How did the bird handle when transitioning from displacement speed to planing? Any tendency to submerge?

Lovely job.

Status: offline 		Bob, I take it you mean from taxing out to actually on step? Normally you would hold elevator in to push it on to step then release the evevator to then progress up to take of speed on full power . . . thats way I did it on the first couple of take off's with no tendencys to submerge, then I realised that holding the elevator in had no effect, but the plane still jumps up on step and takes off the same . . . I had the biggest grin I can tell you . . .

Build one!, build it light (mine was about 4 .5 lbs), build it with ailerons and run with 2 x .10's - I flew it half a dozen times and loved it every time. I wished I had used skinning epoxy and light weight cloth over the forward section of the hull as I sheeted my Cat with 1/16 balsa not 1/64 ply and I may still do, but apart from that i'm well chuffed !

Is anybody building .10s other than the OS 10 LA these days? I don't know if two of those would be enough. Maybe two of the 15LAs.

Status: offline 		I think that the 10LA is just a new version of the 10FP both are plain bearing engines with the same displacement, if I was building again and failed to find these 2 at a swap meet I would have just puchased a couple of 10LA's instead . . . I have 2 .15LA's and 4 x 25LA's all are very good engines . . .

Status: offline 		I'm glad you knew that, as I was not familiar with the FP series.

I really like the LA engines, as well. Properly adjusted, they refuse to quit. I have a 65LA on an RCM Ugly Stik that is a real champ. I've lost track of how many airplanes it has been on. At least 3, maybe more.

Just a couple questions:

Your throttle servos look like sub micros, is that the case?

2 or 4oz flex tanks for fuel?

I'd like to go the micro/sub micro route on throttles and ailerons, but I got burned once using plastic gear micros on a glow plane. The vibration ate the gears. Ever since I've used the HS81MG (metal gear) on small glow models. They are heavy, tho.

Status: offline 		I actually used some metal gear servos from Air-Craft World, very good price, good quality and excellent delivery both cost and time, also no import duty

Waypoint 092MB for the throttles (metal gear)

Waypoint 150Power for the Ailerons (metal gear)

Air-craft World

The tanks are 2 once slant as suggested on the plan . . . I also put in about 3 degrees of out thrust on both nacels.

Go on, build one - you wont regret it . . . [)]

I have used the Ripmax SD200 in glow models with good results and I dalso use the HS 85BB and 81 BB for throttles, although if I had to buy them for a job as apposed to having already had them instock then I would def go for the way point servos . . .

I have just bought another 4 x Waypoint 150Power for my 72" span Canadair water bomber, that is going to be powered by 2 .15LA's or .25LA's - I have both piars on the shelf but at the moment can not decide which way to go with it . . .

I think I'm going to try those- they're less expensive and lighter than any of the Tower offerings in MG.
