After one assembly I put them in a box far away on my shelves.

Dont know why they do not have more weld going around....actually I do know why...time and cost...but the small amount of time spent would make it much better.

Status: offline 		I just installed my evolution 26 and realized that the evolution wrap around muffler doesn't quite fit! It butts right into the firewall. Did anyone do some real modeling and cut away at the fire wall? I would prefer to purchase a muffler system for the 26 that I wouldn't have to cut the firewall with - any ideas??

Status: offline 		Well, I did attempt a 2nd flight today...............

but.........

Got it all put together and set the battery on a charger to peak. Went and flew another plane while it topped off. Nice wind, about 5mph out of the south.

Got the P-51 fueled and then someone else with a gas plane wanted me to wait so they could get a flight in before I "hogged the runway in order to be able to HEAR the motor while in flight". So, by the time this gasser landed....20 minutes later....winds had shifted opposite direction and now were coming form the north, northwest.
Not optimal as Im not used to taking off right to left, but I was confident I could manage it.

Got the plane running and taxied it out...was a little hard to keep straight so aborted the first take off attempt(winds were a litte more from the west, north west now....
gasser guy suggested I throttle up a lot faster to to get rudder authority......
Got her lined up again and started the roll and shouldnt have listened to him...........
plane ground looped and went off into the weeds and tore out the right wing oleo strut!

Advice to all......dont listen to a pattern gasser flyer even if they mean well.....you know your plane better then they do and just do what you know works for you. I'd been ok had I just slowly advanced the throttle up instead of sorta throttling up at first then mashing the throttle like the gasser thought I should do.

Status: offline 		Ouch! Sorry to hear of your Frankie's trip thru the weeds, and subsequent gear damage! Did it pull the strut out of the retract, the retract out of the wing blocks, or the wing blocks out of the wing??? Hope it's not the last one!

Had I been able to fly yesterday, and been out there, I would have strongly advised against a sudden throttle-up on the 220! I've found the torque turn is far more pronounced when doing so, and is very difficult to control with the short moment arm from the CG to the tailwheel.

And, in contrast to a long-tailed, "large rudder-ed" gasser, with a sudden throttle-up, Frankie's rudder authority doesn't kick in early enough to overcome the 220's desire to pull the 'Stang in a circle.

I've settled on a gradual throttle-up for take-offs, all while feeding in a bit of right rudder that, for the most part, has enabled me to keep my Frankie on the runway (and often, near the center) for my 10-11 take-offs,...so far.

Good luck on the repairs; hope you get her back in the air soon!

Rip

Status: offline 		Had you been there, you would have been my co-pilot of choice, not Jim as he knows nothing about glow motors, let alone 4 stroke torque monsters.
Anyhow, I've already fixed the damaged. It was minor. I did have to completely replace the retract housing, but the oleo was fine. Kinda funny how things work sometimes. When the incident happened, as the plane went into the grass/weeds, I saw the oleo strut actually being flung forward as the plane nosed over quickly. About 5-10 secs after this, a huge gust of wind from the west came though and I bet it would have really caused a more severe problem for the plane had it just lifted off or been on the initial climb out.

My only concern so far with the retracts is the plastic black linkage thats on the retract servo arm that connects to the metal clasp part on the retract mechanism. I can see after some use, that the plastic part can and probably will become deformed and may either come off the servo arm or snap.

Status: offline 		Glad to hear the damage was minor!

I noticed from my hard landing somewhere around flight number 9 that the retracts (specifically, the flanges that bolt to the gear blocks in the wing) are fairly easy to deform. Had to remove the retract, clamp it in a vise, and carefully straighten the flanges back to their original orientation (and by doing so, making them weaker to resist future rough landings, of course).

Handling side, and especially front/rear torque loads, is not the forte of the H9 stock gear.

Judging by the ruggedness of the Robart 551/660 pneumatic system I'm now installing in my smaller 'Stang, I'm sure I'll upgrade Frankie's gear sometime in the not-to-distant future.

Did you ever get to try your 18x10 prop? I've been running the 17x10 Bolly, but picked up a 16x12 APC to try next. Will let you know.

Nick,

No, haven't had time to swap them out.

Had a great flight with Frankie three weekends ago on the 18x8, but was out on vacation the last two weekends.

Next weekend is Warbirds Over Denver, and I probably will stay with the "don't fix it if it ain't broke" strategy and stay with the 18x8 for that event. Perhaps the weekend after that...

Rip
