HOT ZIGGIDY

Successful maiden today

Motor MVVS 26cc 160 glow and tuned pipe 5% nitro fuel with 10% synthetic and with 18*10 master airscrew and 55 inch 1400mm Ultimate meant for 90 2 stroke or 120 4 stroke

Fairly conservative spool up to get a good line down the grass field so acceleration was fairly rapid
tweaked the elevator up a tad unstuck after 30 feet and pointed the nose upwards and opened the gas to 3/4 power and ballistic ally arrived to 500 feet in a couple of seconds
I figured best to get height ASAP in case motor acted up and quit but it ran smoothly all the way through the flight

Did a few loops and rolls high up with less than 1/2 gas and a few low passes at 1/8 gas and it was still doing maybe 60 MPH passing the runway

The wheel decided to fall off SOB[:@]

Landing was made engine off glide in and as the undercarage was held on with nyol bolts to shear on rough landing they performed to specs and sheered off having absorbed the fairly abrupt stop from single wheel set up

So off to the LHS to buy another wheel until i can learn how to hover 3d take off and hover landing I wish

grin factor from such outrageous AWSOME excess of power and dropped jaws of the other club members worth every cent

Just got to figure how to stuff in bigger tank than 16 onz preferably 30 onz as fuel seemed to used at more than 1.5 onz per minute WOT and flight time sub 10 minutes and landed with fumes in the tank so 30 onz should give ~20 minutes

I will also look to make the bigger tank with fuel pipes able to toerate gasoline fuel so as to try out a 40% gasoline 60% glow fuel mix to keep costs down a bit but might suffer power loss of 5% from gasoline fuel component but figure plenty of excess to power to lose
