Kmac425,
My friend and I put together a H-9 Mustang and powered it with a Moki 2.10. The plane is a rocket with the Moki and I would even say overpowered. Requires some smart throttle management. It weighs 17# dry. Todd's motor weighs in at 38oz with ignition and muffler. The Moki weighs in at 46oz without muffler. Mustang has a 24oz tank.Add the weight of a muffler and a mount for the Moki and things begin to addup quickly. Todd's motor uses 1/2 oz a minute. I think it should be possible to save an easy 2# using Todd's motor.That is a 10% savings. The big Stang flys well at 17# plus fuel but would be even more of a delight at 15#.
Just my 2 cents worth.
Check out the Hangar 9 1.50 Mustang 2.10 Moki Build by Dobro for some great pics. Cool machine!!!
