The model builds nose heavy as it is and I would not use the kit engine mount, but toss this out. It has been known to crack in time and several have failed. The kit supplied engine mounts are very heavy and I would recommend that you use a lite Du-Bro or Dave Brown unit. I used the Dave Brown engine mount.

I mounted both my rudder and elevator servo's in the aft fuse, and installed a different tail wheel assy.

I have installed three engines into my model, and it now has a Super Tiger .90 in the nose. I've no lead in the tail, and my first engine was a K&B Twister .61. The K&B Sporster is a very user friendly engine, and very reliable. I've use this engine in several models and it always surprised me with great handling and reliability. It is not a high revving engine, but mine swung a 13 x 4 and will give better vertical too with this model. I only used wood props on my gas models.

Find round brass tubing that will fit snug around your wing hold down dowels, and install the brass tubing. The hold down dowels will wear and change your wing incidence...and your model will fly like !#$%&*...mine wore almost half way through before I caught it and made the fix I've spoken of here. Ask me how I know... I would also suggest that you beef up the bulkhead that the wing hold down dowels penetrate into, with a small piece of hard wood. Place the hard wood on the top so that your brass tubed hold down dowels will rest against the hard wood and not auger out the holes were the hold down dowels enter into. This bulkhead is weak and needs added strength to support the wing. Balance your props...this helps.

Coat everything with in the tank compartment for fuel proofing...it will add longevity to the model...I do it to all models.

Toss out the fuel tank that came with the kit...mine failed. A Du-Bro 12 oz. dropped right in with out any modifications to the forward bulkhead.
