I'm almost done with my FK, so I'm about to order the engine, servos, receiver, rx battery and wheels for my Chipmunk and I have run into a dilemma.

I was going to order the Saito 1.00, but then I realized that the newish 1.25 is a bored out and reworked 1.00. It weighs about 2 ounces more and delivers A LOT more power. Now, a 1.25 is going to seriously overpower the Chipmunk, of that there is no doubt. However, the 1.25 could prove useful in a lot more different planes than the 1.00, and later down the road might prove a better investment. What do you guys think? I could buy a 1.25 and have a versatile, lightweight engine that will work in other planes if I choose to decommission the Chippy, although it will be severely overpowered, or I could buy a 1.00 that may not work in as many models, but would be a perfect fit with the Chippy.

I have decided to use JR DS3421s for at least the ailerons (dual), and if I can afford it I'm going to put one each on the rudder and elevator.

Think a 1400mah NiCd or NiMH rx battery pack would be enough for a full day of flying (say, 1.5 hours before it needs a charge)? The lighter the better!

Anyone have a recommendation for super lightweight tires?

A fiberglass cowl from Fiberglass Specialities has already been ordered. I may get the wheelpants too but not sure about that yet.
