How big are the .10 Engines. Like os .10 engine. Do i need micro servos for a plane which is running with a .10 engine. how big plane would be appropriate for .10 engines??

That is hard to answer because of the great variety of models. Some planes have low wing loadings and large wing areas that can fly with a small engine while a higher wing loading from a smaller wing area means a hotter plane. Motorgliders and Old Timers could be 550 to 600 sq. inches wing area. The biggest I have seen is the acrobatic slowflying Puddle Jumper with 800 sq. in. area. Trainers go from 325 to 425 sq.inches while I learned on a Tooter which had a 600 sq. inch wing. A hotter plane, like the House of Balsa Extra 300L has 280 sq. inch wing. I think it makes more sense to pick the model first and then to select the appropriate engine.

Definitely use smaller than standard servos which can be a big weight saving.

i bought a tiger moth .10

the mistake was.. i thought that i can still use my existing . 40 airplane things like servos, battery and reciever.

now,.. instead of saving for small model, i have to buy 5 micro servos (expensive) and smaller pack of battery.

thanx for replying poji,
that is a really good plane. did you try to fly it yet? how slow it is? i want a slow plane. but probably that biplane would need a experienced pilot. i need a trainer.


i was wondering if i have to use micro things for that size of an airplane. you were helpfull thanks. Since this is going to be my first airplane i will go for a smaller engine, and micro stuff.

If you are in a club which will provide you with an instructor I do not recommend such a small plane. No instructor will look forward to flying anything that diverges much from the usual .40 size trainer. The smallest size I would recommend to use is the Sig LT-25 which is a superb kit and gentle flying plane. Try not to get far from mainstream practices if you want to learn to fly RC with minimal pain.

dsegal,
You realy make me think about this. im sure you are much more experienced.

like i said i dont have a club and i dont have a so much chance to find an area so big with a runway. i wanted to be able to fly it some open areas next to my town(not close to public i am aware of the danger).

i was looking for a small engine like .10 or even smaller to make a plane considerable as a park flyer. but as i read your oppinions i think i wil have to wait a long time to find a club.

well i guess i found a club in my town. i really tought that there was nobody flying here in cape. but we even have a field. i will try to contact them. thanks alot for every one tried to help me.

encan, there are 1/2a (.049-.061) trainer planes, like the Ace series , whizard or grasshopper, you can see them at quantum models or the Herr kits (same place) , I have a Norvel .074 on my Ace whizard, it is a very popular kit,, go look at the 1/2a forum and do a search, some do fly at ball fields and parks, but I stick with the flying fields,, the whizard is only $35 from quantum and is pretty complete.....Rog
