good evining fellow modlers i am new to rcu so bere with me i purchased a seagull model razzel to fly 3d with so far it is agreat 3d model. i have a o.s. 91 surpass with a apc 14-4w prop would like to get some input from other modelers out there on the performance on the model servos radio weight mods. thank you for your time.

do a search on razzle. There's a lot threads on the Razzle.

I have one (my second, as the first one found the fence at the end of our field on a downwind deadstick landing) with an O.S. 91FX. Came out nose heavy. Needed 2.5oz lead in the tail section of the fuz to correct. CG is at the rearmost position mentioned in The Book. Prophangs at half throttle on a 16 x 6 prop. Lands REAL slow. Weight about 6.25lbs. Nicad (1700mAh) mounted at rear of cockpit section to help with less lead for CG. REALLY flat spins!! Prophangs OK. Harriers are "fun" as it's difficult to stop it flying.

I really like mine with a Saito 100 up front. I found that Harriers and the like are made much easier by mixing in spoileron with the elevator. That is up elevator with up spoileron. It makes it Elevator really nice. It has made all the difference in the world. It also tightens up waterfalls. I use a 16 x 4w with my 100. It seems to me that the 14 x 4 would not be enough prop for a 4 stroke .91. Just my 2 cents.......even though it is probably not worth it! LOL

Well I have the exact same combo w/ OS 91 surpas and the APC 14X4W....perfect match.
Hovers at barely half throttle.
Absoutly unlimited vertical.
Never had a over heat problem.
200 flights now since last Feb.


Love mine.
