We finished up Joey Tamez Viper Jet and took it out this weekend for the maiden.
Very uneventful and we were surprised that the gear seemed to work no problem(we have seen some struggle). We used BVM high flow valve and two air tanks. Worked great. One door did manage to depart in flight.
We installed a P200 since we had one available and we used a BVM P200 bypass and a BVM F100F tailpipe I had from a F100. They dropped right in, perfect fit. Very low temps, in the low 4's.
The airplane is very nice, just a bunch of little aggravating issues that are easily corrected.
Couple of things to look out for:
MOST IMPORTANT!! After only 4 flight the wing retaining aluminum sleeves were nearly pulled out of wings. Couple more flights and the wing might have slipped off!!! Wing gap kept growing after each flight.
Wing tubes and stab dowels can slide into wings unevenly. We glued the stab dowels permanent.
Been mentioned here ALOT, but there are many hard points missing in flying surfaces.
Cockpits look great but are made out of some low grade plastic and wont last. Before the first flight they were pretty beat up.
canopy glass very low grade soft plastic
fin missing most of glue inside and main former was detached. We changed to pull pull with solid carbon plate through rudder.
cockpit started deforming in sun
Landing gear mounts are insufficient. One wing had a broken former glued in place. No support at all. We added carbon support braces.
Some of the pro version work was a little sloppy and our white version had white spray paint covering the proversion work done. Fit was good, but whats up with the white pray paint?
Nose gear door cylinder was just glued to fuse wall with no support. Popped off before was even flown.
Winglet holes too big on one side so when tightened they gapped really big.
Tanks create alot of back pressure when installed per plans. Have to pump very slow. Bottom tank want to start balooning.
Intakes glued very sloppy and look nasty(INSIDE). They are very rigid though and feel very solid.
PROS:
plane comes out CG perfect with little to no weight with batteries in nose.
Big and pretty
Wings stabs and fin fit to fuse and front to aft fit perfect. Overall excellent fitment of all parts. Canopy little off.
Nice gear, struts wheels and brakes
BIG!
Flies beautiful and very stable. Very wide envelope.
Breeze to land.
Easy to assemble.

Overall very nice aircraft, would probably fly great even with P120, Joey took off half power and flew there the whole flight. Half power take off climbed out very nice. She needs alot of flap deflection to slow down well for landing.

Hope to get it in the air again this weekend.
