HI WHAT is the best airframe and engine combo (include prop used and brand ) in the 60-90 size ( smaller size ) airframe that can do the aerobatics required for IMAC flying i am searching for the best performing airframe in the smaller 72 inchish size ENJOY BEST REGARDS TONY

Tony - Take a look at the OMP 67" Fusion. With a 90 2-stroke (14x4 APC) or 120 4-stroke (16x4 APC) it's a plane that's hard to beat on either the precision or 3d end of the flying spektrum. Just set your CG up according to your tastes. Hard to beat in that size.

Geeze, your kidding right? Your steering this man to a 60-90 sized "Profile" plane for the "Best" solution? Check out this [link=http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXYSU7&P=7]AeroWorks .60-.90 Extra 260 QB ARF Red 60"[/link]. Power this baby with an OS .95AX and an APC 13x9, 14x6 or a 14x8 prop to get started...now your getting into the "Best" kind of 60-90 sized plane for IMAC...or with the right CG and throw settings, this combo will make a decent, entry level, 3D plane as well! PS...now if you really want to get out there with this plane, throw in a OS 1.20AX and let the fun begin!

Not kidding. Of course now there are 2 good aircraft recommendations. However, having experience with both I'll stick with my recommendation.

OOOOOK then...Have a nice day[sm=75_75.gif] LOL

I will and do most of the time. Sorry I got you fueled up over this. I was only giving one option to a fellow modeler. No need to get personal over it.

Tony - my apology that your thread went this direction.

tony0707

hi NO PROBLEM GENTELMEM-thank you both for your helpi had the aeroworks in the back of my mind when i posted this thread the plane really does perform for its size and i do like the fact that it has a scale look-nice price at 190.00 with glass cowl and pantsthanks again for your input

FlyerRick

NP guys...takes a lot more than a forum post to get me off and running. Have a nice day![8D]

PS...you bring a profile plane to an IMAC event, I'll beat you hands down EVERY TIME! LOL

Tony,

Wildhare makes some nice airplanes that just about fit your category. The Baby Edge and Baby Extra are both at the upper limit of wingspan you are talking about and you can fly them on a glow in the 1.20 size range with plenty of power. I've had an OS200FS on my Edge (it was the only plane I've ever owned that I thought had truly to much engine on it) but I hear the Saito 125 flies it very well for IMAC or 3D. Having said that I would encourage you to go with a gasser. Wildhare sells a 30cc that works well for these planes. I switched to an MLD 28 that you can get from Cermark and it is still unlimited vertical. I encourage you to think about a gasser because if you want to compete in IMAC you will burn a lot of fuel at practice and Gas it so much cheaper than glow. That's why I switched. For just 2 or 3 gallons of glow fuel cost I could pay for the gas engine instead of the glow and run LOTS of gasoline cheap! Obviously I lost money on the deal as I bought the 4 stroke then changed but if you buy the gasser up front you will save money in the long run (and not very long at that). My plane came out to 10lbs and the power is sufficient to pull straight up, THEN roll in throttle and climb, throw in a snap or two and accelerate again straight up.

FlyerRick

Well put jsallade...This is a real good suggestion here Tony if your seriously concidering IMAC. I have a WildHare 35% Sukhoi in my stable and it's truly a well built and great flying plane...at good prices too!

PS...Just to throw out there...For what I spend in glow fuel in a 2 month period, will power my gas planes for a year! Other side of the coin...Wait to you see the difference in your "clean up" between a gas and a glow plane after a day of flying! LOL

Tony.

A couple of important points that have not been mentioned.

Generally, in IMAC the model has to be a scale model of an aerobatic airplane.
The outline of the plane can not deviate more than 10% from "true" scale.

The only exception to this rule is for the Basic class, where there is no scale requirement at all.

Therefore, for Basic, (in my opinion) the "Best" plane would be the one that flies the best. There are no model planes that fly better than Pattern models.
A 2x2 meter pattern model, preferably with an electric motor operating on 10s lipo, would therefore be best.
A "Profile plane" will fly the Basic program quite well, but not as well as a pattern model.

For all the other classes, it has to be a scale model.
