finally I have the time to finish the kit .
The kit was disigned for a fixed landing gear. Did any of you changed this, and built retracts in it ?...is there space for retracts and is it keeping it's strenght.

Thanks,

Kor

I'm thinking of starting a Royal P-38 build this year and would like to use gas engines. Would the DLE-20s work or are they way overkill?

Hay Korvette,
The Royal P-38 kit can be modified to fit retractable landing gear. I've seen several Royal kits modified this way and not that really difficult to do. The Royal kit is not a large kit and things can get a bit tight in the engine pylons, but its doable. There are quite a few servoless electric retracts out there that would be a simple solution for fitting retracts into the Royal P-38. That is the way I would go if I ever build another P-38, for these type are much more simple to install, no airlines, tanks or servos to install.

Hay Kestreltalton,
There is no way a 20cc gas engine would fit into a Royal P-38. You might stuff in a 10cc gas engine...but the weight of the instillation may prohibit using them. A good 2-cycle 10cc nitro engine is the way to go. On your smaller P-38's weight becomes a real issue.

I'll definitely have to check the size. It seems like size might be more of a concern than weight in this case. The DLE-20 is pretty light; only about 200 grams more than a .72 4-stroke which is one of the recommended engines. But being gas you could get away with smaller fuel tanks. I think it would end up being only about 1/2 lb more in total for both engines.
