I have a Saito .72 on mine. I moved the engine and cowl forward about 1/4" more than the plans call for. I was worried about adding weight. With the engine out the extra 1/4" and the battery at the back of the servo mount it balanced perfectly. I also used a Kleet tail wheel. I don't recommend this. The wheel pants drag at the rear. The stock tail-wheel would have raised it enough to stop this. Your right about the landing. the wires are the culprit here. They are to flexible. If you try and land real slow it won't tip stall but will turn flat Mine goes right and the rudder won't effect it at low speed. BUT... if you try and come in fast the pants dig in as the gear flexes back. there must be a happy median here. I haven't been able to find it but only have 15 flights on mine. Speed is not a problem with the Saito. Mines not broken in and at a rich setting it's plenty. Once I lean it out it should be a bullet.later daveo
