hey Mike ,,
Best wishes on your test flight ,,, 130/lb should be plenty Guess I'm a member of the "Sorta Overkill Club " @ 450w+ but the MEga was the only motor I had on hand suitable for this plane .Then again I'm a little heavier... Throttled back with a 4300mah pack it's good mix of duration and performance ,,,"the grunt" is on tap if I need it . Hope you'll really enjoy this gal ~ Take care -HEnry Quote:
@ Tommy ,,, continued g'luck with the assembly , I found the supplied tailwheel too big as well,,, I found one in my parts drawer that's worked out really well,,,the wheel is pretty small. even though it's not the prettiest thing around it works great ,,, good thing I snapped a pic ,I need to adjust that collar ! |

On the 11x4.7, the watts are 384 and it doesn't take a lot of RPM's to fly the plane with this motor and prop. Its normally at 1/2 to just a little above for good cruising speed. I would have used an 11x5.5E had it fit in the spinner. A four blade prop would be a no go as I dont have landing gear. I know pitch is related to speed and that is why Im using the 11x4.7. Anything higher and the plane rockets around too fast for anything close to scale. |

Thanks for the photo. I may just use the tail wheel provided, my field is rough on landing gears. The trip to the LHS almost proved to be very $$$, they had the new Hanger 9 Sopwith Camel in stock. Where have you guys made exit holes for cooling? Thanks Tommy D |

Thanks for the tips on the cooling holes!
Getting ready for the NEAT fair so not much time has gone into the Spitty recently. Tonight I decided to glue in some velcro and check to see where exactly I'm at , C of G wise. With my pair of PQ packs all the way forward the model balances perfectly at the 7.5CM mark. Just 1 problem though.... I have yet to install the tail wheel! Ill see what kind of surgery it will require to get these 2 brick packs more forward. Worst case Ill beef up the front mount with some triangle stock and add an ounce or so up in the cowl. Gosh... I hate dead weight! Tommy D |

Yeah, again another Brushless Motor that is perhaps light in weight and thereby causing the model's CG too AFT.
I would certainly consider moving those battery packs forward and eliminate anything in there way forward! Lets not have an episoide of handful ugliness during take-off! |

2oz on this one is no big deal...I knew I should have the larger motor if just for that. Mike |

Good news gang - Sparky is going to do a cowl for me.
For those who don't know Keith (Sparky) he is a master model builder and all around good guy...I put a couple of pics of his recent work just to let you know his cowl should be "just fine"...... I will post pics and instructions on how to get the cowl from Sparky soon - stay tuned! Mike |
