I have  seen many beginners  coming into this hobby  expecting zero damage  to  the aircrafts
EG
Nehutec ( Nehal ) : I crashed  and the servo broke  so servo is not good  .

Guys please try to understand even the best flyer  here has crashed  and learnt .

The Damage  is inevitable  basic laws  of Physics  do not  allow ZERO damage , these plane fly at relatively high speeds  eg  around  80 - 100 Kmph at the  least  hence on impact the  energy that has to be decimated is also  huge  relative to the size of the plane  hence  Damage is inevitable .

What SPAD's . ELAPOR  etc can do at best is minimize damage  eg earlier  a crash  of the kind Elapor and SPAD's take  would have left you carrying back a Balsa plane in a small box  today  with these materials that is not the case .

SIMS  further help to reduce this  loss BUT  PLEASE NOTE THESE CANNOT BE  COMPLETELY ELIMINATED

The problem is, if not many but most people think that flying a plane is like playing with an small RC chinese car. They think the plane moves ideally.front is front up is up and down is down . Most of my fiends think the same way, but when they try on my simulator then they come to know about it. As sai said a good sim would give a basic idea on what to expect on the first flight

Regarding breaking servos, nobody can help if it breaks due to crash, or burns due to stalling .

Quite agree I have had  quite a few guys coming to me to buy models they want to assemble and fly day after tomorrow if not tomorrow . In fact yesterday I had a couple of guys who came along to Chennai to buy Mr MOSS  for flying at a college   event  on 18th .

I have observed that Heli flyers  take crash damage  easier in the stride than fixed wing flyers wonder why

Coz Heli Flying is a lot more difficult than planes. So a Heli flyer is always ready to expect a lot of crashes at beginners stage 
Though crashes can be minimized by Sim pracice, training skid, lots of hovering and having lots of patience. But for most people like me, the patience part is lacking. and hence the crashes.

You mean - crashing at a college event on 18th?

When a heli is damaged, All you need is spare parts that you need to replace to get back in the air. If you have the parts, then you can be back in the air within an hour ( usually 15-20 mins )
You are not really repairing/or rebuilding here.
With airplanes, you need to cut balsa, join, glue, sand all the while ensuring that the weight doesnt go up and yet the structural strength is not compromised.

Since i have been into both, i think airplane crashes need a lot of patience.skills and heli ones need a lot of $$$$

Mostly true, not entirely though.  For example, one common fixing trick for a single break in the CF frame of a 50 size or larger heli is to take a long enough piece from another broken CF frame, cut/grind it to shape (cover your mouth/nose while doing this!), and then gluing it in place to that it stretches to both sides of the crack in the frame.  Most people also drill holes on both sides of the added piece, and secure them further with nuts/bolts.

In summary, it is a matter of how creative you want to get.  It is definitely more natural/frequent in the airplane world.

I will show you another example of such a trick with pictures later on.

hello to all members

sorry sai uncle if u where hurted but i was just saying that servos are really very delicate bcoz they where damaged in normal condition like I was trying to fly and i throw the moss in air as i have seen in videos and i was not able to control and it crashed nose first. now hitting the nose first it broked the prop first and the servo was also also damaged the gear where broken. so i just told that the servo is not good bcoz i should handle normal crash (i think). but the servos where delicate to handle the crash.

i know that the servo r delicate and get damage while it get surface hit but  this time there was no surface hit .

sorry again sai uncle

Reminds me when you said that line about asking an airplane-only aeromodellor to build a 60 size heli.
Wait till you crash a airplane that strips the landing gear out, breaks the firewall and crumbles the wing's landing gear/ribs/spars.
Need soooo much patience to get it all back. But thats what the hobby is all about !

I have had that on the first ever airplane I owned, was an ARF named "Hotpoint EP" (http://www.rcgroups.com/forums/showthread.php?t=396196), because it used the same power system and lipos as my Trex 450.  After the first crash, I had to rebuild the entire firewall / motor mount by cutting balsa (sheets, triangular and rectangular ones).  The balsa pieces that acted as inserts for the wings for joining them together also broke, so that was another thing to be fixed. 

I was initially amazed at how well balsa and epoxy worked, and how strong it became as I had used liberal quantities of epoxy. The power system had a lot of thrust to spare (and I did not know about the impact added weight all that well either at that time), so it was a fun day with epoxy, and trying to cut balsa in clean round edges so that the cowl would fit correctly.

After not flying it for a long time, I gave it away to someone who built a lot more than he flew, and he left our field for good last week for settling back in Chennai. He crashed it couple of times since, but for him, that is just more pleasurable time spent I expect to see him on this forum soon ! And he would be a new customer for Sai and Arvind

Learnt and crashed too

Since we are talking about crashing hehe..let me stress on something important..before buying a brand new plane, build a similar spad as per same specs and fly it..better to crash this than a brand new plane..

happy crashing..

Last Friday, we had a full throttle (right after take off) direct nose in crash of the AXN Floater, and the damage was almost nothing.  Similar stories are all over the place with it comes to models like Easy Star, Hawk Eye etc. So there is a way to learn without worrying too much about crashing. The cost is a bit on the high side on some of these, but it is well worth the trouble !

Nothing beats scratch building in terms of cost effectiveness though.  And if one can build a model like Ashta has (the lightweight pusher one), then that is the best of both worlds !

Hmm.... I am building and crashing. So at least as per the thread I am on the right track. Hope to learn to fly properly someday though :D:D

Don't you have any help? It would not eliminate but certainly  reduce the crashes.

Nope, no mentor in sight.... so keep making mistakes.

Pankaj ,
In my experience not having help  and scratch build  could result in a very very  long learning curve  as you are playing  with 2 variables
1) Lack of experience in Building  : hence improper build
2) lack of experience in flying

If I were you I would  tackle these one at a time . ARF for learning flying  and then progress to scratch build .

BTW this thread was started to get beginner to understand that learning this hobby  requires  perseverance and cost can be minimized but not eliminated.
