Converting Wattage Crazy 8 to Nitro.

[jlnajarro]

I’m looking to convert a Wattage Crazy 8 to Nitro using a AP .15 and 9x4 APC , 250 MAH Batt, 555 Hitech receiver , Cirrus servos CS-10/alierons , CS-10/throttle, CS-26/elevator, CS-26/rudder.

Total weight with 2 oz of fuel = 23 oz.

The spec says it should be 26 to 30 oz when going electric.

The problem is the plane keep ballooning to a vertical position, when I cut the throttle. I have tried adding a bit down thrust to the inverted installed engine but it still seems to have the same problem.

I'm using the recommened CG in the Manual.

Any Suggestions ?

If you have to have a lot of down thrust to keep it from climbing it could be the wing incidence. If it is to high which would cause it to climb or just nose up when the power is reduced. Just my .02
