World Models p47 1.20

I just purchased a p47 1.20 from world models.

Following are the specs
Wing Span : 70 in / 1780 mm
Wing Area : 893 sq in / 57.6 sq dm
Flying Weight : 10.7 lbs / 4850 g
Fuselage Length : 62 in / 1580 mm
Engine Required : 4-stroke 1.20 engine

Would appreciate if someone could comment on the following questions

Ideal Power Plant
Option1: Saito 125, which is considerably lighter than OS four stroke 120 about 200g lighter. Do not want to add dead weight so will I be able to balance it with battery placement? Does Saito 125 will be enough to pull the plane this size?

Option 2: The newly released DLE20? approximately same weight as OS FS120? Will it have enough power to this plane?

To save some weight and to use some of the servos that I already have I am planning to use Hitec HS5345 servos on all control surfaces except retracts? Do you think I will be alright with these servos.

Any other thing I need to be careful about while assembling this plane?

Thanks in advance.

DLE30. I have a RCGF 26cc on mine and it's a dog. One of these days I'll get another cowl and go 30cc.

No real issues with the build, don't get too crazy with the heat when you go over the covering - it's pretty thin.
